StencilQuick™ Lead-Free Solder Paste Rework Study

Technical Library | 2007-01-31 15:17:04.0

The goal of this project is to evaluate the reliability of lead-free BGA solder joints with a variety of different pad sizes using several different BGA rework methods. These methods included BGAs reworked with both flux only and solder paste attachment techniques and with or without the use of the BEST stay in place StencilQuick™. The daisy chained test boards were placed into a thermal test chamber and cycled between -25ºC to 125ºC over a 30 minute cycle with a 30 minute dwell on each end of the cycle. Each BGA on the board was wired and the continuity assessed during the 1000 cycles the test samples were in the chamber.


Oxide Thickness and Solderability Methodology to Determine Long Term Storage of BGAs and QFPs

Technical Library | 2014-10-16 16:39:12.0

Key points are: *Long-term storage of BGA & QFP products may be required due to: Fab and assembly factory transfers Product obsolescence requiring customers make lifetime/EOL purchases Providing extended service (10+ years) on vehicles Other program needs * Integrity of EOL products in terms of solderability needs to be verified.
