ATLANTA – Lead-free doesn’t seem new, but many myths still pervade industry thinking. One expert tried to dispel them.
In a presentation during the Atlanta SMTA Show Thursday, Chrys Shea, R&D applications engineer manager at Cookson Electronics, posted statements about Pb-free and asked whether the audience thought they were fact or fiction. She made some strong points about the myths of Pb-free, showing a distinct passion for her research. Here are the key points of her presentation:
DANDERYD, SWEDEN – Note AB reported first-quarter sales rose 0.5% to SEK 427.3 million, while net profits fell 53% to SEK 5.7 million.

BANNOCKBURN, IL – IPC has released IPC-7095B, Design and Assembly Process Implementation for BGAs.
This revised document focuses on applications that use both SnPb and Pb-free on the same board, including various solder ball alloys, new laminate materials for Pb-free, BGA trace escape and routing considerations during board design to improve yield and reduce cost,” explained Ray Prasad, task group chairman.
“There is also a detailed discussion of reflow solder profiling, void process indicators and ways to improve product reliability,” he said
The standard was approved by consensus last month, said Prasad, who is also principal of Ray Prasad Consultancy Group, in a statement.
