Abstract
An optical detection device with enhanced electrostatic discharge immunity includes a circuit board, a lens component and a case. The circuit board has a plurality of electrodes. The lens component is disposed on the circuit board. The case includes an accommodating chamber and an opening structure. The accommodating chamber is adapted to accommodate the circuit board and the lens component. The opening structure is communicated with the accommodating chamber. The case further includes a rugged structure disposed around the opening structure and adapted to engage with the lens component for extending an electrostatic discharge path from the opening structure to a nearest electrode of the plurality of electrodes.
Claims15
An optical detection device with enhanced electrostatic discharge immunity, comprising:
- a circuit board having a plurality of electrodes;
- a lens component disposed on the circuit board;
- and
- a case comprising an accommodating chamber and an opening structure, the accommodating chamber being adapted to accommodate the circuit board and the lens component, the opening structure being communicated with the accommodating chamber and aligning with the lens component, the case further comprising a rugged structure disposed around the opening structure and adapted to present an all-around symmetry for remaining distances of all orientations between the opening structure and the rugged structure being identical and synchronously increased, and further to engage with the lens component for extending an electrostatic discharge path from the opening structure to a nearest electrode of the plurality of electrodes.
