Hi Melissa, We mount this component in the bottom side with adhesive epoxy and the solder is done on the wave solder machine. During the wave solder machine, we have the problem as like the picture.. no solder in one of the pads...

SWAG may be correct. The program files, the defect data, and images do pile up. You will also experience this is you have a lot of components that are not linked to your libraries. These too will add up over time, and cause considerable slowdown. '

Ryan, in some cases we use 2 pastes with different melting temperature (LF SAC and PbSn)for complex boards with components on two sides. And we want to try to replace LF SAC with low melting paste.

Dear colleagues, can anyone tell me who manufactures or where can I source the (IEC 286-6 and EIAJ 7201) standard bulk cassettes for SMD components? I have googled a lot without success... Any help is greatly appreciated! Thanks!

SAC305 - it's just a metal composition of solder paste. All properties of solder paste depend on chemical composition of flux and other components - I don't know their names in English, sorry.
