Abstract
The present invention is directed to electronic components shielded from electromagnetic interference through the use of conforming shield enclosures. Conforming shield enclosures are flexible metalized thermoformed thin-wall polycarbonate polymer film substrates used to shield a radiation source. The present invention relates to conforming shielded forms for electronic component assemblies and specifically to electronic component assemblies which are shielded to protect against electromagnetic and radiofrequency interference. Specifically, the shielded electronic component assembly comprises (a) a semiconductor device to be shielded from electromagnetic frequencies; (b) a reference potential source; (c) a housing enclosing the semiconductor device within the assembly; and (d) a conforming shield enclosure electrically connected to the reference potential source. The conforming shield enclosure comprises a flexible, metalized thermoformable polymer having dimensions conforming to the inside of the housing and enclosing and thereby shielding the semiconductor device from electromagnetic frequencies. The conforming shield enclosure is prepared by paint metalization.
