Issues may be caused on copper foil due to unexpected elements in manufacturing process such as dent, scratch, resin point, wrinkle, pinhole, bubble etc. All those problems will definitely lead to low performance of CCL and then PCB.
Heavy Copper and EXTREME Copper in PCB Design for Maximum
Circuit layers start as thin sheets of copper foil (generally 0.5 oz/ft 2 to 2 oz/ft 2) that are etched to remove unwanted copper, and plated to add copper thickness to planes, traces, pads and plated-through-holes. All of the circuit layers are laminated into a complete package using an epoxy-based substrate, such as FR4 or polyimide
Important Update on Copper foil Shortage – Your PCB
Copper Foil; Important Update on Copper foil Shortage. one of the world’s main suppliers of PCB laminate recently stated: “The copper foil shortage has resulted in approximately 2.8M sheets per month of Copper clad laminate global material shortage. This is approximately 2X the total rigid demand of USA and Europe combined.
