    摘要: Various sockets for packaged integrated circuits and methods of making the same are provided. In one aspect, a method of mounting a semiconductor chip is provided that includes providing a package that has a base substrate with a first side and a second side opposite the first side. The second side has a central region. The package includes a semiconductor chip and a lid coupled to the first side. A socket is provided for receiving the base substrate. The socket includes a mound that projects toward the second side of the base substrate when the base substrate is seated in the socket to provide support for the central region of the base substrate. The package is mounted in the socket. The mound provides support for the central region of the base substrate.

    摘要: A method and apparatus are provided for controllably dispensing flux on a substrate having a plurality of conductive terminals. Flux having a viscosity range between 10 centipoises and about 150 centipoises is sprayed on the substrate and the conductive terminals at a valve pressure range between about 1.5 psi and about 30 psi via a dispense nozzle of a flux dispenser. Upon a subsequent high temperature solder reflow process, the sprayed flux on the substrate is mostly removed by thermal decomposition to volatile species, thereby significantly reducing flux residue remaining on the surface of the substrate between the conductive terminals.

    摘要: A method of fabricating laminate assemblies determines the ideal weight (W) of underfill to be dispensed, based on the size of the semiconductor die and the gap between the die and the laminate substrate. Underfill is dispensed in a single step in an amount between 1.1W and 1.3W to form fillets that cover at least 15% of the height of the semiconductor die on all four sides of the die. The amount of underfill ensures that the fillet coverage imbalance is 30% or less for each of the pairs of opposing sides of the die, thereby improving solder joint reliability.

    摘要: A boat is formed with a plurality of through-holes sized to securely maintain ceramic or organic flip chip semiconductor packages in place during assembly. Embodiments comprises a boat having a bottom layer with an array of four-sided through-holes and a top layer with an array of through-holes and tabs extending from the sides of the through-hole. Embodiments further include a boat having a bottom layer with through-holes smaller than substantially aligned overlying through-holes in the top layer, the substantially aligned through-holes forming flip chip package holding pockets. An alignment mechanism ensures that components are accurately positioned on flip chip packages held in the boat during assembly.

    摘要: Detection of flux residue remaining the formation of a device/substrate assembly is carried out by contacting the assembly with a fixed amount of solvent adapted to remove residual flux from the assembly and measuring the conductivity or resistance of the contacted solvent to determine the presence of flux residue in the solvent obtained from the assembly. Embodiments include contacting the assembly with isopropanol by immersing and withdrawing the assembly in a fixed amount of the solvent and measuring the conductivity of the contacted solvent with a volt meter.
