October 16, 2014 – When I meet people in the electronics industry and tell them I am the Marketing Manager for through-hole products at Universal Instruments, they almost always say “You still sell those machines? I thought through-hole technology is DEAD”. I inform them that through-hole technology is still alive and has a very important place in our current high-technology world. There are many uses for through-hole components in our ever-shrinking electronics landscape.
For example, how would you charge your cell phone, tablet, laptop or other battery-powered portable devices without through-hole technology? That Power supply that you plug into the outlet contains mostly through-hole components to keep the cost down and reliability up. After all, what good is an expensive smart phone if your charger is dead and cannot charge your phone?
How about those nice LED signs you see on buildings, billboards and sports complexes? They contain hundreds of thousands of through-hole LEDs. They are used because the LED is very bright so you can see it in direct sunlight and sealed so the sign can take whatever mother nature can throw at it and sill work for more than 10 years.
Another example is power supplies and power controllers used in industrial equipment. This equipment is very rugged and can take a beating and keep on working. Industrial equipment can generate a lot of heat and consume a lot of power. Through-hole components are built tough and available in much larger sizes capable of handling the substantial heat and power requirements of industrial equipment.
So these are three very good examples of the importance of through-hole in modern technologies, proving that it’s not just surviving but thriving in today’s high-tech world.
