What do you call ESD safe bags? The pink poly bags are non charge generating but not static dissipative. The plastic can hold a localised charge and that can induce a charge separation in something you put on the plastic. So I think that means you ca

Hi mate, no complete info given from what i see, so just some humble comments, mayhaps you review : 1) PCB pad finishing - Copper+nickle plated? coz if so, nickle is a KILLER to good solder wetting. what we did back here, was to HAL coat the nickle

I'm in the middle of developing an ESD program at my company, trying to adhere to S20.20 as much as possible (and the suggestions of the ESD audit conducted before I got here). I've been discussing the pros/cons of pink-poly foams and black foams.

Actually that reminds me I remember one place I visited that wore two heel straps for saftey purposes. The reasoning was that if you touched a live wire with one hand and only had the heel strap on the other foot the current would go through your he

Hello all. Thanks for taking up your time to read my post. In this age of questing for ever-more-efficient circuit designs, I have been presented with an anachronistic design problem: I need to keep a roughly constant load on a steam-powered turbine

Sorin: Formulas for calculating heat dissipation of traces don�t seem to provide practical results. But there are some wonderful tables and graphs that will meet you needs. You may need to do some finagling when calculating vias and through holes,

What is the package type? TO92, TO5...etc. This temp. sensing device clips (mechanically) to the sink. And this requires a special tool? How about thermo bond heat sink compound? "output" by loc tite is the only flavor I can think of...There a

Sal: When western companies first started studying Japanese companies, they found the Japanese using a technique called "poka-yoke." It means mistake-proofing. In this, the designer specifies parts and assemblies so that they can be assembled one
