Product Introduction
The PCB tin plating bath-specific zirconium anode basket is a dedicated anode carrier device designed specifically for the tin plating process of circuit boards. It is made of high-purity R60702 industrial-grade zirconium, precision-cut, formed, and welded in one piece under high-purity argon protection. The basket has uniformly spaced openings to ensure sufficient circulation of the plating solution and achieve uniform dissolution of the tin anode. Unlike ordinary titanium anode baskets, zirconium baskets exhibit significantly superior corrosion resistance to fluoroborate plating solutions, with a service life 3-5 times longer. The product does not release impurity ions or contaminate the tin plating solution, effectively avoiding defects such as haze, pinholes, and reduced solderability caused by titanium ion contamination. It is widely used in PCB pattern tin plating, through-hole tin plating, and lead-free tin plating processes, and is the preferred anode equipment for fluoroborate tin plating production lines.

Product Features and Applications
Product Advantages
Excellent resistance to fluoroboric acid and a lifespan far exceeding that of titanium baskets: R60702 pure zirconium has a stable passivation film in the fluoroboric acid system. Unlike titanium materials, it will not be rapidly corroded by fluoroboric acid ions that destroy the passivation layer. Under normal working conditions, its service life can reach 5-8 years, which is 3-5 times that of ordinary titanium baskets. This greatly reduces the frequency of replacement and downtime costs, resulting in lower overall costs in the long term.
Zero impurity precipitation ensures solderability of the coating: The all-zirconia material comes into contact with the plating solution without precipitating impurity ions such as titanium and iron, which will not cause problems such as plating solution pollution, tin layer fogging, pinholes, and reduced solderability. The coating has high purity and uniform color, and the yield rate is significantly improved. It is especially suitable for lead-free tin plating processes of high-end PCBs, automotive boards, and communication boards.
Precisely adapted to PCB production lines, installation requires no modification: It can match the original titanium basket's shape, size, ear spacing, and suspension height in a 1:1 ratio, and can be used directly by replacement without modifying the plating tank and conductive beam; the ear positions are precisely symmetrical, the suspension is stable and does not tilt, the current distribution is uniform, and the plating thickness of the entire board is guaranteed to be consistent.
Precise mesh matching and high anode utilization: The mesh size can be precisely matched according to the specifications of the solder balls, which not only ensures the full circulation and exchange of the plating solution, but also prevents the solder balls from leaking out and causing waste; it can load solder balls, solder corners, and solder scraps, which greatly improves the utilization rate of anode materials and reduces consumable costs.
High-purity argon welding ensures corrosion-resistant and defect-free welds: Addressing the high-temperature oxidation characteristics of zirconium, a triple-protection welding process using 99.99% high-purity argon gas is employed. This results in dense welds free of porosity and oxidation embrittlement, with corrosion resistance matching that of the base material. This prevents preferential corrosion and leakage at the weld, leading to a more stable overall service life.
Application Areas
PCB manufacturing: pattern tin plating, through-hole tin plating, fluoroborate tin-lead plating, lead-free tin plating production line anode bearing.
FPC Flexible Board: Flexible circuit board tin plating, roll-to-roll continuous tin plating equipment anode material basket.

Professional Consultation Q&A
Q1: Why can't titanium anode baskets be used in PCB fluoroborate tin plating processes, and why must zirconium be used instead?
A1: The core reason is that titanium corrodes and fails rapidly in the fluoroboric acid system. Fluoroborate ions destroy the oxide passivation film on the titanium surface, leading to continuous corrosion and dissolution of the titanium basket. This not only shortens its service life (usually requiring replacement every 3-6 months) but also releases titanium ions, contaminating the plating solution and causing problems such as fogging, pinholes, and reduced solderability in the tin plating layer. In contrast, R60702 industrial pure zirconium has far superior chemical stability than titanium. Its passivation film remains stable in the fluoroboric acid plating solution, exhibiting an extremely low annual corrosion rate and a service life 3-5 times longer than that of titanium baskets. Furthermore, it does not release impurity ions, ensuring long-term cleanliness of the plating solution and coating quality. It is a reliable anode support solution for PCB fluoroboric acid tin plating processes.
Q2: If a zirconium anode basket is immersed in a tin plating bath for a long time, will impurities precipitate out and affect the solderability of the tin plating layer?
A2: No. R60702 pure zirconium is chemically extremely stable in fluoroboric acid and acidic tin plating solutions. At normal operating temperatures, it will not precipitate zirconium ions or other impurities, will not change the composition of the plating solution, and will not affect the purity or solderability of the tin layer. On the contrary, titanium ions precipitated from titanium basket corrosion are a common cause of brittle tin plating and decreased solderability. Our products undergo acid pickling and passivation treatment before leaving the factory, forming a dense oxide film on the surface, further ensuring cleanliness during use and fully complying with RoHS environmental protection and plating quality requirements for high-end lead-free tin plating of PCBs.
Q3: Can you customize a 1:1 scale titanium basket based on the dimensions of our existing PCB electroplating line's old baskets without modifying the tank and conductive beams?
A3: Absolutely. We support 1:1 replica customization based on provided drawings or samples. You only need to provide the length, width, and height dimensions of your old titanium basket, the spacing and dimensions of the conductive lugs, and the height and width of the conductive beams in the tank. We can then precisely match the design, ensuring that the lug spacing, suspension height, and overall dimensions are perfectly adapted to your existing plating tank and conductive system. After installation, it can be used directly with electricity without any equipment modification. We can also optimize the structure based on your specific needs, such as adding reinforcing ribs, optimizing the mesh layout, or adding compartments, improving performance without changing the installation dimensions.
