In-house system for solder resist mask application and legend printing
LPKF offers two processes for the professional surface finish of printed circuit boards: Solder resist with LPKF ProMask and assembly printing with LPKF ProLegend.
With LPKF CircuitPro and a standard laser printer, you can create a photo template with the desired layout on a transparent film.
Mix the solder resist from the pre-portioned lacquer and hardener. Apply the solder resist onto the structured circuit board using the enclosed roller. The PCB is then pre-dried in a hot-air oven for 10 minutes.
Position the template on the printed circuit board and place both in the exposer. Activate the exposure unit for 30 seconds. Remove the circuit board and remove the template.
Mix the developer bath with the developer powder and hot water. Dissolve the unexposed solder resist in the developer bath using a brush. The solder resist is then hardened and cleaned in a hot-air oven for 30 minutes. Finally, a pH conditioner in powder form neutralizes all chemical components for environmentally friendly disposal.
