Dear Joe,

The issue is we use no flow prepreg between the flex and the rigid portion. And though the prepreg is no flow, a little amount of the resin comes out and hardens on the edge of the rigid portion which necessitates a depth control routing. This affects the aesthetics of the board.

What should we be using for instead of the prepreg. Can we use polyimide adhesive which is routed to the shape so that no flow happens.

Pl give us some details on the process to be followed including the material
