Hermetically Sealed Windows and Feedthroughs

S-Bond active solders bond to ceramics and metals, making then very suitable for hermetically sealed optical windows and electric/signal feedthroughs into vacuum or hermetically sealed enclosures. Sapphire, alumina, and quartz have all been joined to metal housings and enclosures to include titanium, stainless steel and Kovar. S-Bond’s lower temperature joining process, compared to brazing for hermetically sealed windows and feedthroughs, increases the reliability and lowers the cost of bonding such assemblies.
