Types of Gold Embrittlement There are several types of gold embrittlement that can occur due to different mechanisms: Hydrogen Embrittlement Hydrogen embrittlement of gold can occur when atomic hydrogen diffuses into the gold lattice, causing a reduction in ductility and toughness. This type of embrittlement is often reversible if the hydrogen is removed through heating […]
How HASL Surface Finish is Applied The HASL process consists of several steps to ensure a high-quality surface finish: PCB Preparation: The PCB undergoes a cleaning process to remove any contaminants or oxides from the copper surface. This step is crucial for achieving a uniform and adherent solder coating. Fluxing: A thin layer of flux […]
Introduction to PCB Surface Finish When it comes to designing and manufacturing Printed Circuit Boards (PCBs), selecting the appropriate surface finish is a crucial decision. The surface finish not only protects the copper traces and pads from oxidation and corrosion but also ensures reliable solderability and enhances the overall performance of the PCB. With a […]
What is Immersion Silver? Immersion silver (IAg) is a lead-free, RoHS-compliant surface finish used on printed circuit boards (PCBs). It provides excellent solderability, conductivity, and shelf life for PCB Components. Immersion silver has gained popularity as an alternative to other finishes like hot air solder leveling (HASL), electroless nickel immersion gold (ENIG), and organic solderability […]
Introduction to High Tg PCBs High Tg PCBs, or Printed Circuit Boards with a high glass transition temperature (Tg), are a type of advanced PCB designed to withstand extreme temperatures and harsh environmental conditions. These PCBs are essential for applications in industries such as aerospace, automotive, military, and telecommunications, where reliability and durability are critical […]
What is the Purpose of HiPot Testing? The primary purpose of HiPot testing is to verify the integrity of electrical insulation in products and components. Insulation is a critical safety feature that prevents current from flowing between conductors or from conductors to ground, which could result in electric shock, fire, or other hazards. By applying […]
The Need for IPC-2581 Standard The electronics industry has long faced challenges in efficiently exchanging PCB design and manufacturing data due to the variety of proprietary formats used by different software tools and manufacturers. This lack of standardization often leads to errors, delays, and increased costs in the PCB manufacturing process. The IPC-2581 standard addresses […]
The History of Lead-based Soldering Lead has been used in soldering for centuries, with evidence of its use dating back to ancient civilizations. In the modern era, lead-based solders became the standard in the electronics industry due to their favorable properties, such as low melting point, good wettability, and excellent electrical conductivity. The most common […]
What Are the Benefits of High Tg PCB? There are several key benefits and advantages of using high TG PCBs: 1. Enhanced Thermal Stability The primary benefit of high TG PCB is their enhanced thermal stability. With a glass transition temperature typically above 170°C, these PCBs are able to withstand higher operating temperatures without deformation […]
Understanding the Need for Backdrilling PCB As technology advances and electronic devices become more sophisticated, the demand for high-speed PCBs has increased significantly.
