PizzaFred, Scott mentioned lots of good ideas. Take one of your boards to each vendor and see what it takes to program the board how long it takes for it to become online. I've found some that are easy to program, but require 40 or more assemblies to

Good Morning Roger, The Mirtec's can be adjusted to lower your false call rate. This can be done by reducing the matching percentage for each componnent but the result of this action is that the machine becomes less selective. If you lower them too

If you are in the Americas, I'd contact tech support and they should square you away on that high false call rate problem. They have great WebEx training and troubleshooting. www.mirtecusa.com

Prins: Everyone has equations. Here's one some people use: False call rate = [Number of defective boards, but good at inspection]/[Total number of boards produced] Why don't you ask the people [that calculated the numbers that confuse you] how the

how do i calculate false call rate? i got this equation = [over reject / (total solder joints + components) ] * 1000000 and i got a table which shows data like number of solder joints, components on panel, and number of false call, and the false

This table, is it in a database? And is it indicating the number of component, solder insp. etc based on one board or one panel? It needs to be based on the total number of inspection on your panelized pcb. The equation works, you may just be look

First all, you must define the specific defects that you wanted to screen out by your AOI system based on its capability, so you can allocate the undetected defects on your other means of inspection methodology. Then optimize your AOI inspection para

PPM on AOI, this is our metric for false fail on AOI machines. Our target is 1000 ppm but I'm not sure about this target for low volume. (1,000 false fails on 1000,000 of inspections) thanks
