ALPHA OM-338 PT lead-free no-clean solder paste is said to offer unparalleled pin testability, while allowing high print speeds and delivering excellent throughput and yield.
 
“Lead-free pastes have an inherent difficulty with pin test yields… [but] OM-338 PT has proven to be a very promising innovation,” said Mitch Holtzer, global product manager. “Alpha OM-338 PT is targeted to both EMS and OEM customers using in-line circuit testing. It was developed to reduce the number of false negatives recorded when pin probes are used, resulting in increased throughput and yield.”
 
In addition to excellent pintestability with virtually no residue on pins, it offers high print speeds (up to 150 mm/sec., on 12 mil squares and 10 mil circles), compatibility with both Rheopump and Pro-Flow, electrical reliability (passes IPC, Bellcore and HP requirements), clear, colorless flux residue yielding excellent joint appearance, and low voiding and anti-slumping characteristics.
