What is Innerlayer Imaging in PCB Manufacturing? Innerlayer imaging, also known as primary imaging, is a critical step in the manufacturing process for multilayer printed circuit boards (PCBs). It involves transferring the circuit patterns onto the inner copper layers of the board before laminating them together into the final multilayer stack. Accurate and high-quality innerlayer […]
What is a White PCB? A white PCB, also known as a solder mask white PCB or a white solder mask PCB, is a type of printed circuit board (PCB) that features a white solder mask coating instead of the more common green color. The solder mask is a protective layer applied to the copper […]
What is BGA Soldering? BGA soldering is a method of attaching electronic components, such as microprocessors and memory chips, to a PCB using an array of small solder balls. These solder balls are arranged in a grid pattern on the bottom of the component package, allowing for a high number of connections in a small […]
Introduction to High-Voltage PCB Design High-voltage printed circuit boards (PCBs) are essential components in various applications, including power supplies, industrial control systems, and medical equipment. Designing high-voltage PCBs requires careful consideration of several factors to ensure reliable performance, safety, and longevity. In this article, we will explore the key aspects of high-voltage PCB design and […]
Understanding the Basics of Solder Flux What is Solder Flux? Solder flux is a chemical compound that is applied to the surfaces being soldered to improve the wetting and bonding characteristics of the solder. It helps to remove oxides, contaminants, and impurities from the metal surfaces, allowing the molten solder to flow smoothly and adhere […]
What are Microvias? Microvias are small holes drilled in a PCB to make electrical connections between layers. They are typically defined as blind vias (connecting an outer layer to an inner layer) or buried vias (connecting inner layers) with a diameter of 150 μm or less. Some key characteristics of microvias include: Small diameter (typically […]
