Abstract: A vapor chamber device has a housing and multiple chambers. The housing includes two shells opposite to each other. The chambers are formed between the two shells. Each chamber contains a working fluid and has at least one diversion bump and a capillary structure. The diversion bump is formed on an inner surface of the second shell, and the capillary structure is mounted on the diversion bump. Since the chambers are independent from one another, when the vapor chamber device is vertically mounted to a heat source, the chambers at an upper portion of the vapor chamber device still contain the working fluid. The working fluid in the vapor chamber device may not all flow to a bottom of the vapor chamber device. Therefore, a contact area between the working fluid and the heat source is increased and heat dissipation efficiency is improved.

Abstract: A circuit board structure includes a first sub-circuit board, a second sub-circuit board, and a third sub-circuit board. The first sub-circuit board has an upper surface and a lower surface opposite to each other, and includes at least one first conductive through hole. The second sub-circuit board is disposed on the upper surface of the first sub-circuit board and includes at least one second conductive through hole. The third sub-circuit board is disposed on the lower surface of the first sub-circuit board and includes at least one third conductive through hole. At least two of the first conductive through hole, the second conductive through hole, and the third conductive through hole are alternately arranged in an axial direction perpendicular to an extending direction of the first sub-circuit board. The first, second and third sub-circuit boards are electrically connected to one another.

Abstract: A package structure includes a first substrate, a second substrate disposed on the first substrate, a third substrate disposed on the second substrate, and multiple chips mounted on the third substrate. A second coefficient of thermal expansion (CTE) of the second substrate is less than a first CTE of the first substrate. The third substrate includes a first sub-substrate, a second sub-substrate in the same level with the first sub-substrate, a third sub-substrate in the same level with the first sub-substrate. A CTE of the first sub-substrate, a CTE of the second sub-substrate, and a CTE of the third sub-substrate are less than the second CTE of the second substrate.
