Q: Water Washing PCBs: Is it Necessary
A: Water washing PCBs is crucial in the printed circuit board manufacturing process and during PCB assembly. This process helps remove contaminants, residues, and fluxes left behind after soldering and assembly. Water washing is essential for ensuring the PCB’s reliability and performance. Here’s a step-by-step…
Difference Between Solder Flux and Solder Paste
Solder flux and solder paste are two different materials used in soldering processes, each serving a specific purpose in electronics assembly. Here are the critical differences between them: In summary, soldering flux is primarily used to clean and prepare soldering surfaces. In contrast, holding paste…
What about PCB Solder Flux Residue
PCB solder flux residue refers to the leftover material that remains on the surface after soldering. Solder flux is a chemical substance used in soldering processes to improve the quality and reliability of solder joints. Let’s start with the purposes of solder flux: There are…
Q: What is Mid-Chip Solder Balling
A: Mid-chip solder balling is a phenomenon that can occur during the soldering process in electronic assembly, particularly in surface mount technology (SMT) soldering. It refers to forming small, spherical solder balls or droplets that appear near the center of a solder joint on a…
Clean versus No-Clean Solder Paste
Clean versus No-Clean Solder Paste…both are used in the electronics manufacturing process, specifically for soldering components onto printed circuit boards (PCBs). Let’s delve into what each type entails and why they might be chosen: Due to these potential issues, clean solder paste requires thorough cleaning…
Q: What’s PCB Cleaning After SMT Assembly
A: After Surface Mount Technology (SMT) assembly, the printed circuit boards (PCBs) often need to undergo a cleaning process to remove any flux residues, soldering paste, and other contaminants that might be present on the board’s surface. Cleaning the PCBs is crucial to ensure their…
Q: What is a PCB Solder Mask
A: A PCB solder mask, also known as solder resist or solder stop mask, is a protective layer applied to the surface of a PCB to insulate and prevent solder from unintentionally bridging or short-circuiting the electrical connections on the board during the soldering process….
Q: What Determines Solder Joint Strength
A: The solder joint strength is not determined by whether they are “leaded” or “non-leaded” but by factors such as the solder composition, joint design, and application method. Leaded solder typically contains a small amount of lead, which helps to lower the melting temperature and…
Q: What is No-Clean Solder Paste
A: No-clean solder paste is a type of solder paste that contains a flux formulation designed to leave minimal residue after the soldering process. Solder paste is a mixture of tiny solder particles and flux used in surface mount technology (SMT) to attach components to…
