TinpositTM LF Immersion Tin
The latest in immersion tin technology providing high reliability and solderability for interconnect applications
Advantages
Maintains excellent solderability after multiple lead-free PCB assembly reflow cycles, improving manufacturing process capability and yield;
Outstanding solder joint reliability, resulting from excellent bonding force between PCB pad and reflowed solder paste;
No tin whisker formation, increasing product reliability and avoiding short-circuits between closely spaced circuit features;
Effectively eliminates galvanic corrosion preventing yield loss from circuit breaks;
Significantly reduced attack on solder mask
Tinposit(TM) LF Immersion Tin produces uniform and solderable tin deposits on properly prepared PWB substrates and is specifically formulated to be used in lead-free
assembly processes. The deposits can maintain good solderability after multiple reflow processes. The Tinposit(TM) LF Immersion Tin bath is easy to control and has a high
tolerance for contaminants.
