3D) Industry 4.0 and Manufacturing Test Coverage
Will Webb, Astor Technologies
Abstract: In order to deliver Defect Free Products, ASTER is promoting a new vision of Design to Delivery flows, by applying the principles of Industry 4.0 principles. It is named Enhanced Manufacturing Services 4.0 (EMS 4.0). EMS 4.0 can be used as part of an organization’s Continuous Improvement Program, to decrease product development time, production cost and manufacturing cycle-time, while increasing product quality, reliability and ultimately the customer satisfaction.
EMS 4.0 is articulated on two principles:
1) Qualify the customer defect universe using traceability and repair loops (big data analysis). This universe includes not only manufacturing defects, but also design, and functional defects.
2) Simulate the manufacturing flow from schematic or layout file in order to identify the possible consequences of inadequate testability and test coverage on a new design.
Traditionally, manufacturing and test constraints are only considered at the end of the layout phase, just prior to the transfer of CAD data to production. This is too late to have a significant contribution on time to market. With EMS 4.0, TestWay significantly decreases the overall cycle time from the design concept to customer delivery, which is a critical success factor. It makes it possible to implement a Lean Test approach that produces a lower cost product whilst maintaining the highest quality.
Using Digital Simulation, TestWay creates a virtual copy of the physical world. It allows “What-if” scenarios played in the virtual word to identify the optimal physical flow, using theoretical results to control the physical world. The EMS 4.0 workflow enables tremendous benefits in time-to-market, cost reduction and quality improvements.
4A) High Performance Power Packaging with Highly Thermally Conductive Laminates
Doug Hopkins, NC State University
Abstract: The trend to higher performance power electronic systems has fostered more electrophysical integration of microelectronics packaging and assembly approaches. This presentation reviews the new trends in Heterogeneous Integration. A focus on power packaging using thin organic substrates, specifically Epoxy Resin Composite Dielectric (ERCD) materials with thermal conductivities up to 10W/mK is given. The thin dielectrics in the 80-120µm range outperform traditional alumina DBC, allow for embedding of components and layering of power ground planes while maintaining high voltage breakdown voltages (up to 5kV/mm). The thinness of the material may require some special handling equipment depending on feature sizes, such as direct laser imaging for circuits and solder mask. However, for power more conventional fabrication processes, such as copper etching and plating may be sufficient.
This presentation covers material characteristics and new prototyping capabilities at NC State University’s PREES power packaging laboratory. An example design of a power-GaN based integrated power module (IPM) is provided from electrical circuitry, through processing steps to fabrication. The example is concluded with a completed open-source IPM design with electrical test results.

4C) Applications for Embedded NiP Thin Film Resistors in Printed Circuit Boards
Bruce Mahler, Ohmega
Abstract: There has been a growing use of the NiP thin film resistive material as embedded heaters on inner layers of multilayer printed circuit boards. This paper will review the methodology and results of characterizing heat rise vs. power input for resistors of various sizes and sheet resistivities (values). From this characterization process, general design rules can be established for temperature rise vs. power input for specific heater requirements.
This paper will also review a number of heater designs and applications including a patent pending design method for increasing or decreasing the resistor values of heater elements to the nominal values required within constrained circuit areas for the power input and temperature rise of a given application.
4D) Reliability Testing of Faradflex Embedded Capacitance at High Voltage and Temperature
Bob Carter, Oak-Mitsui, FaradFlex Division
Abstract: For high speed printed circuit board designs embedded capacitance is often used. The embedded capacitance materials for printed circuit boards are typically qualified by assessments of assembly survivability and by relatively short term conductive anodic filament testing at 100V or less, 65-85˚C, 85% relative humidity testing for 500 to 1000 hours depending on the application. The tests set a baseline for reliability for typical, lower voltage applications that has served the industry well. To understand the long-term reliability of the embedded capacitance materials, acceleration factors for temperature and voltage need to be developed. Testing at high voltages, 800V, 650V, and 500V, plus high temperatures of 150˚ and 125˚C has been running for over 3.5 years to evaluate the embedded capacitance reliability. As a comparison, 100V rated ceramic capacitors were also evaluated in this testing. The paper reports the results for the 150˚C testing.

6A) BGA’s, LGA’s, QFN/DFN’s – Oh My, Can Traditional DFM Survive
Dale Lee, Plexus
Abstract: Today’s electronic product designs are rapidly increasing the use of bottom terminated components (BTC’s), whether they are collapsible/non-collapsible ball grid array (BGA), solder bump grid array (BGA?), land grid array (LGA), quad-flatpack no-lead (QFN) or dual-flatpack no-lead (DFN) component packaging technologies. However, with some BTC package designs vary greatly in solder pad design and pitch within the same package. This variability impacts the ability to incorporate good DFM practices and selection of applicable assembly workmanship rules for these and other standard BTC component package designs. This presentation will highlight impact elements these component technologies have on the assembly, cleaning and inspection processes and what actions can be made during the DFM and NPI process to minimize yield impacts on the manufacturing process.
