High-density interconnect (HDI) is one of the fastest-growing technologies in printed circuit board (PCB) design. Due to the more concentrated arrangement of smaller components, HDI board allow a h...

The common PCB plate medium used by PCB board manufacturer is FR4 material, and the dielectric constant of relative air is 4.2-4.7. This dielectric constant varies with temperature, and can vary as...

What is a halogen-free PCB? 1. According to the JPCA-ES-01-2003 standard: Copper clad laminates with chlorine (C1) and bromine (Br) content less than 0.09% Wt (weight ratio) are defined as halogen-...

With the development and construction of 5G communication, the electronic equipment industry has an increasing demand for high-frequency and high-speed PCBs. Due to different use environments, high...

PCB reflow hot plate is the process of remelting the pre-distributed paste-like solder on the printed board solder pads to achieve mechanical and electrical bonding between the solder ends or pins ...

ENIG plating process is a surface treatment process used in PCB manufacturing. Its full name is the ENIG electroplating process, which forms a metal protective layer by electroplating a mixture of ...

Copper-plated PCB board refers to a thin copper layer formed on the copper electrode plate of a glass fiber chip, used to protect circuits, improve conductivity, resist oxidation, and enhance appea...
