HSIO Technologies has developed several interconnect technologies that enable very high speed, fine pitch separable interconnect between a semiconductor package, flex cable or printed circuit assembly and a system level printed circuit board. In basic terms, connector technology has been produced that allows of direct socketing of the SoC, PoP, CPU, RF Module or Memory device directly in a mobile platform in an ultra-low profile interface that also extends to a ganged RF capable interface for flex cable and board to board applications. The technology revolves around matching very small metallic contacts with fusion bonded Liquid Crystal Polymer materials to create a high speed interface on very fine pitch. Applications to be detailed are socketing of mobile processors, memory devices, and RF modules directly in a cell phone handset, tablet and notebook computer. Emerging complexity with mobile platforms dictates that traditional methods of validating platform performance is not adequate with significant value in the ability to plug packaged IC devices into the actual consumer platform to validate silicon and performance. The paper will document the package substrate to connector interface as well as introduce very high performance connector and flex cable interconnects on 0.35 mm pitch area array for mobile, desktop, and server applications.

Abstract Defense and Aerospace applications increasingly rely on commercial off-the shelf electronics. Electronics in defense applications may be exposed to harsh environments including high-g acceleration loads. The horizontal board configuration is most frequently tested. However, other shock orientations may be more damaging depending on technology and design. The out-of-plane displacement and strain values highly depend on the angle of shock on the electronic components in the printed circuit board. The effect of variation in drop angle under high G conditions, and efficacy of supplemental restraint mechanisms on the reliability have not been studied at high-g acceleration loads in the range of 10,000g–50,000g. In this study the reliability of fine-pitch electronics and large 3640 capacitors with C0G dielectric has been studied in presence of potting compounds, different shock orientations. A circular printed circuit board has been designed with daisy-chained packages. The drop angle has been varied from zero-degree to 30-degree. A drop-tower with dual mass shock amplifier has been used to achieve the desired acceleration pulse. Transient dynamic deformation has been measured using high-speed imaging in conjunction with digital image correlation.

Empty substrate integrated coaxial line (ESICL) technology preserves the many advantages of the substrate integrated technology waveguides, such as low cost, low profile, or integration in a printed circuit board (PCB); in addition, ESICL is non-dispersive and has low radiation. To date, only two transitions have been proposed in the literature that connect the ESICL to classical planar lines such as grounded coplanar and microstrip. In both transitions, the feeding planar lines and the ESICL are built in the same substrate layer and they are based on transformed structures in the planar line, which must be in the central layer of the ESICL. These transitions also combine a lot of metallized and non-metallized parts, which increases the complexity of the manufacturing process. In this work, a new through-wire microstrip-to-ESICL transition is proposed. The feeding lines and the ESICL are implemented in different layers, so that the height of the ESICL can be independently chosen. In addition, it is a highly compact transition that does not require a transformer and can be freely rotated in its plane. This simplicity provides a high degree of versatility in the design phase, where there are only four variables that control the performance of the transition.

Many applications in Power communication system have a demand of adjustable transmission time delay of high-speed signal. In sequential logic circuit, the control of transmission time delay of high-speed signal can effectively improve the accuracy of clock sampling, as a result, satisfy the constraints between clock signal and periodic data. A method of equivalent sampling based on printed circuit board (PCB) is provided in the article, it realizes equivalent sampling of the data by fixing a group of clock signal delay, thus, increase the accuracy of sampling.
