Abstract:
A method for designing structures with complimentary dynamic warp characteristics for attachment of a component to a PC board is disclosed. The method may include determining characteristics of thermally induced dynamic warp of the PC board and of the first component, analyzing and comparing differences between the dynamic warp characteristics of the PC board and the first component and selecting design modifications to match PC board and the first component dynamic warp characteristics. Selecting design modifications may include determining if the first component dynamic warp characteristics can be changed, determining if matching the dynamic warp characteristics of the PC board and the first component can be achieved by modifying the design of at least one of the PC board and the first component. The result of the method may be modified dynamic warp characteristics of at least one of the PC board and the first component.
