| Recently, someone in the SMTNET forum had installed a Wells-CTI Z-Lok socket and found that it was one row off from the board layout pads. Was the problem due to a layout error or was the datasheet incorrect? Dave ol' pal...dat wuz me...

Hmm, that's a fairly old machine, even older than mine! (I have a CSM84 PA130640). Anyway, it is best to program the machine from CAD system data, I wrote a little program in C to read in the component type and XYR position, and produce the file in

Can anyone point me to a relevant IPC spec that specifies an allowable board stretch, measured between metal features on outer layers (e.g., between fiducials and component pads on the topside of a board)? I've got a non-linear stretch problem that'

Hi guys, Sorry I haven't posted in awhile...but here are the details.. The noise in the cam box is the C-axis coupling. (Sr.Tech was right) Applying a little oil to the coupling pins killed the noise, but cam back in a few hours. We are in the proce

You can do the so called "Golden Sample" with defects from the process. The making of the defects on the board is very important to be as much close to the real ones from the production. How I do it - after the printer I remove paste on some pads, so

SP1 is a bi-metal spring loaded switch or the "air fault" switch on the main air manifold that detects the presence of an appreciate amount of air being supplied to the machine. Air pressure overcomes the adjustable spring and closes the contacts.
