Abstract
A protection tape for a printed circuit board (PCB) includes an insulating base plate, a conductive layer over the insulating base plate, and an adhesive layer over the conductive layer, the adhesive layer including a main part having a first thickness and a subsidiary part having a second thickness less than the first thickness, the main part corresponding to at least a center portion of the insulating base plate and the subsidiary part being arranged at an outside of the main part.
Claims22
A protection tape for a printed circuit board (PCB), the protection tape comprising:
- an insulating base plate;
- a conductive layer over the insulating base plate;
