TLDR
In this article, an inexpensive doubled heat sink in extruded aluminum forms the base of the enclosure and the electronics are inserted into one part and is enclosed by a complementary shielding surface.Abstract:
A new concept for shielded enclosures of electronics is presented in this paper. An inexpensive doubled heat sink in extruded aluminum forms the base of the enclosure. The electronics are inserted into one part and is enclosed by a complementary shielding surface. The outer heat sink is cooled by forced ventilation. As openings are made redundant, seams between the parts of the enclosure are the only path for significant electromagnetic emissions. EMC-issues are also addressed in this paper; seams are modeled and simulated as short wave guides intercepted by screw joints. The simulations were carried out in CST Microwave Studio.read more

Development of Chip-on-Dot flip chip technique utilizing Gold Dot/sup TM/ flexible circuitry
TL;DR: Chip-on-Dot as discussed by the authors is a flip chip assembly technique for assembling chips which does not mandate either under-bump metallization (UBM) treatment to the aluminum input/output pads or die bumping.
