Abstract
The present invention relates to a manufacturing method of a printing circuit board. The manufacturing method mainly includes: forming one or more cylindrical micro-radiators by cutting a high conductive and electrical insulating substrate according to predetermined size; manufacturing one or more mounting holes in copper clad plates and prepregs; embedding the cylindrical micro-radiators into the mounting holes. The present invention combines the micro-radiator with high thermal conductivity and traditional stiffness printing circuit board. The printing circuit board with micro-radiators has the advantages of high thermal conductivity and stable heat transfer, and also has the advantages of routing flexibility and reliable electrical connections.
