The play of the tape is quite significant as I mentioned in an earlier thread. Tape width can vary between 8.1 +/- 0.2mm. Demos on 0201's are most likely done with 8.1 +/- 0.05mm tape. I guess you are referring to the cover tape pull, which can dispo

Sr. Tech, when you say you have never had a problem, what exactly does that mean? How do you know you have never had a problem directly associated with your solder process? Do you actively measure your defect levels? How do you maintain traceabili

Hi, follow up, Thanks to everyone that responded. We finished the build, the sun burst thru the clouds and the birds sang. Well that was a slight exageration. Sorry for lack of detail on the original post, I was frazzled. Since the 0201's were p

What is the recommanded profile for board which consist of 0402 & 0201 comps. to reduce the effect of tomb-stone. Slow ramp rate ? how slow is considered as slow. Soak time 60 or 120 C,at which end should I stick to? what is the best time before reac

Ken, With all due respect: Surface mount is surface mount. Whether you are placing 0201's, or PLCC84's the basic concept is the same. So I would surely hope that for the most part my process is transferable. I guess I was too broad when I said "we n

I have worked with Epoxy Technology in the past with silver epoxy. Just to fill you in on what I have been doing with this project in the past. I was using a silver epoxy for my 0201s. I then over molded with an epoxy with a dam and fill. Then th

Dave - I agree that the U shape for QFP's sounds a bit whacked, for the reasons you state. It may work OK for larger pitchs but then again there are a myriad of fixes that work before resorting to U shapes. With the U shape removing paste from under

I am having a common problem, justifying capitol expenses. We are currently using 0402's and BGA's and CGA's with 1MM centers. Our current equipment is horrible, we have a hand operated screen printer machine (No vision system) and we are placing all

Look into the Juki KE-2060E machine. I have been extremely pleased with this machine. It will hold 80-8mm feeders, place 0201 (0603-metric) up to 74mm square ICs and BGA, 150mm long connectors. Up to 25mm tall components. It can handle up to 30 t
