    Rigid PCB Manufacturing Process Flow Oct 26, 2021
    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...

    Why are most PCB board green? Nov 04, 2021
    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 Nov 22, 2021
    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 Printed Circuit Board Type Jan 19, 2022
    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...
  • Halogen Free PCB
    Halogen Free PCB May 11, 2022
    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...
