Component Database and Placement List

For package shapes/names I would recommend using manufacturer names. This is much safer than coming up with descriptive names like QFN32_5x5 as there are multiple 5mm 32Pin QFN shapes even when pitch is the same, this makes it safer to use a name in

We had some defective camera's on our GSM's. The repair guys wanted $12,500US for two replacements from UIC. I found rebuilds at this place in New York State for $249 each. They have been working great for two years now. I even got back $30 for the o

Prolly the worst. I'm sure it depends on who you get, but Cali not only looks for things that affect the waste stream, but will report on things not up to code, and the biggest being they look for earthquakes violations.

Bad business practice and disrespect to SMTnet

The nerds say they've fixed the problem. They say the problem was caused by bad, obsolete code. Based on my review, I believe that they corrected the problem. Good job nerds!!! Hopeful, our faith in man [and woman]-kind is restored with this fix.

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
