Problems solved by technology

The laser fixing technology often used for C-mount laser welding wires is to clamp the fixing hole of the C-mount laser heat sink block with tweezers with one hand, and gently place the laser on the copper plate in the middle of the feeder of the wire bonding machine, and then feed The pressure plate on the device moves down to fix the laser, and the other hand adjusts the position of the laser by manipulating the control handle of the device. Press the button on the control handle, and the P knife of the wire welding machine moves down to weld the gold wire to the COS and the upper end of the electrode. , complete the wire bonding work of the laser. After the wire bonding is completed, lift the pressure plate, and use tweezers to remove the laser from the copper plate to complete the wire bonding work. This fixing method is used for C-mount laser wire bonding. The method is simple but the operation is more troublesome. , only one laser welding line can be carried out at a time, and it is difficult to operate without long-term professional training

During the laser welding process, the operator will inevitably touch other structures of the laser, which is very easy to cause product pollution caused by human factors

Moreover, due to the poor fixation of the laser on the wire bonding machine, the vibration generated during the wire bonding process will easily cause the laser to move, resulting in a large deviation in the position of the laser welding wire, resulting in poor welding accuracy and difficult to guarantee consistency

At the same time, due to the very thin thickness of the electrode and the soft material, it is inevitable that the electrode will be bent during the wire welding process, which will affect the quality of the product.
