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.

STARTER MOTOR — This is a powerful electric motor that engages the cars flywheel in order to spin the crankshaft. As in all electric motors, the starter is composed of windings of wire that form loops, ending at the commutator segments "remember these from the generator". The armature coils are mounted on the motors central shaftsupported with bearings and the field coils are formed into four or more "shoes", placed inside the steel frame of the starter.

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.

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).

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.

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.

A switch turns them on. Higher voltages cause them to spin faster. Often geared down in toys, they are designed to spin fast. If turned on and forced to not spin, the motor will heat up, and may even burn up. The motor is made by copper wire covered with clear paint, and wound together in a ball. When the motor heats up too much, the paint turns into smoke, nearby copper wires connect, the motor becomes weaker, the motor heats up more, more smoke comes out, etc. The winding resistance keeps going down. Measure the winding resistance when the motor is new and measure again when there are problems.

Care should be taken when depaneling the perforated-tab PCB array; otherwise, an incorrect method will splinter or tear the solder-mask or active surface layer. The ideal breakout method should not cause any damage to the board or transfer stress from the PCB surface to the components.
