FEATURES

PCB Design
Designing for High Layer Count
The design team plays a major role in reducing emissions, increasing immunity and improving signal quality for complex, high-speed PCBs.
by Faisal Ahmed and Ishtiaq Safdar

Design Constraint
Next Generation PCB Design Constraint Management
New design systems support multiple users and concurrent rules - and they automate repeat tasks and use net topology templates - to reduce the time needed to complete complex designs.
by Andy Critcher

Quality Systems
The Use of Six Sigma Principles for Successful RoHS Implementation
The change over to lead-free creates an excellent opportunity to evaluate new materials and upgrade manufacturing processes that will result in improved quality and a lower manufacturing cost.
by Dr. Sammy G. Shina

Better Business
Transforming the Chemical Supply Chain
Chemical management services offer a new business model that can reduce cost and keep companies compliant with evolving regulatory challenges.
by Jill Kauffman Johnson

PTH Metalization
Metalization of High Performance Resin Materials with a Graphite-based Direct Plating System
Graphite systems coat and then bind to resin and glass, making them ideal for use with a wide variety of high performance laminate materials.
