Materials Reference For The EE
Q: This would definately fall into the "Everything Engineering" category. I keep needing some sort of materials quick reference which is useful to figure out what the best material is when I have to make a decision which is more materials engineering than electronic engineering. Let me give some examples: 1) I recently needed to insert a sheet of something underneath a circuit board to prevent accidental contact with the live contacts by mounting screws inserted into the keyholes provided for mounting in the enclosure. I knew about thin phenolic board, but couldn't come across a source (which is another whole issue), but realized some sort of plastic might work. After much much much research (consisting of what seemed like an endless string of google searches), I figured out that teflon was high temp (which I needed) and offered exactly what I needed. 2) In dealing with enclosure vendors they say greek things like "this is HIPS UL-HB is that ok?". I have learned that UL-HB isn't really what I want, that UL-V0 is better, but that doesn't help me understand the difference between HIPS and ABS, and the like (I sure can't tell any difference). And searches aren't a lot of fun. So, I generally ask for things like melt point and the like. I'd rather just be able to look it up. 3) I recently discovered emachineshop.com. Which is really cool, except that there's like a million different materials listed. How am I to know the difference between the 20 types
