Abstract
An electronic device assembly (11) includes a heat dissipating substrate (18) having a seat (16). A device (14) is uniformly spaced from a base surface of the seat (16), and a layer of solder of uniform thickness occupies a gap between the surface of the seat and the device. Leads (31) and (33) extend at a shallow, acute angle from the device. A lead (32) is mounted to a support (28) extending from the substrate (18). Inner portions of the leads (31, 32, 33), the device (14) and portions of the substrate (18), are encased by an envelope (22), while outer portions (67) of the leads and a mounting tab (19) of the substrate extend from the envelope.
