Hi Lupo, Are you talking about laser trimming the current limiting resistors in front of the LEDs, whilst dynamically measuring their output to get set light levels? If so then you need a laser trimmer & a very good photodiode/comparator feedback l

I am very familliar with various lasers and cutting technologies. This is probably the only laser technology that has a chance to do what you are after on FR-4 G10, G11 etc and not burn. It's new ground for them and I'll bet the system is not tooled

Hi, there are many type of lasers and each have its own applications. Have you tried the short pulse laser? I was told that it will have very minimal heat dissipated on the surface. On the other hand, there is also a water assisted laser where the wa

For laser marking you don�t require as powerful lasers then for cutting. A 20 Watt laser diode does already a good job. Because of the safety requirements the laser operates in an enclosure, which means more $$$ if you want to use the laser in line
