I just talk with him by telephone, but can not send email to his email address: Lisiewski@cmfgsolution.com Could you please check this information for me? Thanks & regards,

I would think that wave solder beneath a BGA component might be a little bit stressful. The board will be expanding much faster than the BGA on the topside. This will cause some stress to the solder joints that might show up as the failure you are

Weird question, but I need it for a claim. About how long does it take to assemble, plug in the power and dry cycle a DEK 248 with vision. I'm saying 90 minutes to two hours tops. Additional opinions would be greatly appreciated.

Depends on to what degree it has been disassembled; How much verification of repeatability is required; and if everything actually works... 2 hour - 2 days.

I'm with you on microcracking. The best way to confirm this is through sectioning of the affected capacitors. You're fortunate to be seeing these failures showing-up early in your product life. Of times these failures don't appear for years.

I would look at your de-paneling process. How are you cutting the boards? This could be inducing mechanical stress on the component; especially if the part is close to the edge of the pcb and perpendicular to it.

Most likely the depaneling is not your issue, but I do concur that there is some mechanical stress occurring somewhere. What about any fixturing for FT/ICT?

Hi, Could someone help me in identifying the component in the attached picture. I guess it is a regulator. I am trying to understand whether it is faulty or not. The input is around 5V and the output is 0. Thanks..

Looking for a manual for Elecrovert Omniflo 7 Reflow Oven. Anyone got an extra copy? Mine seems to have walked off :O/

Absolutely! The Solder paste needs to be brought to room temperature or close before opening. It like bringing a cold glass from the refrigerator when the humidity is high,water will condensate on the glass. It also will condensate on the solder and
