What are PCB Stencils? PCB stencils, also known as solder paste stencils, are thin metal sheets with laser-cut openings that correspond to the pads on a printed circuit board (PCB). These stencils are used to apply solder paste onto the pads of a PCB before components are placed and soldered. The use of PCB stencils ensures precise and consistent solder paste application, which is crucial for achieving reliable and high-quality solder joints. Types of PCB Read more…

Introduction to Silk Screen Printing for PCBs Silk screen printing, also known as screen printing or serigraphy, is a versatile printing technique that has been widely used in various industries for decades. In the realm of printed circuit board (PCB) manufacturing, silk screen printing plays a crucial role in applying non-conductive ink onto the surface of the PCB. This process is commonly referred to as “silk screening” or “legend printing” in the PCB industry. The Read more…

What is an SMT Stencil? An SMT stencil is a template used to apply solder paste onto the pads of a PCB during the SMT assembly process. The stencil has openings that match the size and location of the pads on the PCB, allowing for precise solder paste deposition. The thickness of the stencil determines the amount of solder paste applied, which is critical for forming reliable solder joints. Request PCB Manufacturing & Assembly Quote Read more…

Introduction to Flexible PCB Flexible printed circuit boards (PCBs) have revolutionized the electronics industry by providing a versatile and compact solution for interconnecting electronic components in a wide range of applications. Unlike traditional rigid PCBs, flexible PCBs are made from thin, pliable materials that allow them to bend, fold, and conform to various shapes and sizes. This unique characteristic has made flexible PCBs indispensable in the design and manufacturing of compact, lightweight, and portable electronic Read more…

Understanding the Basics of Power PCB Design Before diving into the specifics, it’s important to grasp the fundamental concepts of power PCB design. A power PCB is a printed circuit board that is specifically designed to handle high currents and voltages, making it an integral component in power electronics systems. Key Characteristics of Power PCBs Characteristic Description High Current Handling Power PCBs are designed to handle high currents, typically in the range of several amperes Read more…

Introduction to PCB Surface Finishes Printed Circuit Boards (PCBs) are essential components in modern electronics, providing a platform for mounting and interconnecting electronic components. The surface finish of a PCB plays a crucial role in its performance, reliability, and manufacturability. Two popular surface finish options are Hot Air Solder Leveling (HASL) and Electroless Nickel Immersion Gold (ENIG). In this article, we will explore the ten key differences between HASL and ENIG plating methods. What is Read more…

What is a Drone Board? A drone board, also known as a flight controller, is the central processing unit of a drone. It is responsible for controlling the drone’s movements, managing its sensors, and communicating with the remote control. The drone board receives input from various sensors, such as accelerometers, gyroscopes, and GPS modules, and uses this information to control the drone’s motors and maintain stable flight. Types of Drone Boards There are several types Read more…

What is a Gerber Viewer? A Gerber viewer is a software tool used to view and inspect Gerber files, which contain the design data needed to manufacture printed circuit boards (PCBs). Gerber files use the RS-274X format to describe the copper layers, solder mask, legend, and drill holes required to fabricate a PCB. A good Gerber viewer allows you to open these files, view the PCB design from different angles, inspect individual layers, and check Read more…

What is Soldermask Made Of? Soldermask is typically made of a photosensitive polymer that is applied to the PCB surface in liquid form. The most common types of soldermask are: Liquid Photoimageable Soldermask (LPISM): This is the most widely used type of soldermask. It is applied as a liquid and then exposed to UV light through a photomask, which hardens the exposed areas. Dry Film Soldermask (DFSM): This type of soldermask comes in the form Read more…
