    Abstract: A semiconductor chip package structure for providing a reliable interface between a semiconductor chip and a PWB to accommodate for the thermal coefficient of expansion mismatch therebetween. The interface between a chip and a PWB is comprised of a package substrate having a plurality of compliant pads defining channels therebetween. The package substrate is typically comprised of a flexible dielectric sheet that has leads and terminals on at least one surface thereof. The pads have a first coefficient of thermal expansion (“CTE”) and are comprised of a material having a fairly low modulus of elasticity. An encapsulant having a second CTE lower than the CTE of the compliant pads is disposed within the channels to form a uniform encapsulation layer. The pads are in rough alignment with the conductive terminals on the package substrate thereby allowing independent movement of the terminals during thermal cycling of the chip. The encapsulant encases the conductive leads electrically connecting the terminals to chip contacts on a face surface of the chip. The lower CTE of the encapsulant controls the flexing of the conductive leads so that the leads do not prematurely fatigue and become unreliable while the lower modulus compliant pads relieve the stress on the solder balls induced by the CTE mismatch of the chip and the PWB.

    Abstract: A printed circuit board has a plastic carrier plate and a one-piece pressed screen forming interconnects of the electrical circuit that are firmly mechanically connected to one another via preferably hot-stamped or ultrasound-deformed plastic webs. The interconnects have connector tabs bent off at a right angle and contact tabs for contacting the plug-in base and the relays to be accepted and also have stamped-out contact profiles for the connection to electrical components. The plugged-on relays and components are preferably connected to the interconnects welding. A two-sided access to parting locations in the pressed screen is made for tools on the basis of recesses in the carrier plate.

    Abstract: A method of making a multiple part compliant interface for a microelectronic package including the steps of providing a first microelectronic element having electrically conductive parts, providing an array of curable elastomer support pads in contact with the first microelectronic element, curing the curable elastomer support pads while the support pads remain in contact with the first microelectronic element and providing an array of adhesive pads in contact with the support pads, whereby each adhesive pad is disposed over and in substantial alignment with one of the support pads. A second microelectronic element having electrically conductive parts is then assembled in contact with the array of adhesive pads by abutting the second microelectronic element against the array of adhesive pads and compressing the adhesive pads and support pads between the first and second microelectronic elements. The array of adhesive pads are then cured and the electrically conductive parts of the first and second microelectronic elements are interconnected. The array of support pads define channels running between any two adjacent support pads. A flowable curable elastomer encapsulant may be disposed within the channels after the electrically connecting step. Preferably, the support pads, adhesive pads and the encapsulant comprise substantially similar materials, such as silicone, in order to avoid problems associated with thermal cycling, such as air entrapment and/or voiding.
