We also had this problem and found similar results with the anti-backlash nuts binding. We went through the process of cleaning the lead screws and the nuts which resolved the problem for about 6 months only to have it return. We learned that the

Yes, your picture is correct. Regarding the dichroic mirrored prism assembly…in this application, a dichroic material is one which causes visible light to be split up into distinct beams of different wavelengths. The original meaning of dichroic, fro

Outside the MSD issues stated already (and I cannot provide a exact time not knowing multiple factors like Humidity levels, temps, exposure times, etc...) OSP might be the very worst finish to use in this scenario of side 1 / store on a shelf / side

I have a customer who is rather inexperienced, and asking us for a solution for them. They have a circuit board that's roughly two inches long by 1/2" wide or so, with component placements on one end of the board. The other end has a trace that I s

I'm sure they'd be open to acrylic, as it'll provide a nicely hardened finish for them once cured. The real question is would it be workable to do what they're asking. That is, thick enough to coat the board when we dip it in without all slopping o

Two things ... A friend in the contract coating business said: "... the board is not being baked out long enough, 30 min is certainly not long enough depending on how many layers this board is, as the vacuum (from the parylene process) is pulling t

Oh yeah, so we have a auger valve similar to that on one of our other machines that we use for dispensing SMT glue, and solder paste also. We have a conditioner that we flush it with at EOD when in use, then we just let it sit idle with the condition

Leaded HASL on small pads can be quite difficult to print on...the HASL tends to be domed rather than flat..and that can affect print quality...you really need a perfectly flat pcb pad to print paste on when you are assembling 0.5mm QFPs. If the pcb
