3. Customer Demand
The WIT HOT IRON sales team has requests from customers to use the Model 2001 soldering iron on their automated assembly line.
The marketing department has determined that sale orders & revenues could increase significantly. The increased work load could be handled with 3 new employees.

5. Design Features Desired
The soldering iron will be used in an automated assembly line process.
The operator of the iron will be at a remote location.
The temperature of the iron is required to be at 300oF +/- 10oF

14. Next Steps
Use the Internet to research information on relays and sensors.
Include in your memo the source of your information.
The memo might well exceed one page.
Utilize the one-page handout to guide you.
