Or you can use the Hot Air (Hakko) to remove that component and a tweezer to pull it. dont pull it just yet. If you see the solder melting then feel the component using the tweezer by wiggling it a bit and if you can wiggle it only then you can pull

Problems like these are not caused by bad feeder quality. As described in the solution finding, the pull off forces of the cover tape are just too high. Cause is the blistertape and not the a feeder. Have you ever tested if the pull of force of the

As I understand, you are wire bond gold wire to gold pad, where the substrate has good bond strength, but the die does not. If bond quality is good, and then drops off rapidly, then it's probably something to do with contamination within the system

OK guys, we got our Adipic acid. What is the preferred methode of applying it? a) Nozzle mounted, momentarily turn off wave and then brush? Or b)coat nozzle with the acid then mount it and turn wave on? By the way, we are using Indium flux WF-994

Hi Dave, Thanx for your reply. What is it in the process of manufacturing the capacitor that can go wrong until it can caused the chips to be chipped-off or cracks. I've encountered alot of this problem lately. First I thought it was our process t

Do some push / pull testing. Typically with black pad, you can flick the components right off the board. If you have this, the boards are about as reliable as a Yugo. If you get decent push / pull results, odds are you don't have black pad and you

This problem has become a real issue with the tacky silicon used in many LEDs. Cree has recomended that the pull off angle be changed for the cover film as mentioned by the previous commentor. With these new silicon LEDs they are recomending teflon o

AR Sounds like dirty chains... couple ways to check... Pull off the drive chain for the conveyor. Place a wrench on the (unload end) drive shaft and spin, if it is a bit tough.. dirty rails. Also look at load end of chains. The chain goes low and w

The only time i have seen this (5 years) has been from operators not allowing the magazines to shut off before pulling them out of their slot. Check the handles on the front of the magazines. If you see some dings on them there is your answer. Good l
