How to avoid complications with flex cable?

What is flex cable?

Flex cable, also referred to as FFC (Flat flexible cable) is an extremely important and inseparable part of every smartphone or tablet, for example. Although the possibilities of its use are much wider, in mobiles the flex cable is used primarily to connect the motherboard to the LCD display.

Why is flex cable prone to be damaged?

Flex cable, as its name suggests, is a very flexible flat component, made to connect two parts of the device, in a very limited space. Probably the best example is modern smartphones. In an effort to create the thinnest possible devices, manufacturers have been forced to come up with a solution that can reliably transfer data from the display to the motherboard (and vice versa) without requiring too much space. Thanks to its construction and flexibility, the flex cable can really do it, but the tax on its capabilities is its increased susceptibility to various types of damage.

How to find out if flex cable is damaged?

The best indication that the flex cable has been damaged is a malfunction of the display or its accidental outages. Such a device is, of course, unusable. It is therefore very important to take the utmost care in any operation that involves opening the device.
