Take a look at almost any modern electronic device. Whether it's a smartphone, laptop, router, or smartwatch, you'll find dozens—or even hundreds—of tiny rectangular components soldered onto the circuit board.
Many of those components are SMD resistors.
Despite their small size and low cost, SMD resistors are the result of a highly controlled manufacturing process that combines ceramic engineering, precision printing, laser trimming, and automated testing.
Let's take a closer look at how these tiny components are made.
