Optical communication encapsulation shell gold finger

Infrared detector housings are essential for protecting both uncooled and cooled infrared focal plane detectors. These housings are widely used in various industries such as infrared night vision, security, firefighting, maritime operations, surveillance, power monitoring, smart grid online monitoring, visually enhanced assisted driving systems, and railroads. There are two main types of infrared detector housings: metal wall-ceramic insulator and full ceramic. Metal casing: This housing consists of a metal chassis, metal wall, ceramic components, and a copper exhaust pipe. The integration of the copper exhaust pipe within the casing ensures multiple leads and high reliability. The metal shell is typically designed in a butterfly structure. Ceramic shell: This housing is predominantly made of LCC (Leadless Chip Carrier) and PGA (Pin Grid Array) types, with the option of including or excluding an oxygen-free copper exhaust pipe. It is characterized by multiple pins, the absence of a…
