Portable electronic device with a surface mounted technology touch pad

摘要

A portable electronic device with an SMT touch pad comprises a main printed circuit board and an SMT touch pad. The main printed circuit board has a top surface arranged thereon an SMT area, and a bottom surface, wherein the SMT area has a plurality of conductive pads arranged in a first pattern. The SMT touch pad has a touch surface and a mounting surface formed thereon a plurality of conductive pads with solder arranged in a second pattern that is a mirror of the first pattern on the main printed circuit board. The mounting surface of the SMT touch pad is placed onto the top surface of the main printed circuit board and the SMT touch pad is soldered onto the SMT area of the main printed circuit board.
