The PCBA processing, automatic optical inspection is usually

In PCBA processing, automatic optical inspection is usually set at the last step of the SMT production line, and it is necessary to detect the defects of the product after the completion of the SMT processing​ process.

The meaning of silk screen letters on the PCB board

R107, C118, Q102, D202 and other numbers are often seen on the PCB board. In general, the first letter identifies the device category, such as R for resistor, C for capacitor, D for diode, Q for transistor, etc.

What should I do when I encounter bad welded components in PCBA processing services?

Poorly welded electronic components. In the face of this situation, we generally remove poorly welded electronic components without damaging the PCB board.

Explain The Process Of Mobile Power PCBA Circuit Board Proofing

Pcb circuit board proofing: pcb circuit board proofing refers to the production of a small part of the product as a sample before the start of mass production, so that it can be better completed, and the perfect combination of mass production circuit boar

PCB Circuit Board Open, Short Circuit Causes And Improvement Methods

Designers using this approach can focus on masking the microstrip length of the copper foil in order to obtain good performance for signal integrity. For systems that use dense connectors in the communication structure, the designer can use a PCB as the t

PCB circuit board copper foil basic knowledge

PCB circuit board welding technology

As a power supply product, PCB circuit boards can be seen everywhere in life. This requires manufacturers to strictly put the quality in production, understand all the failure of the product, deal with it early, and reduce economic losses.

Talk about the cleaning technology of PCB circuit board

Do you know PCB cleaning technology? Here are some tips to share.

Analysis of etching technology of PCB outer circuit board

Further said, sulfuric acid-hydrogen peroxide, can not be used for lead tin corrosion resistance layer etching, and this process is not the main method in the production of PCB outer layer, so most people rarely ask.
