I know that some board houses have better capability than others. Some can do down to 4mils mask in between the leads I think. I know that it also depends on the type of the mask they are using - for some types you can't go down to the 4mil. Regards,

We use the PDR machine. Great bit of kit. We prefer it due to the IR heating on the top. No air is used to potentially blow neighbouring components that go into secondery reflow off the board. We have a Zevac to but thats not as good. Camera is

Per IPC-A-610D: Target is 100% vertical fill but 75% vertical fill is acceptable for Class 1,2,3. Only needing 75% fill of the barrel when soldering plate through on an 0.093" thick board with our selective solder has been a life saver at times.

No, each card in LP servo rack drives only one motor. But there is an servo cotnroller board (actually 3 of them) in the VME rack (where all computers are). Third one from the left(slot13) controls head2 theta and z axis. That might be a cause of you

Accuracy of the arbor press might be made better by tightening the adjustable gibs on the ram if any. If you can use support under the board have the ID of the support just slightly larger than the pins being pressed. Janesville Tool makes an accura
