MEDICAL ELECTRONICS
also avoid many of the issues associated with water-based processes, including moisture absorption and extended drying requirements. This supports a more stable and repeatable cleaning process, particularly for complex medical assemblies where consistency is critical.
Design still matters
by design decisions made much earlier in the process. Component spacing, standoff height and material selection all affect how easily residues can be removed. If cleaning is only considered at the end of the process, options are limited. Involving manufacturing and cleaning specialists at the design stage allows potential problem This may include reviewing component layouts, selecting compatible materials and issues later.
Validation is equally important. Cleaning that residues are removed and that materials are not affected. Ongoing monitoring is required to ensure the process remains
stable over time.
Process-driven approach Cleaning medical PCBAs is becoming more challenging as designs evolve. Higher densities, tighter geometries and more complex materials are exposing the
limitations of traditional approaches. A more controlled, process-driven approach is required. By considering cleaning earlier, selecting appropriate methods and validating performance, manufacturers can reduce risk and maintain the levels of reliability expected in medical devices.
