The hot air leveling process of PCB is to immerse the printed circuit board in molten solder, and then use hot air to blow off the excess solder on the surface and metalized holes to obtain a smooth, uniform, and bright solder coating, which has good solderability. The coating is completely free from exposed copper….
The working environment of the multilayer PCB will be subject to different external interferences. This interference on PCB Circuit Boards may be interference from the power supply, interference from the space electromagnetic field, and interference from the ground wire. So, what are the measures to suppress interference on the electronic board? 1. Filtering: A filter…
There are many differences between the flex and rigid board in the CAD design of rigid-flex PCB 1. Design requirements for flexible zone circuits. （1）Avoid sudden expansion or contraction of the line and adopt a tear shape between the thick and thin lines. （2）When the pad meets the electrical requirements, the maximum value should be…
In the production process of SMT small batch chip processing plants, some circuit boards or components need to be manually soldered for some reason. Soldering Problems in SMT chip processing is a very important part of the electronic processing and production process. If it is manual soldering, Only by achieving the same effect as the…
PCB Splicing not only involves the quality of the PCB board but also affects the cost of PCB production. How to make a reasonable and effective boarding under the premise of ensuring the quality of PCB circuit boards is a problem that PCB engineers and PCB manufacturers pay great attention to. How to make a…
We know that in High-density PCB design, seemingly simple holes often bring great negative effects to circuit board design. Therefore, in the design, we should try our best to do the following: 1. Considering both cost and signal quality, choose a reasonable hole size. For example, for the 6-10 layer memory module PCB design, the…
The Electronics Manufacturing Steps of PCBA Circuit Board include the following 11 main points 1. Solder Paste StencilingFirst and foremost, the PCB HERO applies a solder paste to the printed circuit board. In this process, you need to put solder paste on certain portions of the board. That portion holds different components. 2. Pick and…
PCB manufacturing has conventional requirements and unconventional requirements. The PCB circuit boards of conventional demand are large in quantity and affordable and are favored by customers. So, what are the general requirements for PCB manufacturing? 1. Meet: PCB processing technology requirements. 2. The surface treatment has a strong anti-oxidation ability. 3. It can directly point…
What is a Rigid-Flex PCB?, Rigid-flex printed circuit boards are boards that use a combination of flexible and rigid board technologies. a rigid-flex PCB is a combination of both rigid and flexible substrates. One or more flexible circuits are used to connect subcircuits on rigid PCBs. In the standard multilayer circuit board PCB design, we…
The PCB board is a complete device only after PCB processing and can be used in application electronic products. The PCBA process is a combination of the SMT process and the DIP process. Today, we will share with you the steps involved in PCBA Electronics Manufacturing by Shenzhen PCB manufacturers. 1. Single-sided flexible printed circuit…
