Revolutionary technology to produce plated through-holes, which does not require a plating tank or potentially hazardous processing chemicals.


The LPKF ProConduct® through-hole conductivity system creates new technology for producing conductive through-holes without chemical electroplating tanks or potentially hazardous chemical processing.

The LPKF ProConduct® system is an ideal solution for many in-house rapid PCB prototyping environments. ProConduct® is perfect for low volume production, laboratories or shops where chemical electroplating is impractical, or any circumstance requiring an economical through-hole conductivity solution. Thanks to a parallel process even boards with high hole count are possible.

Easy to handle

LPKF ProConduct® uses a specially-developed conductive polymer to quickly and easily plate vias in just a few minutes. This four-stop easy-to-learn process lends itself well to parallel processing and results in smoothly plated through-holes in a fraction of the time and cost of chemical electroplating.

Perfect Results

The LPKF ProConduct® system plates vias as small as 0.4mm (15mil) up to an aspect ratio of 1:4. Smaller holes are possible under special conditions. The basic process requires only a few minutes for double-sided and even multilayer boards. The electrical resistance of LPKF ProConduct® results in extremely low – approximately 19.2 mΩ, depending on the material thickness.

Key to in-house work

When combined with LPKF ProtoMat circuit board plotter, the LPKF ProConduct® system becomes a key component to an in-house rapid PCB prototyping solution, featuring security, flexibility, and speed.

  1. Mill the board with a LPKF circuit board plotter.

  2. Apply special adhesive film to the surface of a milled PCB and drill the through-holes.
