All you can do is to revise the testing procedures and SMT checks (pick and place vision and AOI checks) with the same fault generated in-house. This is all you can do from my point of view.

If you have any kind of inspection, record any faults found. If you've got an RMA process, record any faults found. Should rework and/or RMA's hit unwanted numbers, you may want to include additional inspection in your product documentation during bu

A configuration of a number of AOI tools located at different inspection stages along the SMT production line has, by its nature, the ability to provide a faster and closer response to possible process related fault occurrences. Comparing with today

You could spend 30 mins inspecting a modestly complex board manually using a magnifier/scope and still miss things. Humans get distracted, bored and tired. It is also difficult or impossible to visually inspect some faults like mild tombstones or qu

I have problemabout fault reject rate at AOI very high, due to inspection letter or marking on IC body. It have uncleary. When I check at raw mat'l of IC it no problem but after pass reflow process it show marking not clear ( Laser marking type). Ple

Hi all, Having a major problem with an IC being placed upside down. We pick up the fault at AOI. We have check several reels and the component is not placed upside down by the supplier. Where should I start looking; 1. Are we using an incorrect fee

Thank you for kindness advice. From the result of IC after pass the reflow process. The color of letter will change to similar color of material compound of IC. Then when we inspection by AOI machine, we have many problem about high fault reject rate

We are already using ICT on the PCB, which should catch most missing components, also components installed backwards, or the wrong value(to a point - we do RF so we have lots of very small value caps and inductors which can't be measured), and in som

Teradyne says, "How does one evaluate the competency of a particular AOI system? At the highest level, all potential customers must judge any viable AOI system using the following qualities: * Throughput must be able to match the line rate on the man

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
