一、開槽參數(shù) (tank set up parameters)
硫酸亞錫(stannous sulfate):10~15g/l
硫酸 (sulfuric acid):15~20 g/l DBR-601:20~25 g/l
二、控制參數(shù) (coolling parameters)
硫酸亞錫(stannous sulfate):10~15g/l
游離酸(free acid): 15~18g/l PH (value): 0.8~1.2
溫度(Temperature): 18~22℃ 時(shí)間(Time): 0.5~10min
三、維護(hù)和管理 (maintenance and cool)
1.每天檢測槽液濃度并按分析結(jié)果及時(shí)調(diào)整,硫酸亞錫和DBR-601按1:2比例添加。每處理100m2約消耗DBR-601:0.4~0.6Kg。槽液的總酸度控制在30~40g/l。
Detection of the bath conceation one time a day, according to the analysis results to adjust; it added stannous sulfate and DBR-601 can be 1:1.5~2 ,the DBR-601 of consumption is 0.4~0.6Kg for each 100m2 treatment aluminum. Total acidity cool in 30 ~ 40g / l.
2.添加硫酸亞錫時(shí)須同DBR-601先混合再溶解于槽液中;向槽中補(bǔ)加純水時(shí),必須在攪拌下緩慢加入,以防止局部硫酸亞錫水解,導(dǎo)致槽液發(fā)渾。
When added stannous sulfate, it should be mixed with the DBR-601 first and then dissolved in the bath , added water, you must join slowly in the stirring, to prevent partial hydrolysis of stannous sulfate, tending to bath volatility .
3.槽液對銅雜質(zhì)較敏感,清理導(dǎo)電銅座時(shí)須特別注意不得污染槽液。
Producing bath will produced more or less white precipitate for a long time , you need to filter or reverse the bath to clean sediments regularly. Affix the bath to prevent contamination when stop produce
