Hello Action_101, We are pretty much on the same wavelength as far as moving the cut and clinch and leaving the board stationary. It is the first I have heard about the cut and clinch being difficult to work on but you worked on them so your opinio

You're creating a new alloy on the surface of your board. The alloy will have a melting point determined by the constituent metals of the alloy. Your alloy consists of: * Lead-free HASL solderability protection on the board * Lead-free solder paste *

It sounds like a bit too much solder on the PWB, caused by too large a pad for the lead it will contain. In that case solder reduction is the way to move forward. What are the options there? 1. New stencil or stencils - (not desirable) 2. Increas

Damn near impossible. You need to see a real change in the difference between the 2 elements you are reading. So to give yourself any hope run 2 long traces one top one bottom up the length of the board. Then compare to 2 wriggly traces at one end (o

Ok, I have an issue that is somewhat uniform in it's recurrence in that it keeps showing up on the same location on the board. The problem area is a group of traces on the exposed side, that keeps having solder mask peel occur. As you can see in the

Ok so here is where I am with everything. I pulled the cylinder and cleaned it out. Didn't find anything out of the ordinary inside. I set everything back up and tested it. Still nothing. I went into the I/O map and tracked down that input, I then

Hi All, I have been looking in to some failures of PCB's in Assembly. After SMT the boards are stored for different periods of time in high humity environment (72% RH and 21.4 degrees Celsius) before being sent to Assembly to be handsoldered/put thr

Thanks for the response, Rob. I tried the MOT cards and the problem did not move. I swapped the MOTY with the MOTX, but the MOTX had a small board attached to it that I moved to the MOTY that I tried. Do you know if there is a way to test that small

Hi, Rebecca, Hmm...two x motors? I'm a couple of years removed from MyData's, but, I don't remember two x-motors. Might be something in the My12's that I didn't see in my older My9 (and certainly not in my TP9). As to the small board...unfortun

It could very well be the Safety Relay located inside the ELMO PSU (Bottom left in computer cabinet). I just had the same problems on 2 MY9's within 2 months apart. the Part cost around $700.00 from Mydata (Now Mycronic). These fail commonly with old
