The SimmScope is a first article 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

I have moved golden boards from chains to mesh as I got tired of fishing t-couples under the chain rail. I saw a 3-5 deg. decrease on top-side parts peak temp. (all t-couples were on top side). I had to bump zones 6 and 7 a few degrees to make up f

We can find quite a few number of Pros/Cons on Template matching vs Algorithm Based. But this morning I have explored a new technology on "Cyber Optic" AOI. The technology called "SAM" (Statistical Appearance Modelling). As long as your manufactur

Hi, Besides the 2 machines mentioned which are part comparison machines that require the operator to provide a pass/fail on each ref id, there is a system called the FA Inspector which offers the mode described above and two additional modes: 1. Au

Automation and low cost is an oxymoron sort of like jumbo shrimp. Automation will set you back $20,000-100,000. Optical comparitors aren't cheap either. Low cost means good eyeballs, a "golden" sample board and up-to-date documentation. Also low c

The best way to compare is ask each machine company to bring their machine in for a demo. Since they are bench-top machines, they are easy to transport. Pick one of your boards for them to run. Don't send any board data ahead of time. When they come

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

Hello!!! Just to say, I've never even heard about placing parts on double-sided tape for inspection... We always build one board placing parts on paste/glue and inspect it befor reflow. With suppliers specs of 6hours at least, I don't see any prob

As always, our good colleague Evtimov is right about the AOI and oven. For the AOI you need to make a golden sample board(panel) and test if your machine can catch all defects that you simulated BEFORE the oven. Try to me as accurate to real defects
