http://www.mgchemicals.com/products/832.html Loctite makes a version too, if I recall. Designed to be tamper evident, but yes, rework is a bear. We had similar results using one of Lord Chemical's urethane potting compounds. It was a filled black fi

The Eclipse really looks like it would do everything I'm doing now very well. I'm not too clear on how well the laser/1D vision would work for QFN parts, but maybe it would be fine. The downside is I think these machines are now going to be hard to

then would crash everytime. Not to give up, started to experiment with the markers inside the vios text file. The hack was to remove the MARK fields inside the file. After this, saw the component layout in the GUI PCB view with proper references. S

I've been running 90% lead-free (still have a couple components I can't get reliably in RoHS compliance) with a peak temp of about 238 C, on standard FR-4 boards. The only real problem is the pad adherence is compromised, making rework of the boards

OK, I am really happy with the robustness of my CSM84. I wonder how hard it would be to hack up one of these 3-phase machines to run off single-phase power? Mostly, it just feeds a big DC supply for the X-Y servos. 2 heads with ANE should be just FI
