Selection and use

How to select

What is supplied

Kovar flat lid with Au80Sn20 solder. The package body, die and sealing service are separate.

Dimension check

The nominal body is 6.90 x 6.90 mm. Match the lid, sealing ring and package surface using the current manufacturer drawings.

Sealing scope

A lid alone does not establish a hermetic package or an assembly process. Confirm the substrate, lid surface, adhesive or solder, tooling and actual batch condition together.

Quantity and delivery

Send the exact model, required quantity, destination and target date. The RFQ form accepts requests from one piece; the supply minimum, available quantity, price and delivery date are confirmed in the quotation.

Drawing and compatibility

The dimension diagram is an MST schematic from the manufacturer numeric table, not a photograph, PCB footprint or manufacturing drawing. Ask for the current model drawing before ordering.

Typical applications

  • Use the current manufacturer drawing to confirm dimensions, tolerances and process compatibility.
  • The RFQ quantity is a requested quantity, not a promise of available stock or a confirmed manufacturer minimum.
