Do you have a picture? SMTNet HAS the technology now to post pictures. "Disturbed" to the typical Q.E. usually means grainy or dull, or a wrinkly solder appearance. All of this has to do with the "grain structure" of the solder joint. Here's a p

Hello. I'm now investigating the current technological issues on surface mount devices. For example, I want to know the limitation of the surface mount machine. Where can I get the materials for this purpose? Thank you

Hello everyone. We are interested in doing double sided surface mount. What methods are there for doing this. I know you can wave solder some smt components, but what are the limitations. Is there a method of doing this that uses 2 different solder p

Hello, Does anybody know is there available surface mount leds as bright as You can find at http://www.set-system.com ? See the brightest ones? (superflux types would be ok for me). Thanks in advance

RF pcb is all gold with no typical land patterns and multiple surface mount components sharing the same pad. IPC-610-B doesn't speak to inspection criteria. The problems I'm seeing are, insufficient solder, skewed components. Some of the pads have

Hi Doug, Can they be mounted on standard FR4 PCBs & reflowed at Lead Free temperatures? Cheers, Rob.

The Luxeon probably are the brightest available. I say probably only because this changes every day. The Luxeon require special mounting as they must be mounted to an aluminum cored PCB with thermal adhesive and then the leads soldered to the PCB.

Different Solder types are not needed. Surface tension will hold most. Plenty of info in the archives about reflow profiles, weight limitations, etc...
