80 PCB007 MAGAZINE I SEPTEMBER 2021 3. Product Rating 2: (Acceptable, provided that solderability requirements are met); defects and frequency greater than Product Rating 1 but less than Product Rating. 4. Product Rating 3: (Non-conforming;) More than 40% of locations showing Level 3 defects. With the issuance of 4552A and 4552B there is now a way to quantify nickel corrosion. It is the author's experience that the availability of a quantifying method is already paying great dividends, as the occurrence of the defect is al- ready showing signs of coming under control. OEMs or buyers can now specify acceptable levels of corrosion and the manufacturer and supplier have to make the required changes to meet those levels. Presently, Subcommittee 4-14 is subdivid- ed into subgroups, each with its own chair and vice-chair to address a single finish; for example, an OSP committee and an EPIG committee, etc. All committee work is voluntary from partic- ipation in meetings to manufacturing test ve- hicles and testing. Companies allow their em- ployees to spend time in committee work and these companies must be credited for the suc- cessful issuance of IPC specification. e au- thor urges all industry personnel to sign up and participate in committee work in the areas of their interest. You will learn a lot by commu- nicating and collaborating with other members and more importantly, you will give back to the industry and to the community at large.
