ActiveCN103917052BHigh precisionLow costConductive material chemical/electrolytical removalLaser etchingOptoelectronics
The invention relates to a method for processing a circuit board by laser direct forming technology. Firstly, the conductive layer covered on the substrate material is thinned, and then the conductive layer is selectively and directly removed by laser after being processed by hole making and electroplating thickening process. Thus, a conductive pattern structure meeting design requirements is obtained. The steps are as follows: first, make a monitoring disk, that is, use a laser to photoetch and remove the conductive layer from the monitoring pattern area; then, use a micro-etching liquid to thin the material of the conductive layer until the micro-etching is thinned until it is at the monitoring disk pattern. When the substrate is exposed; finally, after drilling and metallizing the thinned substrate material and the conductive layer material, the conductive layer covered by the substrate material is removed by laser direct forming, leaving the required conductive layer. The invention solves the processing problem in the current technology that the conductive layer is too thick after hole formation and is not suitable for direct removal of the conductive layer by laser or mechanical methods, and at the same time broadens the application range of the laser photoetching method for processing PCBs.
