Problems solved by technology

However, the thermal conductivity of the prepared plastic products is poor, and the plastic parts may be deformed due to heat generation.
If the thermally conductive powder filler is simply mixed directly into the active powder, the effect of electroless plating will be affected due to the lack of laser activation performance of the thermally conductive powder filler, which may cause missing plating or no plating
