interesting, not at all what we were told so yes lot's of contradictions comming from them, I have to say personally I've not beein impressed with there technical service of late, are they getting complacent I ask? it's strange they say it'll cause

Purpose. This describes setting-up a wave soldering system set-up for a new assembly design or checking a wave solder machine operation with a test board. Applicability. To be used for new design printed circuit assembles and during machine accept

Differences between solder paste alloy SAC305 and SAC405.

"For the lead free soldering of electronic assemblies, the inclusion of silver in the alloy results in better wetting compared to non-silver containing alloys and also allows for a broader process window. Silver also improves joint reliab

| Recently, there has been an upsurge in the Pin Hole/Blow Hole problem in our wave soldering process. We are baking the PCBs for 2 Hrs. at 125 degree C. The Wave Soldering profile seems to be O.K. Still the problem is persistent. Can somebody hel

Lead-free and Leaded solder in the same reflow

At my last employer, we ran a number of tests to make a "Hybrid" profile work (same profile Joe lists) . It worked great for everything but BGAs. The problem (6 months ago) was using parts not rated for lead free reflow temps. As the market fills wit

No solder and solder bridge after Wave solder machine

Electronics Forum | Thu Nov 17 21:46:48 EST 2005 | C. Kolokoy

With DIP type components, a sub-par fluxing method (foaming a no-clean), and a chip wave where one is not needed are formulas for bridging and insufficient wetting. If you have SMD's on the wave solder side of the board greater than 0603, and no SOT

"Gap" in completed solder joint between lead and pad

Electronics Forum | Thu Nov 30 16:10:05 EST 2006 | Hussman

Wow, why all the anger? This gap you guys are talking about is measured as "G" in IPC/EIA J-STD-001 (Chunks was there, but she failed to read the fine print). And almost all parts that measure G follow Note 3 which states "Properly wetted fillet s
