MAR AC-77 Accelerator is a non-fluoride product. It enhances catalyst activity on glass and dielectric materials. It provides a void free and reliable electroless copper deposit.
The AC-77 Accelerator processes approximately 500 surface square feet per USG. Solution should be discarded when either throughput reaches 500 ssf/USG or when the copper metal reaches 2,000 ppm (2g/l).
|Palladium||10 ml/litre of ENAU PDS will increase Pd content by 10 mg/l|
|Normality||10 ml/litre of Sulphuric acid s.g. 1.84 will increase the Normality content by 0.36 N|
|MAR AC-77||8 - 12%||10%|
|Temperature||20 - 32°C||Ambient|
***Analysis to be done daily***
|Tanks:||Polypropylene, HD Polyethylene, PVC|
