Heat Generation and Cooling in Photo Chemical Etching and Related Processes

Proper temperature control has always been important for maintaining the best quality control of etched parts. To accomplish this, heating systems are used to raise the processing temperature to a point that is high enough to provide an acceptable operating rate. Once the processing is started, the process temperature may continue to rise, even though the heating system is no longer in operation. To keep the process at the desired temperature, some type of cooling system is needed.
