Macateboards Can be collected for any device. They are popular with novice electrical workers and experienced masters. They are collected with soldering and without soldering. The first durable and can be used as the main fee, and the second are more comfortable in assembly due to the exclusion of soldering works.
To start the production of any product, it is necessary to make it layout, and then, appreciating the productivity of the product and its other parameters, proceed to the release of the series. In this case, you save money and time. But the prototypes are made not only in production, they are also widely used in electronics and, first of all, this is due to the release of dummy cards.
Suppose you are going to make a new electronic device. Previously, the prototype of the bold fee was the appearance of a rectangle from the cardboard, in which the holes were made and the radio elements connecting between themselves were inserted there, and then its work was checked. If the functioning of the device occurred normally, the production of the main board began using the appropriate materials. Now the task is somewhat simplifiable - the market is actively sold by bias with already prepared holes and tracks, which can be found in specialized stores, for example, in this http://makerplus.ru/, where you can choose the appropriate option.
What bold fees are
Macateboards are made without soldering and soldering. The design without soldering is a plastic housing with numerous holes with contact connectors. Details are mounted in them. Holes are designed for wires with a diameter of 0, 7 mm. The distance between them is 2, 54 mm, this is enough to install the transistor and other elements.
Power tracks are designated blue and red lines. The number of points for connectors may vary from 100 to 2500 pieces. The principle of working with such a board is simple. You mount the electronic elements in the desired holes and connect them with regular wires, or buy specially prepared wire jumpers. If the scheme is collected incorrectly, then you disassemble it and install it again.
Soldering
This board differs from the above option that the elements installed in the housing can be soldered. In this case, you can use it not only as a layout, but also as a real product. True, then the fee will have several large sizes. In addition, soldering structures have a lower price.
Boards with soldering, which, by the way, can be purchased on the page of the online store http://makerplus.ru/category/breadboard, have holes for wires with a diameter of up to 0.9 mm and are located in one-inch increment (2, 54mm). On the one hand, the design is located straight insulated foil lines, and the radio elements and jumpers are installed on the other.
- Immediately cut the board to the desired size. For this, conventional scissors, cutter, hacksawa are suitable. You can even just break her over holes, but then checking the edges.
- If you are not going to use the board right now, then do not touch the places with the foil once again. Hands can be wet, which will lead to corrosion of the surface and deterioration of contact.
- If oxides or contamination take place, then clean them with zero sandpaper or ordinary eraser.
- Radio elements are installed from the side where there are no strips from foil. The conclusions are populated into the holes and searched from the reverse side.
- Blue color conductive tracks denotes "minus" schemes, red "plus", and green is used at their discretion. The tracks are marked with the same side where the foil is located.
- The most important positioning of parts occurs in a vertical position, since in this case the error will lead to an incorrectly assembled chain.
Consider that the bikes of both types can have a groove on the sides. It is necessary for those who collect big deviceconsisting of several modules. The grooves allow you to collect one large fee of several small.
In this video, the lesson tells about what covertoamy dump trucks and what they are used for. it required tool Not only for beginners but also for experienced users of the Arduino platform.
Buy Macateboards
You can buy insane dump trucks in the radio component store, on a radio station or online store. But the most profitable option is of course alikexpress. There is huge selection Macateboards,
as well as not high prices. But you need to be attentive and buy only reliable vendors. Below are the links to Alikexpress:
Breadbord (Breadbord)
Chimunical dumping fees are very convenient in Arduino training and prototyping their projects. Thanks to these fees, it is possible to collect quite complex schemes and at the same time do not even take a soldering iron. You simply insert the elements of the scheme into the holes of the dummy and everything works. Simple projects can be done even without using wires. It greatly speeds up the learning process or creating the prototype of your device.
You can assemble one project, then disassemble and collect already different. You do not need a soldering iron and consumables. Also before the manufacture of a full-fledged device, it is better to collect his layout on an invisidious dummy. It can identify shortcomings in the scheme. It will also help to write a firmware, as we can use debugging LEDs. Only after you collect the prototype, write the firmware and make sure everything works as you have thought, you can collect the final version of your device.
How to use a bullshit
Very simple! The main thing is to remember how the holes of the layer are connected. Everything is simple and understandable there. At the edges there are horizontal power lines, they are usually marked with blue and red colors for convenience. And in the middle there is a lot of vertically connected lines of 5 points. The image below shows the pinout of the debris.
Why do it? This allows you to identify disadvantages, modify the scheme, and then when the device will be debugged, transfer it to diluted pCB from foil textolite. Because debugging and make changes to the device, the laundered on the etched board is always much harder. Of course, in this case, you can change the scheme, cutting a part of the tracks, attacking the details on the installation by the press, and so on, but this is an extreme case.
Now there are many excellent collet batteries, at a low price, especially if you purchase them without connecting wires. An example of a device collected on this board can be seen below:
Consider how collet battle boards are arranged, they use spring-loaded contacts, connected to 5 pieces in a row of tin contacts, they are usually vertically:
Also, the board provides rows of holes for power supply, (usually horizontally), plus and minus, designated (+) and (-) on the board, respectively. When plugging the wire into the hole on the board, it is fixed, and if the second wire connected inside the board is connected inside the board, there will be a contact between them. Macateboards are divided into collet, or the roaming, which we examined above and the boards that need to be soldered. In factory dumping fees, calculated under the soldering, insert the wire into the hole, pecks it with contact on the board. An example of such a fee next photo:
All compounds on such payments are carried out by flexible mounting wire, sweeping it to the contacts used. Such a wire can be as bare, and then in order to avoid closures, it is soldered along the entire length of the following to the contacts on the board, as we can see on the photo further:
Also connecting the contacts wire can be in isolation, and then it is soldered only to the contacts to connect. For example, as in the following picture:
Okatka Under the soldering office connection insulated wire
This is how the device looks like, from the part side, assembled on the batch:
The step of the holes in the board calculated under the soldering board (however, as the collet dealer) is approximately 2.5 mm, and corresponds to the foot of the legs in the chip made in the DIP case. Some craftsmen of radio amateurs, apparently of the principle make something similar to factory payments themselves, with their own hands:
In the manufacture of such a board, protecting the drawing with the help of a marker or, and pokes the places of future contacts. in conventional method, and after driving. Debugging fees for debugging device can be done more simple wayBy dividing the cutter on the plots a piece of foil textolite:
In Soviet times, when there were not factory baked plates on sale, and even foil textolite was not available to everyone, the radio amateurs were made of such dump trucks:
They made such a bold fee from the plywood of tin petals or a piece of plywood, subsequently listed, and the connecting wires were already soldered to these petals. Material prepared AKV.
When diagrams are soldered, you can do everything without additions. But then there is a pretty high probability that something can be closed. And then the scheme will not work. To eliminate this disadvantage and lead the results of the work in a more or less decent look, use such a simple and efficient invention like a dumping board. What does she represent? What kind of varieties exist?
Bread board
How to use this invention? To begin with, clarify the terminological component. Damage fee is a universal workpiece that is used to collect and simulate prototypes. electronic devices. They can be divided into two types:
- Those that are used.
- Those where soldering are not.
During the creation of prototypes of electronic devices, everyone has to meet with several problems:
- The bold fee must be designed from scratch, and then made. When an error assumes it will have to redo it.
- Create a single copy, as a rule, is not profitable.
- If the scheme is made on low integration chips and analog elements, then make it easier will be mounted mounting. But microprocessor devices will be very difficult to make microprocessor devices.
In the least advantageous position, novice radio amateurs: since they still do not have the skills of designing schemes, then they have to operate with the "present method". Therefore, at the moment there is a wide range of various dumping boards, where different short tracks were performed, and the person will only stay to connect the details to get the necessary circuit.
Varieties
Distinguish several types of dumping boards:
- Universal. There are only metallized holes that will be connected by the developer.
- For digital devices. They exist separate places where the chips can be placed. Also all the board conducted tires for power supply.
- Specialized. Created for various devicesthat should work on certain chips. As a rule, are very functional and worked.
Also, depending on how they are made, two types are distinguished:
- Chimunsky dummy. As the advantages of this species, the integrity and accuracy of execution are usually called (if we talk about industrial samples).
- Speeded dummy. The cheapness and the possibility of easy-to-change device are the main advantages of this species.
Mounting fees for mounting in the nest
Such blanks have thousands of holes that are connected with each other by metal stripes. The conclusions of microcircuits and radio components are inserted into the holes, and then connected with jumpers. Long rows of contacts that can be seen at the bottom, in the middle and at the top of the board are the power bus. They are used to connect numerous scheme points from the ground and the power source. Under each hole is the elastic contact of a special form, which provides high conductivity and durability of the compounds. The bold fee can be escaped. In such cases, the grooves are located on the side of the sides to connect several devices to one large.
Conclusion
The dumping fee significantly allows us to facilitate the work of the developer. It also increases the stability of the scheme, so do not break the device. It is impossible not to note the important role that the bold feet plays for people only begin to engage in the development of electronic devices, because many of these billets are produced already under the creation of certain devices. Therefore, when designing a popular scheme, it makes sense to search if there are already blanks under it, because if the answer is positive, it will significantly save time.
To establish and test home-made electronic devices, radio amateurs use so-called dumping fees. Applying a dumping board allows you to check, establish and test the scheme before the device is collected on the finished printed circuit board.
This avoids errors when designing, as well as quickly make changes to the scheme being developed and immediately check the result. It is clear that the dumping fee will definitely saves a bunch of time and is very useful in a radio amateur workshop.
Progress and electronics development also affected the dumping fees. Currently, you can, without any special problems, purchase an inconceptuous battle fee. What are the advantages of such an insane dump truck? The most important plus of the inconvenient circuit board is the lack of the soldering process when making the scheme. This circumstance significantly reduces the process of maketting and debugging devices. Collect the scheme on an insane circuit board can be literally in a couple of minutes!
How does the bewildered dumping board work?
The inconception makeboard consists of a plastic base in which there is a set of conductive contact connections. There are a lot of these contact connections. Depending on the design of the dumping board contact connectors Combined in strings, for example, 5 pieces. As a result, a five-pin connector is formed. Each of the connector allows you to connect conclusions to it. electronic components or conductive conductors with a diameter, as a rule, not more than 0.7 mm.
But, as they say, it is better to see once than hear a hundred times. This is the looks like an inside EIC-402. For mounting without soldering by 840 points. Thus, this dampboard contains 840 contact connections!
The base of the bold fee - ABS plastic. Contact connectors are made of phosphorous bronze and coated with nickel. Due to this, contact connectors (points) are designed for 50,000 connection cycles / disconnection. Contact connectors allow you to connect radio components and conductors with a diameter of 0.4 to 0.7 mm.
But it looks like a debug board for the microcontrollers of the PIC series, assembled on an inconvenient dummy.
As you can see, the beam-free dummy board allows you to install resistors, capacitors, chips, LEDs and indicators. Incredibly easy and convenient.
With the help of an invisible dump truck, the study of electronics turns into a fascinating process. Circuit diagrams are collected on a layout without excess work. Everything is so simple as if you were playing with the LEGO designer.
Depending on the "steepness" of the beam-free bobbin, it can be equipped with a set of connecting conductor (wires-jumper), additional connections, etc. Despite all the "buns", the main indicator of the quality of the invasive dummy is still the quality of contact connections and their quantity. Everything is clear here, the more contact points (connections), the more complex scheme can be mounted on such a board. The quality of the connector is also important, because from frequent use, the connectors may lose their elastic properties, and this will lead to poor contact quality.
Since the dummy board connectors allow you to connect the conductors with a diameter of no more than 0.4-0.7 mm, then the attempts to "squeeze" thick conclusions of parts can only lead to the damage of contact. In this case, to the conclusions of radio elements having a sufficiently large diameter, for example, as in powerful diodes, it is better to solder or wind the wire of a smaller diameter and then connect the element to the dumping board.
If it is planned to make a sufficiently complex scheme with a large number of items, the area of \u200b\u200ban invisible dump truck may not be enough. In this case, it is better to divide the scheme to blocks, each of which needs to be assembled on a separate dealer and then connect the blocks into a single device using connecting conductors. It is clear that in this case there will be an extra damp.
As a rule, a dialing board with a set of connecting conductors of different lengths (wires-jumper) is more expensive than ordinary beamboatics, which are not equipped with such conductors. But it does not matter. As a connecting conductors, you can use the usual wire in isolation.
For example, perfectly suitable for such purposes is very common and affordable wire KSVV 4x0.4This is used to mount the security and fire alarm. This wire has 4 veins, each of which is covered with isolation. The diameter of the copper core without taking into account the insulation is 0.4 mm. Isolation from such a wire is easily removed with nipples, and the copper wire is not covered with lacquer coating.
From one meter of such a cable, you can make a complete residual conductors of different lengths. By the way, in the photographs of the dummy card shown above, the KSVV wire was used to connect radio components.
The bold fee should be protected from dust. If the layout is not used for a long time, then dust is settled on its surface, which clogs the contact connectors. In the future, this will lead to a bad contact and the layer will have to be cleaned.
Chimunical dumping fees are not designed to work with a voltage of 220 volts! It is also worth understanding that makting and verification of work high flow schemes There may be an overhearance of contact connections on an uncerexious.
Shielding of the dumping board.
Preparation of an invoking dumping fee before work.
Before starting to master the diagram on a new inclosable dummy card, it will not be "ringing" contact connectors by multimeter. It is necessary in order to find out which points-connectors are interconnected.
The fact is that the points (connectors) on the dumping board are connected on the dumping board in a special way. For example, the EIC-402 loature dummy has 4 independent contact zones. Two on the edges - these are the power tires (plus " + "And minus" - "), They are labeled with a red and blue line along the contact points. All tire points are electrically connected to each other and are essentially one conductor but with a bunch of point-connector.
The central region is divided into two parts. In the middle, these two parts shares a kind of groove. In each part 64 lines of 5 point connector in each. These 5 dot connectors in the string are electrically connected. Thus, if you install, for example, a chip in the DIP-8 or DIP-18 housing in the center of the dummy board, then either of its output can be connected either 4 outputs of radio elements or 4 jumper connecting conductor.
Also, a power bus on both sides of the dump truck will also be available for connecting. It is quite difficult to explain this. Of course, it is better to see this live and plentyful macatetie. Here I assembled this scheme on an invoko board. This is the simplest debugging board for PIC series microcontrollers. It has a microcontroller PIC16F84 and the strapping elements: indicator, buttons, buzzer ...
Mounting fee for installation without soldering is convenient to use for a quick assembly of measuring circuits, for example, to check the IR receiver.
Such fees can be purchased not only on the radio rolls, but also buy on the Internet.
