This white paper introduces the CABLINE^® series connectors, specifically the dual-row connectors CABLINE^®-CX II, CABLINE^®-UX II and CABLINE^®-UA II. It focuses and discusses on the different pin-out selection and PCB breakouts to overcome some of the challenges that are presented with dual-row connectors.

"Empty-closure", a common occurrence in manufacturing and assembly, is the operation of an actuator without inserting an FPC into the connector. It can cause connector damage or incomplete mating when the FPC is subsequently inserted. This white paper introduces the "empty-closure" issue by using I-PEX's MINIFLEX^® series as an example, and how it is addressed, as well as the design know-how gained through analysis and calculation to ensure that the connector will function even if an empty closure occurs.

The mediums over which electrical signals travel can either help or hurt the electromagnetic compatibility of a system. Common mediums include printed circuit board (PCB) traces, interconnects, and cables. In order to see how intrapair skew induces EMI, EMI must first be defined.

A paddle card can be mated with a mating connector, and PCB or FPC can be designed for the plug circuit. Paddle cards are easy to add to ground structures, improving ground return. Impedance matching is simplified, and signal integrity is improved at higher frequencies.
