在线接合操作中之短尾恢复技术;SHORT TAIL RECOVERY TECHNIQUES IN WIRE BONDING OPERATIONS

摘要

提供一种线材接合机的操作方法。该方法包括：在线材接合部形成之后检测短尾情况；将线材接合机的接合头组件设置在线材接合机的xy位置处；使接合头组件朝向位于xy位置处的接触表面下降；打开线材夹；使接合头元件减速，从而使得线材的一部分延伸到线材接合工具的末端下方；闭合线材夹；以及执行测试，以确认线材延伸到线材接合工具的末端下方的端部是否与接触表面接触。; providing a bond head assembly of a wire bonding machine at an xy location of the wire bonding machine, the bond head assembly carrying the wire bonding tool; lowering the bond head assembly toward a contact surface at the xy location with a wire clamp of the wire bonding machine closed; opening the wire clamp; decelerating the bond head assembly as it is lowered toward the contact surface such that a portion of a wire extends below a tip of the wire bonding tool; closing the wire clamp; and performing a test to determine if an end of the portion of the wire extending below the tip of the bonding tool is in contact with the contact surface.
