We had a solder joint problem in gold plated PLCC68 ic. We do double sided reflow process with Cookson OL107F paste. First we do top with paste and second with glue process.The solder joint shape and wetting looked normal.In the process of testing

Yes, using an illuminated magnifing glass helps. How well your board fixuring is on the table will effect print alignment on other boards loaded. 0.5mm & 0.4mm will require very good fixuring, like you can get with tooling pins if the board has non-p

I know nothing about Xbox specific rework, but have a lot of experience with PCB repairs. "...maybe think its a bad idea now not knowing what im doing" Don't get discouraged, it's a learning process. If it was that easy everyone would be doing it.
