What is FR4? FR4 is a composite material made from woven fiberglass cloth impregnated with an epoxy resin binder. The “FR” stands for “Flame Retardant,” indicating that the material has been treated to resist catching fire and spreading flames. The “4” in FR4 refers to the specific grade of the […]

Introduction to Peelable Soldermask A peelable soldermask, also known as a temporary soldermask or removable soldermask, is a protective coating applied to printed circuit boards (PCBs) during the manufacturing process. This special type of soldermask is designed to be easily removed from specific areas of the PCB when needed, allowing […]

What is temperature correction? Temperature correction is a method used to compensate for the influence of temperature variations on the measurement of a parameter. It involves adjusting the measured value of a parameter to account for the deviation caused by temperature changes. By applying temperature correction, the true value of […]

Introduction to PCB Data Upload Uploading PCB (printed circuit board) data is an essential step in the PCB design and manufacturing process. PCB data contains all the necessary information required to fabricate the physical circuit board, including the copper layers, drill holes, component footprints, and more. Properly preparing and uploading […]

Introduction to Copper fills Copper fills, also known as copper vias or PTHs (plated through holes), are a crucial component in printed circuit boards (PCBs). They provide electrical connections between different layers of a multi-layer PCB, enabling the flow of signals and power throughout the board. From a mechanical perspective, […]

What are Build-ups? Build-ups, in the context of construction and engineering, refer to the process of gradually increasing the complexity or size of a structure or system. This approach is commonly used in various fields, such as software development, manufacturing, and project management. The main purpose of build-ups is to […]

What are Cross Sections? A cross section is a view of an object as if it had been sliced through to reveal its internal structure. Imagine cutting a loaf of bread in half and looking at the exposed surface – this is essentially a cross section. Cross sections can be […]

Introduction to cEDM cEDM, or Collaborative Electronic Design and Manufacturing, is a groundbreaking approach that combines the power of collaborative design with the efficiency of modern manufacturing techniques. This innovative methodology is transforming the way electronics are designed and produced, enabling companies to bring their products to market faster, more […]

What is ENEPIG? ENEPIG is a surface finish that consists of three layers: electroless nickel, electroless palladium, and immersion gold. The process involves depositing a layer of electroless nickel onto the copper pads of the PCB, followed by a thin layer of electroless palladium, and finally, a layer of immersion […]

Understanding Lead Free Soldering Lead-free soldering is the process of joining two or more metal surfaces using a lead-free solder alloy. The most common lead-free solder alloys are tin-silver-copper (SAC) alloys, with the most popular being SAC305 (96.5% tin, 3% silver, and 0.5% copper). Advantages of Lead Free Soldering Environmentally […]
