Description
Technical Field
The invention belongs to the technical field of optical communication device packaging, and particularly relates to a semi-airtight packaging device and a semi-airtight packaging process for an optical device.
Background
In the field of optical communication active optical devices, the packaging of the active optical devices is divided into two modes, one mode is airtight packaging, and the other mode is non-airtight packaging. The advantages and disadvantages of the two packaging methods are briefly described below
The airtight packaging method comprises the following steps: the enclosed space is filled with inert gas, and the seal assemblies are combined by resistance welding or other fusion welding modes. Such as the common TO package, BOX, butterfly package in active optical device packages. A leak rate of less than 5e-8atmcc/s for hermetically packaged devices is generally achieved as per method 1014.10 at MIL-STD-883G. The advantage is that subassembly sealing part adopts the welding, effectively isolated outside steam's erosion, and inside inert gas that fills simultaneously is difficult for condensing into liquid when receiving high low temperature to change, and the dual mode prevents effectively that steam from corroding photoelectric chip or parts. Especially, the element such as TEC is corroded by moisture, so that the working efficiency of the element is reduced and even the element is damaged. The disadvantages are that: the adopted welding method for sealing is a technical method, like resistance welding, the used material is generally kovar metal, the requirements on the flatness of base processing and the like are high, sealing welding equipment and a BOX \ TO header are expensive, and the repairing and the recycling of components are difficult after welding. Which is a constraint on the packaging process and cost.
The non-airtight packaging method comprises the following steps: generally, a method for dispensing and sealing an optically active device by using glue is adopted. Such as the COB packaging process common to active optical devices. The advantages of this packaging method are: the process is flexible, the pipe body and the shell can be processed by self, and the cost is low. The defect is that the air tightness is poor, and the internal air is easy to be condensed into water vapor to be attached to the surface of the element or the glue to damage the element due to the change of the temperature, so that the service life of the optical device is short.
The semi-airtight packaging process method provided by the invention aims to combine the advantages and evasion defects of the two methods to form a semi-airtight packaging process method, so that the service life of an optical device can be between the two methods
