Thanks for the reply Mike, I will look forward to see the end result of your investigation (e-mail people_1@fsmail.net). Regarding the test machines, I was trying to ask what are the suited/or recommended from your experience, set of test equipment

Hello , In our case we take the results from the repair station. Each test station has its own repair station so from there we count the process defects : placement and printing. The formula used to calculate PPM = DEFECTS / (PARTS PER BOARD x UNITS

Dear friends, I'm from Spain and, in this moment, we try to decide what AOI we need. We had in floor, in Demo, the SAKI, and it was good. But we want to test more machines, and I heard about Omron, Modus, Mirtec.....We have a litle production but so

Every time to create new AOI program we must manual set at bright lighting level for each component. then this case we think the parameter of AOI setting it not concern for this problem due to the golden board that we use to confirm machine before st

As the face of business changes through revolutionary factors, such as the increasing rate of outsourcing, manufacturers (especially EMS plants) will strive to fine tune their test strategies to ultimately improve and sustain product quality and to r

If you are just wanting to test the values of the electrolytics or tantalums, it's not a problem with an ICT, as long as your system has an analog instrument to do it. If you are wanting to test the polarity of the cap, you will need a capacitive co

When testing components on a PCBA, try to validate coverage for presence, correct, orientation, live, and alignment. AOI is not really great at catching cold solder joints and damaged components, and from my experience an X-Ray is only as good as the

We have a YesTech YTV 2000. I'm being asked to set up a program to test the destination solder on through hole parts to make sure there is a lead in the hole and there is solder in the hole. If possible I need to test for bridging also. This is being

Hello Phil, sorry for the confusion, because of our level of defect control and tracking at each process step, we did not use AOI systems at the time. We had a manual inspection station after reflow, then ICT and Functional/Final test for each produc
