Hi Wolfgang - Karl Wengenroth presented some data concerning OSP finishes and ICT issues at the IPC Surface Finish conference. Get a copy of his paper: "OSP Technologies: Meeting PWB Assembly Requirements", page 103-113, IPC Summit On PWB Surface Finishes and Solderability Conference Proceedings, September 1997. Karl presented some data on three different probe configurations (bullet, crown, chisel) and the information may be of help. Good Luck.

How can I help my customer with this ? I have heard about "Twister" testpins, increasing contacting force, tightly controlling initial thickness of the coating itself etc. What is your experience, What works in real life ?
