For 25 years our de-lidder™ machines have been the industry's state of the art solution for removing lids from hermetic packages. Our systems are designed for cleanroom use, by cleanroom staff - not skilled machinists.
Our process uses special high-speed tooling, set up to machine through lid flanges from below. Particles are kept out of the package cavity by tool and lid geometry, gravity, and vacuum.
The photo at right shows a package wall after machining. The silvery side shows where a thin layer of nickel was melted between the package wall and lid flange. Our de-lidder™ machined through the lid flange right to this nickel, releasing the lid. The gold beside it surrounds the package cavity holding the circuit - note that the gold plating there is untouched - so it will hold the new lid at exactly the same height as the original.
During the reseal process, our machined surface tool marks help to spread nickel along the package wall, improving hermeticity - there is no need to sand the package after removing the lid, no extra cleaning.
