One of the biggest issues facing electronics manufacturers transitioning to lead-free soldering is the threat of cross-contamination, i.e., lead-bearing materials become mixed up with new lead-free solders. Even small amounts of lead contamination can cause tremendous problems and result in high remediation costs as well as process down-time if they become accidentally combined with lead-free soldering products.
Cobar has instituted a simple, recognizable color coding standard for all of its solder paste products to distinguish lead-bearing from lead-free. Effective immediately, all outgoing lead-free solder pastes will be packaged in green-colored containers such as cartridges and jars, while lead-bearing pastes will continue to ship in white containers. There is no difference in the quality of the packaging material, only the color is changed.
