If you use Entec 106, make sure that the PCB supplier has an in-line process. Dip tanks will cause major problems. Also the PCBS need to be thoroughly dried before packaging. If not, you will have solderability problems.

Our goal being to implement this on the circuit boards in the near future. I am looking for any and all information that anyone may have(I have a pile of articles 12" high) with use in production. I am especially interested in: What type of coating is on the board Number of heat excursions you have and does the coating live up to its published cycles Special handling procedures(operators) Board storage, time in production How you flux/profile/anything you did to get the topside fillet Use of nitrogen? Have you had solderability problems and how were they handled Do you specify board cleanliness, coating brand, thickness on the print and how is it verified. Thru-hole components scrap the inside of the barrel when inserted, any problems here with soldering Any special tricks done at the wavesolder Any and all information is appreciated Thanks Ed Holton [log in to unmask] *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * *************************************************************************** *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ***************************************************************************
