Hi Mark, There are many tools available for measuring solder paste height. Most machines use laser as the basis for inspection while others use structured white light. If simple height and width inspection is all that is required, you can look int

RLM, you have been very helpful! Let me try this on you: We have two IVC's, one with a conveyor and Quadalign, the other with a workholder platform and Cyber-optic. I just ran the first successful assembly on this second system, but the extents had

Hi: Our machine (QUAD 4C) has a CyberOptics laser 6604033; when initialize at HOME, z-rod descends and doesn't retracts, which makes me think that the laser is misaligned, here's a link to the video recording: http://www.youtube.com/watch?v=W9ma7Zsf

Hello Bob, we changed the nozzle z parameter until we got limit errors and backed up 1 mil. There was a slight reduction in the limit errors on the pickup of the component but it is still a problem. With the mod code we adjust the soft z height to ab

Thanks Bob, I will change the z-rod just to make sure. It is a tall part read at 180. The nozzle height bugs me because we have 3 machines and the first one has a nozzle height of 238 while the 2 others around 200. I am thinking this parameter may ad

The way its supposed to work...is....when you do a function 30 the z axis should step down until the nozzle tip is seen in the quad align or laser align. The readout should have a nozzle height but if its the earlier firmware for the machine it might

Larry, I have had this problem in the past. It turns out that there wasn't enough "Z" on our nozzle pickup locations. When a nozzle change occured the nozzle would not be fully seated on the Z-rod. When the Z-rod is driven down to pick the first part

It sounds like it's just failing the laser align step. Try changing the align type for the part to "2" and see if it places it. If it's failing the laser align and you have valid part dimensions I can't help much but you might consider opening up th

Hi All, agree 100% on product characteristics SPC, and do find process indicators such as paste Volume, useful to monitor via SPC, the printing process, as printing constitutes "70% cases of SMT defects". We juz purchased a 2nd hand CyberOptics 3D

Hi All, We juz purchased a 2nd hand CyberOptics 3D paste inspection machine (what a mouthful...) and am seeking info : 1) what formulae is applicable, to calculate the deposited solder paste volume onto the pre-defined PCB pads? 1.a) from our obse
