SMT, the full name is surface mount technology. SMT is a way to mount the components or parts onto the boards. Due to the better outcome and higher efficiency, SMT has become the primary approach used in the process of PCB assembly.

Nowadays, design is increasingly pursuing miniaturization, low cost and high speed of products, especially in the mobile device market , which usually involves high-density  electronic circuits. Using Rigid-Flex Boards will be an excellent choice for the peripheral devices connected through IO.  Seven major advantages brought by the design requirements of integrating flexible board materials and rigid board materials in the manufacturing process, combining  the 2 substrate materials with prepreg, and then achieving interlayer electrical connection of conductors through through-holes or blind/buried vias are as below:

1.FPC—Flexible Printed Circuit, a highly reliable and flexible printed circuit made by etching onto copper foil using polyester film or polyimide as the substrate to form a circuit.  

2.Product Characteristics: ① Small size and light weight : meeting the needs of high-density, miniaturization, lightweight, thinness and high reliability development directions; ② High flexibility : can move and expand freely in 3D space, achieving integrated component assembly and wire connection.
