Gold wire fixing structure for gold wire bonding

Abstract

The invention discloses a gold wire fixing structure for gold wire bonding, and specifically relates to the technical field of gold wire bonding. The gold wire fixing structure solves the defects that an existing gold wire bonding mode does not have other fixing modes except for a mode that two ends are fixed, a gold wire is at a relatively active state, and, when the gold wire is pulled and dragged, a welding spot loosening even fall-off phenomenon occurs easily. The gold wire fixing structure for the gold wire bonding comprises a gold wire angle positioning member, the gold wire angle positioning member is provided with a plurality of mutually independent wire penetrating passageways, the wire penetrating passageways comprise wire incoming straight passageways and wire outgoing straight passageways, an outer port of each wire incoming straight passageway is a wire incoming port, an outer port of each wire outgoing straight passageway is a wire outgoing port, a 90-degree inclined angle is formed between a wire incoming direction of each wire incoming port and a wire outgoing direction of the corresponding wire outgoing port, gold wires penetrate the wire penetrating passageways, and a non-conductive adhesive is injected in gaps between the wire penetrating passageways and the gold wires.

Description

technical field [0001] The invention belongs to the technical field of gold wire bonding, and in particular relates to a gold wire fixing structure for gold wire bonding. Background technique [0002] The existing microstrip connection adopts the gold wire bonding method. After the gold wire is bonded, there is no other fixing method except the fixed points at both ends of the gold wire. The gold wire is in an active state, and the stability of the bonding angle cannot be guaranteed. When the gold wire When being pulled, it is easy to loosen or even fall off the solder joints, the stability and reliability are low, and it is easy to cause open circuit or short circuit, with serious consequences. [0003] In microwave transmission lines and microwave devices, gold wires are required for circuit connection and grounding. Due to space and bonding position requirements, gold wires need to be bent 90 degrees to ensure correct connection. The existing gold wires are directly expo...

AI Technical Summary

Problems solved by technology

When bonding the second end point and assembling, it is easy to cause the gold wire to be pulled by force, causing the gold wire to be straightened, and the required angle disappears; or the gold wires contact each other, resulting in a short circuit; at the same time, the gold wire solder joints are prone to loosening Even falling off, communication disconnection, in severe cases, the falling off gold wire or solder is lapped to other circuits, resulting in burnout and damage to the device
