Gelot™ solderable coatings
Light sensitive semiconductor devices require a packaging including a transparent glass lid. Soldering is the assembly technology which provides best hermeticity values of such packagings. Gelot™ solderable coating gives the glass a surface with good adhesive properties for soldering such as Gold or Palladium. Gelot™ is applied to the lid as a frame pattern with a clear aperture.
