When working with a printed circuit board (PCB), it is vital to incorporate one or more resistors as a means of controlling current flow and for the benefit of other applications. These include dividing voltage, generating heat, matching and loading circuits, controlling gain, powering LED lights, and fixing time constraints. For any electronics project you might partake in, it is important to understand what exactly a resistor is, how it functions, and how to choose the right design. As such, this blog will provide a brief overview of all you need to know. Read more >>

A capacitor is a common part type that is charged with storing electrical energy in an electric field, serving as a passive electronic component that establishes capacitance in a circuit. There are many types of capacitors available, each varying in its design and capabilities. Film capacitors are a common option for many applications, and they are discernible by their thin plastic film that serves as the dielectric. In this blog, we will discuss the film capacitor in more detail, allowing you to have a better understanding of its function and applications. Read more >>

In addition to full-scale wings, aircraft have a smaller set of wings known as “winglets.” The winglets extend off the end of the aircraft’s wings at an upward or downward angle as a means of increasing efficiency. Winglets function to decrease drag and can decrease fuel consumption by up to 4%. The ability to identify and understand how airplane winglets work is crucial to forming a more precise working knowledge of aeronautics, so the following blog will provide an overview for your benefit.

When it comes to safety, there are a lot of requirements that aircraft must meet to create a reasonably prepared environment for emergencies. Fire extinguishers are a common safety protocol in most public places, and a passenger aircraft is no exception. In fact, a strict passenger to portable fire extinguisher ratio must be maintained within most aircraft. Extinguishers are stored in both the cabin and the flight deck, and a variety of materials are used depending on the severity of the fire. This blog will cover the different types of extinguishing agents as well as the ideal situation in which each should be used in flight. Read more >>

 In aerospace and military missions, many important functions rely on printed circuit boards (PCBs) to provide electricity. A malfunctioning PCB can jeopardize an entire flight, so it is important to make sure the PCB can withstand harsh situations. Environmental exposure can lead to issues such as corrosion, so PCBs are manufactured with a conformal coating to protect the exposed components on the surface of the board. A conformal coating is a thin, clear polymeric film that coats the board’s surface and ultimately ensures a longer working lifespan. Conformal coatings are used across many fields, but different environments demand different forms of protection. For this reason, it is important to make sure the correct material is chosen for the coating. Read more >>
