Sorry, I am jumping into this late - I'm a new user. Our company is looking to perform an evaluation for a new paste. We are looking at a 63/37 no clean - type 3 or 4. Our technology is currently at 0201s, .4mm pitch ICs & .5mm uBGAs. I have

We tested SAC305 in our selective solder machine and found the dross production made it an unnaceptable choice of alloy. Personaly, I cant imagine dross in a joint being a good thing but if it is a very small amount and does not occur very often, y

I have been through this before. At a med. device company they required every device that performed a measurement to be calibrated. O-scopes, calipers, 6-inch steel rules, etc. And thermocouples. While I can't see what difference it makes to the pr

I know what you mean. Saw this in systems where cooling was not done through the reflow nozzle (i.e. PACE). What happens is that as you run 1-2 profiles, the metal parts along the pathway of the hot air (before it comes out of the nozzle) act as he

What kind of parts are on the bottom? Small passives are very unlikely (won't unless other abnormal factors come into play) to fall off when reflowed a second time regardless of temperature differential. There is a simple weight/soldered surface ar

Thanks in part to help from the good people in this forum we've got our 1989 Fuji IP-1 working really great! We can run for hours without missing a beat (except to replace empty reels). Although I'm careful to lubricate as per the instructions the

Hey all, I just though I give you all a quick update. I managed to get the printer working. The problems were a combination of everything that was discussed here. When I adjusted the GS4 pot for the histogram, I turned the wrong one at first. This t

I am in the process of characterising a new vapour phase reflow system and am interested to learn if anyone out there has ever come across time/temperature datalogging equipment capable of being run through the entire process (including vacuum) along

Craig- Your point assumes most if not all of the problem lies in inferior equipment. I understand your point but I believe that an excellent process can overcome the fact that you don't have brand new and pristine equipment. As an example you can

No. It was CK who brought up AC at his home and erroneously said that having your AC on a lower setting used less power than having it turned off when you are not there. I'm saying with AC at home turn it off when you are not there and have it come
