Automotive Flex Harness

Bringing Electrical Distribution Systems to the 21st Century

CelLink’s circuits provide much greater control over
power and data transmission than traditional round wire
– at 1/4th the weight and 1/10th the volume.

Circuit construction

A typical CelLink wire harness circuit construction might include:

75-125 µm thick flame-retardant PEN, polypropylene, or LLDPE coverlay
70-125 µm thick copper or tin-plated copper conductor
75-125 µm thick flame-retardant PEN, polypropylene, or LLDPE coverlay

For high speed data transmission, 250 µm LLDPE or polypropylene layers and 35 µm copper shield layers may be included in the circuit construction for low-loss, impedance matched signal transmission.

Wiring Simplification

With over 2000 wires today’s high end vehicles, there is an urgent need for a simplification of the wiring systems in use today. To achieve this, CelLink’s flex harnesses may be directly soldered to controller PCBs to create a zone-based wiring architecture without increasing the terminal and connector content within the vehicle.

Volume and Weight Savings

CelLink’s circuits are particularly advantageous in regions of the vehicle where space is at a premium: areas such as the instrument cluster, headliner, front and rear fascia, and seats are a perfect fit for flex harnessing.

No matter where CelLink is used to replace round wire in the vehicle, a 60-75% harness weight reduction is likely to be achieved from the improved thermal performance of a flat wiring system and the elimination of ancillary materials like tape and clips.

Ease of Assembly

Through the use of patterned adhesive backings, CelLink circuits may be assembled to the vehicle frame quickly, reliably, and without need of mechanical fasteners and snaps – saving space and simplifying vehicle design.

Just-in-time, Automated Production

CelLink’s flex harnesses are made using automated equipment, enabling the production of wiring in the same geographic area as final vehicle assembly. This, along with CelLink’s tool-less process, significantly shortens automotive wiring supply chains.
