Design Guidline #1 Designer's Guide for Laser Hermetic Sealing Introduction

چکیده
Precision components or sensors exposed to corrosive conditions, or required to have extreme performance characteristics, are sealed hermetically into special packages. Epoxy glueing, resistance welding, soldering, electron-beam welding, and laser welding are several of the techniques available for sealing these packages. The disadvantage in the use of epoxies is that they do not create a hermetic seal. Moisture migrates through the epoxy, destroying its hermeticity.

Ultrashort pulsed fiber laser welding and sealing of transparent materials.
In this paper, methods of welding and sealing optically transparent materials using an ultrashort pulsed (USP) fiber laser are demonstrated which overcome the limit of small area welding of optical materials. First, the interaction of USP fiber laser radiation inside glass was studied and single line welding results with different laser parameters were investigated. Then multiline scanning was ...
متن کاملPlastic Hermetic Packages for MEMS?
The sealed hermetic package is over 100 years old if we include cathode ray and vacuum tubes. While the package has changed, the idea of making a near-perfect gas-tight enclosure has remained constant. The metal and ceramic full hermetic package may be required for applications that cannot use the non-hermetic plastic package, but is there an intermediate package choice? During the last few yea...
متن کاملNovel application of polyelectrolyte multilayers as nanoscopic closures with hermetic sealing.
Closure systems for personnel protection applications, such as protective clothing or respirator face seals, should provide effective permeation barrier to toxic gases. Currently available mechanical closure systems based on the hook and loop types (example, Velcro) do not provide adequate barrier to gas permeation. To achieve hermetic sealing, we propose a nonmechanical, nanoscopic molecular c...
متن کاملDevelopment of Bion Technology for Functional Electrical Stimulation: Hermetic Packaging
BIONs are chronically implanted, individually addressable, single channel electrical stimulators that are now in clinical trials. They receive power and command signals from an externally worn RF transmission coil. The electronic circuitry is packaged in a glass capsule that can be injected through a hypodermic needle to provide distributed multichannel FES systems. The small size (2mm OD x 16m...
