Combo-Lids™
Materion’s Combo-Lid™ is a leading choice for hermetically sealed microelectronic packages. When you need cover lids for high reliability applications in semiconductor, MEMS, crystal oscillator, medical and optical devices, our unique patented Combo-LidsTM can function in the harshest service environments.
The base metal of our high performance Combo-Lids is KovarTM or Alloy 42, which is plated with nickel and gold flash, and tack welded to a solder perform, usually AuSn eutectic. The nickel layer inhibits corrosion, while the gold layer promotes solderability and ensures a clean particulate-free surface. Tack welding the solder preform to the lid conveniently aligns the solder to the perimeter of the lid, simplifying handling and reducing part count. Hermetic Combo-Lids therefore offer a best-cost solution.
