Tin Plating
Services
RoHS-compliant, lead-free tin electroplating delivering excellent solderability, low contact resistance, and corrosion protection for electronics components, food processing equipment, and industrial hardware.
Our tin plating process is fully lead-free and compliant with all current EU and international electronics environmental directives.
100% RoHS & REACH Compliant — Lead-Free
All tin deposits are produced from lead-free electrolyte systems, fully compliant with RoHS Directive 2011/65/EU and REACH SVHC regulations. Full Declaration of Conformity provided for every batch at no extra charge.
Tin Whisker Mitigation Available
For high-reliability electronics, we offer bright tin with annealing treatment and matte tin deposits — both proven to reduce tin whisker growth risk per JEDEC JESD201 guidelines. Whisker evaluation per JEDEC JESD22-A121 available on request.
Alkaline and acid tin plating processes are available, each optimised for different substrates and finish requirements.
Pre-Treatment
Alkaline cleaning, acid activation, and electrolytic cleaning to remove oils, oxides, and ensure a receptive substrate surface.
Tin Deposition
MSA or alkaline stannate bath with precise process control for matte, semi-bright, or bright tin deposits as required by specification.
Reflow / Annealing
Optional reflow treatment at 232°C produces a bright, reflowed tin layer that significantly reduces whisker growth risk for high-reliability electronics.
QC & Solderability
XRF thickness, solderability testing per J-STD-003, visual inspection, and whisker evaluation per JEDEC JESD22-A121 on request.
