Our tinning or re-tinning services are used to change the metallic finish of component leads or pads, most commonly to change leads or pads with a lead-free solder finish to a leaded solder finish for tin whisker elimination. Tinning is also used for gold plating removal or mitigation.
We use a fully programmable robotic hot solder dip machines (RHSD) to precisely control dip depth, dwell times and temperatures for processing of components in full compliance with GEIA-0006 standards. When required, 100% removal of tin finish is replaced with tin-lead (Sn63/Pb37) for tin whisker mitigation.
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.
