Supplier 'goes green' to prevent lead-free mix-ups
22 March 2006Manufacturing / Production Technology, Hardware & Services
One of the biggest issues facing electronics manufacturers transitioning to lead-free soldering is the threat of cross-contamination, ie, 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 downtime if they become accidentally combined with lead-free soldering products.
Cobar, a leading supplier of solder pastes and fluxes worldwide, has instituted a simple, recognisable colour-coding standard for all of its solder paste products to distinguish lead-bearing from lead-free. Effective immediately, all its outgoing lead-free solder pastes will be packaged in green-coloured containers such as cartridges and jars, while lead-bearing pastes will continue to ship in white containers.
Says Eli Westerlaken, Cobar president, "Since everyone knows that all solder pastes look very much alike, we want to make it as easy as possible for our customers to prevent cross-contamination during lead-free changeover. Delivery of lead-free paste in green packaging and lead-bearing paste in white will make it easy for the customer to recognise the product and prevent mistakes."

A cordless ESD (Electrostatic Discharge) wrist strap does not work by grounding the person in the same way as a traditional wired wrist strap. Instead, it works by reducing or balancing the static charge on your body so that you are less likely to discharge electricity into sensitive electronic components.
