ABSTRACT:
A method of making a thin, lightweight and flexible RF waffleline includes the production of a negative silicone casting from a relatively thick and rigid metal positive tooling plate having the identical matrix of the desired waffleline and product. The waffleline is formed by casting an epoxy resin on the silicone casting or nickel electroforming, following by metallization. The waffleline end products is either a very thin and flexible epoxy composite structure or a nickel electroform metallized with gold. Accordingly, a negative WMA image can now be cast, as opposed to expensive machining or forming, with relatively simple and inexpensive techniques in fabricating the process tooling.
