SOT-23 Component Tinning

Our robotic hot solder dip (RHSD) component tinning services are used to change the metallic finish of SOT-23 devices, most commonly to convert the metallic finish from lead free to leaded (Sn63/Pb37) for tin mitigation applications. Our RHSD service can also be used to process SOT-23's that require gold plating removal for gold mitigation applications.

We use fully programmable robotic hot solder dip (RHSD) machines to precisely control dip depth, dwell times and temperatures for processing of components in full compliance with GEIA-0006 standards. This highly automated, tightly controlled process ensures that 100% of the tin finish is removed and replaced with tin-lead (Sn63/Pb37).

Gold removal/mitigation is completed in accordance with J-Std-001 specifications.

We use batch wash systems for post process cleaning, provide tape and reel services, component MSL bake and packaging and pre/post process testing as needed.
