Soldering capabilities is a critical concern for quality repairs lasting years in the field after the repair is completed. All technicians and engineers qualified to solder on medical devices must have the proper soldering certifications. Without having these certifications, there is no way to guarantee the soldering work completed is up to standard. If the correct part is used and the coil has poor soldering, the MRI coil may still show poor images or last only a few weeks before service is required again.
