Title:
MANUFACTURE OF PIEZOELECTRIC COMPONENT
Document Type and Number:
Japanese Patent JP3206034
Kind Code:
B2
Abstract:
PURPOSE: To improve the quality by dripping wax heated to a high temperature onto the front side of a base to move the wax from a side face to a rear side, dripping wax heated to a low temperature onto the front side so as to form a wax layer to the rear side and the front side without reversing the base thereby preventing the occurrence of a crack.
CONSTITUTION: Wax W1 adhered to a dripping iron 10C is heaped to a front side 2a of a piezoelectric base 2 while heating the iron 10C to keep the temperature to be nearly 110°C. After the wax W1 is sufficiently moved from a base side face 2c to a rear side 2b, the iron 10C is lifted up to cure the wax 1 thereby forming a wax layer 6B onto the rear side. Then wax w2 of a smaller quantity than that of the preceding processing is kept to be nearly at 70°C similarly to the case above and heaped to the side 2a and then the iron 10C is immediately lifted up and the wax is cured to form a front side wax layer 6A. Thus, it is not required to reverse the base thereby preventing the occurrence of a crack due to reversing and improving the quality.
