Introduction to High TG PCB High TG PCB, also known as high glass transition temperature printed circuit board, is a type of PCB that offers superior thermal and mechanical properties compared to standard PCBs. The term “TG” refers to the glass transition temperature, which is the temperature at which the […]

Understanding the Differences Between Immersion Gold and Gold Plating When it comes to applying a thin layer of gold onto a substrate material like copper or nickel for protective and aesthetic purposes, two common methods are immersion gold and gold electroplating. While both result in a gold surface finish, there […]

Introduction to Solder Mask and Its Function Solder mask, also known as solder resist or solder stop mask, is a thin lacquer-like layer of polymer applied to the copper traces of a printed circuit board (PCB). Its primary function is to prevent solder from bridging between conductors and creating short […]

What is Through-Hole Technology? Through-hole technology, also known as through-hole mounting (THM) or plated-through-hole (PTH), is a method of mounting electronic components on printed circuit boards (PCBs). In this process, component leads are inserted through drilled holes in the PCB and soldered to pads on the opposite side, creating a […]

What is a PCB? A printed circuit board, or PCB, is the foundation of nearly all modern electronic devices. PCBs are flat boards made of insulating materials like fiberglass, with conductive copper traces printed on them to connect various electronic components. The components – such as resistors, capacitors, and integrated […]

Introduction to PCB Components Printed circuit boards (PCBs) form the backbone of virtually all modern electronic devices. They provide a platform to mechanically support and electrically connect various electronic components using conductive tracks, pads and other features. The components mounted on PCBs are what give the circuit board its functionality. […]

Introduction to PCB Components A mobile cell phone is a complex electronic device that consists of various components mounted on a Printed Circuit Board (PCB). The PCB serves as the backbone of the phone, connecting all the components and allowing them to function together. Understanding the different parts and components […]

Introduction to Goldfinger PCBs Goldfinger PCBs, also known as gold plated printed circuit boards, are a type of high-quality PCB that uses a layer of gold plating over the copper traces and pads. The gold plating provides several benefits, including improved corrosion resistance, better electrical conductivity, and enhanced solderability. These […]

Introduction to Heavy Copper PCB Heavy Copper PCBs, also known as thick copper PCBs or high current PCBs, are printed circuit boards that feature thicker copper traces than standard PCBs. These specialized boards are designed to handle higher currents and provide better thermal management, making them ideal for applications that […]

1. Cold Solder Joints Cold solder joints occur when the solder does not melt completely, resulting in a dull, lumpy appearance. This can happen due to insufficient heat, improper fluxing, or moving the joint before the solder has solidified. To avoid cold solder joints: – Ensure your soldering iron is […]
