MAR CC-18 is formulated specifically for copper foil cleaning and conditioning hole wall which is an integral step in the copper metallization process.
MAR CC-18 conditions the hole-wall which during the activation step with a palladium tin catalyst complex will seed the epoxy and glass to form a minute seed which will assist in the final formation of a tight dense copper grain structure. This cleaner conditioner contains conditioning agents, which activate glass fibers and epoxy, allowing for a reliable absorption of the catalyst.
MAR CC-18 has been formulated so it can be easily rinsed from the copper surface with cold water.
|CC-18||2 – 5%|
|DI Water||95 – 98%|
Normal operation and replenishments are accomplished by addition of 300 mls of MAR CC-18 concentrate per 1000 surface square feet processed. Bath should be replaced when 500 surface square feet are processed per gallon.
The bath should be replaced after 75 surface square meters per litre have been processed.
|MAR CC-18 Concentration||3%||2 – 5%|
