    Abstract: Reliability is improved for the mechanical electrical connection formed between a grid array device, such as a pin grid array device (PGA) or a column grid array device (CGA), and a substrate such as a printed circuit board (PCB). Between adjacent PCB pads, a spacing pattern increases toward the periphery of the CGA, creating a misalignment between pads and columns. As part of the assembly method, columns align with the pads, resulting in column tilt that increases from the center to the periphery of the CGA. An advantage of this tilt is that it reduces the amount of contractions and expansions of columns during thermal cycling, thereby increasing the projected life of CGA. Another advantage of the method is that it reduces shear stress, further increasing the projected life of the CGA.

    Abstract: The present disclosure enhances the design flexibility of a multilayer electronic device. A multilayer electronic device is formed by alternately stacking, in a top-bottom direction, substrate layers in which substrates are disposed and a component layer in which at least one component is disposed. A non-superposing region in which a substrate of a first substrate layer positioned on the upper side of a first component layer is not superposed on a substrate of a second substrate layer positioned on the lower side of the first component layer, as viewed from above, is formed in the substrate. Accordingly, within the multilayer electronic device, a space in which the substrate of the second substrate layer is not located can be formed in a region under the non-superposing region of the substrate of the first substrate layer. By using this space, the design flexibility of the multilayer electronic device can be enhanced.

    Abstract: A printed circuit board, and a method of fabricating the printed circuit board is disclosed. The printed circuit board includes at least one coaxial via. A hollow via is disposed in the printed circuit board. A metal sleeve is formed around the circumference of said hollow via. An inner conductive path is disposed in the hollow via. Additionally, an insulating material is disposed in the hollow via, between the conducting path and the metal sleeve. The conductive path is used to connect signal traces disposed on two different layers of the printed circuit board. In some embodiments, these signal traces carry signals having a frequency above 1 GHz, although the disclosure is not limited to this embodiment.
