| Looking for help in finding suitable high temp gasket for | use in smt assy support application. | | Gasket used to restrain flex on smt module in area prone | to localized heating due to nearby device removal (hot air). | | Current gasket mtl (neoprene) degrading under temp excursion | and possibly cleaning fluids (std aqueous process) of | rework operations. Est localized temp ~240C. | | Gasket mtl required to be soft, non degraded by assy rework | temps and typical cleaning fluids. | | Any thoughts on suitable gasket mtl for this application? | | Thanks, pbb | Many things come to mind but the properties needed are a little vague. In the rubber area try Viton or silicone rubber, both rated at 500 degrees. In the plastic area there is teflon @ 500 degrees and kapton (polyimide) @ 572 degrees. In the traditional compressable sheet gasket area are kevlar and aramid fibre types @ 700+. Why don't you browse your McMaster-Carr catalog. There is a wealth of materials and application advice. Hhope this helps.
