| 20120055931 | Technique for creating vacuum sealed packages - A method of sealing a package includes plating a perimeter of a hole formed in a package and attaching a solder film to the plated perimeter, the solder film covering the hole. The method further includes assembling a device in the package and sealing the package to define an interior and an outside, the device being contained within the interior. Next, the method includes heating the assembled package in a vacuum oven to a predetermined temperature where the solder film bonds to the plated perimeter, evacuating the vacuum oven to form a vacuum until the solder film fractures as a gas contained in the interior escapes to the outside, and further heating the assembled package in the vacuum oven after the gas in the interior escapes to the outside and until the solder film re-melts and seals over the hole. | 03-08-2012 |
