We are in the process of performing an analysis on OSP coated boards as an alternative to HASL coated boards. So far everything looks excellent. Outstanding wetting, solderability, less solder bridging issues, better paste printing results, better component placement results, better match of pad geometry with gerber data, no bow and twist problems, flatter board surface, etc., etc..... However our Manufacturing manager is concerned with the following issues: 1. Moisture Sensitivity 2. Scratches through the OSP coating 3. Finger print sensitivity 4. Stricter Handling requirements Will the boards have to be vacuumed sealed with desiccant to prevent moisture damage? How sensitive are the boards to finger prints? What is the typical shelf life of an OSP coated board? If the boards are scratched through the OSP coating will we have soldering problems later? Is there a contact person at Enthone (our supplier used ENTEK OSP coating) who could help me with some of this? These are just a few questions that need to be addressed, and any response regarding this matter will be greatly appreciated. Thanks in advance for your help!
