Asterion offers both bright acid tin and matte tin finishes. Both offer the reliability, economy and ease of use provided by all Asterion products
Bright Acid Tin
Asterion offers bright acid tin processes that provide brilliant, dense, highly leveled, bright deposits. The brightener system is stable upon standing. The system produces a bright deposit over a wide range of current densities. Temperature variation is not problematic as the process operates over a wide range of temperatures. Likewise, metal concentration ranges are very wide. The process is easy to control with the brightener added on an amp hour consumption basis.
Exception Bright Acid Tin
Asterion offers an exception bright acid tin process which provides uniform brightness in an easy to use two component system. The brightener system is stable and effective over a wide range of operating conditions. The system performs well in both rack and barrel operations. The Asterion Bright Acid Tin Process features rapid plating rates with superior low current density performance. The deposit provides excellent solderability and reflow.
Matte Acid Tin
Asterion offers a high performance matte acid tin process which produces a highly uniform and pearlescent deposit. The single component system is economical and easy to use. A rapid plating rate produces uniform results over a wide range of current densities. The brightener allows many substrates to be processed in the same bath. The same process may be used in both rack and barrel operations with similar results. The deposit exhibits superior solderability and may be re-flowed into a bright finish.
