Problem with a MPM HiE

Sounds like you have detent option enabled. Check to make sure that your board X and Y dimensions are correct.

Is there any good articles to read on solder paste?

I have another idea. Would you check the apertures on the stencil? May be they didn't cut the right size apertures there. If you have smaller aperture you can't get the right amount of paste.

Check to make sure the side covers are closed. It is probably an interlock problem. Also if you have carts...make sure the plunger switches are down. Good Luck

Tin Oxide on Solder Joints

Walter: The things I'd look at first are: * Temperature of the water wash. I expect the solution to be in the 140-150*F range [Check with your flux supplier for recommended temperatures] * Temperature of the boards when entering the cleaning process.

Vacuum sealing of MSD components

In previous lives we vacuum sealed all MSD devices. Also a nitrogen chamber can be used for unsealed bags. You can check the J-STD-033 and J-STD-020A for handling of the different levels, bake times etc. Good Luck!

SPM problem

2 things can cause this 1. Go in and empty the temp folder on the C drive 2. Check and see of the lights are on on your alignment cameras. If they aren't there is an issue with the 24V power supply.

Using an AOI for TH solder checks

Electronics Forum | Fri Aug 02 17:29:40 EDT 2013 | joeherz

Haven't done this but would start by contacting YesTech tech support and explaining what you are trying to do. They should be able to provide guidance including "..our equipment isn't intended for this application..." if that applies. Good luck.
