In the thick copper plating process of thick copper PCB, the process parameters must be monitored frequently, which often causes unnecessary losses due to subjective and objective reasons.

The difference between HDI PCB browning and blackening has the following two major points: 1. The similarities between HDI PCB browning and blackening. 2. The difference between HDI PCB browning and blackening.

We need to pay attention to the following five things when we manufacture thick copper PCB.

The outstanding requirements of PCB power supply are high reliability requirements and high plating uniformity.

When making imposition, you can easily separate multiple boards to avoid damage to the circuit board during the separation. Determine which type of board to use according to the shape of a single type of your imposition. PCB imposition methods mainly include V-CUT, punching, and stamp hole.

The PCB power supply uses high-quality imported IGBTs as the main power devices, and ultra-microcrystalline (also known as nanocrystalline) soft magnetic alloy materials as the main transformer core. The main control system adopts multi-loop control technology, and the structure adopts anti-salt spr......
