Discreet SMT Device Tinning

Our robotic hot solder dip (RHSD) component tinning services are used to change the metallic finish on the terminations of discreet SMT devices such as capacitors and resistors, 0603 size and up, 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 SMT discreet devices 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.
