Jumper Settings in Mobile Phones
Jumpering word means give connection from one point to other bypassing in-between components. A good conductor wire is used to make a jumper which bypasses the components and pass on a signal or supply line for further uses.
When wire is used as a jumper, it must have sum special specifications as required. These jumper wires can be mainly of two types i.e insulated and non insulated. In the mobile phone insulated wires are used for jumpers. The thickness of these jumper wires is measured into “gaze.” The length of a jumper depends on the two points connected in between.
