Abstract
An electronic element which is free of many of the impurities that tend to adversely affect its operation. The electronic element is hermetically sealed in a space formed by a framework having a first and second plate directly joined to its sides. Directly joining the first and second plates to the framework prevents splashes of adhesive and soldering material from effecting the operation of the electronic element.

A manufacturing method for an electronic component comprising the steps of:
- producing a framework by forming an opening through a first opening plane and a second opening plane on opposing sides of a base plate resulting in an opening entirely through the base plate;
- fixing a first plate onto said first opening plane of the framework;
- mounting an electronic element inside of the opening formed in said framework;
- fixing a second plate onto said second opening plane of the framework;
- and
- heating the electronic component resulting from the preceding steps, thereby directly joining said framework and first plate, and said framework and second plate, respectively.
