Circuit board module

Abstract

The invention relates to a circuit board module (300), relating to the field of touch control engineering, and capable of improving anti-static capabilities. The circuit board module (300) comprises a touch control chip (20), a first circuit board (10), a second circuit board (30) and at least one electrical connection part (40), in which the touch control chip (20) has ground pins (22) and signal pins (21); the first circuit board (10) is electrically connected to a touch control display (200); The first circuit board (10) has the first grounded part (14) and signal attenuators (12); the signal attenuators (112) are connected to the signal pins (21), so that the touch control chip (20) is connected to the touch control display (200) by the first circuit board (10); the first grounded part (14) is connected to the ground pin (22); the second circuit board (30) has the second grounded part (32); and at least part of the conductive wire (40) is connected to the first ground (14) and the second ground (32)
