What is
 
  Normal process such as polymer PTH, carbon PTH, chrome PTH Technique has a reliability problem on low adhesion. However CERAMIC metalizing technique eliminate the problem.

  Effect
     Increase PTH reliability.
     CERAMIC PCB: Able to dip soldering.
     Cope with high thermal and high current.

  What is DCB?
 
  DCB or DBC PCB which is Direct Copper Bonded on a ceramic insulator with Al2O3(aluminum oxide: alumina) or AIN (aluminum nitride). Pure copper foil is attached by high temperature eutectic melting point with Al2o3 or AIN and with this firmly stick on the ceramic b/d.
