Basically, it's a tilting problem of certain devices. Usually with axial by-pass caps tilting, which pulls the lead up through it's mounting hole. Other problems with components with leads cut to lenght to eliminate post-wave trimming. All suggestion

Hi, Yes, it was quite funny, and everyone thought I was nuts, but it was something worth trying. It's often the weirdest ideas that work. The full tube was ok, but the half full one generated the plasma. That scared the hell out of us when it lit up

Is anyone using/tried this product/process in production? If so what advantages/disadvantages have you discovered? Whats the pricing like compared to standard PCBs? We run very high mix of products on the same line and am curious as to whether it is

I recently saw a brief presentation on selective cleaning using Co2. In basic terms a fine jet of Co2 is blasted onto the desired area of the PCB removing the contamination and supposedly causing no damage to PCB or components. I think it's quite a n

Grant is right, also for us was the easiest solution to us custom pallets. But you should also try to tweak preheat zones settings. The flux manufacturer should give you some basic temperatures where the flux gets activated. Also it is worth to make

Russ is correct, but you may have variations between board density types also. Some ovens may be able to handle low density boards with no spacing, but need a zone's worth of spacing for high density boards. Other ovens don't need any spacing for a

Worn out is all relative. If the machine is in a factory on a dirt floor with no air-conditioning.....it could be "worn out" after 1000 hrs. but then again....if it is in a well kept building with the proper maintenence........10000 hrs could be fine

We not sure what your supplier means either. So, maybe it's worth a follow-up call. One possibility is: The HASL could be lead-free as easily as it could be SnPb. You probably need to think about how you're going to change your reflow recipe to in

I'm confused. Aren't Fuji nozzles like $20 each? Why bother? I would hope you understand that a nozzle not properly repaired could cause $50 worth of rework in about a minute after you installed it. Stepping over dimes to pick up pennies comes to min

Hi Rob, Thank you very much for your comments. I appreciate that. Have you heard anyone use these pick and place machines? Their price is reasonable with our budget, but I don't know if it is worth to start. If anyone by any chance has used these mac
