Hi folks, Lately I am also having problem with BGA ball problem. We are finding more and more on X-ray analysis and is very expensive to replace. I know for sure that we could rework on CCGA but there is no certified process in industry as we speak

Using convection type reflow we observed following problem: One ball of a 313-PBGA appears to be dewetting. This happens randomly, i.e. no specific ball location, failure rate is rather low (3-4%), but since there are 12 PBGAs on one board the failu

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

Interesting. We are also facing this problem due to; once in a while a matrix tray is mishandled by the operators and as a result those very, very expensive components falls to the floor and the columns got bent. We manage somethime to "straighten th

Hi I did a reflow on an HP laptop a while back- it was a DV6000 series. The original problem was the internet stopped working- turns out the south bridge chipset was causing the issue (its a very common issue I found out after searching online). Some

Hi all, Our production reported that they found 3 panels out of 53 panels with strange phenomenon after reflow. 1/ Blister / Delamination of PCB panels, 2pcs blister/delamination under solder mask, 1pc under Gold plating at Gold finger 2/ Silkscr

First thing, I wouldn't buy new. There's tons of this stuff out there, the problem is finding the used stuff. One place to look is the SMTnet used equipment sales watteverzits called. Roland knows the name. Most work bench suppliers [eg, Arlink,

Hi Chrissie, This might be old news to you but I just wanted to make sure that you are aware of all the implications of BGA rework relative to the control of moisture-sensitive components. For example, you need to keep track of the total exposure t

Thank you Davef, If I am not wrong in understanding, your answer is mainly related to the Legal point of view according to several different Countries who adopted Rohs or equivalent. My question, sorry for my poor English, is mainly related to the
