Depending on the signal pin out, lay out and routing of board traces, the pin assignments can be different on each connector in the harness assembly. Two different types of pin out configurations are offered in I-PEX High Speed Harness Assemblies i.e. 1-N type straight pin out and 1-1 type mirror pin out configurations for routing and placement flexibility in designs.  For example pin 1 on…

Insertion Loss, Return Loss and VSWR are key performance indicators of High Speed Twinaxial and Micro-Coaxial Cable Assemblies. A high performance micro-coaxial cable results in excellent signal integrity and reduced losses in high speed applications. At I-PEX we take pride to offer the high performance CABLINE micro-coaxial and twinaxial cable assemblies which are built by using automated…

Four different types of Outer Tapes or Jackets are offered for High Speed Cable Harnesses for increased routing and placement flexibility in designs.  In Type 1 multipoint bundle style, Acetate Cloth type or Heat Shrinkable Tube Tape is wrapped around the cables at multiple points bundling the cables only at certain sections as shown in Figure 1 below : Figure 1. Type 1 Jacket/ Braid Style   …

It is important to consider the bending and flexing properties of high frequency micro-coaxial and twinaxial cable assemblies, when designed into new smaller, compact portable electronics. Both micro-coaxial and twinaxial cables are specified for Minimum Bend Radius, a parameter that determines how tightly these cables can be bent repeatedly with out being damaged and still ensuring high signal…

Number of channels in interface, required pin count, spacing between each pin, allowed mated width, length and profile height of plug and connector determine the type of connector that should be used. Maximum available area and location of connector on PCB also determines the mounting configuration for receptacle and plug harness assembly, which can be horizontal, right angle or vertical . I-PEX…

A twinaxial  cable has two center conductors typically used for differential signals. The two conductors are separated and surrounded by insualator like rubber or plastic. There is outer layer of dielectric around these conductors for insulation just like in Micro-coaxial cables. There is metallic outer conducting shield for ground return current and outer jacket. Twinaxial cables are more…

High frequency signals are more sensitive to electromagnetic interference (EMI) from near by communication sources like antennas, high speed board traces and transcievers on PCBs. By using micro-coaxial cables, these high speed signals are well shielded from noise and signal integrity of data is preserved. A micro-coaxial cable includes a center conductor for signal transmission that is…

Data rates play a critical role in today's smaller and faster electronic systems. It is important to maintain the high data rate for signals going between multiple printed circuit boards, when stacked in high density, compact devices for optimal performance. Data rates are typically determined by maximum operating frequency and are specified in Gbps. NOVASTACK®  series of products can support…

As the data rates increase and devices become smaller, the high speed signals are placed in close proximity of each other and the probability of signal interference increases. Objective of effective shielding in high performance board to board connectors is to minimize this unwanted signal from components near by, interfering with the desired signal in connector  and also to keep most of the…

NOVASTACK® series connectors are available in pin counts ranging from 10 pins to 70 pins with pin pitch as small as 0.35 mm. These ultra small, light weight connectors facilitate modern, compact portable systems with out compromising the connectivity, where every square mm and every mg matters. Availability of multiple stack up heights from 0.6 mm up to 1.5 mm typical provides design flexibility…

As modern electronics become smaller, the printed circuit boards inside the devices become highly populated with higher density than ever before. It has become more critical to deliver high power signals reliably alongside the high speed signals in a compact footprint between multiple boards without compromising the system performance. NOVASTACK® series connectors are offered in hybrid signal and…

Using Board-to-Board connectors with varying profile heights provides designers with the flexibility to optimize performance, reliability, and space efficiency in complex multi-board systems. Design flexibility, improved air flow and thermal management, reduced mating/demating interference, efficient use of space for lower EMI, enhanced mechanical stability, scalability of systems and support for…

 I-PEX offers the break out test boards for NOVASTACK® series connectors to measure the signal integrity performance of complete interconnect assemblies including the FPC itself or just for the plug and receptacle only. There are two types of test boards. i.e. the plug break out board and receptacle break out board.  Each board has either plug or receptacle mounted on one side of the board and 2…
