Description

Optical device receiving end coupling clamp

Technical Field

Background

In the optical device packaging process, the process for connecting the emitting end is generally glue adhesion, and due to various errors, the PT end needs to be coupled to light to meet the process requirement. The process generally comprises the following steps: coupling, dispensing, pre-curing and reinforcing. The coupling fixture covers three steps of coupling, dispensing and pre-curing. The existing industry practice is that a chip 1 is usually installed on a specially-made plastic charging seat 2 and connected to a circuit board 3 through a clamping claw 4, and in some schemes, the circuit board 3 is omitted and directly connected with a board card. The jaws 4 are made of copper alloy, and have certain elasticity to provide relatively stable clamping force. The whole coupling clamp only provides the installation of the chip, and the clamping is completed by the clamping jaws. After the coupling is completed, dispensing is performed on the periphery of the chip 1, after the UV lamp is irradiated for a certain time, the product and the chip are bonded through ultraviolet glue, the chip 1 is taken away from the charging base 2 together, and then the next process is performed, as shown in FIG. 1.

The traditional scheme has good effect on conventional products (with the communication rate of 2.5G), low cost and relatively good stability, so that the method is widely applied. But as technology continues to advance, conventional products are gradually replaced by higher end products such as 10G, 25G, and the like. The sensitivity of high-end products to position is improved, and when the chip exits the claw 4 along with the product, the existence of drawing resistance is inevitable, and unbalanced stress can lead to NG of the product. Other solutions are available in the industry to address this phenomenon, such as replacing the latch 4 with a separable pin to eliminate the stress on the chip due to the power-on structure. However, in the actual use process, a certain drawing resistance still exists due to various factors such as the energizing socket, the chip pin bending and the like. In order to solve the phenomenon, the design adopts a scheme of automatically powering on and automatically withdrawing, the withdrawing mechanism only bears the force on the chip base, all known influence factors which can generate drawing resistance on the chip are eliminated, and the adverse phenomenon caused by the drawing resistance is greatly reduced.
