Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a packaging shell for an optical communication module. Background Technology

[0002] In today's information society, the amount of data is growing explosively, constantly increasing the demands on communication bandwidth and transmission rates. Optical communication, with its advantages of high speed, high bandwidth, and low latency, has become the cornerstone of modern communication networks, and optical communication modules are the key components for realizing optical communication.

[0003] Regarding the aforementioned technologies, the inventors believe that during the operation of an optical communication module, the internal optoelectronic devices generate a large amount of heat. If heat cannot be dissipated in time, it will lead to a decrease in device performance or even damage, affecting the stability and lifespan of the optical communication module. On the other hand, the sealing performance of the casing is not ideal, and external dust, moisture, etc. can easily enter the casing, causing contamination and damage to the delicate optoelectronic devices, thereby affecting the transmission quality of optical signals. Therefore, an optical communication module encapsulation casing is proposed to solve the above problems.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the aforementioned issues, this application provides a packaging shell for an optical communication module.

[0006] The optical communication module packaging shell provided in this application adopts the following technical solution:

[0007] An optical communication module packaging shell includes a shell body, a substrate fixedly connected to the inner wall of the shell body, a mounting groove formed on the outer wall of the substrate, a module chip mounted on the outer wall of the mounting groove, a plurality of solder joints on both sides of the outer wall of the module chip, a plurality of pins formed on both sides of the inner wall of the shell body, and a plurality of pins corresponding one-to-one with a plurality of solder joints, a gold wire provided between the pins and the solder joints, and the gold wire connected to the solder joints and the pins, a sealing groove formed on the outer wall of the shell body, and a cover plate installed on the outer wall of the sealing groove.

[0008] Preferably, multiple mounting stickers are provided on both sides of the substrate, and a heat-conducting plate assembly for heat dissipation is provided above the module chip, and the heat-conducting plate assembly is adapted to the multiple mounting stickers.

[0009] Preferably, the outer wall of the mounting groove is provided with a silver paste adhesive layer, and the mounting groove is installed and fixed to the module chip through the silver paste adhesive layer.

[0010] Preferably, an epoxy resin sealant and a fluororubber sealing ring are provided between the cover plate and the sealing groove for sealing and fixing.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The mounting slots and silver paste adhesive layer allow the module chip to be mounted onto the substrate via the mounting slots and silver paste adhesive layer. The substrate is made of ceramic to facilitate heat dissipation from the module chip. A heat-conducting plate assembly is then installed on the module chip to further dissipate heat, improving the device's heat dissipation performance. Epoxy resin sealant is applied to the sealing slots, allowing the fluororubber sealing ring to mate with the slots. Finally, the cover plate is installed onto the sealing slots, improving the device's sealing performance. Compared to existing technologies, this method effectively dissipates heat generated inside the optical communication module, reducing the temperature of internal components and improving device stability and lifespan. It also protects the delicate internal optoelectronic components from contamination and damage, ensuring stable optical signal transmission quality. Attached Figure Description
