Description
Technical field
The present invention relates to a kind of preparation technology of the runner plate that insulate, be specifically related to a kind of preparation technology of the abrasion-proof insulating runner plate based on differential arc oxidation.
Background technology
When the main body base material on manufacturing line road plate (PCB), need to use electric press that materials different for multilayer is carried out pressing, the principle of work of this electric press is by the processed tacky resin material of Copper Foil (or aluminium foil) conduction heating, and by applying certain pressure, multilayer material is pressure bonded to not a half hour, thus obtained board substrate, and in use electric press bonding processes, for cost consideration, single stitching operation often needs the multi-disc of pressing simultaneously board substrate, and in order to make multi-disc board substrate when pressing, be not affected each other, need them superimposed, and insert a kind of special insulcrete between which, it has insulation, heat transfer, the effect supporting and be separated, this special insulcrete with superelevation planeness is called runner plate.
Runner plate and the maximum difference of common insulcrete are exactly the oxide film that there is a kind of densification on its surface, the performance of this oxidation film layer on runner plate has great impact, in process for pressing, very high to the performance requriements of runner plate, electric press is when operating, both heat of high temperature (being greater than 300 DEG C) had been produced, there is again very strong pressure (being greater than 50MPa), this just needs runner plate to possess outstanding resistance to hot press performance, namely runner plate needs to have very high limit tolerable temperature and limit tolerance pressure, and, more weight is, the surface of runner plate still must can keep flat smooth very after repeatedly hot pressing, surface is depression not, there is not breathing, and in existing technique, also cannot realize this requirement at present, after the runner plate of prior art generally about can use about 100 times at normal temperatures, its surface just starts to occur depression, runner plate is caused to lose efficacy, and at high temperature also only can use and just lost efficacy for about 50 times.And in another reason that prior art cannot meet this requirement be preparation technology's also prematurity of this oxide film.
