Charliem, Thank you for the input. Following this logic, in case if there are no soldering issues, pad coverage and voiding levels are within acceptable limits and a gap between BTC and pad let us say 200um, this could be accepted, right? IPC-A-61

Hello, Acceptance Quality Levels vary from company to company and product to product. I would like to know what AQL's are being used in the different markets, (military, telecommunucations etc.). What is the standard level used? What

I'm currently trying to get a feel for what oxygen level I will need in my lead-free assembly process. Do I need to go with the pure vaporized liquid nitrogen, or can I get away with one of the other "on-demand" operations? All assistance gratefully

I normally handle the soldering issues for this facility but a question was asked of me -- What the H@## is this stuff and what is causing it? Was wondering of I could get some input from any Guru on plating issues. Need info ASAP!!!!!!!!!!!!!!!!!!!

I don't know what a "mass defect" is. Defects are within AQL [acceptable quality levels] or they aren't. I start at General Inspection Level 2 in the AQL Chart ANSI/ASQ STANDARD Z1.4-2006 and a sampling plan ANSI/ASQ Z1.4 Adjust the Level for Budge

Thanks Dave! What level of voiding is acceptable? Would you please let me know if there is an EIA or other industry standard detailing solder joint quality? I will begin researching the background information you provided. Thanks again for your kin

Do anyone of you know if are there any Standard (IPC, JEDEC, etc) telling how much can be the acceptable level of TIC (ugr/cm2 NaCl equivalent) allowed on surace of Connectors, Components,before to be assembled on PCB ? Many thanks Rgds GS

Grayman: How does a "solder wave optimizer" replace fax paper to indicate flux penetration of PTH?

Since you are using an Ionograph you need to use IPC-TM-650 method 2.3.25, static method. The test method is free on the IPC website. You'll need to get your customer to give you an acceptable cleanliness level to test to.
