Common questions and answers 

  • 1. What is the thermal conductivity of regular MCPCB?

    Different metal base(copper or aluminum) and different copper thickness (eg. 1Oz, 2Oz & 3Oz) leads to thermal conductivity varying from 2.0W/m.K to 2.7W/m.K.

  • 2. Is double side MCPCB available?

    In order to satisfy applications in different field, Rayben is working on high performance double side MCPCB with single circuit layer, which is the ideal alternatives to dissipate the heat generated by high power PSUs and high output projects, etc.
