摘要: A flux formulation includes an activator and a protic solvent. The activator may be glutaric acid, levulinic acid, 2-ketobutyric acid, 2-oxovaleric acid, or mixtures thereof. Suitable protic solvents include alkanediol, alkoxy propanol and alkoxy ethanol. The flux formulation may be a no-clean flux formulation that may be used in the soldering of electronic circuit board assemblies, for example, in conjunction with a support fixture having a planar back surface that minimizes vibrations during processing that might otherwise cause misalignment between a chip and a substrate prior to solder reflow.

摘要: Reflow Grid Array (RGA) technology may be implemented on an interposer device, where the interposer is placed between a motherboard and a ball grid array (BGA) package. The interposer may provide a controlled heat source to reflow solder between the interposer and the BGA package. A technical problem faced by an interposer using RGA technology is application of solder to the RGA interposer. Technical solutions described herein provide processes and equipment for application of solder and formation of solder balls to connect an RGA interposer to a BGA package.
