A product where a circuit of copper foil is formed in one side based on Base PI Applies to cable which requires continuous curves and the manufacturing cost is cheap

A product where a circuit of copper foil is formed in one side based on Base PI Less flexible than single side FPCB, but density of circuit and components is high because they can be installed in both sides.

A product with 3-tiers or more circuits thanks to multi copper foil (conductor) circuit. Applied to multi-function and compact products since circuits can be highly dense, but manufacturing cost and defect rate go up due to multi-structure.
