Tin & Tin-Lead plating and stripping
Tinposit™ Immersion Tin is a tin deposition product, which produces uniform, smooth tin deposits on copper and copper-based alloys by an immersion reaction. Ronastan™ is an acidic tin plating solution which produces smooth, fine-grained deposits over a wide plating range. Ronastan™ deposits are designed for use as etch resists in the manufacture of PCBs, with excellent throwing power and metal distribution, even in high-aspect through holes and microvias.
