I have been re-evaluating the way we do our visual inspection processes due to its apparent ineffectiveness. We recently tested this theory by introducing 6 obvious defects on one assembly and gave it to one of our "experienced" visual inspection ope

Hi You are right. I guess some of us missed this point in the way this on line dialog works. I like to put the specification that the PCB supplier must adhere to, on the Physical Print. The Physical print is often used by outgoing and incoming insp

Hello AR, Yes we are inspecting SMT that has been wave soldered. We are not inspecting solder on through hole components. We have actually found the solder inspector works better for wave solder SMT joints than reflowed. The system is great at ident

Hi, I work with Omron AOI for almost 5 years. Sorry for the late reply, but I visit this site very seldom Basically Omron are considered as the best in solder joint inspection because it used patented 3 colour highlight principle and in 99% the missi

In my experience, the best way to do a lifted lead inspection on a QFP is by laser height measurement. It is very difficult to consistently catch a lifted lead with only a top down camera. As you say, too many false calls, and still some escapes.

Has anyone had any luck programming using the side cameras to inspect for defects on the sides of chip components? We recently had an escape of a damaged chip capacitor that was impossible to see from the top camera but was clearly visible with the

The SimmScope is an inspection system that uses an overhead digital microsope on a motorized gantry to inspect the board - much like an AOI - except that it does not automatically make the pass/fail decisions. It is up to the operator to make the de

I've always approached it like this: Design your processes and perform your work to class three standards, and inspect to the standard that is acceptable. That is, all work should be performed to the highest degree of quality. When the work is ins

The closer your inspection the more defects you will find, the more rework you do the possible cost you will add and the potential increase of damage you could do to your products if rework is not up to a machine copyable standard. "Is there any in

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
