I bought a number of through hole IR receivers, which I used to test a=20 simple device. Subsequently I have designed a board and ordered up some=20 SMD versions of the same thing (http://tinyurl.com/665gafn). However, the bag comes with a rather nice sticker explaining how these=20 are moisture sensitive. In the bag is a humidity sensing patch and a=20 lot of warnings. This is a hobby board and I'll only make one or two, but I'm wondering=20 how moisture sensitive these things are. In general, are moisture=20 sensitive parts a pain? Or am I going to be OK once I've soldered them up? David --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
