Because the change of temperature can condense steam on chip in journey, so as to cause optical device hydraulic performance decline, and then cause optical module can
Decline by property, or even scrap.The optical device of encapsulation fixed form on to(for) optical lens at present, although optical lens can be entered
Row is stable to be fixed, but can not reach sealing effectiveness, then optical module can have been had a strong impact on along with the temperature change of working environment
Performance, cause the reliability of product and the instability problem of performance.In the prior art, using the symmetrical glue in optical lens both sides
Fixed technology mode is fixed, and this glue technique for fixing mode advantage is can be by the both sides of optical lens and PCB
Plate is all bonded together so that optical lens can be stably fixed to above pcb board, and dispensing mode both sides are symmetrical so that
Structure fixes glue to the force of optical lens symmetrically and evenly, and optical lens is not easy to produce displacement because stress is asymmetric, but adopts
The technology mode fixed with the symmetrical glue in optical lens both sides is fixed, and optical lens light extraction is front and rear to be in non-dripping glue state,
Therefore sealing effectiveness is not reaching to, caused when optical device works because heating up and cooling causes condensation vapor so as to influence its property
Energy.
