FPC assemblies with hi-rel connectors allow for dense packing
To allow PCBs to be more densely packed together, Harwin now offers both its Datamate J-Tek and Gecko high-reliability (Hi-Rel) connectors with flexible printed circuits (FPCs) attached. They are designed for where there is little space above the board surface, for example in aerospace, motorsport, satellite and defence installations.
The FPC assemblies provide engineers with lower profile interconnection that facilitate PCBs within a system design able to be stacked closer together than is typically possible. Right-angled connections mean that they can be kept at the periphery of the board for thermal management and ease of mating.
The Datamate J-Tek option consists of a 2mm-pitch connector and a 1A-rated 1mm-pitch FPC. It is supplied in a single-ended design fitted with a male connector. The Gecko options have a 1.25mm-pitch connector along with a 0.4A-rated 0.5mm-pitch FPC, available in single- or double-ended configurations. Standard 10-contact assemblies are supplied from stock, with other assemblies available on request.
The FPCs feature a copper-clad polyimide base with a bonded overlay. There is a rigid area at each end to aid connector mounting. According to Harwin, they are able to support a much tighter bend radius than conventional cables and are also better suited to dynamic movement when bent. The beryllium copper contacts use a four-finger design. The assemblies exhibit strong resilience to shock (up to 100G) and vibrational forces (up to 20G), without breaks in signal. There are stainless steel jackscrews on the Datamate connectors and sturdy latches on the Gecko connectors ensure interconnect integrity.
The Harwin FPC assemblies have an operational temperature range matching the relevant connectors, up to 65 to +150 degrees C.
The free ends of the FPC are compatible with industry standard FPC/FFC connectors that accept 0.3mm thickness circuits.
Harwin produces high reliability interconnect products for defence, aerospace, space, industrial, oil/gas and motorsport sectors.
Its portfolio includes the Gecko (1.25mm pitch), Datamate (2mm pitch), Mix-Tek (combined signal, power and coax) and high temperature M300 (3mm pitch) product lines. In addition, the company offers easy-to-implement EMI/RFI shielding solutions, a comprehensive portfolio PCB hardware (spacers, links, bridges, terminals, test points, etc.) and a broad range of industry standard connectors. All these products are available with short lead times via its extensive sales and distribution network.
Harwin’s global reach enables it to respond rapidly to customer needs, with sales offices and manufacturing facilities in the UK, the USA, Germany, France and Singapore.
