Ceramic Solder Seal Lids - Rectangle


Ceramic Solder Seal lids are a variation of the metal Combo Lid™ which has been a standard in the semiconductor industry for decades.  Our variation of the combo lid features a flat 90% Alumina ceramic cover with a metalized sealing surface along the outer edge. 

The metalized sealing surface is Ni/Au plated and an industry standard preform (80Au/20Sn) is then tacked securely onto the ceramic cover.  The end result is a ceramic lid that can be solder sealed for full hermeticity that also offers the ease of handling of a metal Combo Lid™ with the added benefits of the ceramic materials. 

Some customers that have used these lids state their products meet JAN,JANTX, JANTXV and JANS quality levels per MIL-PRF-19500 and MIL-STD-750*

Advantages of Ceramic Solder Lids:

  • Increased resistance to salt spray corrosion
  • Improved hermetic seal after temp cycling due to matching thermal coefficient of expansion (TCE)
  • Ceramic surface promotes better marking of finished devices
  • Improved protection from XRAY threat

*Spectrum recommends that customers evaluate these lids in their facility for their specific application and qualification requirements.
