Multilayer Fpc Flex Printed Circuit Board Low Cost Gold Finger Manufacturer Flexible Pcbs
Materials Used in Flex Circuits:
Now we will discuss the basic materials used in making flex circuits.
Conductors: Conductors allow the electrical current to flow freely. Copper is
the most commonly used conductor while other materials used include
aluminum, carbon, silver ink etc.
Adhesives: Adhesives are used for surface mount component binding. Adhesives
are used according to the customer needs and thickness of
conductor. Some adhesives that are used include epoxy, acrylic or
PSAs (Pressure Sensitive Adhesives). Some circuits are built
adhesive less.
Insulators: Insulators are used to separate electrical conductors without
conducting current themselves. They are also used as support. Some
common insulators include polyimide, polyester, solder mask,
polyethylene naphthalene and polyethylene terephthalate.
Finishes: Finishes are made to protect the metal surface from oxidation. The final finish depends on the application of the circuit. Some common finishes include solder, tin, immersion in nickel or gold, silver, carbon etc
