ABSTRACT:
The present invention provides a packaging structure of a gas detector and the method for making the same. The packaging structure of the gas detector includes a printed circuit board, a detection device and a ventilation cover. The detection device is attached to the printed circuit board by adhesive, and metallic wires are formed on the printed circuit board by wire-bonding process. The ventilation cover is positioned at the printed circuit board to cover the detection device. Signal terminals of the detection device are electrically connected with the contact terminals of the printed circuit board so as to test and check signals of the detection device. In this regard, the present invention is used to test and package a plurality of detection devices using one printed circuit board and without metallic terminals so that cost of the gas detector is significantly reduced.
