Abstract:
A power tool that includes a motor and a printed circuit board (“PCB”). The motor includes a rotor and a stator. The stator includes a plurality of stator terminals. The PCB is electrically connected to the stator. The PCB includes a switch and an embedded busbar. A first end of the embedded busbar is electrically connected to the switch. The embedded busbar extends away from the PCB. A second end of the embedded busbar electrically connects to a stator terminal of the plurality of stator terminals for providing power to the motor using the switch. The embedded bus bar is embedded between two layers of the printed circuit board.

The present disclosure is directed at an AC drive for driving an electric motor. The AC drive has a 3-phase diode bridge, an inverter and a snubber board with multilayer printed circuit board elements, wherein the power lane in every layer of every element is connected to only one potential DC- or DC+, each element includes two capacitors of inverted polarity, wherein each element includes two C-shaped bus bars and wherein the C-shaped bus bars of two neighbouring elements are placed in close proximity to each other.
Abstract:
Flexible printed circuit boards and related methods are disclosed herein. An example printed circuit board includes a controller interface coupled to a surface of the printed circuit board between a first end of the printed circuit board and a second end of the printed circuit board. The example printed circuit board includes a connector coupled to the surface proximate to the first end. The example printed circuit board includes a notch formed between the controller interface and the connector. The notch is to form a narrowed portion of the printed circuit board to enable the printed circuit board to bend at the narrowed portion.
Abstract:
An electronic component has a support member, an SAW element which is mounted on the support member with a space S therebetween and which has a facing surface which faces the support member, and a resin portion which covers the SAW element and which is provided so as to seal the space S.
