I'm not scary, just been doing this a looooong time. I've seen alot of things and I've seen a lot of good engineers get flushed for not playing the game right. Too bad some of us have to. And yes, you are right. Removing opportunities for rework

Just started doing BGA rework. After the removal of the "old" component and after site cleaning/component reballing I am ready to install the component on the PCB. It is recommended to apply flux or paste to the board/component. I would appreciate m

We agree with Russ and Ioan that rework does not cause black pad. It's caused during the board fabrication process. On the other hand, we think: * Mantis wants to reduce the amount of reworking of boards that fail due to a black pad problem. *

Hi CJ, if you need a rework station for any SMD's (fine pitch, BGA's, chips, SOT, ...), maybe you should also check ERSA that offers rework stations with computer controlled thermal profile (meaning you can apply a typical profile for each typical re

Hi Ahmad, I am using SRT 1100 for about 4 years. I like it but I am looking for something better. What ERSA Model you are using? Is it IR/PL 650A? I do BGA Reworks almost everyday. The most difficult Reworks I have had so far are a very small u

Hi, I think what you are describing is a half-etch QFN, which causes the 3 mil gap. In our process, we don't require solder to bridge this gap as it's internally connected to the bottom lead. I'm not sure if this is the question you're asking, but

I think this depends on what you are reporting as defects... I would place my inspection first, team up my Touch-up/Rework into one category. If for any reason I need to hit a joint after leaving my oven, that to me is classified as a defect and s
