Good afternoon The ISI I was mentioning is interconnections solutions which is a division of Molex. a few years back we ran into a component end of life situation but had thousands of very high dollar bare boards in stock. the package was a BGA and w

The boards were just a little larger than a SOT8. IIRC we had a pizza slicer type depanelizer and it wasn't too bad. We just did enough to populate the bare PCBs we had. Where I am now a customer has us put a QFP and a few other parts on a SOW28 f

We used to empty the tank on Friday and let the stone basically dry out over the weekend. That was before I got involved with it. We were constantly replacing stones. Now, we empty the flux Monday morning and replenish with new. That way the stone

I have a used MyData My9 machine that I've picked up recently and it has a problem with initializing that I can't figure out. It just gives an error stating "no z indicator value at all". I've replaced the flex board with the force sensors but that d

Hi, We are producing a board that contains an RN4678 bluetooth module, and an STLINK-V3MODS module, both of which are castellated modules. I am constantly having issues with the modules being soldered to the PCB incorrectly. It seems that the RN4678

Possibly, yeah. Or the wrong sized nozzle ( or chipped or blocked ) We have problems occasionally with larger components and vacuum levels. If the component has a makers 'circular void' on the pick up surface then the actual pick coordinates have to

The problem is that.. 1) it always drops at the same location and the vacuum led shows that machine indeed turns the vacuum off ! 2) the same nozzle picks up much heavier components from other feeders without problems 3) the MTU component - i turn

Hello all, we use a reflow oven from Rehm in our SMT production. At the moment we solder under nitrogen atmosphere (approx. 500ppm). Now we want to reduce the nitrogen consumption (costs etc.). What consequences can occur here? Especially on the s

I'm not familiar with the machine, but isn't a KE760L an old slow "single head, single gantry" two spindle machine? Any speedup from simultaneous picking would not necessarily be that much of an improvement. Setup as you described is the way I would

I'll answer the easy part. If you put low temperature trays in the oven at 120C, they will warp and partially melt. I have seen it more often with reels of LEDs. Someone is told to bake them before use so the put them in the batch oven and the next
