Bob,

Agilent 5DX does a really good job of speeding up (automating) X-ray inspection, but just like AOI, it's not the "last word". The slices can be flagged as suspect, but it's still in the operator's hands to make the call. Sometimes confidences can be increased with articulating X-ray with a good operator at the wheel.

There are a few companies out there that offer 5DX services for a price, but the programming might be prohibitive.

Subject: [TN] Inspecting Class 3 Assemblies

Dear Technetters:

I think these things come in bunches.

We are being asked to perform contract inspection of Class 3 medical PCBs.
I would categorize this board as "high complexity" with BGAs, UHDI connectors, 0201s and about 4,000 parts. There are 100+ boards.

Obviously performing this manually will would take many hours and based on previous experience, be only 80% effective using a single set of eyes.

So my question for those of you building IPC-A-610 Class 3 product for mil, aerospace or medical is how do you insure that class 3 solder joint and other inspection criteria are met? The AOI we have will not do the trick!
The leadless devices and BGAs we will inspect via XRAY. Other ideas for doing this "offline"?

Bob W/BEST
