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 […]
Why is PCB trace width Clearance Important? Preventing Short Circuits One of the primary reasons for maintaining adequate PCB trace width clearance is to prevent short circuits. When traces are placed too close to each other or other conductive features, there is a risk of unintended electrical connections. These short circuits can cause the PCB […]
What is PCB Tenting? PCB tenting, also known as via tenting or Tented Vias, is a process in printed circuit board (PCB) manufacturing where the small holes (vias) that connect different layers of the board are covered with a thin layer of solder mask material. This technique is used to protect the vias from contamination, […]
Definition and Purpose of Thermal Vias What are Thermal Vias? Thermal vias are specialized vias (vertical interconnect access) that are strategically placed in a PCB to facilitate heat transfer from heat-generating components to the opposite side of the board or to a heatsink. Unlike regular vias, which primarily serve as electrical connections between layers, thermal […]
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 […]
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 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 […]
Introduction to PCB Manufacturing in China China has emerged as a global leader in the production of printed circuit boards (PCBs), with a thriving industry that offers high-quality products at competitive prices. PCB manufacturing in China has experienced remarkable growth over the past few decades, thanks to the country’s vast resources, skilled workforce, and favorable […]
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 […]
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 […]
