摘要
The limited routing capabilities of available substrates for space-limited complex circuits force a cost-performance trade-off for dense circuit designs incorporating high lead count devices. 3M Laminated Micro Interconnect (LMI) technology offers high performance, dense routing in a flexible polymer film package which is compatible with flip chip solder reflow or conductive adhesive die attach techniques. In this paper we discuss the basic LMI construction and contrast it to conventional built-up multilayer approaches. LMI Design Rules and routing capability are illustrated by a GPS receiver test vehicle. The environmental reliability of the LMI structure is characterized with data from Daisy Chain and Kelvin structures built into LMI test vehicles.
