TINPOSIT™ LF Immersion Tin

TINPOSIT™ LF IMMERSION TIN is an immersion tin formulation producing uniform and solderable tin deposits on properly prepared PWB substrates. The deposits maintain good solderability after multiple reflow processes, and the bath has a high tolerance for contaminants.

Used in:

  • PWB metallization applications, specifically lead-free assembly processes

Advantages:

  • Maintains good solderability after multiple reflow processes
  • Bath is easy to control and has a high tolerance for contaminants
  • Excellent uniformity of tin deposits
