Note it is just as important to conform to the times specified l as the temperatures. Pre-heat should not exceed 217°C and rate of heating from 25°C to 217°C should be limited to 4deg C/sec Peak soldering temperature should not exceed 260°C. Time at peak temperature should not exceed 10 seconds. Total reflow time should not exceed 7 minutes. Should it be required to solder the can to the PCB, then the area and volume of solder should be kept to an absolute minimum, and trials should be conducted to determine if the re-flow process in use is satisfactory . Wash Processes for Watch Crystals Ultrasonic cleaning should be avoided.
