R axis is the rotation of the heads. 180 degrees and -180. The sensors tell the machine when the heads are switched correctly on the flying nozzles and the correct rotation. also i think they involve the clutch as well. After i make an adjustment to

we do see some inconsistencies with fiducials. We use X, Y references in the machine but still find them with the camera to populate pcbs. But just can't always center the cross-hairs in the fiducial. Most of the time we have to offset the cross-hair

What is the best way to introduce a choke like from a drawing? Emerald often misunderstands the number of pins - pads have an irregular shape. Also with the lifting is a problem - for the nozzle 63 is too heavy and rotates when moving, the nozzle 64

Solved it last week! Thank you all for your help. PRoy I wish you posted that earlier :) it would have saved us time and effort. We did extend the soak time(from 65s to 80seconds) in the reflow profile which resulted in a better wetting and stronger

Your silver immersion layer is dissolving in the solder. I presume this is what is meant to happen. But with copper tracks underneath that should be fine. Does your SAC305 cover all of the pad. If so no problem. If not then you will need to flux your

the tarnishing is happening across all the traces without solder even being applied. The PCB is soldered into the housing first. Once this is complete the traces have changed, and when it is time to solder the components to the traces this tarnishing

When the pcb is inserted into printer, the camera moves from the origin to the stop pcb, after a few seconds the message "axis camera error" "out of time" appears. In the next few days I make a video of the operations done and the error that appears

This is going from my memory from a long time ago...but in the scp.ini file....there could be digital light control and/or a matrix tray handler setting. I would turn them off if they are on. I believe this has something to do with a system setting.

Has anyone found a durable, indelible inspection stamp ink? We have an extreme case of smearing/obliteration because we have the boards dip coated (Humiseal 1B73). The manufacturer of our stamps is zero help, i.e., the best I could get out of them

I figured it was just going to take a little searching to find a (more expensive) stamp that used an (more expensive) indelible ink. Not the case. Just can't find anything at all, and the stamp manufacturers say not to use any ink but what they provi
