Given the higher purchase prices and the processing costs of both the solder and the PCB, it is only natural to assume that converting an assembly to comply with the RoHS directive will make it more expensive. However, this is not necessarily true. Cost is influenced by a number of factors, including PCB area, component package type, component availability and circuit density. In many cases, legacy products can be cost-reduced when converted to meet RoHS requirements.
This paper reviews four case studies of non-RoHS compliant product conversions, ranging in complexity from simple updates to complete redesign. Each case presents different challenges and opportunities. Cost reductions range from near-breakeven to over 50%. Different conversion strategies are presented, and the methods of cost reduction are discussed in detail.
