What are Solder Stencils? Solder stencils, also known as solder paste stencils, are thin metal sheets with cutouts that match the pads on a printed circuit board (PCB). They are used to apply solder paste onto the PCB pads in a precise and controlled manner before components are placed and […]

Main Components of a Custom Drone Board At the heart of any custom drone board are the following critical components: 1. Flight Controller Chip The flight controller is the main processor that runs the software and algorithms to keep the drone stable and flying as commanded. Some of the most […]

What are HASL and ENIG Plating Methods? HASL (Hot Air Solder Leveling) and ENIG (Electroless Nickel Immersion Gold) are two common surface finish plating methods used in PCB manufacturing to protect exposed copper pads and provide a solderable surface. The choice between HASL vs ENIG depends on various factors such […]

Understanding Polygon Pours in Altium Designer Polygon pours are a crucial feature in PCB design software like Altium Designer. They allow designers to fill large copper areas on the PCB with a solid connection to a specified net, providing low-impedance power distribution, shielding, and improved thermal management. However, when working […]

Understanding Power Requirements Determining Voltage and Current Needs The first step in power PCB Design is to understand the power requirements of your system. This involves determining the voltage and current needs of each component on the board. It is essential to consider the maximum power consumption of each component […]

Introduction to Flexible PCB Flexible printed circuit boards, or flexible PCBs, have revolutionized the electronics industry by providing a versatile and compact solution for interconnecting electronic components. Unlike traditional rigid PCBs, flexible PCBs are made from thin, flexible materials that can bend, twist, and fold without breaking or losing their […]

What Are PCB Vias? PCB vias are small holes drilled through a printed circuit board that allow electrical connections between different layers of the board. Vias are essential components in PCB Design as they enable compact and complex circuit routing in a limited space. By using vias, designers can create […]

Introduction to Solder Mask Solder mask, also known as solder resist or solder stop, is a thin protective layer applied to the copper traces of a printed circuit board (PCB). This coating serves multiple purposes, including preventing solder bridges from forming between closely spaced solder pads, protecting the copper from […]

What is HASL? HASL is a surface finish that involves dipping the PCB into a molten solder bath and then using hot air to level the surface. This process creates a thin layer of solder on the exposed copper pads, providing protection against oxidation and ensuring good solderability. Advantages of […]

What is a PCB File? A PCB file, short for Printed Circuit Board file, is a digital file format used to store the design data for a printed circuit board. PCB files contain all the information needed to manufacture a physical PCB, including the board layout, component placement, routing, drill […]
