Alberto: There's no rules, but it works sorta like this: RESISTORS Usually marked in ohms using a standard code: First two numbers is the value Third number is the multiplier 102 = 1.0 x 10� ohm = 1000 ohm = 1 kW CAPACITOR Usually not marked. When

Scott, We always regret to see a dedicated user leave the fold. Over the past few months we have made many changes to the site, and we believe, improved the quality of the forum experience for our users. During our recent site upgrade we respond

I'd have to agree with JAX here. This forum is intended to be a "Technical Bulletin / Newsgroup" and nothing else. Truthfully, these posts of the "old-timers" announcing their departures is getting..well.....OLD. I hate to see the Old-timers leave

Every critter out there with large incisors adapted for gnawing and nibbling has a different theory of solder ball formation. [My theory: It�s punishment for using NC fluxes. Stand and deliver. My solder balls end-up in the gross filter connected

This is certainly an excellent question. We have shied away from going web based for several reasons: 1. Yes - bandwidth is a real issue. Research into instructional effectiveness of computer based training shows that students lose interest if res

When the original material was developed, we worked with a team of industry experts from a minimum of four different companies. The material was validated by them, down to the last test question. So this has not, to date, been a particularly thorny

We are currently in release 1.4 and 1.5 of the majority of our courses, partly because we do fix minor errors that do crop up, and release maintenance updates. I infer from your comment that you take exception to one or more of the test questions in

Deon, my first response is YES - big time. You are correct that there are some massive issues here. For one thing, lead free solders are only one solution, as conductive epoxy has also been put forward. This was demonstrated on the TAC line at Ne

There are a number of issues here. One is having good benchmarks prior to training. Most companies monitor production issues like inventory, scrap, rework, etc. A good ESD program would be performing frequent audits and recording deviations. Hard
