2/1/2015 TEB Update

What I accomplished this week

  • Finished moving into the new office
  • Ordered the rest of the equipment and tools needed to complete my research
  • Populated the PCB with all the surface mount components. The process is as follows
    • Apply solder paste to component pads
    • Using tweezers, place components onto pads
    • Preheat oven to 400 degrees Fahrenheit
    • Place PCB in oven and wait a few minutes until you see the components ‘pop’ into place
    • Remove PCB and inspect joints. Use solder wick to remove solder if there is excess amounts and/or solder bridges
    • Clean PCB of remaining flux using toothbrush and isopropyl alcohol

Problems

  • Accidentally snapped a pin off the slide switch which rendered it as useless so I had to purchase more

Next week’s work

  • Solder the slide switch, push buttons and headers to PCB
  • Test PCB for functionality (Any fried components or smoke coming from PCB?)
  • Conduct electrical measurements using multimeter

Below is an image of the board for prototype 1.2

About sylvestre

My name is Jason Sylvestre and I am currently a freshman studying Electrical Engineering here at UW-Madison.  While in high school, I was very involved in search and rescue robotics research and competed at the Intel Science and Engineering Fair where I received a third place medal out of nearly 1800 students from over 70 different countries.  This passion I developed for circuitry and EE brought me to the Living Environments Laboratory where I will be working under the supervision of Professor Kevin Ponto to build a thermoelectric bracelet that can be used for personal thermal comfort.
