Flow soldering 与 reflow的区别

Webnickel, and other solderable materials. During laser reflow of solder paste, the entire reflow heating cycle can be completed in under a second with full wetting and a textbook-perfect fillet. Excessively thick intermetallic layers can contribute to brittle fracture of solder joints. Scavenging is most often of concern with plated parts and WebReflow soldering is the most widely used method of attaching surface mount components to printed circuit boards (PCBs). The aim of the process is to form acceptable solder joints by first pre-heating the components/PCB/solder paste and then melting the solder without causing damage by overheating. The key aspects that lead to an effective ...

WebTwo options are available for reflow soldering of lead-free sphere BGA packaged components to printed circuit board (PCB) assemblies: • Tin-based, lead free solder paste (recommended method). • Traditional lead-bearing solder pastes (such as 63Sn37Pb). The board reflow procedure may use an infrared (IR) or a convection heating process. WebReflow soldering permanently glues components that are first temporarily stuck to their pads on circuit boards using solder paste that will be melted through hot air or other thermal radiation conduction.
