Tinning Services, Connectors, Pins, and Terminals

Circuit Technology Center provides RHSD tinning for through-hole connectors, pins, and terminals, converting finishes for tin whisker and gold mitigation per GEIA-0006 and J-STD-001. Full post-process cleaning, testing, and MSL packaging included.
Tinning Services, Connectors, Pins, and Terminals

Circuit Technology Center offers precision robotic hot solder dip (RHSD) services to refinish the metallic leads of through-hole connectors. This process is most often used for tin whisker mitigation, where lead-free finishes are converted to leaded (Sn63/Pb37). RHSD is also an effective solution for removing gold plating from through-hole and radial connector terminations.

Our RHSD systems are fully programmable to deliver tightly controlled processing parameters—including dip depth, dwell time, and temperature—ensuring consistent, high-quality results. All operations are performed in full compliance with GEIA-0006 standards to guarantee complete removal and replacement of the original finish.

Gold mitigation procedures are executed in accordance with J-STD-001 specifications. Post-process cleaning is conducted using batch wash systems.

We also provide related services such as tape and reel packaging, MSL dry bake and moisture barrier packaging, and pre- and post-process testing as required.

In-house post-processing testing capabilities include:

  • Ionic cleanliness (ROSE) testing per IPC-TM-650-2.3.25
  • XRF for alloy composition and finish thickness per JESD 213
  • Solderability testing per J-STD-002
  • Visual inspection

Other available testing services include:

  • SAM (scanning acoustic microscopy) testing per J-STD-035
  • Destructive physical analysis (DPA) per MIL-STD-1580
  • Hermeticity testing (fine and gross leak) per MIL-STD-883
  • Temperature, humidity and bias testing
  • Parametric testing

Component Marking and Packaging Services include:

  • Tape and Reel service per EIA 481
  • Component MSL dry bake per J-Std-033
  • Component MSL packaging per J-Std-020
