2025 World Record 124 Layer PCB Imagine designing, fabricating, and assembling this beast… OKI Circuit Technology just dropped a 124 layer PCB shattering the long standing 108 layer ceiling, all while keeping the board thickness at just 7.6 mm or 0.299 inch. As a PCB designer, think about what it would take to even route that. As a fabricator, think about the tight registration, handling, via reliability, and thermal integrity needed across 124 layers. As an EMS provider? Good luck...

Gold Plating PCB: Complete Guide to Types, Benefits & Process Hard gold plating is an electroplated surface finish that deposits a durable gold alloy coating onto specific PCB areas, providing exceptional wear resistance and electrical conductivity. After working with circuit boards for over a decade, I can tell you that choosing the right surface finish […]
