However this is not enough and we continue to look at other aspects that can not only influence compliance, but also have an impact on the reliability of the product, such as surface finish thicknesses, internal and external base copper along with finished copper thickness for both surface, through holes, microvia holes, cap plating, etc. Granted, I use leaded solder for rework, and therefore ruin the RoHS compliance, but it's rework, so that's not an issue. Animals are the only source of cholesterol, and herbivores do not eat animal products.
