1" long SMT components to be placed without coplanarity issues> Also, what types of finishes are common for the flex;i.e, ENIG, immersion Ag, etc.?

We use the Mirtec system and are very pleased with it's consistency and reliability. We also are satisfied with its ease of programming and ease of use for the operators. I do agree that the 5 camera system would be best, as well as the optional la

Remember as well, the Mirtec machines have laser technology being used to check for coplanarity/lifted lead issues. Having this capability will reduce false calls in most circumstances.

Dave's mirror should work. If you're not up to building it, check out http://www.fancort.com/smt/aids_mirror.html Regards, Mike

what about the selective 3D option;do you use it. what about the coplanarity issues.

Dave Thanks for the input. The thermocouple read 244 on the pad of the socket. We actually found after extensive investigation that it is the coplanarity of the leads. We were shipped a bad batch of sockets form the manufacture. Go figure!!1

We are looking for a recommendation for a company that can perform solder ball inspection on BGAs. The devices are in trays and the the challenge is the ultra fine pitch (0.4mm) and ball size (0.25mm diam). We are looking for ball diameter and coplan

Also coplanarity can be poor on these parts so overprinting the paste (beyond the pad perimeter) can increase volume to insure robust solder joint.

Of course, the more accurate the better. However, it might be a challenge to calibrate with really precise one - still better to take your time and do it right. Good luck!

Based on these pictures, please check Board/Stencil co-planarity. Sometimes there might be a distance/gap between them helping this phenomenon(solder mask might be too thick). Also decreasing print speed, might help to mitigate it. You might be too f
