MULTI-LAYERED PRODUCT FOR PRINTED CIRCUIT BOARDS, AND A PROCESS FOR CONTINUOUS MANUFACTURE OF SAME |
摘要 |
<p>The invention provides a low energy loss, multi-layered polypropylene/metal foil product useful for further processing into printed circuit boards and antenna boards for microwave circuitry. A continuous process for manufacture of the product is described. The process comprises the steps of: providing metal foil; optionally, extrusion coating molten polypropylene upon said metal foil, to obtain a foil coated with a polypropylene foundation layer; casting a molten polypropylene tie-layer upon said metal foil or upon said coated metal foil; and laminating a polypropylene sheet on said tie layer. In the process, heat is applied to induce fusing of the layers of the multi-layered product.</p> |
