Hi, Just wondering while reading this thread, would 0402 caps be more immune to stress because they are smaller? Regards, Grant

Hi, Sorry to drag this thread up again, but we were recommended to change the wave to SAC305, but is everyone recommending SN100C? That seems to be the feeling on this thread. What flux is used? Regards, Grant

Hi, If the stencil was not cleaned well from the previous run, dried paste residue can cause the paste to grab in the stencil. If you have a microscope, check the small apertures for contamination. Regards, Grant

Dear Grant, Thank you for the reply. It is really a valid reason and I did check for it but nothing turned out that way. Can you think of some other reasons if the process parameters are the same used earlier when there was no problem at all. Regard

Hi, I would say the most worrying defect would be damaged parts due to exceeding their temp specifications. Regards, Grant

Hi, Does it really matter what temp the oven runs at as long as the PCB's are profiled correctly? I mean we run boards through all the time to check profiles, so as long as that's ok, would it matter what the oven though the temps where? Regards,

Cheers Grant, I found that very helpful too - we're going over end of this year to take a closer look at Aus & NZ (my other half was over there a long while). Thanks, Rob.

Grant, I think this Guru has never set foot onto a production floor. He just looks at data from the machine manufacturer. As you have found out the hard way this data is not the full story. Jerry
