A Silicon-to-System Thermo-Mechanical Review of Electronics
A Silicon-to-System Review of Thermo-Mechanical Considerations in Electronics
Author: Kamal Karimanal, Cielution LLC
Thermal and Mechanical challenges to IC package reliability has been addressed with a sufficiently working system of information exchange across a supply chain that spans the foundries to system level assembly plants.The never ending market demand for miniaturization, performance, functionality and cost reduction invariably translates to manufacturing, design, assembly, and reliability challenges to the engineer. Within the Thermal and Mechanical realm these challenges manifest to the engineer in the form of seemingly disconnected problems areas such as BEOL yield, flipchip interconnect reliability, warpage mitigation, heat sink retention design, interface choice, thermally aware board and chassis layout, fan sizing and system level optimization. Evolving technology also introduces newer puzzles such as heterogeneous packaging using 3D ICs. The talk will focus on the tools, methodologies and information exchange protocols used by the thermal management and mechanical reliability professionals across the supply chain to address the various challenges.

Cable Sizing Calculations
This document discusses cable sizing calculations and techniques. It explains that proper cable sizing is important to ensure efficient, safe and economic transmission of electrical energy without interruptions or exceeding the cable's limits. The document outlines the common steps for cable sizing: 1) gathering data on the cable, load and installation conditions, 2) determining the minimum size based on current capacity, voltage drop, temperature rise and fault impedance, and 3) selecting the optimally sized cable. Several examples are provided to illustrate implementing the cable selection process. Risks of improper sizing like voltage drops, overheating and shorter lifespan are also summarized.

Bus duct fabrication
Bus ducts are used to carry high currents between generators and transformers in power stations. They use thick aluminum conductors that are enclosed in aluminum to safely carry large currents up to 20,000 amps. Aluminum is used as the conducting material due to its lower cost compared to copper. There are two main types of bus ducts: isolated phase and segregated phase. Isolated phase ducts have each phase conductor enclosed separately while segregated phase ducts house the three phases together with insulating barriers between them.
Extreme Copper PCB Capabilities
An increasing number of power electronics products are taking advantage of a growing trend in the printed circuit board industry: Heavy Copper and EXTREME Copper Printed Circuit Boards.
Most commercially available PCBs are manufactured for low-voltage or low power applications, with copper traces or planes made up of copper weights ranging from 0.5 oz/ft2 to 3 oz/ft2. Heavy copper PCBs can have more than five times that copper weight, and EXTREME copper PCBs can range up to 200 oz/ft2.
This video discusses design considerations unique to this product as well as how much current these boards can carry. The minimum conductor width and spacing and cost trade-offs for the different techniques will also be covered.

Karimanal ectc 2013_chipstacking_final presentation
A memory stack on logic 3D IC stack was considered for comparative study of warpage response to two different process choices, namely, Die to Die (D2D) and Package to Die (P2D) assembly. Process and reliability modeling software CielMech, and Commercial Finite Element Analysis (FEA) software ANSYS Mechanical were utilized to simulate thermo-mechanical effects of sequential chip attach, underfilling and encapsulation process steps for the chosen flows. Warpage at room temperature as well as attach temperature after each attach step were compared. Results indicated that underfill, substrate, and mold compound thermal strains play important roles in warpage evolution. Significant differences in the final assembled state warpage was predicted and is attributable to path dependence of warpage evolution.
