RESIN COMPOSITION, PREPREG, AND PHENOLIC RESIN PAPER BASE LAMINATE

摘要

THIS INVENTION RELATES TO A RESIN COMPOSITION FOR USE IN FORMING A PREPREG. THE RESIN COMPOSITION COMPRISES A NOVOLAC-TYPE PHENOLIC RESIN CONTAINING PHENOL DIMERS OF 15 WTOR MORE OF THE TOTAL WEIGHT OF THE NOVOLAC-TYPE PHENOLIC RESIN, AND RESOL-TYPE PHENOLIC RESIN. A PHENOLIC RESIN PAPER BASE LAMINATE MANUFACTURED USING A PREPREG FORMED USING THE RESIN COMPOSITION HAS EXCELLENT HEAT RESISTANCE WITHOUT ANY LOWERING IN VARIOUS PROPERTIES OF THE LAMINATE, SUCH AS PUNCHING PROPERTIES, ELECTRICAL PROPERTIES AND THE LIKE. THIS LAMINATE IS CAPABLE OF WITHSTANDING A HIGH TEMPERATURE ATMOSPHERE IN REFLOW SOLDERING USING A LEAD-FREE SOLDER.
