Can someone clarify whether IPC-TM-650 Test Method 2.6.27 (Thermal Stress, Convection Reflow Assembly Simultation) is required for all bare board fabricators? Or is this test method optional, depending on the type or class of boards being fabricated

Any recommendations? Looking for someone that's familiar (even intimate) with the IPC-TM-650 stuff.

TM-650 specifies a 50mm (2in) length of tape to be used for the test. What about areas that are smaller than 50mm? For example component pads surrounded by open areas are much smaller than that as are vias. If they pull off using the tape test would

your comments will be appreciated, please; IC tests have been performed on two kind of Raw PCBs (HASL) samples by adopting three different methods : First Sample (supllier A) - Omegameter 600 SMT, solvent=40�C: extratcing time 10 min result = 0.2

Don't sound proper. There is no specification. Pad peel strength test methods are: * IPC-TM-650, Method 2.4.21 for multiple solderings * IPC-TM-650, Method 2.4.8 for copper peel with a Instron machine. Typical requirement for Cu is: 6 lbf/in [1

It sounds like your board is "dome shaped", some call it "cupped". If so, this is more of a twist than a bow. Before moving on, if we receive a board that is so torqued that we can't figure-out how to measure it, we reject it. Go back to your TM-
