    摘要: The quality of soldering produced on devices such as printed circuit boards and multichip modules is significantly improved through use of a specific size distribution of solder particles. In particular, the solder includes a vehicle and solder particles of specific size. In general, an appropriate distribution of both large and small particles should be employed. Through this expedient short circuits and soldering defects in fine line devices are reduced.

    摘要: The specification describes a multi-chip IC package in which IC chips are flip-chip bonded to both sides of a flexible substrate. The upper (or lower) surface of the flexible substrate is bonded to a rigid support substrate with openings in the support substrate to accommodate the IC chips bonded to the upper (or lower) surface of the flexible substrate. In a preferred embodiment a plurality of IC memory chips are mounted on one side of the flexible substrate and one or more logic chips to the other. A very thin flexible substrate is used to optimize the length of through hole interconnections between the memory and logic devices. If logic chips are flip-chip mounted in the cavity formed by the openings, a heat sink plate can be used to both cap the cavity and make effective thermal contact the backside of the logic chips.

    摘要: The specification describes packaging assemblies for micro-electronic machined mechanical systems (MEMS). The MEMS devices in these package assemblies are based on silicon MEMS devices on a silicon support and the MEMS devices and the silicon support are mechanically isolated from foreign materials. Foreign materials pose the potential for differential thermal expansion that deleteriously affects optical alignment in the MEMS devices. In a preferred embodiment the MEMS devices are enclosed in an all-silicon chamber. Mechanical isolation is also aided by using a pin contact array for interconnecting the silicon support substrate for the MEMS devices to the next interconnect level. The use of the pin contact array also allows the MEMS devices to be easily demountable for replacement or repair.

    摘要: The specification describes a recessed chip IC package in which the IC chip is bonded to a silicon translator, and power and ground planes for IC power and ground interconnections are formed on separate interconnect levels of the translator. The multilevel interconnection capability of the translator allows crossovers, and allows power and ground pins from the IC chip to be both isolated from signal I/Os, and consolidated into fewer interconnections going to the next board level. The thermal mismatch between the silicon translator and conventional printed wiring board materials is addressed by using an interposer which is essentially a ball grid array of plated-through holes that transfers the interconnect pattern from the translator to the printed wiring board. The interposer may have a composition with a coefficient of thermal expansion (CTE) that lies between the CTE of silicon and the CTE of the board material. It may also be provided with holes or slots for additional stress relief.
