PCB solder types used in electronics manufacturing and repair range. Various types of solder are used in PCB soldering, each with its own characteristics and applications. The most common PCB solder types include: The choice of solder depends on the specific requirements of the PCB…
Q: What are PCB Solder Bridges
A: PCB Solder bridges, also known as solder shorts or solder blobs, are unintended electrical connections created by excess solder material that connects two or more adjacent conductive elements on a printed circuit board (PCB) or electronic component. These connections can cause electrical problems and…
Q: What is Solder Paste Slump
A: Solder paste slump refers to the tendency of solder paste to change in consistency and flow characteristics over time, particularly during storage or during the soldering process. Solder paste is a critical material used in surface-mount technology (SMT) for attaching electronic components to printed…
Stop Solder Dewetting: Causes and Prevention
Solder dewetting is a common issue in soldering processes, particularly in electronics manufacturing, where solder joints lose their integrity and wetting ability, leading to a reduction in solder adhesion to the surfaces being soldered. This can result in poor electrical connections, reduced mechanical strength, and…
Electronic PCB Selective Soldering
Electronic PCB selective soldering is a specialized process used in electronics manufacturing to precisely solder specific components onto a printed circuit board (PCB). This process benefits through-hole components with leads that must be soldered to the PCB. Here’s how electronic PCB selective soldering works: Electronic…
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…
Q: Why Use PCB Solder Paste
A: PCB Solder paste is a material used in electronics manufacturing to facilitate soldering. It’s a mixture of tiny solder particles suspended in a flux medium. When applied to the pads of electronic components and printed circuit boards, solder paste holds the components in place…
