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

We vote for: IPC-TM-650 2.3.25.1, solvent: 80�C, extract time: 60 minutes, hold time: 30 minutes or until room temperature. Listen, it really doesn't matter which method you decide to use. IPC-TM-650 2.3.25 is a process control method. It's more imp
