Examples
example 1
[0342] Example 1 - Forming a Hermetic LCP Package
[0343] Include 3850 and Alternating sheets of 3908 3 mm thick LCP laminate were machined into 28 x 20 x 3 mm open top shells with a continuous land around the opening. The internal dimensions of the housing are approximately 24 x 16 x 2 mm. Put two identical shells against each other so that the adjoining faces are aligned with each other, and then use the 50μm space between them 3908 layers, the two shells are heat-sealed together. The seal was created by heating the opposing shells to 290°C for 30 minutes, with spacers in heated jaws preventing excessive compression. The package thus formed was cooled to 80°C before removal from the heat sealer.
example 2
[0344] Example 2 - Forming a Hermetic LCP Package
[0345] Include 3850 and Alternating sheets of 3908 3 mm thick LCP laminate were machined into a 28 x 20 x 3 mm housing similar to Example 1 . But the abutment is bounded by an apex surrounding the top opening, wherein the apex is about 5 mm wide by about 1 mm thick. This provides a maximum external dimension of approximately 38x30x3mm. Put two identical shells facing each other, using the 50μm between them The 3908 layers are heat sealed together. The seal was created by heating the housing to 290° C. for 30 minutes, with spacers in heated jaws preventing excessive compression. The package thus formed was cooled to 80°C before removal from the heat sealer.
example 3
[0346] Hermeticity test of example 3-LCP package
[0347] A 0.5 mm diameter hole penetrating from the package body into the internal cavity was formed in the packages formed according to Examples 1 and 2 by drilling. The cavity is filled with approximately 0.7 ml of pure water or dry acetonitrile and the well is sealed by melting a small LCP plug. The filled packages were then tested for hermeticity by heating to 70° C. and measuring the weight loss after several weeks. No weight loss was measured, indicating that the resulting package has less than 1×10 -13 cm 3 .cm / cm 2 / s / Pa permeability, and for liquid acetonitrile, has less than 1×10 -10 cm 3 .cm / cm 2 / s permeability.
