Abstract

The invention discloses a capacitive touch screen testing bridging plate which comprises an FPCB (flexible printed circuit board), wherein the FPCB is connected with an FR4 reinforcing substrate; an analog electronic signal input connector port is formed in one end of the FPCB; standard IIC (inter-integrated circuit) interfaces are formed in the other end of the FPCB; a capacitor and resistor component socket and jig mounting holes are formed in the FPCB; the standard IIC interfaces are connected with direct inserting type single row needles. During capacitive touch screen testing, the capacitive touch screen good product detection can be achieved only through connecting the two ports of a capacitive touch screen testing bridging plate module with a to-be-tested capacitive screen and a capacitive screen SIU (system interface unit) detection module, the problem that a capacitive screen adopting a COB (chip on board) design method cannot be directly tested is solved, and the capacitive touch screen testing bridging plate has the characteristics of being high in structure strength and easy to operate.

Description

technical field [0001] The invention relates to a capacitive touch screen test bridging board, in particular to a capacitive touch screen test bridging board used in capacitive touch screen production inspections in factories producing capacitive touch screens. Background technique [0002] As the latest computer input device, capacitive touch screen is currently the simplest, most convenient and natural way of human-computer interaction.
