Subject: Re: [TN] Inspecting Class 3 Assemblies

Bob,

I am alarmed when you state visual inspection is only 80% effective. I expect much higher effectivity from my inspectors.

When combined with xray, you should be able to achieve 100% inspection given enough time is permitted to look at all connections.

With 100+ PWAs, and 4000 parts/PWA, I would not hesitate to utilize teams of inspectors and sub-regions for their inspection area requirements.

If you have time as a luxury, then programming a 5DX and training that team also works well.

Phil

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
