Abstract

A high-performance UV-DPSS (Diode Pumped Solid State) laser drilling system (wavelength 355nm) for PWB's, which can drill a less than 50micrometers diameter via-hole, has been developed. This system has two main features as follows: 1. A vua-hole without smear is possible to be drilled for PWB's with the optimized irradiation conditions of UV laser. 2. High throughput was realized by using a high power UV-DPSS laser and a developed high-speed control method of galvanometric scanning. This paper describes the outline of the developed UV-DPSS laser drilling system. This system has the advantages which are required small via-holes formation less than 50micrometers in diameter, compares with a conventional CO₂ laser system currently.
