Patent number: 11228123Abstract: A cable assembly comprising a connector with a termination that enables high density and high signal integrity. Shields of cables are terminated to a paddle card via a conductive structure attached to a surface of the paddle card. The signal conductors of the cables are terminated to pads on the paddle card that are exposed within openings of the conductive structure. Such a structure creates a ground structure per cable that provides low insertion loss and low crosstalk, even when multiple cables are aligned side by side and terminated in one or more rows. The cables may be drainless, enabling a large number of cables, such as eight cables, to be packed within the width of a paddle card specified in high density standards such as QSFP-DD or OSFP. The cables may nonetheless have large diameter signal conductors, enabling 2.5 or 3 meter assemblies with less than 17 dB insertion loss.Type: GrantFiled: December 16, 2019Date of Patent: January 18, 2022Assignee: Amphenol CorporationInventors: Mark M.

Patent number: 11212912Abstract: Voids are introduced in a copper shape to reduce warpage experienced by a printed circuit board during a reflow process. Copper shapes on an outer layer of a printed circuit board may be used to connect large packages that include ball grid arrays to the printed circuit board. The copper shapes may induce warpage in the printed circuit board during the reflow process. Routing a mesh pattern of voids in the copper shapes may reduce solder ball joint cracking and pad cratering during reflow and make solder joints more reliable. The voids may make the copper shapes less ridged and change the copper heat dissipation profile to remove sharp warpage forces that cause solder joints to experience pad cratering. The voids may be 8 mil×8 mil cuts or indentations in the copper shape.Type: GrantFiled: June 30, 2020Date of Patent: December 28, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Benito Joseph Rodriguez, Shu-Ming Chang, Dillip Kumar Dash, Po Chun Yang, Juan-Yi Wu
