NB SEMIPLATE AU 100 TL
Our Gold Plating Solution without arsenic
! PRODUCT NAME CHANGE !
Old Name: NB Semiplate AU 100 TH
New Name: NB Semiplate AU 100 TL
NB SEMIPLATE AU 100 TL is an alkaline, non-cyanide electroplating formulation which produces a matte to semi-bright, ductile deposit. While the NB SEMIPLATE AU 100 product contains arsenic for achieving shiny deposits, the NB SEMIPLATE AU 100 TL is based on thallium and free of arsenic. In comparison with other gold plating processes, the NB SEMIPLATE AU 100 TL electrolyte demonstrates exceptional throwing power that results in good coverage of recesses, holes and hollows of parts of complex geometry.
NB SEMIPLATE AU 100 TL deposits have main applications in MEMS processing.

NB SEMIPLATE AU 100 TL has the following characteristics:
- very stable bath, sulfite based
- very uniform thickness
- shiny surface, grain refiner free of arsenite
- low temperature plating
NB SEMIPLATE AU 100 TL is a ready-to-use product. It is not necessary to add other materials for the initially start of the application. Over time, it may be necessary depending on the electrolyte and application to add additives (see data sheet).
In comparison with other gold plating processes, the NB SEMIPLATE AU 100 TL electrolyte demonstrates exceptional throwing power that results in good coverage of recesses, holes and hollows of parts of complex geometry.
Deposits from the NB SEMIPLATE AU 100 TL process also exhibit the unique ability to build brightness with increasing thickness. Specific gravity measurements of the deposit consistently show values of 19.1 which indicate freedom of codeposited polymers generally found in deposits from other systems of similar purity. NB SEMIPLATE AU 100 TL deposits have main applications in MEMS processing.
