Let PCB Shielding Protect Your Design
ByGrace July 1, 2025June 30, 2025
In the 7th century BC, Greek soldiers or heavy infantry carried a large concave circular shield called a hoplon. Made of bronze and wood, the hoplon or Argive shield protected the heavy waist from chin to knees and when overlapped became the basis of the Greek phalanx. In the early 20th century, Ethiopians fought against…
