Solving Operational Challenges during Printed Circuit Board Assembly (PCB) New Product Introduction
Problem Statement: PCB Designs are sent to manufacturing using multiple files of different formats zipped together. This
introduces many errors due to limited project visibility at each stage of manufacturing adding to overall scrap cost.
Reason: The Manufacturing of a complete Electronics Assembly – require the participation of various specialized manufacturers.
(1) The tools used by each of the manufacturers for viewing design data is different hence they do not have complete visibility.
(2) License cost of Tool used by each vendors are expensive hence not
business feasible to acquired by each vendor.

Different Manufacturers and their Data Requirement
Solution: Use a single XML tool which contains all data PCB fabrication, PCB assembly and test data instead of maintaining
multiple data formats like GenCAM and ODB++. XML files can be opened using applications available in open source. The overall
data shared will give visibility to participants at each stage.
Advantages: Prevent operational and technical disparities between the participating organizations. Enhances Project Visibility in
overall value chain. Reduced Operational Costs(elimination of licensed tools). Enhanced product throughput.
Risk : Complete design data is supplied to each participating vendor hence possibility of intellectual property infringement is high.
Mitigation possibilities: Trust and bond between the partner organizations.
Enforcing strong IP infringement laws.
