There is no actual book on HOW to program equipment. The books that Bob mentions all deal with the theory of SMT, and doesn't go into the nuts and bolts of how to program a machine.

Just like to know what you guys thoughts regarding mixed alloys. Production run SAC305 and some components are SAC105. So, which profile should you follow. SAC105? or SAC305.

Why not follow SAC305? you would do so for any other component finish wouldn't you? A component finish of pure Sn would also not call for a pure Sn profile, would it?

We've found that reverse homeplate reduces tombstoning significantly for us on 0603 and 0402 (the latter of which we hardly ever see).

Another sticky issue is that if you use after market nozzles especially mixed in with Fuji nozzles the Anti-Marking Illumination Disks can be different enough that the vision system will reject nozzles. Jerry

I've had some that under normal light they looked the same but when the UV light hit them they were very different.

The right paper incorrectly applied can be a problem also. I have seen it on even new Fuji nozzles with the illumination disk bunched up on one side of the tube with a gap on the opposite side.

Thank to all for the help. The problem was the reflective disk. They're all green now. Thanks again. I got another error but I'll start a new thread because it is not related to the disks.

Your circuit would consist of: * White noise generator * ~30Khz bandpass filter * Amplifier * Power supply You can find modules for these functions on the web. Good luck.
