Unlike filling the through holes with conductive or non-conductive materials first, the through holes are completely sealed with copper. However, due to the difficulty and high cost of production, this through-hole plug is no longer commonly used.
Excellent heat dissipation or transfer performance
Due to higher thermal conductivity and stronger current carrying capacity
100% prevention of solder leakage and dust/liquid entering through holes in SMT process
Very good stability and reliability
High cost
Imitation of via size and copper thickness
Low demand
