PCBA Tech - PCBA proofing process and tools needed for SMT proofing

1. What should the PCBA proofing process look like?

PCBA proofing is a small batch of SMT placement for the design of a new product. The trial production verification test action can ensure that the product design meets the expected design requirements. PCBA proofing is generally divided into two parts, procurement and production. Today, I will introduce to you what the PCBA proofing process is.

1. Propose PCBA proofing requirements

Users place orders for electronics manufacturers according to specific actual requirements, and provide specific PCBA proofing requirements. The electronics factory evaluates its own capabilities and decides whether to accept the order. After the two parties reach an agreement, they will decide on the details of the production.

2, submit information

After the user decides to place an order, he must provide the Gerber files, PCB electronic files, BOM lists and coordinate files needed for PCBA proofing production to the electronic manufacturers, who will produce them according to relevant materials.

3, raw material procurement

Electronic manufacturers will purchase raw materials from designated suppliers based on the BOM list and PCB documents provided by the user.

4. Inspect incoming materials

For all raw materials needed for production, strict quality inspection of incoming materials must be carried out to ensure production quality and quality before production.

5, PCBA production

After all the work is ready, the components and PCB circuit boards are submitted to the DIP and SMT production lines for placement and soldering production. In this process, there will be strict furnace temperature control to ensure the quality of production.

6, PCBA test

After the end of production, the electronics manufacturer conducts strict PCBA tests according to the PCBA test plan provided by the user, including: FCT and ICT tests, so as to ensure the smoothness of the circuit and the fullness of the solder joints to ensure that the PCB board can be delivered to the user normally.

7, after-sales packaging

After the PCB board is made, it must be packaged for protection to prevent damage.

The above is an introduction to the steps of the printed circuit board proofing process. What is the PCBA proofing process? Through the above points, everyone has an understanding. It can be seen that the PCBA proofing process is a series of standardized steps, which can ensure the efficient operation of production. If the user has any problems after receiving the proofing board, You can directly find the electronics manufacturer to rework and repair

2. What tools are needed for SMT quick proofing?

SMT rapid proofing is the experimental production before the rapid mass production of products. The process of small batch trial production in the factory is a necessary step before entering mass production. The key to SMT fast proofing is to have appropriate tools. I will introduce it to you today.

1, soldering iron. The soldering iron here is the sharper one. The radius of the tip is within one millimeter, and the tip of the soldering iron must have a long service life. It is best to prepare two soldering irons, and use them for parts removal. It is strongly recommended that unskilled friends prepare two soldering irons.

2, fine solder wire. Need 0.3mm -0.5mm, do not use thick, because it is not easy to control the amount of tin. The traditional solder sucker is useless, as long as it is sucked with a braid.

3. Tweezers. Tweezers are used for electronic production. SMT quick proofing should also use a sharper one, and it must be stainless steel. This is because other parts may be magnetic, and the chip components are relatively light. If the tweezers are magnetic, It will be sucked up and cannot get down, which is very bad.

4. Magnifying glass. It is necessary to use the one with a seat and a ring lamp, and cannot be replaced by a hand-held one, because sometimes it is necessary to operate with both hands under a magnifying glass. The magnification of the magnifying glass should be more than five times, preferably ten times, but ten times is not easy to find, and the field of view will be smaller, and the field of view will be more expensive.

What are the tools needed for SMT quick proofing? Through the above content, we know that for SMT quick proofing, soldering iron, tweezers, fine solder wire, magnifying glass, etc. are needed. In addition, a hot air gun is also needed, which is used to remove multiple feet. The tool for SMD components can also be used for soldering, and the temperature of the hot air blown out is sufficient to melt the solder.
