Creep Corrosion On Lead-Free Printed Circuit Boards In High Sulfur Environments

The material and process changes required to eliminate lead from electronics as required by Restriction of Hazardous Substance (RoHS) legislation was likely to result in new quality and reliability issues. The industry had over 50 years experience with tin-lead solders. Changing to different solder alloys, fluxes, termination plating materials, PCB surface finishes and soldering temperatures ...

Understanding Creep Corrosion Field Fails

However, creep corrosion is a mechanism by which electronic products fail in application, primarily related to sulfur pollution present in the air. The sulfur reacts with exposed silver, and to a lesser extent, exposed copper. This paper will explore various aspects of the creep corrosion chemical reaction

Heller Reflow Oven -- I am planning to purchase a Heller Reflow Oven. It is a Sept 1996 make, Model # 1088. It is in good working condition. Would like to know if spares would be available for this old model machine? Also, what would be a fair price for this machine?

Q on Yamaha P-tools -- Hi. New to P-tools for Yamaha YV88X use. Just created the line1 -> machine1 details -> appear to be able to create fresh board data but doing so manually. Is it possible to import in VIOS text formatted CAD data into this tool ? That is, import in the CAD2CAD exported file so that we can review and modify as needed inside of P-tools ? Unable to locate any import function as of this writing. Did try to import the VIOS formatted files from Synergy (ie. ATMEL demo project) but P-tools does not appear to recognize the file for importing. A fresh board created using this tool can be loaded and is linked to the selected machine (YV88X). Thanks.
