We are considering alternative Board Finishes to our existing HASL process. The HASL effects opens on 25 and 20 mil packages after reflow and we know if the advantages of CuOSP and other alternatives. OUR Concern: Is there a shelf life and handlin

Temperature vs time is what soldering is all about. The faster you run your conveyor, the more heat will have to come from the pot for a given assembly. Example: You heat the board to 200F top side through the preheaters. Eutectic 63/37 melts at 361.

Our customers use OSP, HASL, immersion tin and immersion gold as board finishes. If I recommend a finish to the customer, it is one of the immersion finishes or OSP. Those finishes have the advantage of a flat surface to deposit paste. HASL has va

We agree with Wolfgang. Adding points along his line of reasoning: * Also consider placed component prescience. Sometimes, a mis-pick results in paste on the nozzle, which leads to the next component being stuck on the nozzle and not placed, which
