What is PCB Copper Thickness? PCB copper thickness, also known as copper weight or copper foil thickness, is the thickness of the copper layer that is laminated onto the insulating substrate material of a PCB. The copper thickness is typically measured in ounces per square foot (oz/ft²) or microns (µm). […]

Understanding Thermal dissipation Thermal dissipation refers to the process of removing heat from a system and transferring it to the surrounding environment. This is essential to maintain the temperature of the system within its operating limits and prevent overheating, which can lead to reduced performance, component damage, and even complete […]

Understanding PCB sensor placement PCB sensor placement refers to the process of determining the optimal location for external sensors on a PCB. External sensors are components that detect and measure various physical quantities such as temperature, pressure, light, or motion. These sensors are essential for many electronic devices, including smart […]

What is TQFP? TQFP, or Thin Quad Flat Pack, is a surface-mount package that has leads on all four sides of the package. It is a thinner version of the QFP (Quad Flat Pack) package, with a typical thickness of 1.0 mm or less. TQFP packages are commonly used for […]

Introduction to IC Packaging Integrated Circuit (IC) packaging is the final stage of semiconductor device fabrication, where the tiny block of semiconducting material is encased in a supporting case that prevents physical damage and corrosion. The package also supports the electrical contacts which connect the device to a circuit board. […]

Types of PCB Equipment 1. PCB Design Software PCB design software is used to create the layout and schematic of a PCB. It allows designers to create complex designs with ease and accuracy. Some popular PCB design software includes: Altium Designer Eagle KiCad OrCAD These software tools offer features such […]

What is a PCB Antipad? A PCB (printed circuit board) antipad, also known as a thermal relief or thermal pad, is a design feature used to improve solderability and reduce thermal stress on plated through holes (PTHs). An antipad is essentially a clearance area around a PTH where the copper […]
