Its been a long time since I've worked with the Quads but if I remember right I've seen this error when the bearings went bad in the theta on the heads. Usually you can feel it when you try turning the Z-rod. Should be a nice smooth motion with littl

Hello, our products are made on single-sided boards and we often have problems with receiving too warped PCBs from our suppliers. Can anybody suggest a good laminate or the most important properties of the material so we could specify it when we orde

My APS GF12 seems to have lost it's settings randomly last night, and it won't let me run any profiles unless it's autotuned. I've figured out the security password and can get into the tuning menu, but not sure what to do from here. Anyone know wh

Ideal storage conditions to stop pcbs absorbing moisture is at less then 5% RH, for example in sealed moisture barrier bags. You mention that storage was at 40~70%...at these levels the pcb will absorb quite a bit of moisture. Your baking time was no

When you say Fine Pitch is this .5mm or is it smaller? I wonder what problems they experienced with HASL, the only problem I recall hearing was the surface was not flat. When applying paste with a stencil I can not see how the flatness is an issue.

Use a 0.002" to 0.003" thick stencil. Use an electroformed stencil from Photo Stencil or one of the others. Use -500 +635 paste or a -500 paste or type 5 or greater paste. I have printed at 0.008" pitch with 0.004" pads. It can be done.

Both units have the 50 pin cable, but no drives are present. The service manual makes no reference to a disk drive (that I can find), is it possible that the floppy is a 'secret' factory tech-only service tool of some sort? Also, with the 50 pin cab
