What is Solder Flux?

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 Read more…

What are Stacked Microvias?

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 Read more…

What are Tin Whiskers?

What Causes Tin Whiskers? Several factors contribute to the growth of tin whiskers: Stress in the Tin Plating Tin plating on electronic components can experience stress due to various reasons, such as: Temperature fluctuations Mechanical stress during manufacturing or handling Residual stress from the plating process When the stress in Read more…

What is a 4-Layer PCB Stackup?

Introduction to PCB Stackup A printed circuit board (PCB) stackup refers to the arrangement of copper and insulating layers that make up a PCB. The stackup defines the number of layers, their order, and the materials used in the fabrication process. A well-designed PCB stackup ensures proper functionality, signal integrity, Read more…

What is a Aspect Ratio?

Definition and Basic Concept Aspect Ratio is expressed as a ratio of two numbers, typically in the format of width:height. For example, a common aspect ratio in photography and digital displays is 16:9, which means that for every 16 units of width, there are 9 units of height. This ratio Read more…
