[Case Study] Ensuring Reliability of "Lead-Free Solder Leveler" in Compliance with RoHS Directive
Analysis conducted using a fluorescent X-ray analyzer! Introducing a case study from a domestic printed circuit board manufacturer.
Under the European RoHS directive, the lead content in solder must be kept below 1000 ppm. However, during an analysis of the final products at the customer site, instances were confirmed where the lead content exceeded the standard value. As a result, it became necessary to check and guarantee the lead content in solder during the manufacturing of printed circuit boards. As a solution, a fluorescent X-ray analyzer was used to check the lead content in the solder bath. Additionally, by using a fluorescent X-ray thickness gauge for simple inspections, we confirmed the mix-up between lead-free solder products and eutectic solder products. By submitting and storing that data and analysis samples, it became possible to establish a system that ensures traceability and guarantees compliance.
