Chapter One:Understanding a Ribbon Cable
What is a ribbon cable?
Another name for ribbon cable is multi-wire planar cable or hippie cables. It is a cable type that possesses lots of conducting wire that runs parallel to each other on the same flat plane.
The ribbon cable is flat and rectangular. The flexibility of the ribbon cable makes it easy to hold many connectors at the same time, as well as also transmitting a large amount of data through signals. Furthermore, ribbon cables help to manage conductors effectively, even where space is limited.
A typical instance that proves the usefulness of ribbon cable is its function in the computer hardware. The ribbon cable plays an important role in connecting the disk drive to the disk drive controller.
These cable types are specialised cables that are important in connecting IDE surfaces for IDE connectors.
Ribbon cable colour coding
The essence of ribbon cable colour coding is to prevent the occurrence of reverse connections. One rule for ribbon cable colour coding is that the edge of the cable which bears a red stripe connects to pin 1 of the connector. The cable colour coding makes it easy to identify the different set of connectors.
More importantly, it helps make the installation easier because it is easy to identify the different conductors that are important to the connection.
Ribbon cable size
A pertinent question that engulfs individuals mind is the exact size of the ribbon cable that suits their needs. There are two ways of identifying ribbon cable sizes. The two factors considered are:
• The pitch or spacing of conductors
• The number of conductors or ways.
For the pitch or spacing of the conductors is a spacing of 0.05 inch (1.27 mm) is the most common form of ribbon cable spacing. This spacing type allows for a two- row connector with a pin spacing of 0.1 inches (2.54mm). Most personal computers favour this exact spacing ribbon cable size. It is a common type of ribbon cable size in floppy disk drive cable and custom parallel ATA cables.
Other types of ribbon cable connectors’ size are 4, 6, 8, 9, 10, 14, 15, 16, 18, 20, 24, 25, 26, 34, 37, 40, 50, 60, 64 and 80.
Ribbon cables are unarguably very useful and play significant functions in printers and computers.
Chapter Two:Application of Ribbon Cable
Ribbon cables are almost indispensable in manufacturing industries. They play a significant role in consumer electronics manufacturing industries.
Additionally, ribbon cables are essential in building many electrical products. A good number of electrical products make use of ribbon cables. It is because of the miniature nature of ribbon cables, which makes it easy to use for designing electrical products.
Quite several manufacturers rely on Flat flexible cable(FFC) to build laptops and mobile phones.
More so, ribbon cables are important for the military- based equipment constructions. They are also important in industrial environments.
These cables are necessary for the automotive industry. In constructing automobiles, manufacturers make use of ribbon cables.
Industries like aviation industries and space exploration find the ribbon cables very essential in carrying out their activities.
Chapter Three:Ribbon Cable Connectors
There are quite a handful of ribbon cable connectors that are available with IDC termination. They are:
BT 224 connector
Another name for BT 224 connector is IDC connector. A lot of standards such as BS 9525- F0023, DIN 41651, and MIL-C- 83505 define this connector type.
• BT 224 connectors mate with either a purpose made plug or two-row gird of header pins with 0.1 inch 2.44mm spacing.
• They are compatible with ATA cables.
D- Subminiature connector
These connectors are not as common as the crimp and solder bucket types.
• D- Subminiature connectors are suitable for serial ports and printer ports. It means that these connectors work perfectly for both printers and serial ports.
DIN 41612 connector
It is a connector type that is very common among different suppliers that operate together. Although, the standard is now in an internationally standard form of IEC 60603-2 and EN 60603-2
• The DIN 41612 connector suits Euro card bus, NU bus, Futurebus, VMEbus, Multibus 11 and Tram motherboards.
• All of the applications of DIN 41612 use male Eurocard bus in a female DIN 41612 on a backplane.
PCB transition headers
PCB represents the Printed circuit board. It is a connector type with two rolls of pins with the same spacing as BT 224 connectors. For efficiency, these pins connect directly to the PCB.
This connector possesses high low contact resistance and long life. It also offers a cost-effective means of connecting PCB to other applications.
• It connects the wire to board
• It is also effective for separable header/sockets
• It is suitable for dual- in-line application
Micro Ribbon connector
There are a host of names for the ribbon connectors. These names are a telco, 25 pair, miniature delta ribbon, mini D ribbon, MDR, Amphenol or even miniature ribbon connector. Microribbon connector possesses a shape similar to D- Subminiature connector with two parallel rows of contact. Its contacts are not pins. Rather, they are small bands of metal in the form of ribbons.
The female connectors of the micro ribbon connector possess bail lock that connects it to the male counterpart for a secure connection.
• The micro ribbon connectors are a suitable fit for telecommunication equipment.
• It is also important for computers with a lot of contacts.
What are DIL headers?
The DIL headers possess pins with the same spacing as standard DIL ICs. They connect two Printed circuit Boards. Also, they work well with appropriate DIL socket to form a plug and even socket pair.
• These connectors work well within replacing an IC in connection to an external device.
• It is also suitable as a PCB transition header on stripboards.
Chapter Four:FFC (Flexible Flat Cable)
What are flexible flat cables?
Flexible flat cables are a type of ribbon cables that are flat and flexible. It is a thin flat cable commonly found in high-density electronics application. These are direct connections without any additional components. Its material is very flexible.
Flexible flat cables are a smaller form of ribbon cables. These cables possess a special sort of makeup. Its makeup is a flat and flexible plastic film base and multiple conductors on a surface.
• Flexible flat cables are important for easy cable management in high flex environments.
• It is a suitable cable for printers, scanners, copiers, fax machines, DVD stereos, LCD appliances and other electrical products.
• It is common in modern equipment
• It assists the printer connection between the head and the motherboard.
• The FFC plays a considerable role in signal transmission and plate board connections.
Benefits of Flexible Flat Cable
• The wires of a flexible flat cable are not wound like a round cable. It makes it easy to protect the individual wires.
• They are lighter and more flexible.
• They do not occupy too many spaces like round cables
• It offers a more sophisticated EMI/ RFI suspension. As such, it eliminates wire coupling issues.
• The ends of flexible flat cables are thick.
Ribbon cable VS FFC
Both cable types are important in diverse ways. While one assist in a particular field, the other remains relevant in a field that suits it. Though the flat cables were in existence long before the ribbon cables came into existence.
Ribbon cables are however efficient in various areas like computing, aerospace, military and robotics. These cables possess good superior quality, flexibility, packaging efficiency and reduce the presence of electronic noise. In spite of these numerous advantages, the ribbon cables handle termination techniques rather poorly.
More so, there are also worrisome cases of frictional heat in the cable during its repetitive motion cycles — also, conductors inside the cable move relative to one another.
Whereas, the flexible flat cables don’t move within the jacket so that it retains its electrical properties and qualities. Another interesting feature of the flexible flat cable is that the conductors of the cable have similar physical and electrical length.
Inflexible flat cables, the conductors are isolated to keep them stable. These cables are more flexible than ribbon cables.
FFC performs better than ribbon cables in terms of factors such as heat, weight, volume efficiencies and signal considerations.
Therefore, it is necessary to understand the capabilities of both the ribbon cable and flexible flat cables to ensure proper usage. In all, the flexible flat cables possess better features than ribbon cables.

Chapter Five:How to Choose Ribbon Cable
Asides recognising ribbon cables, the confusion lies in choosing them. In choosing ribbon cables, there are quite several factors to put into consideration. These cables are:
Pitch is spacing. It refers to the spacing of conductors within the ribbon cable. Pitch depends on the cable requirements and specifications. Some examples of pitches include 0.5mm, 1mm, 1.25mm, 2mm.
Ribbon cable pitch VS connector pitch
The ribbon cable pitch of the connector and that of a ribbon cable is never the same. The ribbon cable is always half of the connector pitch. By this implication, when there is a two-row connector pitch, the ribbon cable pitch is usually half of the connector’s pitch.
Another way of determining the pitch of the ribbon cable is by measuring outside edge of the cable and then divide the figure by the total number of connectors.
Ribbon cables tolerate all sorts of temperatures be it harsh or friendly. But, if ribbon cables are to operate perfectly in unfavourable temperatures, a silicon jacket is the best bet.
In choosing ribbon cables, flexibility is a necessary factor. Since ribbon cables are flexible, there is still a need to purchase a more flexible type if need be. In cases where the design is of limited space or requires a more flexible type, purchase a custom ribbon cable with greater flexibility that suits the job.
Put into consideration the life span of the ribbon cable you intend to purchase. Like every other electrical component, it is necessary to choose a ribbon cable that can survive the test of time. Choose a ribbon cable that is adequately proven by professionals and also assured of a long life cycle.
Fire resistant is another factor to consider when choosing a ribbon cable. The importance is not only for the benefits of the electrical equipment but also for safety too. Make it a point of duty to settle for a ribbon cable type that is in line with the EU’s Restriction of Hazardous Substances Directives and also fit according to fire safety standards.
