Import Tips
• Confirm polyimide as the backing material and copper purity as refined; retain supplier certificates for alloy content
• Declare exact thickness measurement method excluding backing to prevent disputes over 0.15mm limit
• Avoid common error of classifying as finished flex PCB; specify as raw clad material only
