HERMETIC KOVAR HOUSING FOR OPTO-ELECTRONICS
What Customer needs:
A Kovar Housing is needed to house the fiber optic transmitter and receiver for the telecommunication industry. After mounting the electronic module on the Housing, the lead frames and wires are connected through the openings on the side walls. Glass which has a similar coefficient of thermal expansion as Kovar, is used to seal the side holes with the lead wires so as to maintain uniform thermal expansion among the glass and the Housing material. The whole Housing is then hermetically sealed from the top.
Kovar is an expensive material with high nickel and cobalt composition, making it difficult and challenging for conventional machining. Coupled to that, the bar stock material used in machining has long lead time and high MOQ requirement. On the other hand, AMT is able to provide a cost-effective manufacturing solution for our customer. Not only did AMT defied conventional “acceptable size” with this 105mm (4.14in) by 105mm (4.14in) by 1.5mm (0.06in) MIM Housing, AMT was also able to minimize material wastage, resulting in significant cost saving for our customer. The part was awarded the MPIF Award of Distinction in 2003.
