Pete: What�s a "free issue PCB panel"? Is that like "consigned material" here in the states? In response to your question, several possible approaches (in no particular order): 1 Router approach: 1a Wood working router * Go over to Sears and buy a

Hello Ashok If you are talking about the thousands of volts that is often generated by either simply unrolling the tape to apply or when it is removed from the board after soldering you don't have a lot of choice since it is an insulator. Ionization

| | | I have been asked to supply a maximum shelf life for our assemblied PCB's. I realise this is dependent on so many factors- temperature, humidity, no of layers etc. But does anyone have a formulae for calculating shelf life, or does anyone know

| We are currently looking into purchasing a high volume, medium mix production line. We are considering several different vendors and I would like to know if current users of Siemens equipment are happy. Are the machines maintenance intensive? Ho

Benji: I tend to agree with you that assemblers shouldn't wear make-up. I'm unsure what first level assemblers are tho. I've been down that finger cot/glove route ... 1 If someone is going to smear facial or cosmetic oil on a board, they can do

Oh dear, I tried not to respond but i couldn't help myself. Stop me if I go off into the woods. My guess, Chris, based on your fleeting reference to GF files, is that your SMT machines are Siemens Siplace. If this is so then package orientation def

Hello phil, The use of AOI systems give us the opportunity to auto-collect defect information much the way you're using them now. AOI systems become extremely effective when the collected data is used to perform some positive change into the process.

I got my hands on a used, refurbished machine out of China, which didn�t look quite as advertised. Machine plates, logbooks and other documents are missing. According to the machine supplier, the plates are swapped from older machines to trick custom
