Hi! Thanks to you as the first replier!
I do admit it "narrows" the information channels feedback flow by keeping this thread reply limited to "non-commercial" engineering folks, but I already have lotsa war stories from the salesmen around this region, and everyone is saying how good their product is. What I was looking forward to is info on which unit configuration is "good" from a direct-end-user perspective.
We did have plenty of opportunity to hands on with all kinds of new fangled inspection equipments, and final conclusion is human naked-eye inspection rein supreme on the list. BUT human fatigue is one area that cannot be ignored, couple this with variable factors such as GR&R drifters, we try to standardize and ensure a repeatability process control system. Its achieved for the Printer, P&P, Reflow, so how about the inspection stages?
My current data shows eratic swings in the inspection defects filter out by various groups of inspectors. I need accurate defect rates/types data to target and deploy my LIMITED resources, else we'll be firefighting all over the countryside. We need calm rational approach to identified problem areas and solve those problems step-by-step in terms of costing priority .
True we could correlate and retrain those drifters BUT humans tend to need the leaderships to motive them back into position? How long can we keep this up? How often can the customer hear this same excuse/reason "our is a new operator/inspector"?
Gone are the days when components were 1206/0805's and naked eye checking was sufficient. We now face components 0201's and CSP's which scope-aid inspection is mandatory. All this is cramp into smaller PCB estate.
I am personally agreeable that human still is the final judgement decision master. Machine and equipment is to assist the human where their basic functional capability cannot reach optimal performance levels.
AOI serves to remove the human eye fatigue from 24hours running inspection of cramped components in shrinking PCB sizes, and this AOI must perform at repeatable rates which is now at 6-sigma ideal.
"Jazzy" is what happens when white elephants take over.
"Optimal Productivity" is what happens when logical application plans meets to kinetic action in motion.
Pray the machine does not over-ride the human way of life, believe that was what triggered the story behind the Matrix anime series?
