The Main Cost Factors for Paper Leadframe is the Paper Thickness, Paper Material and the Stamping Tool.
Paper Thickness: This thickness is required to be thicker than the copper leadframe or the PCB substrate, we have our own proven processes to laminate multiple payers of paper to achieve the required thickness. On cost factor, usually the unit cost of a Paper Leadframe for a 0.15/0.20mm thick Leadframe or Substrate ranges from US$0.10-0.20 each depend on the length and width; the unit cost of a Paper Leadframe of >0.5mm thick Leadframe or Substrate is at >US$0.30 each.
Paper Material: The quality of the material is dependent on the heating and pressing process before cutting, we have mastered this know-how and can ensure high heat endurance and minimum paper warp. This special processes adds cost to the Paper Leadframe but it is absolutely needed to ensure quality and performance.
Stamping Tool: The cost of a stamping tool can range from US$0 to US$20,000; zero cost when it is an open tool but the customer still needs to pay for the refurbishment cost every year. This cost is either paid out-front and enjoy a standard leadframe price or is amortised into the unit price of the leadframe. There is no real “free tool”.
