Abstract
The invention discloses a preparation process of an insulated runner plate. The preparation process comprises the following steps: dipping an aluminium plate into an electrolytic bath filled with an electrolyte, taking the aluminium plate as the anode and a stainless steel plate as the cathode, and conducting micro-arc oxidation under the set conditions to form an oxidation film on the surface of the aluminium plate, wherein the set conditions are particularly that the voltage range is 200 to 600 V, the current density is 10 to 18 A/dm<2>, the temperature of the electrolyte is 20-45 DEG C, and the reaction time is 10 to 30 min, and the electrolyte comprises the following components: 15-25 g/L of sodium borate, 2-4 g/L of ammonium molybdate, and 3-5 g/L of potassium fluotitanate. In the scheme, the micro-arc oxidation process is adopted, so that the compact oxidation film is formed on the surface of the aluminium plate; and the oxidation film can ensure that when being hot-pressed under high temperature and high pressure, the insulated runner plate is used with high frequency, does not expand and shrink, and has a smooth, wear-resisting and non-sunken surface.
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 insulation 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 be the spraying coating process also prematurity of this oxide film in another reason that prior art cannot meet this requirement.
Summary of the invention
For the deficiencies in the prior art part, the object of the present invention is to provide a kind of preparation technology of the runner plate that insulate, the runner plate gone out by this explained hereafter can realize the use ensureing high frequency time when the hot pressing of High Temperature High Pressure power, and not breathing, surfacing is wear-resisting, does not cave in.
