STARTER SOLENOID "Relay" — All cars are wired so that the batterys main cable connects to the starter motor windings "the thick cable is needed for large current flow, right?". This wire must be switched on and off, of course, and it would be costly and inefficient to route it through the ignition switch "not to mention the size of the switchs components required to carry such current!". Consequently, a relay is necessary.

The decoupling capacitors (C4, C5, C6, C7, C9, C10, C11) are arranged around the perimeter of the chip, very close to their respective power pins and to the vias that connect the caps to the internal planes. Notice how the smaller cap is always closer to the power pin; this is because we rely more on the lower-value capacitor for high-frequency bypassing, and thus the first priority is minimizing the inductance and resistance between the smaller cap and the pin.

Use a wire stripper to remove about 1/8in. (3 mm) of insulation from the end of the wire. Lay the bare strands in the inner section of the connector. Use crimping pliers to tighten the two small tongues firmly around the insulated part of the wire. On the other side of the connector, push the wire strands back and down flat. Hold the connector blade upwards to avoid solder running into the spade part.

Panelization is the arranging of arrays of multiple PCBs onto a single substrate that fits in the standard processing machine. A panel may hold multiple boards with similar or different sizes and shapes. This method is faster and less costly compared to the fixtures, which require a custom carrier for every new PCB design.

Look at these wikicommons pictures. Taking apart a CD player and finding the motor is fairly easy.Start by turning it upside down and removing the screws holding the bottom plate on.

The remaining part joins the separate boards and is then cut with a machine during the depaneling. This helps to reduce the stress on the PCB. One challenge with the V-groove method is that it is restrictive and cannot be used with PCBs that have overhanging components over the edges.

There may be some resistance that feels like removing magnets from each other. Underneath the cup of all outrunner brushless motors is a series of coils. On some motors, between the coils, are hall effect probes. Hall effect probes detect the spinning magnetic field and provide a pulse out of the brushless motors to the electronics. From this pulse the electronics can precisely control the speed of the motor
