PLATE KEYPAD, AND METHOD FOR MANUFACTURING THE SAME

摘要

A plate keypad and a method for manufacturing the same are provided to improve adhesion between a low-temperature thermal bonding layer by forming scratches or performing predetermined treatment on the low-temperature thermal bonding layer and a urethane sheet layer. A plate keypad includes a first layer and a second layer(200). The first layer has a plate layer with a predetermined pattern, a screen ink layer formed on a lower surface of the plate layer, and a low-temperature thermal bonding layer coated on a lower surface of the screen ink layer. The second layer has a urethane sheet layer(40) and a silicon pad layer(50). The urethane sheet layer is bonded to a lower surface of the low-temperature thermal bonding layer by being heated under a first condition. The silicon pad layer is bonded to a lower surface of the urethane sheet layer by being heated under a second condition with a heating temperature higher than that of the first condition.
