Cable Concept - 3D Printer Wiring Harness

- Aug 03, 2019-

Flexible Flat Cable, referred to as flexible cable or FFC, RFC. It is a new type of data cable that is pressed by high-tech automation equipment using PET or other insulating materials and extremely thin tin-plated flat copper wire. It has soft, random bending, thin thickness, small size, and connection. Simple, easy to disassemble, easy to solve electromagnetic shielding (EMI) and other advantages. The flexible flat cable is mainly divided into two ends: a round head (referred to as R-FFC for direct soldering) and a flat end (referred to as FFC for inserting a socket).

Among them, the 3D printer harness is most suitable for data transmission cables between mobile parts and motherboards, between boards to boards, and in miniaturized electrical equipment. It is widely used in the connection between various printer print heads and motherboards, signal transmission and board connection of plotters, scanners, copiers, stereos, LCD appliances, fax machines, various DVD players and other products. In modern electrical equipment, there is almost nowhere.

Since the cost of FFC cables is better than FPC (Flexible Printed Circuit), its application will become more widespread. In most places where FPC is used, FFC can basically be replaced.

The cable is small and lightweight, and the cable panel was originally designed to replace the larger wire harness. On current cutting-edge electronics assembly boards, the cable is usually the only solution to meet the miniaturization and mobility requirements. A cable (sometimes referred to as a flexible printed circuit) is a circuit that etches a copper circuit or a printed polymer thick film on a substrate of a polymer. For devices that are both thin and light and compact and complex, their design solutions range from single-sided conductive traces to complex multilayer 3D assembly. The total weight and volume of the cable is reduced by 70% compared to the conventional round wire harness method. The cable can also be increased in strength by using reinforcing materials or liners for additional mechanical stability.

The cable can be moved, bent, twisted without damaging the wire, and can be shaped to different shapes and special package sizes. Its only limitation is the volume space problem. Thanks to its ability to withstand millions of dynamic bends, the cable is well suited for continuous motion or regular motion in an interconnected system and is part of the final product function. Solder joints on rigid PCBs are subject to thermal mechanical stress and fail after hundreds of cycles. JEC, product manager at EECX, said: "Requires electrical signal/power movement, and some products with smaller form factor/package size benefit from cable."

The cable has excellent electrical properties, dielectric properties, and heat resistance. The lower dielectric constant allows for fast transmission of electrical signals; good thermal performance makes components easy to cool down; higher glass transition temperatures or melting points allow components to operate well at higher temperatures," said LT Electronic's CEO.

Cables have higher assembly reliability and quality. The cable reduces the hardware required for interconnection, such as solder joints, trunks, backplane lines and cables commonly used in conventional electronic packages, so that the cable can provide higher assembly reliability and quality. Because the traditional interconnected hardware composed of multiple complex systems is assembled, it is prone to high component misalignment rate. Ping.Wu, marketing manager of EECX Electronic Products Division, said: "The rigidity of the cable is low and the volume is small. It is precisely because the size of the components of the cable is small, so the materials used are less." With the advent of quality engineering A very thin flexible system is designed to be assembled in only one way, eliminating many of the human error typically associated with independent wiring engineering.
