DZ-8409 Chemical Immersion Tin Process
DZ-8409 is a new type of environmental protection chemical tin precipitation process, which has the characteristics of stable performance, convenient operation and economy. DZ-8409 at 55 ℃ for 10 minutes, a pure tin layer of 0.8-1.2 microns can be obtained on the copper surface. Compared with the traditional inorganic immersion tin, the tin sinking rate is faster, the performance is more reliable, and the tin whisker is not easy to produce. The obtained tin layer has good solderability.
