LASER4DIY - Open-Source Laser Structuring for PCB Prototyping

Project description

Laser4DIY is a open-hardware machine for producing electronics boards by ablating copper with the use of a laser. It consists of several parts: a micro-chip based DPSS laser source, driver electronics for the pump laser diode, a cooling system including a 4-channel TEC-Controller, a low-profile, motorized XY table and a safety enclosure. These modules can be used not just in the Laser4DIY device, but also in other setups.
