Hello, mcdvoice It seems like your Juki RS-1R machine's laser height calibration may be off. When measuring a 0402 resistor, it consistently reports heights around -0.60 to -0.70, causing pickup issues during production. Manually adjusting it to -

We had a similar system on the Siemens machines, quite some time ago. However, it was not a laser light but a LED and a fiber cable. Actually the center fiber or receiver was surrounded by a bundle of small fibers for the LED light source. You may al

Yup. It was definitely checking the fiducials as well as the block skip marks and it used to work pretty well. What it did was started at the center of where the fiducial should be and scanned left. When it found a change in contrast it scanned righ

Ken, You'd think so but the tooling pins only register to the drilling process for the PCB. The fiducial registers to the copper pattern and for both glueing and placing SMT components the pads are more important than the holes. That's why the machi

Ken, Thanks for the feedback. Unfortunately (or fortunately) I am in Mexico and we make our own PCBs. That is another conversation entirely and another of my fix-it projects but currently we drill the PCBs and align the artwork to the holes visually

Lasers can go quite often, but if you are lucky and not in a great hurry you can get them refurbished dirt cheap. If you have a good 750/760 that has been well maintained it should run for a long time, but if it has not been loved you can end up payi

Thank you Bobpan! I checked the laser sensor and could see through the glass a small stripe (dash)in the inside lens, just in the middle of it. Thank you again.

Hi, I have two Quad IVc and both of them have the same problem. Laser Alignment is not working! When I run funtion 30, it always gives 1 at nozzle height. If I place any object beside the nozzle, it will give a number different from one depend on how
