From the idea to the finished circuit board – fast and precise implementation of two-layer through-hole SMD layouts in-house.

The IFW Dresden manufactures two-layer, through-hole plated printed circuit boards with structure widths up to 100 µm for prototypes and small series. Depending on the requirements, structuring is carried out either using precise milling or conventional wet-chemical methods with direct exposure or film processes. Chemical tin finishes and solder masking are just as possible as full through-hole plating. Our infrastructure covers the entire process – from layout processing to exposure, etching, and drilling to final processing – for fast, flexible, and precise implementation.
