Dear Frank Most PCB test labs such as Microtek can perform such testing. This will require you to fabricate test specimens and the handling will be critical so the test lab should give you special instructions on this. Regards C.B.

Or any testing lab can do this testing? This test is related to evaluate the clearness of the PCB or PCBA process based on IPC-TM-650, Test Number 2.6.3. 有谁知道Coupon Sampling Testing 的实验要求吗? 请帮忙提供。听说它是按照 IP C-TM-650中的 2.6.3 规定来的,主要是用来评定PCBA的清洁度。 Best Regards Frank Mar.02,2010 ______________________________________________________________________ This email has been scanned by the MessageLabs Email Security System.
