Flexible PCB supplier china ：What are Halogen Free PCB Boards?

A Printed Circuit Board devoid of the halogen elements is called Halogen free PCB . Halogen elements are Chlorine, Bromine, fluorine, iodine, and Astatine which are very fatal to life. For a PCB to be considered “Halogen-Free” it must have less than 900 ppm of chlorine or bromine and a total of less than 1500 ppm of Halogen materials.

Flexible PCB manufacturer： you really know single sided PCB ？

A Single Sided PCB that produced by Flexible PCB manufacturer is the most basic type of printed circuit board. It consists of only one conductive copper layer above the substrate.

PCB supplier china：What is Immersion Tin ？

Immersion Tin (ImSn) is a metallic coating of‘Tin’, which is deposited directly over the top copper layer of a PCB using an electroless chemical bath process.

What are PCB Stiffeners in PCB manufacturer China？

When working with flexible PCBs that in PCB manufacturer China there are times when we need certain parts of the flexible printed circuit board to be rigid. We do so by adding mechanical support to parts of the PCB. This mechanical support is called a PCB Stiffener.
