The second (which is always the same in car wiring) is the diameter of each strand in millimetres. Twisting wires together and fitting spade terminals twist bare ends together and solder them.Cover the joint with insulating tape. Tag connectors are closedround the bare wire withpliers, then soldered. A spade terminal is easy to disconnect andreconnect. Methods of joining, wires To connect two wires, use a wire stripper to remove about in. (19 mm) of insulation from each wire.

There are different panelization and de-panelization methods depending on the application of the PCB, thickness, shape, component layout, type of edges, and other factors. The two popular methods are the V-groove panelization and the breakaway tab panelization. Each of these uses a different method to separate the boards from the main array and has its advantages and limitations.

Today servomechanisms are used in automatic machine tools, satellite-tracking antennas, remote control airplanes, automatic navigation systems on boats and planes, and antiaircraft-gun control systems. Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometre positioning accuracy. In industrial machines, servos are used to perform complex motion, in many applications.

Most computer controlled DC motors are pulsed. Pulses of a fixed voltage are sent to the motor, usually by an Electronic Speed Controller or ESC. A pulse of 1.5 ms causes no motion. Wider pulses cause faster spinning in one direction. Shorter pulses cause faster spinning in the opposite direction. Eventually, an overstressed ESC stops pulsing and turns one wire on and one wire off, depending on the direction.

SMT fixtures are rigid PCB carriers that allow manufacturers to load single or multiple irregular boards, and then take them through the standard processing machines. This makes it possible to carry out tasks such as automatic mounting of electronic components, infra-red reflow soldering, wave soldering, automatic testing, etc.

A lousy wiring job will keep your electrical accessories from operating at full potential—and that means subpar performance. Many people are intimidated by the prospect of wiring a vehicle. But a proper wiring job doesn’t have to be a scary task—we’ve put together a few tips to help make the job a little bit smoother.

Grip the cable, connector uppermost, in a vice or self-locking pliers, so that the connector rests on top of the vice and cannot slide down the wire when soldering. Inside a bullet connector. Apply solder on the top of the connector, and let it melt and run down inside. Trim off the protruding strands with wire cutters.
