Question 13 of 13
Find a printed circuit board with soldered components on it, and bring it with you to class for discussion. If you have access to a scrap bin from an electronics or computer repair shop, this would be an excellent place to find a printed circuit board. On your PCB, try to identify:
- • Number of layers on board
- • “Traces”
- • “Lands”
- • Cold solder joints (if any)
- • Solder bridges (if any)
Reveal answerNothing to answer here!
Follow-up question: be sure you know what each of these terms (“trace”, “cold solder joint”, “solder bridge”, etc.) means.
Notes:The purpose of this question is to get students to kinesthetically interact with the subject matter. It may seem silly to have students engage in a “show and tell” exercise, but I have found that activities such as this greatly help some students. For those learners who are kinesthetic in nature, it is a great help to actually touch real components while they’re learning about their function.
