BGA & QFP post reflow inspection

Electronics Forum | Wed May 04 15:01:23 EDT 2005 | Dr. Klein

Thanks siverts, The problem with open the sealed MSD bags before the production, is from the rezone that we don�t know exactly when the production start. If we will open the bags before production there is a possibility that the component will be ou

Temperature testing

Hello!! Where can I find some materials and information about temperature testing?? We have a new temperature testing chamber and i would like to know how fast product will cool down and after that how soon can I put this product to high temperature

SMT line validation

Electronics Forum | Wed Feb 22 10:45:05 EST 2006 | Gilligan

FDA = Food and Drug Administration. Typically, the FDA requires a validation of every product that will ultimately go to consumers. The validation process is the basic "run it the same way with the same results" over a period of time. Back in my Phar

RoHS Revolution? Pb Push-back?

Electronics Forum | Wed Jun 07 14:41:29 EDT 2006 | Bert van den Berg

The European consumer is protected from reliability issues due to RoHS. Remember, two year warranties are mandatory in the EU and you only get one chance to repair a defective product in the EU or the law requires it to be scrapped. If the customer

%RH in the Production Hall

Electronics Forum | Mon Jul 17 11:28:16 EDT 2006 | SWAG

Lower RH = more static build-up on production floor = greater chance of ESD damage to product. Primarily, I think your SMT print job can be affected by RH which could cause defects like the ones you mention. Look at ANSI/ESD S20.20 for more info an

AOI Setup Verification

Electronics Forum | Thu Jul 27 05:02:11 EDT 2006 | Rob

If you don't have too many products to run, keep known defect boards for each product and run them through as a first & last off. That way you know if it has drifted out. Yes I appreciate it's not always easy to have a spare defect board/golden sam

Cracking

Electronics Forum | Sat Sep 16 12:44:29 EDT 2006 | Grant

Hi, Could it be shocks in transit? This is only happening on 1 product, so might point to chassis and packing design. Does anyone know of any shock indicators that we could put inside the chassis to see if the faults are caused by this? I have seen

I have checked your website and your product is more on LED signage. Wow! This product is very good to market. Anybody from your sales department can contact me for marketing of your product. My focus is in Asia. I will ask my former engineers who

how to measure an assembly cost of a board

Electronics Forum | Thu Aug 14 07:42:28 EDT 2008 | davef

You can assess these costs anyway that makes sense to you. These machinery costs are 'direct' to the product. You could call them manufacturing overhead or machine cost. It all depends on what makes sense. As an example, depending on the products you

How to identify SMT line's capacity

Electronics Forum | Wed Jun 23 01:37:38 EDT 2010 | tpvnew

Thanks for the input and advise. Yes, indeed, for single or just few products, to get the lowest ones should be no problem. However, I am facing so many products in the line, and the mix is changed all the time, it is difficult (for me, at least) to
