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.

As you may have noticed, this is one of those annoying situations in which the pin configuration is the opposite of what you want: the DAC’s input pins move from bit 7 to bit 0 going downward, whereas the MCU’s output pins move from bit 7 to bit 0 going upward. I couldn’t remedy this by re-assigning the microcontroller pins because I wanted the data bits to correspond to the actual bits of the Port 2 register (so that I could write a full byte to the DAC without moving bits around). So I ended up with some awkward routing, but nothing terrible.

It’s always a good idea to minimize the length of traces carrying high-frequency digital signals. First of all, there are noise benefits: a shorter, more direct trace reduces the amount of noise that would otherwise be coupled into adjacent traces, and a shorter trace also reduces electromagnetic interference (EMI) because it is less effective as an antenna. The second issue is related to transmission-line effects. Minimizing trace length is a simple way to avoid problems related to signal reflections. However, reflection is not a significant concern at frequencies in the 10 MHz range, unless you are dealing with long interconnections or a very large PCB.

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.

The sharp edge of the hole will soon chafe through wire insulation and cause a short circuit. Whenever you pull a connection apart, look for corrosion which might cause bad contact. If necessary, clean contacting metal surfaces with a fine file or emery cloth.

The AWG doesn’t have high current requirements, but the board house doesn’t give you a discount for using less copper, so you might as well opt for large (= low-resistance, low-inductance) traces if you have the room.

Its wire coil is actuated by a smaller current from the ignition switch, at which time the iron core slams down to make contact and turn on the starter motor. Most non-Ford starter motors employ a solenoid built into the motor itself. This type of solenoid not only provides the motors electrical power but also mechanically engages the starters drive gear onto the flywheel.

In fact, it is recommended, because the IC pad pitch is just 0.5 mm, that only one solder mask opening should be used for all four pads on one side. It is also suggested, when using solder paste printing, that a laser-cut stainless steel stencil with trapezoidal walls and with a stencil thickness of 0.1 or 0.125 mm should be used. See the images below. This information should be quite helpful for a PCB layout design team.
