I have experienced some dewetting problem on the photo-coupler's lead. No matter what types (how strong) the pre-cleaner and fluxes I used, still not completely resolve this problem. I just wonder, why this is so common to have dewetting problem on

Via failure could be caused by cracks in the barrel, or thin plating, or fractures in the traces leading to the vias, . X-ray analysis could pick up a fractured trace and cross-sectioning of the vias could pick up the cracks and thin plating. Secon

I do have access to an X-ray but it is only 2-D and it just appears as a black solder joint, not to impressive.. The main question though if it is a reowked solder joint does it still need to show wetting on the lead or can it be covered with solder

Hi I uploaded the photos http://hk.photos.yahoo.com/ee02lyk of the failure samples. The chip-cut and pin-hole were found after the manufacturing process. I initially suspect the crack happened during the reflow process.However, our factory analysis d

OK I can take a hint when asked for a photo. I did not try to take a photo as I thought the close up image would put the picture out of focus, so this is where a bit of graphics works might help explain the problem. When I had a look at the 1206 p
