Embodiments of the present disclosure describe package alignment frames for a local reflow process to attach a semiconductor package to an interposer. The frame may comprise a two frame system. The interposer may be on a mounting table or on a circuit board. The frame may include a body with a rectangular opening dimensioned to receive a semiconductor package to be coupled to the interposer. The frame may be to align a ball grid array of the semiconductor package with pads of the interposer. A second frame may be to receive the first frame and may be to align a ball grid array of the interposer with pads of the circuit board. A single frame may be used to couple a semiconductor package to an interposer and to couple the interposer to a circuit board. Other embodiments may be described and/or claimed.

Disclosed herein are integrated circuit (IC) package support structures, and related systems, devices, and methods. In some embodiments, an IC package support structure may include a first heater trace, and a second heater trace, wherein the second heater trace is not conductively coupled to the first heater trace in the IC package support structure.

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.

Disclosed herein are integrated circuit (IC) packages with temperature sensor traces, and related systems, devices, and methods. In some embodiments, an IC package may include a package substrate and an IC die disposed on the package substrate, wherein the package substrate includes a temperature sensor trace, and an electrical resistance of the temperature sensor trace is representative of an equivalent temperature of the temperature sensor trace.
