Adhesive Systems for Optimal Performance
For our flexible circuits, we utilize advanced adhesive systems to bond copper foils to film materials effectively. Two main types of adhesives are employed:
Thermoplastic Adhesives: Suitable for specific processing requirements.
Thermoset Adhesives: Chosen based on application needs.
Sheet Adhesives: 3M and Tesa Tape
We use sheet adhesives, primarily low-flow acrylics, applied on polypropylene paper for ease of removal. These adhesives are perfect for bonding flexible circuits into multilayer configurations or attaching stiffeners, ensuring the highest quality connections.
