Abstract
A method of manufacturing a chip support board structure which includes the steps of forming a metal substrate structure, forming a photo resist pattern, etching the metal substrate structure to form a paddle, removing the photo resist pattern, pressing an insulation layer against the paddle, polishing the insulation layer, forming a circuit layer and forming a solder resist is disclosed. The metal substrate structure is formed by sandwiching a block layer with two metal substrate layers, multilayer. The metal substrate structure is etched under control to an effective depth such that each paddle thus formed has the same shape and depth. Therefore, the method of the present invention can be widely applied to the general mass production processes to effectively solve the problems in the prior arts due to depth differences, such offset, position mismatch and peeling off in the chip support board.
