You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 35.175.0.0/16 has been blocked (disabled) by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:20, 2 March 2025.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

'''Flat Flexible Cable''' ('''FFC''') refers to any variety of electrical cable that is both flat and flexible, with flat solid conductors.  A flexible flat cable is a type of [[flexible electronics]]. However, the term FFC usually refers to the extremely thin flat cable often found in high-density electronic applications like laptops and cell phones.

==Overview==
Sometimes the term FPC ([[flexible electronics|flexible printed circuit]]) is even—somewhat inaccurately—used for any type of FFC;((Citation needed|date=April 2011)) however, this is more accurately used to describe [[Etching|etched]] or printed circuits that incorporate components and are built onto a flexible material. FFCs are usually straight connections without any components.

FFC is a miniaturized form of [[ribbon cable]], which is also flat and flexible. The cable usually consists of a flat, flexible plastic film base with multiple flat metallic conductors bonded to one surface. Often, each end of the cable is reinforced with a stiffener to make insertion easier or to provide strain relief. The stiffener makes the end of the cable slightly thicker.

Flexible flat cables are used instead of round cables for easy cable management, especially in high-flex applications. They usually take up less space than round cables, often offering better EMI/RFI suppression and eliminating wire-coupling issues. In addition, because the wires are protected individually and not wrapped many times over by different materials as round cables are, they are lighter in weight and offer greater flexibility.<ref>((cite web| url=http://www.wireandcabletips.com/introduction-flat-cables/| title=An introduction to flat cables| work=Wire & Cable Tips))</ref>

==Specifications==
; Number of Conductors (Pins): This is the total number of conductors within the cable, ranging from just a few to over 100. The conductors are also referred to as "pins." For example, an FFC cable with 20 conductors is called a 20-pin.

; Pitch: The spacing of the conductors.  The pitch typically refers to the distance from the center of one conductor to the center of its neighboring conductor.  A single FFC can have different pitches between different conductors on the same cable, however, this is uncommon.  FFC cables are available in many pitches, such as 0.500 mm, 0.625 mm, 0.635 mm, 0.800 mm, 1.00 mm, 1.25 mm, 1.27 mm, 2.00 mm, 2.54 mm, but the most common pitches are 0.500 mm, 1.00 mm, and 1.25 mm. Custom Pitch and Multiple Pitch FFC are available upon special request.

; Type: Some cables (described as Type 1 by Würth Elektronik or Type A by Molex) have exposed contacts on the same side at each end. Other cables (labelled Type 2 or Type D) have the exposed contacts on opposite sides of the cable (so that if the cable is lying flat, one end will have face-up contacts, and the other end will have face-down contacts).

; Exposure length: The length of the electrical contact that has been exposed at the termination of the cable.

; Stiffener: Most FFCs have some sort of extra material attached on the opposite side of the exposed length of the cable to facilitate [[Zero Insertion Force|ZIF]] or [[Low insertion force|LIF]] connections.

; Conductors size: The width and thickness of the conductors

Now FFC Cables are widely used in printer connections between the head and the motherboard, plotters, scanners, copiers, stereos, LCD appliances, fax machines, DVD players, and signal transmission and plate board connections. In modern electrical equipment, FFC Cables can be found almost everywhere.
