CXH SERIES-Outrigger Product Expansion Qualification Test Report

2021-01-13

The CXH outrigger Series is a resistive product that is designed to handle more power than the conventional flip chip resistor. The power increase comes from the SINT patented design with added ground bars to the sides of the chip to dissipate more heat as shown in figures 1 and 2.
The two ground bars in figure 2 create two more thermal paths to ground which allow the resistor to dissipate more power. The 2 outriggers function as heat spreaders that dissipate approximately 50% more power than conventional flip chip resistor.
Currently Smiths Interconnect offers an equivalent 0402 chip and 0603 chip on Alumina for the both the single and dual CRH outrigger series layouts. A single and dual CRH outrigger series product shown in figure 3. The single outrigger will only have one added ground bar instead of two. The goal of this project is to expand on this existing line to create a 0805 and 1206 equivalent CRH outrigger series on Alumina ceramic and create an ALN ceramic version for increased power handling for all 4 chip sizes(i.e. 0402, 0603,0805, 1206 equivalent). The below report will explain in detail what test were done to qualification these new products.
