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.
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.
- Mill the board with a LPKF circuit board plotter.
- Apply special adhesive film to the surface of a milled PCB and drill the through-holes.
Applying the protective film
Drilling the board
- Apply the conductive polymer to the PCB to fill the through-holes, then use the vacuum table to remove the excess conductor.
Using the squeegee to apply the conductor
Flipping the board
- Remove the film cure the treated PCB in an oven for about thirty minutes.
