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.

Identical model motors vary, so each needs to be calibrated by banging against some edge ... think of the banging noise when an inkjet printer is turned on. Servo motors are good for robot wheels that have to turn a certain distance then stop. They are good for robots that have to balance themselves somehow. Auto pilots can use these to navigate a hallway. They are not good for spinning propellers like brushed dc motors and brushless motors.

The circular arrangement of electromagnets is divided into groups, each group called a phase, and there is an equal number of electromagnets per group. The number of groups is chosen by the designer of the stepper motor. The electromagnets of each group are interleaved with the electromagnets of other groups to form a uniform pattern of arrangement. For example, if the stepper motor has two groups identified as A or B, and ten electromagnets in total, then the grouping pattern would be ABABABABAB.

The five wires coming off the circuit board are the same as those coming off the ESC attached to the brushed dc motor and the servo motor circuit board "2 for power in and 3 go to the arduino". The pulses mean the same as the brushless dc motor. The only difference is that at maximum RPM, there are still pulses. There is not one long pulse like the brushed dc motor. The only physical difference is that there are three wires into the motor you may not be able to see them when it is mounted on a circuit board.

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.

This IC is available only in an 8-pin dual-flat no-leads (DFN) package, measuring a scant 2.5mm × 2.5mm with a tiny thickness of only 0.9mm. There is also, in addition to the eight pins, a thermal pad that is connected to ground (see image below).

Each of the two methods provides a carrier with standard dimensions and provisions for fitting, securing and supporting the irregular boards.
