    Abstract: A wiring substrate with reduced thermal expansion stress. A wiring substrate, such as a laminated PWB, thin film circuit, lead frame, or chip carrier accepts an integrated circuit, such as a die, a flip chip, or ball grid array package. The wiring substrate has a thermal expansion stress reduction insert, void, or constructive void in a thermal expansion stress region proximate to the integrated circuit. The thermal expansion stress reduction insert or void may extend a selected distance from the edge or edges of the integrated circuit attachment area. The thermal expansion stress reduction insert or void improves the flexibility of the wiring substrate in the region that is joined to the integrated circuit, thus reducing thermal stress between components of the wiring substrate-integrated circuit assembly. In another embodiment, layers of a laminated wiring substrate are intentionally not bonded beneath the chip attach area, thus allowing greater flexibility of the upper layer of the laminate.

    Abstract: A relatively thin expansion layer (18) is provided on top of the conventional printed wiring board (20). This expansion layer (18) is bonded to the printed wiring board (20) except at locations (40) underneath the footprint of the chip carrier (13) and solder joints (42). This expansion layer (18) provides forgivable expansion between the ceramic leadless chip carrier (13) and the printed wiring board (20) due to thermal expansion mismatch, to thereby reduce cracking of the solder joint (42). In an alternative embodiment, prevention of bonding underneath the chip carrier footprint is provided by a thin layer of polytetrafluoroethylene (PTFE) (39). Methods for applying the PTFE layer are disclosed.

    Abstract: A wiring substrate with reduced thermal expansion. A wiring substrate, such as a laminated PWB, thin film circuit, lead frame, or chip carrier accepts an integrated circuit, such as a die, a flip chip, or a BGA package. The wiring substrate has a thermal expansion reduction insert in a thermal expansion stress region where the integrated circuit is mounted. The thermal expansion reduction insert may extend a selected distance from the edge or edges of the integrated circuit attachment area, or stop a selected distance from the edge or edges of the integrated circuit attachment area, or be essentially equal to the integrated circuit attachment area. The thermal expansion reduction insert reduces the thermal (LMF) expansion of the wiring substrate in the region that is joined to the integrated circuit, thus reducing thermal stress between components of the wiring substrate-integrated circuit assembly. In a specific embodiment, the wiring substrate is a laminated printed wiring board with the thermal expansion reduction insert in a layer next to an outer layer to which the integrated circuit is joined (mounted). In a further embodiment the thermal stress reduction insert is a CIC insert or a copper-molybdenum insert. In an alternative embodiment, the wiring substrate is a thin film substrate or a VLSI substrate.
