Introduction to Vias and Tented Vias Vias are an essential component in printed circuit board (PCB) design, allowing electrical connections between different layers of a multi-layer PCB. A via consists of a drilled hole that is electroplated with a conductive material, typically copper, to create an electrical pathway. Tented vias are a specific type of […]
What is Tenting Via? Tenting via is a technique used in PCB fabrication where the via holes on the circuit board are covered or “tented” with a thin layer of solder mask material. This process involves applying solder mask over the via holes, creating a smooth and uniform surface on both sides of the PCB. […]
Introduction to PCB trace width Printed Circuit Board (PCB) design is a complex process that involves various factors, including component placement, routing, and trace width. Among these factors, trace width plays a crucial role in ensuring the proper functioning and reliability of the PCB. In this article, we will explore the importance of PCB trace […]
Understanding Thermal Pads What are Thermal Pads? Thermal pads are thin, flexible materials that are placed between electronic components and heat sinks to enhance heat dissipation. They are typically made from materials with high thermal conductivity, such as silicone, polyurethane, or various filled elastomers. These pads are designed to conform to the surface of the […]
What is Heavy Copper PCB? Heavy Copper PCBs are printed circuit boards that use thicker copper traces than standard PCBs. While a typical PCB uses 1-2 oz. copper (35-70 μm thick), heavy copper PCBs use copper traces ranging from 3 oz. to 20 oz. (105-700 μm thick). The thicker copper allows for higher current carrying […]
Understanding PCB Fabrication Before diving into the factors to consider when choosing a PCB fabrication service, let’s briefly understand what PCB fabrication entails. What is PCB Fabrication? PCB fabrication is the process of manufacturing printed circuit boards. It involves several steps, including: Designing the PCB layout Printing the circuit pattern on the copper-clad board Etching […]

PCB manufacturing in China has experienced remarkable growth over the past few decades, thanks to the country’s vast resources, skilled workforce, and favorable […]
Introduction to MIL-PRF-31032 Certification MIL-PRF-31032 is a crucial certification for PCB Manufacturers that ensures the production of high-quality, reliable printed circuit boards for use in military and aerospace applications. This certification, issued by the United States Department of Defense (DoD), sets stringent requirements for the design, fabrication, and testing of PCBs to guarantee their performance […]
The Risks Associated with Traditional PCB Fabrication & Assembly Health Risks for Workers Conventional PCB manufacturing processes involve the use of various chemicals, including: Copper etchants (e.g., ferric chloride, ammonium persulfate) Photoresists and developers Solvents (e.g., isopropyl alcohol, acetone) Tin-lead solder Exposure to these chemicals can lead to a range of health issues for workers, […]
Introduction to Flexible PCBs Flexible printed circuit boards (PCBs) have revolutionized the electronics industry with their versatility, durability, and lightweight design. Unlike traditional rigid PCBs, flexible PCBs can bend, twist, and conform to various shapes, making them ideal for applications where space is limited or where the device needs to move or flex. One such […]
