Hello,

Attached is the X-ray picture of a SMT transistor. Please give me your opinion whether this is a good solder or not. From my view, I did not see any solder in the middle pad. I feel it is a production problem. But someone told me unless you see the void under, it is a good solder. Please help.

Thanks.

Hi Melanie, Can you provide pictures of the solder connection itself? I've found that xrays can sometimes be misleading.

Melanie: We're with AVFOM. If you don't believe there is solder on the pads, use a beer can opener to pop the component off the board and you will have your answer. Easy-peasy.

Who ever told you 'if there is solder, there is voids' in solder connections is wrong. Stay away from him / her.

Melanie, Given the examples of the solder joints in this and surrounding components, I would believe that there is no solder present.

Hi Melanie

The centre pin got solder but not fully as other 2 leads. U better provide the x'sistor from the top view.
