摘要： A laser head for simultaneously attaching solder balls to a carrier has at least one solder tip, with the number of solder tips being equal to the number of solder balls to be attached to the carrier. Each solder tip is heated by an optical fiber in thermal contact with the tip at one end of the fiber and coupled to a laser, preferably operating in the infrared wavelength range, at the other end of the fiber via a multiplexer coupling device. A spring is used in association with each solder tip to bias each solder tip to hold the carrier in contact with the solder balls. The tip absorbs the radiant energy as it exits the optical fiber, and the tip is heated. The laser and multiplexer permit precise control over the heat imparted to the tip, which in turn permits control of the amount of the solder ball that is reflowed.

摘要： A heatsink is provided which can be removably secured in a heat transfer relationship to an electronic module or package by an epoxy type adhesive. A screw is provided through one end of the heatsink directly over an edge of the module sealing cap. To remove the heatsink from the module, the screw is turned down to contact the cap. Continued turning causes a prying force between the cap and the module whereby the heatsink is peeled away and removed from the module. All forces are directed between the cap and the module thereby eliminating harmful stress from being transmitted through the solder ball connections and to a supporting circuit card.

摘要： A low cost process for fabricating solder column interconnectons for an electronic package is described. The process includes the step of filling an array of pin holes in a pin mold with a lead/tin solder, which array of pin holes is in substantial registration with the array of conductive pads on one side of a chip carrier; heating the lead/tin solder in the pin mold such that the solder becomes molten and coalesces with the array of conductive pads of the chip carrier, thereby forming an array of miniature pins bonded to the array of conductive pads of the chip carrier; joining circuit components to the other side of the chip carrier; and reflowing an eutectic lead/tin solder paste screened to the corresponding array of conductive pads of a circuit board to bond the free ends of the array of miniature pins of the carrier to the corresponding array of conductive pads, thereby forming the solder column connnections between the chip carrier and the circuit board. The process is suitable for mass production of reliable, high-density electrical interconnections between a chip carrier and a supporting circuit board.
