[TriEmbed] Fwd: Surface Mount Components Newbie Questions

[Carl Nobile]

Sorry I sent this to Chip and forgot to click all.

Chip,

The static issue is the one to be very careful about. If you walk on a
staticky rug then touch a component, say good by to the component. At the
point where you can feel a shock it is already way too high and will blow
any static sensitive component. They must be kept in one of those dark gray
static bags. DO NOT use the pink ones, they're useless.

BTW, components do not know if you are a hobbyist or a professional, if the
component doesn't like the humidity it will be damaged in either case.

I always keep most parts in sealed plastic bags. If static electricity is
not an issue, like with resistors and capacitors, you can use clear plastic
bags. I get them at hobby stores, they come in all the right sizes and are
pretty cheap.

Carl
