Hello, We have a need for thin core ( .006" to .008") FR-4 laminate that's transparent to UV light. Our current suppliers only produce laminate with a UV block, adding dyes or multi-functional resin to their Fr-4 resin formulation. Does anyone know a source for "old fashioned" FR-4 di-functional laminate without the UV block (i.e. white not yellow)? Please advise. Thank you, Dan Brandler, Ohmega technologies, Inc. ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC's web site (http://www.ipc.org) "On-Line Services" section for additional information.
