Through Hole Components: Should a Designer Use Them? Let’s take a look at some of the reasons for using, or not using through hole components in a PCB design. Sometimes that is a really good idea, but there are also times where it is better to use something different. In circuit board design for instance, it’s very easy to use the same through hole components that we’ve always used. All of these enhancements made it a real pain to use, and I was always looking for ways to break it so I could go back to using the old trusty mower again.įor many of us, falling back to something that we’ve always trusted is a normal part of life. The grass clogged the chute, the bag had to be emptied every 30 feet, and it was so low to the ground that it would constantly stall. Then my parents bought us a new mower that was a nightmare. You simply filled the tank, pulled the starter rope, and mowed. Mowing the grass was my job growing up, and I used a plain old gas powered mower without powered wheels, a bag, or any other enhancements.
