Surrey, UK — At the Southern Manufacturing 2004 Show, the UK's largest regional manufacturing technology, electronics & subcontracting exhibition, held at Thorpe Park, Surrey, on February 18 through 19, National Physical Laboratory (NPL) achieved the highest attendance figures in the electronics section with their lead-free session.
Alan Brewin from NPL presented "Reliability Issues with Lead-free Soldering," the high attendance again proving that lead-free is the hot topic of the moment. Brewin covered a range of concerns, including soldering at high temperatures using different materials, raising a number of reliability and component robustness issues. These were discussed and compared with respect to existing tin-lead processes. After the presentation, a number of delegates lined up to discuss their personal concerns, seeking further advice.
Brewin also presented a session entitled "Are Your Process Residues at an Acceptable Level?" confirming the increasing need to qualify process residues, the progress made in developing techniques and their use to predict reliability.
