Photolithography is a key process in the production of printed circuit boards (PCBs). Gatema PCB has fully digitized the entire exposure process. For dry resist and solder mask, we use Schmoll MDI (micro-mirror-imaging) machines. Their advantages are versatility, higher precision, and the ability for individual marking.
Using MDI (Micromirror Digital Imaging), we are able to create the circuit board pattern directly on the dry resist without the use of a film mask. The radiation source is LEDs, which emit wavelengths of 365, 375, 395, and 405 nm. By selecting the appropriate wavelengths, it is possible to set optimal parameters for pattern creation not only for resist but also for the solder mask. At Gatema PCB, we have multiple MDI machines.
A replacement for the traditional screen printing method. This technology allows for direct printing onto the surface of the PCB using inkjet heads. The minimum font thickness is 130 µm.
Horizon M1 is a semi-automatic screen printing machine with horizontal lifting of the work table. The device is specifically designed for printing on PCBs.
The purpose of lamination is to apply the photoresist flawlessly onto the surface of the PCB. The Mach 610i features automatic panel detection and is also designed for laminating flexible materials.
