Hi Guys, There are techniques to do rework that involve molecular surgery even when selective, ablation and piles of localized techniques exist yet the cost is far too high and scrapping is mostly a best cost manufacturing alternative. At the cost o

I am looking for a fool-proof way to have operators measure PCB's out of the depaneler to ensure that the tolerances for the outside edges are being met. Probably a spot check system to make sure the process is in tolerance. So far building a "GO"

So sorry sir Fastec, but I am Mumtaz, not Guru. Call me a troll, but I have been a part of pcb assembly since it's inception. I speak from experience but also am eager to accept new ideas. Yes, I know the Guru may be playing us as fools and his pr

"Oh. [Howabout if I smack you?]" Like I ever said anything 'bout strings. Sheesh. I'm gonna save this one for future reference. Oughta take a week or two to figure out whether yer trying to make a fool of me or not. ;) Criminy. And I was think

Hi, Does anyone know if it's possible to place BGA's with pitch 0.5mm and ball diameter 0.25mm on a siemens F3. the manual says that smallest pitch on BGA's is 0.56mm. Siemens won't commit a yes or no, as you'd expect, but i'd have thought it w

Hi, How come so many good threads get off track because of this Guru fool. To get back on track, we have been running SN100C in our pot for a few weeks now, and it's incredible, and working really well. Glad I listened to the advise of people on th

We have the same situation here. But generally it is the customer gives us a 1-up Gerber drawing and we need a multi-up or some form of breakaway to make the product. The way we achieve this is thru a Word document we call PCB Guidelines. We attac

Sure you can. But I don't have the time, money or resourses to do this. I do not have the luxery of only getting SnPb parts. Wish I did, but I don't. As for temp specs, I know the specs on all my parts. We profile our ovens every month. We can

My pick and place machines are 10+ years old so I might be in the crappy department. I wasn't looking for a complete fool proof system, I am looking for aoi on a tiny budget that covers majority of scenarios. We will have to be mindful of solder sl

It sounds like the process is very labor intensive, and all the verification is done after the parts are soldered. Assuming you are hand placing the components: 1 - Contact Systems semi-automatic placement machine. It show polarity when placing, so
