Abstract: Methods, systems, and devices for providing computer implemented services are disclosed. To provide the computer implemented services, a data processing system may include hardware components that provide the computer implemented services. Any of the hardware components may have thermal limitations. To mitigate the impact of the thermal limitations, the data processing system may include host circuit card integrated heating assemblies. The heating assemblies may be used to warm hardware components of devices connected to the host circuit card. When connected to the host circuit card, a thermal conduction path between a device and a heating assembly may be established.

Abstract: A method for producing or disassembling an electronic assembly are provided. The assembly may have a heating device integrated into a substrate. The heating device can be heated via an external power supply during the assembly process so that, for example, solder connections of an electric component can be melted. The heating device can also be used when operating the electronic assembly, and the heating device can then be directly actuated by the component. For this purpose, an electric connection is then established between the component and the heating device, the connection not yet being provided during the thermal assembly process in order to protect the electronic components of the circuit from being damaged.

Abstract: A formed graphite sheet is shaped and sized as a protective shield positioned over an electronic component coupled to a PCB. The formed graphite sheet is used to protect a body of the electronic component from heat applied during the assembly of the electronic component to the PCB, such as the heating steps used in SMT and through-hole technology. The formed graphite sheet is shaped to selective direct impinging heat. The heat can be directly away from the entire electronic component. Alternatively, the heat can be selectively directed away from some portions of the electronic component and toward other portions of the electronic component.

Abstract: A printed circuit board set having high-efficiency heat dissipation includes a printed circuit board (PCB) and a heat dissipating device. The PCB has multiple electronic elements, at least one heat dissipating hole, and at least one thermally conductive material. The electronic elements are disposed on the top surface of the PCB. Each of the at least one heat dissipating hole is formed through the top and bottom surfaces of the PCB and aligns with one of the electronic elements. Each of the at least one thermally conductive material is disposed in the corresponding heat dissipating hole and in contact with the corresponding electronic element. The heat dissipating device is attached to the bottom surface of the PCB and in contact with the at least one thermally conductive material. With a high thermal conductivity, the at least one thermally conductive material rapidly transfers the waste heat produced by the PCB in operation to the heat dissipating device for heat dissipation.
