When you need cover lids for high-reliability applications in semiconductor, MEMS, crystal oscillator, medical and optical devices,
our unique patented Combo-Lids™ and Ceramic Combo-LidsTM can function in the harshest service environments.
The base metal of our high performance Combo-Lids™ is Kovar™ 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 precious metal (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.
Our one-stop station tack-welds Gold-Tin, Lead and Lead-free solder preforms onto metalized ceramic lids. Our metallization capability creates an effective seal ring that allows excellent soldering. Gold-Tin alloys provide superior hermetic sealing and edge melting provides fillet formation. Other non-precious and lead-free soldering is available as well as tack-welding service for soldering preforms onto ceramic lids.
