Adhesives
Base
laminates for rigid printed circuit boards are copper foils laminated together
with the base materials, the adhesive coming from the prepreg material during
lamination. Contrary to this is the flexible circuit where the lamination of
the copper foil to the film material is achieved by means of an adhesive
system.
It
is, however, necessary to distinguish between two main systems of adhesive,
namely thermoplastic and thermoset adhesives. The choice is dictated partly by
the processing, and partly by the application of the finished flexible circuit.
Sheets
Adhesives / 3M Tape / Tesa Tape
A
sheet adhesive, frequently in the form of a low-flow acrylic, is an adhesive
"cast" on a polypropylene paper from which the adhesive easily can be
removed. The application of sheet
adhesives is frequently used for bonding flexible circuits into multilayer
flexible circuits, or for attaching stiffeners to flexible circuits.
