Is a 3-layer PCB cheaper?
3-layer PCBs cost more than 2-layer & often less reliable than 4-layer. Understand hidden manufacturing expenses,thermal risks, & rare use cases before choosing layers.
What Are PCB Laminate Materials?
Choose PCB laminates wisely: Upgrade FR-4 for GHz signals or extreme heat. Prevent delamination/CAF via precise lamination. Balance 6 thickness factors for reliability. Stop failures before power-on.
