In the $100B semiconductor test market, the most valuable real estate isn't on a chip—it's in the socket that touches it. Plastronics, a $9.5M revenue powerhouse hidden inside Smiths Interconnect, has quietly perfected the art of making that connection, selling burn-in test sockets and patented spring probes to the industry's biggest players.

"They don't compete for clicks—they compete for wafer starts. Their website traffic is zero, but their market impact is absolute."

• H-Pin technology bridges the cost-reliability gap in semiconductor test sockets
• Smiths Interconnect's brand strategy keeps Plastronics focused on engineering, not marketing
• 43 employees generate $9.5M revenue—$220K per employee—indicating deep technical moats
• Zero digital footprint suggests a relationship-driven enterprise sales model

The tech stack tells another story: jQuery, Bootstrap, OpenCart—tools from a decade ago, not a modern startup. This isn't a tech debt problem; it's a strategic choice. When your primary interface is a custom connector for a specific semiconductor test cell, your website is just a digital business card. The real innovation happens in their labs, where H-Pin contacts undergo stress testing that would make a Silicon Valley startup flinch.
