The activation tank liquid has no precipitation sludge, and the tank liquid life is up to 100 square meters/liter

There is no palladium residue on the plate surface after copper sinking

The resin and glass fiber absorb palladium in the hole thin and uniformly, which reduces the probability of gold on the NPTH hole of the predated nickel gold surface treatment process

The reaction time of a single tank is short, and the one-time equipment investment cost is low

The copper sediment layer has low stress, and the copper plating of the plate is resistant to thermal shock under the condition of 288°C*10S*8/10 times, which reduces the risk of cracking at the bottom of the blind hole and inline ICD through hole

Process capability advantages

A. Through Hole AR Max: 20:1

B. Blind via AR Max: 1.5:1

c. Plate thickness: 0.05~6.0mm
