Digital Soldering Station: An Integrated Hardware and Software Designing Case Study



  • The Benefit of Temperature Control. Soldering station is a common name for a temperature-controlled soldering system. A term digital is used to indicate that the major processes inside the system are implemented using digital methods: by using digital logic-gates or micro processor/micro controller. A temperature control mechanism make some benefits for soldering: the overheating of the soldered components could be avoided, a soldering tip  with better cohesion (usually has lower melting point) can be used, and faster heating-up can be achieved by using higher wattage without overheating.
  • What We Do. Before writing this report, I have already designed the system in a paper, built the hardware, programmed the software, and tested the result. In writing this report, I am focusing on how I design and how I program, hoping that the reader can follow my method in solving other similar problems.
  • The Motivation and The Goal. The motives of doing these designing and implementation processes, and then writing a report and sharing all of these to the public is nothing more than sharing some knowledge and experience of how to bring theories into practices, encouraging more people to explore what they know and share how they apply their knowledge to solve many problems. The goal of these designing and publication is to produce a usable design, which is publicly available and can be used as a design reference for real production or further development.
