锡铅镀层无氟硼酸浸亮清洗剂

A Non-fluoboric cleaner of Sn-Pb Coating

通常都是采用含有硫脲和氟硼酸的清洗剂去除锡铅合金镀层中的氧化变色层,在此推出了一种能有效去除锡铅镀层变色层,使其镀层恢复可焊性能,而又不含氟硼酸的酸性清洗剂.

Cleaners with thiourea and fluoboric acid are usually used to remove the oxidation or discoloration layer in Sn-Pb coating. This paper puts forward a cleaner which can effectively remove the discoloration layer in Sn-Pb coating without fluoboric acid, thus the weldability of the coating could be recovered.
