PCB Laser Etching and Pocketing in a Single Step
Using a test sample, we have investigated how a wide variety of materials behave when different lasers are used to create 'blind openings'. However, milling of pockets is an initially obvious solution, but limiting is the fact that the diameter cannot be smaller than the smallest tool. For HDI PCBs, for example, a laser is therefore the ideal tool for producing 'blind openings' with extreme precision in all dimensions.
