Title: Bonding height detecting device
Inventor: ENDO TAKAHIRO
IPC: H01L21/607
Filed: 1988-11-25
Abstract: PURPOSE:To obtain a bonding height detecting device, which is noncontact, highly reliable and capable of responding quickly, by a method wherein the relative movement of a housing block and a holding block to each other at a time when a capillary is abutted on a bonding surface are detected by a magnetic sensor and a bonding height is detected. CONSTITUTION:In a wire bonding device, when a housing block 5 goes being rotated to the direction shown by an arrow for setting the reference position of a working head, a capillary 2 is abutted on a substrate 1, can not be moved anymore and a holding block 4 is also stopped there. However, as the block 5 can be rotated while a spring 6 is stretched, the block 5 and the block 4 are moved relatively to each other. As a result, the relative displacement of a magnet 15 mounted on the block 4 is detected by a magnetic sensor 14 mounted on the block 5 and a signal is sent to a control apparatus. Moreover, the control apparatus controls the amount of motion of the capillary after detection of this signal with the reference of the position of the capillary 2 at the point of time. In such a way, a detecting part is non-contact, and is never subjected to abrasion and deterioration with time. Accordingly, the reference of a bonding height is stabilized and the device can follow sufficiently a high- speed operation.
