FSM Cookbook

Technical Library | 2001-04-24 10:41:53.0

Tau models describe the timing and functional information of component interfaces. Timing information specifies the delay in placing values on output signals and the timing constraints (set-up/hold, pulse-width) on input signals of a component. Functional information, through a finite state machine (FSM), specifies when output signal values change, when input signal values are latched, and how output values are determined as a function of input values.

SMT chip capacitor resistor storage and processing method

Technical Library | 2022-04-27 01:34:43.0

SMD capacitors and resistors have small sizes and many models. Some manufacturers buy a lot of products and do not use them up in time. The problem of storage is always a headache. So how should chip capacitors and resistors be stored? There are also precautions when using chip capacitors. Please see the following information and hope it will help you.

Joule Heating Effects on the Current Carrying Capacity of an Organic Substrate for Flip-Chip Applications

Technical Library | 2009-07-22 18:33:41.0

This paper deals with the thermal effects of joule heating in a high interconnect density, thin core, buildup, organic flip chip substrate. The 440 μm thick substrate consists of a 135 μm thick core with via density of about 200 μm. The typical feature sizes in the substrate are 50 micron diameter vias is the core/buildup layers and 12 micron thick metal planes. An experimental test vehicle is powered with current and the temperature rise was measured. A numerical model was used to simulate the temperature rise in the TV.

An Effective Design of Experiment Strategy to Optimize SMT Processes

Technical Library | 2010-04-22 14:55:51.0

It is now widely accepted that using designed experiments is the most effective way to optimize surface mount technology (SMT) processes. This situation begs the question "what is an effective strategy in implementing this powerful tool?" This paper will present such a strategy that incorporates Taguchi's approach for screening, full factorial analysis for optimization and central composite design for precise modeling. We will present these techniques using MINITABTM Release 13 statistical software and printed circuit board industry applications.

Conductive Anodic Filament: Mechanisms and Affecting Factors

Technical Library | 2021-07-27 14:49:16.0

Conductive anodic filament (CAF) formation, a failure mode in printed wiring boards (PWBs) that are exposed to high humidity and voltage gradients, has caused catastrophic field failures. CAF is an electrochemical migration failure mechanism in PWBs. In this article, we discuss CAF, the factors that enhance it, and the necessary conditions for its occurrence. Published studies are discussed, and the results of historical mean time to failure models are summarized. Potential reasons for CAF enhancement solutions are discussed, and possible directions in which to develop anti-CAF materials are proposed.

Electrochemical Sensors

Technical Library | 2022-01-19 17:25:29.0

Electrochemical sensors are a class of sensors in which the transducer component is the electrode. These methods are presently utilized in a wide assortment of business applications. These sensors are significant for some factors: the utilization of the electron for signal obtaining, which is known to be a perfect model for logical applications, without squander age; scaling down in versatile gadgets (test microvolume investigation); quick examination; and minimal effort of creation, permitting these techniques to be promoted (for example as business glucose sensors).

Proof is in the PTH - Assuring Via Reliability from Chip Carriers to Thick Printed Wiring Boards

Technical Library | 2007-06-06 15:25:30.0

Though today's microvias and high aspect plated through holes (PTH's) look nothing like the earliest through holes of 40 years ago, the PTH in its various forms remains the “weak link” and most critical element of printed wiring boards and laminate chip carriers (...) The paper outlines an approach to evaluating PTH reliability and quality that involves characterizing PTH life across a range of temperatures to reveal intricacies not seen by testing at a single delta-T, and certainly difficult to predict by modeling alone.
