Released on December 14, 2021

Alexa FR4 Plates

Custom cut from high-density and high-tolerance FR4, these Alexa FR4 plates were designed to meet Cherry specifications to 0.025mm on all sides allowing for the perfect switch fitment. Each plate is laser measured prior to finishing to ensure tolerances meet acceptable standards. The unique imported FR4 material used helps to ensure each FR4 plate is free from any warpage during the manufacturing process.
