NEW: SCHOTT® TEC TO - Enables actively cooled 10GBit/s laser diodes on a TO footprint
We are experienced in the production of TO headers in all conventional, standard designs and sizes. We also manufacture special TO headers according to customer specifications. Used in conjunction with the right cap, TO PLUS® TO headers form a totally hermetic seal that offers long-lasting and reliable protection to the components housed within, and ensures that the components function properly within microelectronic packaging.
In opto-electronics, TO headers are used in nearly all conventional areas of microelectronic packaging applications - on both the transmitter side (TOSA) and on the receiver side (ROSA) of transceivers, as well as in the area of high-speed data transfer, infrared applications etc... The new TO PLUS® is also suitable for use in high frequency applications.
Micro-Electro-Mechanical Systems (MEMS) represent a new area of microelectronic packaging applications with great potential for growth. These systems enable optical signals to be switched using a range of small, mobile mirrors. At the present time MEMS are predominantly used in the high-tech sector, but are becoming increasingly used in mass applications such as LCD projectors and other image projectors. While data communication applications use only stamped TO headers, shelled TO headers are used primarily on the receiver side of sensor technology applications.
Generally, we can manufacture all standard stamped and shelled TO header designs. As shown in the table below, there is a range of different international standards that have been established over the years.
The types of metal used in the manufacture of TO headers depend largely on the production methods used. Compression glass seals are generally manufactured using cold rolled steel (i.e. AISI 1010), while matched seals are primarily manufactured using Kovar®(ASTM-F15) and Alloy 52 (ASTM-F30).
The TO headers can be plated with various materials (nickel, nickel-gold, nickel-silver), and can also be coated in additional metal layers when required.
