Abstract:
A screen printing fixture holds a flexible circuit board having components attached to one side, to allow screening a pattern of solder paste onto the second side for subsequent attachment of components to that side. In an electronic package assembly a flexible circuit board with components is wound about a heat spreader assembly having a cavity so that at least one component on the flexible circuit board is positioned within the cavity and in thermal connection to the heat spreader.
