Metal Backed PCBs
Due to the advantages associated with metal core pcbs, this market is growing rapidly. Their high thermal conductivity means the material thickness can be reduced which ensures cost savings.
In addition, these pcbs have excellent heat dissipation allowing the operating temperature of components placed on printed circuit board to be significantly reduced. This is highly practical as potential malfunction or damage can be avoided.
At Sourceman, we support clients in automotive, aerospace and industrial for all their IMS needs.
