We had a V-Tek TM30 manual taping machine using heat seal top tape. Had very good results- with skilled operator - to supply taped components to our 2x Fuji IP2 machines - no tape cropping. Stefan's points are somewhat valid, but you can have a succe

I have about 200 PCB's from which a 20mil pitch QFP must be removed, cleaned and re-used (will place them back in trays for the P&P machine to place the parts on new boards). My intitial concern is: how can we remove the parts in an efficient manner?

I might be saying something that will get me laughed off of SMTnet forever, but when faced with a similar problem here's what I did. Since I was removing parts I didn't see why I would be concerned about all the things that go on in a good temperatu

I have soaked the chains in a 5 gallon bucket with wd40. It does a great job cleaning the chain. After they are done soaking i take an air gun outside and blow the chain off. I found that using a medium temp lubricant does not cause alot of buildup o

Knock off some balls and you may find it has a flat bottom to it were it has mechanically stuck to the solder resist usually seen under 60X magnification. Common with Liquid photoimageable resist (I know again) Best way to check resist cure is to pay

Mike, Right down all the settings you have for your machine (this may take a while). Also back up the programs you want to save. Now....if i can remember correctly.....when looking into the black computer box from the back of the machine...in your bo

ING, you had to nake it difficult didn't ya! It appears that all of your parameters are okay. When you state that "sometimes there is a residue" is it liquidous or dry? Is your spray fluxer an ultrasonic or a spray gun head? You may not be getting

Hello PMD Don't feel like that, we live with these MPM's. And we have over 10 years experience. Also never mess with the down stop on any MPM and you will be better off. Most of mpm's machines have a down stop of .0750 and it should never be cha

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
