Splices may be used within 30cm of a termination device when attaching to the pigtail spare lead of a potted termination device, to splice multiple wires to a single wire, or to adjust the wire sizes so that they are compatible with the contact crimp barrel sizes.

In a demanding application, we may not have the time to continuously check the pointers to see if they have reached the end of the buffer and wrap them back to the beginning of the buffer when necessary. As a result, a DSP processor uses dedicated hardware to provide some fast circular buffers.This hardware implementation automatically checks the status of the pointers and updates them accordingly.

The tab-route or breakaway tab method is suitable for PCBs with either similar or different designs, or where it is not possible or practical to use the V-grooves. The designer leaves a perforated tabs routing space between the different or similar boards, hence allowing for separation after processing.

The circuit board for this CD motor has no electronics on it. A ribbon cable attaches 11 wires to another controller circuit board. But often the controller is built onto the same circuit board. The circuit boards interface with a controller in two ways.

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).

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.

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.

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.

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

Generally, the fixture materials, which range from synthetic plastics and stones to aluminum alloys and epoxy glass, should be electrostatic neutral, and able to withstand repeated thermal cycles and chemicals without deforming or wear. In particular, the thin fixtures provide better thermal management.
