In the past year I was responsible for developing and leading a Team focused on AOI, Evaluation, Justification, and with a full ROI required, supporting a HMLV manufacturing environment. If you have in these economic times the additional resources t

I'm looking for a chart that will help me identify smt resistors and capacitors. I have figured out a few on my own. a resistor with the numbers 510 printed on it was a 51 ohm resistor. numbers 221 was a 220 ohm resistor. numbers 102 was a 1k resis

I read a few posts here about resistor in led applications. The thing is, the resistor has clarified as this shows:was always use with a power source delivering a higher forward voltage than the led could tolerate(ex: a 9volt battery hook up to a 3w

The majority of SMT resistors use the following notation. 10 X eg 153 represents 1k5 resistor The third digit in the sequence denotes the number of zeros to add after the first two digits giving the value in ohms. Many Caps will follow the same nota

We are currently experiencing a high rate of false calls on our 0402 chips. Resistors for the most part. Has anybody out there found a setting where this false calls are minimized? We are using top red light, pattern inspection,color inspection ( wh

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus

Programming is different, yes, but so is the terminology. ///with machine vision you have parameters that select what is good and what is bad, and you have parameters that help make bad look worse and good look better making the difference between w

some things to consider, Is there flux on the board. are there finger prints on the tops of parts. Is the board warped at the V score from reflow Is the board shifting in the machine during inspection. These are the issues we have had with our mir

Hello John, the answer of your question is more organizational than technical. Most CEM use their own part number system(you will need to purchase software for that), and that is exactly what you want to do.You can have 5 different resistors 10kOhm

I am currently finding it challenging(help!) to determine how I can introduce SPC ontrol within the AOI process and how the AOI can help control other SMT processes. Can someone please provide me with some ideas or any of excels fancy charts/macro
