Tin Whiskers Studies

Tin whiskers are individual crystals of tin that grow in a needle-like fashion from tinned surfaces. Such growths can cause electrical shorts by bridging adjacent components or connectors. The following studies analyze tin whisker growth in electronic systems.

Tin Whiskers Study Part I

The implications of tin whisker growth in Navy electronics are examined.

Tin Whiskers Study, Part II

Failure predictions due to tin whisker growth are analyzed.

BGA Repair for Mixed Assemblies

As companies implement lead-free technologies and use different metallurgies, the electronics industry must learn to work with mixed solder technologies. BGA devices are especially sensitive to mixed solders in the rework process

Implementing a Lead-Free Evaluation or Certification Test Plan

Implementing lead-free solder processing often requires evaluation of solder materials or certification of the assembly process. With the seemingly endless number of variables, including solder alloy, reflow profile, aperture reduction, flux types, and component finishes, certification can become an unnecessarily arduous ordeal.
