PCB Eyelets

Ever wonder how components on a circuit board stay connected from top to bottom? Often, it's a tiny metal ring called a PCB eyelet. At Nuote Metals, we make these precision components for electronics manufacturers who need reliable, consistent through-board connections.

A PCB eyelet is a small, hollow tube, usually brass or copper, that gets inserted into a drilled hole on a circuit board . Once in place, the ends are flared or "set" to create a permanent, conductive pathway between layers . They serve two main purposes: mechanical reinforcement and electrical connection .

Before plated-through holes became common, eyelets were the only way to make reliable connections on double-sided boards . They prevent the copper foil from peeling during soldering or repair work. Even today, they're used in high-current applications, power supplies, and boards that need extra durability .

Why choose Nuote Metals for PCB eyelets? Because precision matters in electronics. A poorly made eyelet can cause intermittent connections or solder failures that are nearly impossible to track down . We make ours with consistent inside diameters, clean barrel lengths, and the right plating—usually tin over brass or copper—to ensure good solderability and long-term reliability .

We produce PCB eyelets in standard sizes like 1mm, 2mm, and 3mm diameters, and we can customize lengths to match your board thickness. Materials include brass for general use, copper for maximum conductivity, and tin-plated options for easy soldering .

If your circuit boards need tough, reliable through-hole connections, our PCB eyelets are built for the job. At Nuote Metals, we keep quality consistent so your boards stay connected—batch after batch.
