Desco - http://www.desco.com/Default.aspx Seem to have a very large range of ESD related products. Sound competent and seem well priced for the products I looked at. This looks like a bargain http://www.desco.com/DescoCatalog/Packaging/StatfreeConductiveFoam/Stat= freeConductiveFoam/12200/ 12150 - FOAM, STATFREE, HIGH DENSITY 1/8'' x 24'' x 36'' $US7.14 Annoyingly thin, but feel the width. They also sell many other thicknesses eg http://www.desco.com/DescoCatalog/Packaging/StatfreeConductiveFoam/Stat= freeConductiveFoam/ and much else. Digikey are agents but light on stock. RS have some in some catalogs. Russell --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
