A big customer for controller cards is complaining about the quality of the soldering on our PCBs. The photographs they sent were very unreasonable, pointing out minor defects such as tiny (tiny as in smaller than the point of a pin) drips of solder

Looks like you have a carbon black process that isn't quite plating to completion, pin prick size holes have remained in the plating. When dipped in an etchant (ie any acid or H2O) the holes grow and they leak carbon. This may be more of a problem th

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

I have a 208 pin QFP that due to manufacture obsolescence I have to get them form the broker market. I've had several issues with the parts including; bent leads, leads that don't take solder very well, co-planarity problems, and DOA fallout after a

Let me start off by saying that although we pot a decent variety of products, we have never been asked to do something like this, so this is not based on personal experience. This is just my gut talking here. I suppose you could use some sort of ca

There are several way to tech this. I used this machines some time ago and maybe I am rusty, but you can try two ways that I can think of: -use IC package with 4 leads from one side and 1 big from the other. You can play here a lot, for example you c

The numeric display number should be higher but only when all 7 spindles are moved down slightly from the full up position. The 7 spindles retract up to the Stop Bar. Each spindle assembly has a tapered hole thru it. This hole is in the block with t

Not sure what kind of humidifier you are looking at but here's my experience: We have 4 humidifiers. All are ultrasonic supplied with DI water. They work well but... UT humidifiers will create a foggy white residue that will stick to things in cl

Hi Larry, Picture a old lady with a set of knitting needles with leads attached to them, pressing the needles into different points of the PCB (pads, test points or component leads) and measuring resistance, inductance, waveforms etc between these p
