Thanks for the info so far, but still need a number or a formula to calculate. The site you have point me to can support in a way, but if I want to release a design procedure to our editors, a number will be very helpful. One more issue is what can b

Hello all I have used a couple of types one of them only clamped on two sides and you used a wrench and screwed the bolt down till it was tight ( what is tight) and there was no fram at all around the stencil so people got cut. the second one we us

You mentioned that you changed the layout some, and this can be essential in this type of process. If the SMT parts and TH leads have inadequate spacing on the bottom side, shorts may be inevitable (someone else will have to advise what the recommen

I was flicking through the "Element14" (previously known as Farnell) BIG catalog (looking at the pictures) far superior to looking via internet. and found the closest to what you are after a five pin version. "Battery Interconnection System" Header,

We have not tried VectorGuard, so I cannot comment on that specific solution. However we have been using a Tecan Genesis system for several years and are very pleased with it. Unlike the DEK solution, the tensioning is entirely mechanical so there is

In a previous job we had DEK cut our stencils. If you are not already using the Vector-Guard system it is very nice. It saves $25 (or at least at that time it did) per stencil, but the really nice thing is the space savings. You can store several ste

We are using a custom made nozzle, designed for this particular LED. The dome of the LED is also custom made, the diameter of the lens at the base is 2.9mm while the substrate of the package is 3.3mm, so this gives about 0.2mm spacing between lens a

Are they all evenly spaced? If that first gold is orange and the black is spaced farther apart than the others then it could a polarity band or not really a band. Don't know why a resistor would have one. If that is the case then it is a 47K 5%. Whi
