摘要： A method of making an electronic package. The method includes forming a semiconductor chip and an multi-layered interconnect structure. The semiconductor chip includes a plurality of contact members on one of its surfaces that are connected to the multi-layered interconnect structure by a plurality of solder connections. The formed multi-layered interconnect structure is adapted for electrically interconnecting the semiconductor chip to a circuitized substrate (eg., circuit board) with another plurality of solder connections and includes a thermally conductive layer being comprised of a material having a selected thickness and coefficient of thermal expansion to substantially prevent failure of the solder connections between said first plurality of electrically conductive members and the semiconductor chip. The method forms the electronic package to further include a dielectric material having an effective modulus to assure sufficient compliancy of the multi-layered interconnect structure during operation.

摘要： An electrical structure, and associated method of fabrication, for reducing thermally induced strain in a soldered interface, such as a solder ball or a solder column, between a chip carrier (or chip) and an electronic carrier such as a circuit card. The thermally induced strain may be caused during thermal cycling by a mismatch in coefficient of thermal expansion (CTE), and consequent differential rates in thermal expansion, between the chip carrier (or chip) and the electronic carrier. The thermally induced strain may also exist with a large chip carrier characterized by a large temperature difference during thermal transients between the electronic carrier and localized regions of the chip carrier, even in the absence of a CTE mismatch. The electrical structure of the present invention includes an interposing compliant layer of soft and spongy material between the chip carrier (or chip) and the electronic carrier. Thermal strains resulting from the differential rates of thermal expansion are diverted from the soldered interface into small motions of material within the compliant layer.

摘要： A method and structure for reducing thermally induced strains on the solder joints that couple a ball grid array (BGA) module to a circuit card, so as to improve the fatigue life of the BGA module. The thermally induced strains arise from a mismatch in thermal expansion coefficient between the dielectric substrate of the BGA module and the dielectric board of the circuit card. The method generates void annular regions around portions of the BGA dielectric substrate to which the BGA solder balls are to be attached and/or around portions of the circuit card dielectric material to which the BGA module is to be attached. This results in the formation of dielectric islands or peninsulas that bound the solder balls of the BGA module after installation on the circuit card. The dielectric islands or peninsulas thus formed serve to increase the effective height over which the differential expansion is accommodated, thereby reducing the strains throughout the solder joints. Additionally, the void annular regions provide space for the deformation of the dielectric islands or peninsulas, thereby increasing their compliance and transferring strain from the solder joints to the dielectric islands or peninsulas.
摘要翻译：一种用于减少将球栅阵列（BGA）模块耦合到电路卡的焊点上的热诱导应变的方法和结构，以提高BGA模块的疲劳寿命。热诱导的应变来自BGA模块的电介质基板和电路卡的电介质板之间的热膨胀系数的不匹配。该方法在BGA电介质基板周围产生空隙环形区域，BGA电介质基板将附着BGA焊球和/或围绕BGA模块所要连接的电路卡电介质材料的周围。这导致在安装在电路卡上之后形成结合BGA模块的焊球的电介质岛或半岛。这样形成的电介质岛或半岛用于增加容纳差动膨胀的有效高度，从而减少整个焊点的应变。此外，空隙环形区域为介质岛或半岛的变形提供了空间，从而增加了它们的顺应性并将应变从焊点传递到电介质岛或半岛。

摘要： A method and associated structure for excising laminate chip carriers from a panel that has a thickness less than about 100 mils. A laser beam is focused on a surface of the panel, and the panel is moved relative to the laser beam in a geometric pattern, such that cells of the panel (e.g., chip carriers) are excised from the panel. The laser parameters include a wavelength between about 500 nanometers and about 600 nanometers, a pulse width greater than about 100 nanoseconds and less than about 350 nanoseconds, an average power of at least about 1 watt, a pulse repetition rate between about 5,000 pulses/sec and about 20,000 pulses/sec, and a target diameter (D) between about 2 microns and about 30 microns. The kerf width between adjacent excised cells is between about 2 microns and about 75 microns. The width of an excised cell is at least 5 mm. A displacement between successive pulses of the laser beam is less than about 2D. The panel may comprise a layered structure that includes an organic layer and a metal layer. The laser includes, inter alia, a lasant of Nd:YAG, Nd:YLF, Nd:YAP, or Nd:YVO4. The method of the present invention wastes less panel area by at least a factor of about 13 than does the mechanical excising techniques of the related art.
