Hi Gaby, The IST test equipment is sold by PWB Solutions Inc. (Since I am in the process of relocating, all my references are packed up; you need to get address and phone number from the IPC_ ask for Bil Birch) and also they do testing as a service. Many of the good PWB manufacturers ( like Merix, CircoCraft) use IST, but certainly not all. Werner Engelmaier Engelmaier Associates, L.C.
