Soldering Assignment


The soldering assignment is a basic soldering exercise that ensures all ECE 445/ME 470 students understand how to solder surface-mount and through-hole devices. Students will be provided with the necessary PCB, components, solder, flux, etc. The details of the soldering assignment can be found in the assignment sheet.

Your end product should look similar to the following. You will create a small device that blinks an LED at varying frequencies when the button is pressed, based on a potentiometer reading.

Below is a series of soldering tutorials. The critical ingredient that you need to make your life easier while surface mount soldering (and through-hole too) is flux. There is liquid, water-soluble flux available in the lab. If you can't find it or don't know what it looks like, ask a lab staff member or TA for help.

Requirements and Grading

The soldering assignment is worth 10 points and is graded via inspection by a TA or Lab Staff member. Students are allowed to make as many attempts as necessary to complete the assignment.

Submission and Deadlines

The soldered PCB must be presented to a course staff member before the deadline listed on the Course Calendar.

Video Tutorials

Below are a few public video tutorials on Soldering. There is also a text description of how to solder on the soldering assignment doc linked above.

Environmental Sensing for Firefighters

Featured Project

Hyun Yi, Lauren White, and Andri Teneqexhi earned the Instructor's Award in the Fall of 2013 for their work on the Environmental Sensing for Firefighters.

"Engineering is all about solving real life problems and using the solutions to improve the lives of others. ECE 445 allows you to actually delve deeper into what this really means by providing students the chance to undergo the engineering design process. This requires taking all of the theoretical knowledge, lab experiences, and ultimately, everything that you have ever learned in life, and applying it to your project. Though, there is structure to the course and deadlines in place to measure your team's progress, the actual design, implementation, and success of your project is all determined by you. Unlike any other course that I have taken, I've gained an appreciation for the utilization and benefits of external resources, unforeseen scheduling delays, delegating tasks, and most importantly, teamwork. I consider ECE 445 to be a crash course into real life engineering and a guide to become a successful engineer." -- Lauren White
