Abstract
A memory card has a housing including an interior chamber and a top metal cover. A substrate is located in the interior chamber and carries printed circuit leads, packaged semiconductor devices connected to selected printed circuit leads, and a connector connected to selected printed circuit leads. The packaged semiconductor devices are spaced from the top metal cover and a thermal coupler is located between the top metal cover and the packaged semiconductor devices for coupling heat generated by the packaged semiconductor devices to the top metal cover.
Claims7
A memory card, comprising:
- a housing including an interior chamber and a top metal cover;
- a substrate in said chamber, said substrate carrying printed circuit leads, packaged semiconductor devices connected to selected printed circuit leads, and a connector connected to selected printed circuit leads, said packaged semiconductor devices being spaced from said top metal cover, said substrate including a plated through hole connected to circuit ground and a flexible conductor soldered in said plated through hole and extending through said housing to contact said top metal cover;
- and
- a thermal coupler between said top metal cover and said packaged semiconductor devices for coupling heat generated by said packaged semiconductor devices to said top metal cover.
