The uneven copper surface area on the circuit board will worsen the bending and warping of the board. The circuit boards are mostly multi-layer boards, and there will be vias between the layers. The vias are divided i...

The rigid-flex board has both a rigid layer and a flexible layer. It is a multilayer printed circuit board.  However, due to the mixed use of multiple materials and multiple manufacturing steps, the processing time of...

Immersion gold uses a chemical deposition method, which generates a layer of plating through a chemical oxidation-reduction reaction method. It is a kind of chemical nickel-gold layer deposition method, which can reac...

Pollutants are generated during the manufacturing process of printed circuit boards, including residues of flux and adhesives and other contaminants such as dust and debris during the manufacturing process. If the PCB...

There are the main features of the PCB using the gold-plated board. Why use Immersion Gold The crystal structure formed by immersion gold and gold board is different. Immersion gold will be golden yellow and yellower ...
