and also that most connector/PTH component vendors test their components with immersion temperatures of around 260 degc & they do not preheat the components, so it does not mimic the heat in a typical wave soldering operation

So at incoming inspection, what are the results for your "dip & look" solderability testing [IPC/JEDEC J-STD-002A] of the specific problem component?

So why are you telling us about the solder bar? What is the flux? that is what you need to change, you have a rosin based flux it sounds like. you can change probes in test fixtures or change flux chemistries. Russ

The standard Metronelec Menisco ST 60 can not run a dip and look test for PTH parts. It is an optional feature on that machine.

We bought a Apollo Seiko robot. this, from several test, was way out the best for our production. we use Ichikawa leadfree solderwire, this was the best result with this robot regards bart

since 1999 we use Heraeus PD944, in time we tested Loctite also but had some issues with it - or with our machine specialist :)) we dispense with Fuji CP (2 , 3 & 4) it only creates problems when its on the solder pads ;-) best wishes

One of our customers does a drop test. They hold the final unit five feet above a concrete floor and drop it.

"...but it would also be testing if they had enough mechanical strength to hold the components on." Only if you take the time to observe the results. :) Your point is well taken, but these guys were only interested in seeing if any failure modes pro

"Their third attempt was a report that Process Engineering was being resistive and skewing the tests." Thanks for the early a.m. laugh. I needed it.
