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

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

Has anyone caried out a DPM analysis on these components. I would be interested to know the defect rates and other assoc. placement issues as we have never placed them before. Thanks, cath

I'm not sure if anyone mentioned the single most important factor. p.m.'s. If the nozzles are getting dirty and clogged it's not going to do a great job of picking parts up. Don't think in terms of variation. It's there it's unavoidable and undet

any advice on smt resistors and capacitor that can survive an explosive shock. the ceramic smts are not, plastic ic's and discretes do fine.

We are taking enquiries for sub-contract work that we hope to be doing by Christmas. One of the enquiries is to assemble chip capacitors and an SO14 onto ceramic. Does the printing process, paste used and reflow process remain the same, or are there

Agilent TestJet Technology White Paper In the early 1990s, the testing of digital parts became problematical. Previous in-circuit test techniques sought to ensure a correct, functioning part by applying digital patterns, called vectors, to the input

Well that doesnt sound very promising. What im going to do is make sure these two boards I just coated (with the RTV already cured) will be used in house only. In the future we will do any conformal coating operations before potting with whatever mat

| Does anyone have any experience they are willing to share on Ag epoxy used as a copper through hole plating replacement? Was CEM3 used? | What are the limitations? | Thanks, | Steve I have used silver epoxy extensively for conductive bonding applic

Earl, et al, Boy things get old and cold around here fast. I promised more detail on my capactior problem and I thought I could drop something completely different in the same message and tell a tale of solder balls. First the caps. We still have
