I presume the dongles you talk about are for an application called HLC from JUKI. The 2 different versions are for the later 2000 and 3300 and FX series the other key for the older 700 series. There is another way to solve your problem. AN applicatio

Does anyone have experience of using a stainless Fine Grain SMT stencil for the purposes of applying ink to bare PCB's? We are exploring the possibility of getting a stencil to apply a letter that reflects the revision to each of 25 PCB's in a panel.

I am curious if there is any benefit to using two different PCB paste layouts on one stencil. If I have a small PCB with a layout that doesn't take up much space on the stencil, would it be worth it to have both the secondary and primary side apertur

When we were selecting our AOI I made 3 test boards. 2 of them were "golden boards". These 2 had different shades of green solder mask as I had been told this could cause some issues. I did not encounter that during our selection. The 3rd board ha

Gyver: Lemme take a wack [if you�ll excuse the expression, given direction of the later discussion] at your questions. Q1. Will the baking of BGA or PCB cause more oxidation before the SMT process? A1. It certainly will not cause less oxidation,

Robert: Out of curiosity, by "BT" do you mean: � Bismaleimide triazine, the stuff used to increase the tg of resins used in some BGA interposers. � British Telecommunications plc, the guys with bad teeth. � BrookTree, the RAMDAC supplier, that�s par

I admit, 16 mil QFP printing is very challenging but if all your control factors (print speed, etc...) are setup correctly (through DOE) extremely high yields can be achieved and more importantly a repeatable and robust product will be manufactured.
