1, supporting thin basic and flexible circuit board (FPC);

2, can be used for irregular shape of the substrate and can carry multiple boards to improve production efficiency;

3, to prevent the substrate in the reflow when bending deformation, so that the substrate to complete the formation of solder, to ensure quality improvement efficiency;

4, Synthetic stone is the most commonly used SMT tray material, it has the advantages of high temperature resistance, low heat absorption, good flatness and long service life.
