Polymers in Electronic Packaging: Fan-Out Wafer Level Packaging Part Three
In this post we return to polymers in electronic packaging. In October there were two electronic packaging conferences. The International Microelectronics Assembly and Packaging Society (IMAPS) national conference was held in Pasadena, CA on October 8-11. The second conference was the International Wafer Level Packaging Conference (IWLPC) which is held every year in San ... [Click to Continue...]
Thermoset Cure Kinetics Part 14: Analysis of Autocatalytic Systems from Conversion and Rate of Conversion Data
Guest Post by Dr. R. Bruce Prime and Dr. John Avila In this post we illustrate the p1 form described in Part 11 of this series by fitting conversion – rate of conversion data to a phenomenological equation based in chemical kinetics that is commonly used to describe autocatalytic cure kinetics. Such data can be measured by DSC although in these examples we generate the data ... [Click to Continue...]
Thermoset Cure Kinetics Part 13: Modelling the Effect of Stoichiometry on Autocatalytic Cure Kinetics
Guest Post by Dr. R. Bruce Prime and Dr. John Avila This post explores how the epoxy-amine stoichiometry can affect the cure path of autocatalytic cure reactions, providing additional insight into the behavior of epoxy-amine thermosets. We illustrate some interesting benefits as well as precautions of altering the stoichiometry. For a variety of reasons it is not uncommon for ... [Click to Continue...]
Thermoset Cure Kinetics Part 12: Modelling the Effect of Adding Catalyst on Autocatalytic Kinetics
Guest Post by Dr. R. Bruce Prime and Dr. John Avila In this post we explore how adding an external catalyst or accelerator to increase the reaction rate can affect the cure path of autocatalytic cure reactions, providing additional insight into the behavior of epoxy-amine thermosets as well as commenting on some of the pros and cons of doing so. We show how added catalyst can ... [Click to Continue...]
