IC Packaging Capabilities
We provide IC packages in a complex array of shapes, sizes, and materials, giving you the ability to select the exact features and functionality best suited to your specific application. This determination however is dependent upon a number of factors, including: Pitch, Dimensions, Lead Count, Thermal Requirements and Costing.
QFN (Quad Flat No Lead), represents a specific IC Packaging solution. iNPACK offers a customized panel-level solution featuring a plastic-encapsulated laminate panel, with a variety of dielectric and CTE options for electrical interconnection with the PCB. This type of packaging can be offered as a full turn-key solution, (including assembly and testing), or as a stand-alone substrate, combined with cavity lid.

Advantages
Material CTE Analysis
to verify that all materials used in the design of interconnections, substrates and thermal interfaces are certified to match the semiconductor properties.
Fanning Out the I/Os
from 2 or more dies to the substrate, which enables chips with improved performance and more I/Os.
Warpage Inspection
for substrate processes in micro assemblies and post SMT processes. Warpage poses a major risk on front and back-end processes, such as ball shooting, mounting, molding and interconnections.
Interconnect Options
are a critical part of packaging. We offer a wide variety of chip interconnect methodologies used in IC package design with an eye towards continuously improved technologies.
