What are PCB Castellations? PCB castellations are plated half-circle cutouts or slots along the edge of a printed circuit board (PCB). The term “castellation” comes from their resemblance to the turrets and battlements on the top of a castle wall. Castellations serve as a connection point for plugging the PCB […]
What Are Rubber Duck Antennas? A rubber duck antenna, also known as a rubber ducky antenna, is a type of omnidirectional antenna commonly used in portable radio equipment, such as handheld transceivers, cordless phones, and Wi-Fi devices. The name “rubber duck” comes from the antenna’s flexible, duck-like appearance. These antennas […]
What is a Log Amplifier? A log amplifier, short for logarithmic amplifier, is an electronic amplifier that produces an output signal that is proportional to the logarithm of the input signal. In other words, the voltage gain of a log amp decreases as the input signal increases. This non-linear behavior […]

What is a BC558 Transistor? The BC558 is a PNP transistor, meaning that it has a positive-negative-positive semiconductor layer structure. It is a general-purpose transistor suitable for low-power amplification and switching applications. The BC558 is part of the BC5xx series of transistors, which are known for their reliability and performance. […]
What is Photolithography? Photolithography, also known as optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical “photoresist” on the substrate. […]
The Importance of Wiring Harness Labels Identification and Traceability Labeling wires in a wiring harness is essential for identification and traceability purposes. In complex systems with numerous wires, labels help technicians quickly identify specific wires and their corresponding functions. This is particularly important during troubleshooting, maintenance, and repair processes, as […]
