Is the COB shielding cover for the optical module plastic or metal
It involves encapsulating the optical chip in a metal box filled with inert gas (usually helium) to protect the optical elements from external environmental influences and enhance heat dissipation. Box, COB, and TO can are currently the most prevalent packaging forms for optical components. COB packaging integrates components directly onto a PCB, enabling miniaturization and cost efficiency. This method offers a compact package size and high integration level, which is particularly beneficial for applications requiring dense configurations, such as. COB packaging is a non-hermetic technology where chips are mounted directly onto a substrate, connecting through soldering or wire bonding. Today, we will discuss the differences. COB (Chip on Board) and BOX (Airtight Package) are two types of primary packaging technology in fibre optic transceivers, one solution can be advantageous over the other dependant on use case and form factor.
