Antistatic protection when removing coatings from printed-board assemblies using Borey machine

A New Test Strategy for Complex Printed Circuit Board Assemblies

The trend in Printed Circuit Board Assembly (PCBA) technology is towards higher complexity. Many boards have significantly more components and solder joints today than just a few years ago. More components and more solder joints means more defect opportunities and lower yields. A higher number of components typically means higher cost for each PCBA, resulting in higher WIP cost (work in process...

Printed circuit board inspection

This paper provides a general overview of immediate and long-term aims of the printed circuit board inspection project of The Robotics Institute. Its purpose is to highlight some of the significant issues specific to printed circuit board inspection and to provide a discussion of our basic thesis that machine inspection should be coupled with machine diagnosis of the causes of observed printed ...

Effect of ionic contamination on climatic reliability of printed circuit board assemblies

On the Selection of Parts and Processes during Design of Printed Circuit Board Assemblies

We consider a multiobjective optimization model that determines components and processes for given conceptual designs of printed circuit board assemblies. Speci cally, our model outputs a set of solutions that are Pareto optimal with respect to a cost and a quality metric. The discussion here broadly outlines an integer programming based solution strategy, and represents in-progress work being ...

Effect of Silicone Conformal Coating on Surface Insulation Resistance (SIR) For Printed Circuit Board Assemblies

Conformal coatings are considered a method of providing corrosion protection to electrical assemblies used in high-humidity or harsh environments. They are applied to PCBs for various reasons: to protect from moisture and contamination, to minimize dendritic growth, to provide stress relief, and for insulation resistance. These contribute to more durable handling, enhanced device reliability, a...
