Hi Folk, what is the possible cause for the components (e.g ICs) to be Solder shorted? I know that one of the cause is the solder paste height is too thicked. Could anyone advise me on then possible root cause and solution(to minimize the rate of so

I have used infrared imaging to find electrical shorts on logic boards between the 5 Volt buss and ground. You can power the electrical short up to draw 50 to 100 mA and then look for the warm spot in the infrared display.

Your statement is interesting, but not necessarily correct. Are shorts in the same location? Is it one short or multiple? Are there any vias in the BGA pads on the PCB? Is part MSD and handled as ESD?

John: Seek your answers in the archives. As I recall someone said: � Biggest cause of BGA shorting was out-gassing in-package moisture. � Removing shorts w/o removing the device: - Preheat the board - Lower the nozzle and heat the device - Lift the

We are finding solder shorts under 1206 Components on the bottom side of our boards.In all cases these shorts are from either side of the component to a feed-thru under the component body. Adhesive is used to glue down the component and then the boar

Hello all, Are BGA's easy to develope shorts? If a process is stable and all of a sudden you get BGA's shorting out on you, what might be problems? We've checked our solder paste amount, and we've rechecked our reflow profiles and nothing has chan

What side is the short occuring on. Topside or bottom (solder) side? 2. Pitch of hole pattern = ? 3. Your x-ray may not have the resolution or DSP capable of detecting this defect. How does your profile look? Is this a true short or the result
