Hi Aleli! The JSTD-002/003 committees have been extremely active in the evaluation of the wetting balance in terms of gauge reproducibility/repeatability as part of an effort to evaluate the wetting balance as an acceptable method for solderability testing. The wetting balance test is current categorized within the 002/003 specifications as "for evaluation only" test methodology as the investigation efforts are continuing. The wetting balance test method has recently undergone significant revision and both specifications allow the use the test method for product acceptance testing provided user and vender can agree on a set of pass/fail criteria. Please give me a call and we can discuss the detailed efforts of the 002/003 committee activities concerning the wetting balance.

Hello to all the people in this list. I hope you can help me. 1. Now that the direction the industry is taking is towards the development of packages with reduced lead widths (primarily because of the shrinking package size), is the "Dip and Look" method still the preferred test for Solderability Test? 2. I have asked around other assembly companies and those who purchased the Wetting Balance system told me that they are unable to qualify the machine because of "calibration problems" and never got to use it since it was purchased. Do we have somebody here who encountered similar problems? Was it ever resolved? How? If there are suppliers of various Solderability Testers here, kindly e-mail me privately ([log in to unmask]). Thanks a lot.
