  • Dispelling 10 Myths About Nitrogen Reflow (.pdf)
    In my twenty years in the electronics manufacturing industry, I have heard a lot of claims made about the use of nitrogen in inerted soldering processes: many of them completely wrong. In this paper, we will talk about reflow in an enclosed oven, although many of these discussions may pertain
  • Recommended SMD Reflow for PCA Electronics Products
    PCA components have been designed and tested to withstand all typical Surface Mount Device (SMD) reflow processes using Infra Red (IR), Convection or a combination IR/Convection inline ovens. However, due to the various materials used in magnetic components, extreme care must be taken

    One of the key factors of reflow oven is preheating. The preheating of a component and PCB is basically the same in leaded and leadfree soldering. Preheating is the range from room temperature to the melting point of solder. ept_H1H4.eps Surface Mount Technology (SMT). Failure Analysis
  • Intro to Aqueous Cleaning Equipment (.pdf)
    In-line equipment is designed to continuously clean large numbers of circuit boards in a short period of time. As the name implies, the washer receives boards by conveyor, from preceding process units (e.g. reflow oven) cleans and dries them in one operation. Spray-in-air indicates
