Matte Tin
Matte tin is a plating process that produces a dull surface on metal. Matte tin is corrosion-resistant and does not discolour under high temperatures.
MATTE TIN 900
SULPHURIC ACID MATTE TIN PLATING PROCESS
Physical Properties:
MATTE TIN 900 MAKE UP: Light yellow/brown Liquid
MATTE TIN 900 MAINTENANCE: Light yellow Liquid.
Description
MATTE TIN 900 is a sulphuric acid base, matte acid tin plating process suitable for rack and barrel plating.
MATTE TIN 900 baths operate over a wide concentration permitting highly economical deposition from baths with low tin metal content.
MATTE TIN 900 additives are stable so organics are minimally co-deposited with the tin.
MATTE TIN 900 process is extremely simple to control, requiring only a fraction of the lab and analysis time needed by competitive systems.
MATTE TIN 908
MATTE ACID TIN PLATING PROCESS
Physical Properties:
MATTE TIN 908 MAKE UP: Liquid
MATTE TIN 908 LEVELLER: Liquid
Description
MATTE TIN 908 is a stable leveling, matte acid tin plating process that produces a matte finish, exhibiting excellent solderability.
MATTE TIN 908 baths operate over a wide concentration permitting highly economical deposition from baths with low tin metal content.
MATTE TIN 908 baths are maintained with two additives, which are not consumed during electroplating; however, the additives are lost via drag-out. The additives must be replaced according to volume of drag-out.
MATTE TIN 908 additives are stable so organics are minimally co-deposited with the tin.
MATTE TIN 908 process is extremely simple to control, requiring only a fraction of the lab and analysis time needed by competitive systems.
