mickd, I prefer a rail of 7.62mm (0.300"). This alows for the tooling pins and fiducials without any trouble and minimizes the waste. A fiducial of 1mm round with a 1mm clear area around it. Jerry

What is the humidity level in your facility? We maintain ~40% year round and never have any issues regarding ESD from cover tape peeling.

It seems to be no solder paste release at certain stencil opening, you may need to enlarge the stencil opening. By the way what is the area ratio for the opening and how is the shape (round/square/diamond)?

I'd like some recommendations on the type / size of quad fiducials to use. I started with a small + on the silkscreen layer, but i think that a via is better, and have been using it. Now i'm considering a round smd pad, but not sure the size. Any

From what I remember, the round encoder on top of the Zfi head comes preassembled with the shaft. It's made in Germany. I don't remember the manufacturer, but the name and p/n might be on the label.

I have been asked a very good question but have not been able to find a good answer. IPC for both PCB and PCBA refer to the X & Y dimensions to measure warp and twist but how would you determine the warp and twist for a round PCB or PCBA?

Whats the best way to joint a broken conveyor drive belt? Ive tried a rubber glue which lasts for a short time and tried touching both sides to an iron tip and then holding together, again with poor results.
