Here are a couple of things to look at. 1. Watch the machine run....and if it misses a part....make sure it doesnt blow out the next part being presented. Sometimes the air pressure is too high and the vacuum verify will blow the part out of the poc

EricR: Regarding "*** By the way, since we have used the Tin-Silver-Copper lead free solder there has been a strange liquid type chemical leek from the oven exhausted pipes." ... I don't know anything about your process, but the first thing I'd inve

In order to be able to do full prototype assembly, you will need to be able to mount and reflow a large number of different devices of differing technology. One part might be a simple QFP, another might be a .4mm pitch uBGA. If you are prototyping a

Thanks for the help. Ramp soak spike but due to the density of this assembly it's more like ramp spike. Yes, leaded. I'm getting similar results with or without the carrier. (I designed the carrier like swiss cheese, full of holes and scallops on

First, it's not a simple as thinking just about your electric meter. * Water heaters need to be DI proof, stainless or ceramic. * The longer that DI water is exposed to air, then closer it becomes like tap water. So, you need to be monitoring DI leve

I don't know your oven but I have dealt with high temperature ovens/furnaces before. These would be my thoughts. Change in the resistivity of the heating element due to aging. Blockage of air flow in the oven by buildup of soot/ debris in either th

We have two ZipaTec 460s Selective Solder Machines, one for Lead and one for Lead-Free. This morning we noticed the solder pot was covered in solder balls, and after asking the operator what they had run, the answer was "Nothing." The operator had al

If you have Flexhead nozzles you need to be careful that whatever solvent you use does not attack the gasket adhesive. I might try a couple of drops of a spray like WD-40 or LPS. Let it soak for a few minutes and blow it out with compressed air. Repe

I'm going to be acquiring an older Kirsten Jet machine in the near future, but am having a bit of trouble locating a source for appropriate wave oil / ADL via a domestic US source. Their current recommendation is a product from Strub in Switzerlan
