Flexible printed circuit: Used for ease of assembly in interconnection systems

Posted by markwahl barg on May 18th, 2018

Flexible printed circuits arewidely used today because of low cost, ease of assembly in interconnection systems, and the low volumes that they occupy. Board-to-chip, board-to-board, and chip-to-chip connections are areas where they are mainly used. They are also important in packages with limited space and stacked rigid boards, thus demanding three-dimensional connections. The largest use of flexible circuits can be seen in portable electronic products. These include notebooks (NB), mobile phones, personal digital assistants (PDA) and information appliances (IA).

The medical electronics industry is one of the fastest growing markets. As the drive to reduce space and weight while adding functionality at a reduced cost continues, flexible circuits are becoming an ideal interconnection and packaging design solution for this industry. A flexible printed circuit makes use of flexible laminate. The raw materials and properties of the laminate are crucial, not only to its manufacturing process, but also to the performance of the finished circuit. The flexible laminate consists of a conducting foil and also the dielectric substrates.
