Printed Circuit Board Introduction PCB ( printed circuit board ) is a key component in the electronics industry and it is also a basic component. PCB carries all the components to be PCBA and then becomes the core of every electronic products. This article will give you a general idea about PCB, show the PCB composition and some main aspects.   What is PCB？   PCB（Printed circuit board）is...

PCB Surface Treatment PCB surface treatment mainly includes: OSP, HAL, lead-free HAL, immersion gold, immersion tin, immersion silver, hard gold plating, full board gold plating, gold fingers, nickel palladium gold. In general, the common FR4 PCB surface treatments are as follows: gold plating (electroplating gold, immersion gold), immersion tin, OSP, HAL (leaded and lead-free). Different surface ...

Rigid PCB Manufacturing Process Flow 1. Cutting Cutting is the process of cutting the copper clad laminate into pieces that can be reprocessed in the production process line. (1) Unit: Unit refers to a single small board designed by PCB design engineers. (2) Set: Set refers to the unity formed by putting together multiple Units for reasons such as improving production efficiency and facilitating p...

Solder Mask Both sides of the PCB are copper layers. In PCB production, the final copper layer is a smooth and unprotected surface. Although the chemical properties of copper are not as active as aluminum, iron, magnesium, etc., pure copper is easily oxidized when there’s water and oxygen. Because of the presence of oxygen and water vapor in the air, the surface of the pure copper will oxidize ver...

Multilayer Printed Circuit Board The manufacturing method of multi-layer circuit boards, generally to make the inner layer pattern plating first, and then make the single-sided or double-sided substrate by printing and etching, and incorporate it into the specified layer, and then heat, press and glue it, and then other produce process is same as the production of double layer panel. In terms of p...

Rigid PCB is for holding electronic components and connect them together electrically. It consists of different resistors, capacitors, active circuits which are held together through electricity. The type of rigid PCBs are made up of different layer count.Different layer count can fulfill different electronic purposes.This is a quick overview of the different rigid PCB type advantages and disadvan...

A halogen free PCB is a printed circuit board with limited halogen elements. The main halogen elements that are fatal to life are chlorine, fluorine, bromine, astatine, and iodine. A halogen free PCB has less than 900 ppm of bromine or chlorine. Also, the board has less than 1500 ppm of halogen materials.But Chlorine and bromine have many benefits. Chlorine is a flame-retardant that protects the c...

PCB means printed circuit board and is an important part of electronic products. The quality of PCB is related to whether electronic products can work normally and reliably for a long time. Improving the quality of PCBs is a very important part. Is your method of testing PCBs manual or automatic? PCB board inspection, is manual inspection, or automatic inspection? Manual visual inspection: Using a...
