We all know that sulfuric acid hydrochloric acid based tin plating brighteners have been widely used due to their high current efficiency, fast deposition speed, low electroplating cost, and easy treatment of wastewater. Recently, a customer has reported that the tin plating layer on tin plated engineering workpieces is prone to problems such as poor stability of the plating solution, poor solderability and oxidation resistance of the coating, which cannot meet the functional requirements of electronic components. So, how can we choose a high-performance acid tin plating brightener?
Guangdong Bigley Technology Co., Ltd. is a high-tech enterprise that integrates research and development, production, sales, and service. Bigley has been engaged in professional research and development, production, and sales of tin plating brighteners for 16 years, with rich production experience and a complete service system, and has gained recognition and trust from domestic and foreign customers. Bigley's sulfuric acid hydrochloric acid based tin plating brightener Sn-807 is specially developed for the bright acid tin plating process, suitable for the production of hanging or rolling plating of semiconductors and electronic components. It has the following four characteristics:
1. The bath has good chemical stability. The plating solution prepared with ordinary tin plating brightener will turn yellow and appear cloudy after being left for about a week; Even if the plating solution of this Sn-807 is left for more than a month, there will be no obvious discoloration or turbidity. In this way, during the production process, the plating solution can remain clear for a long time, effectively reducing the treatment frequency of the plating solution, and thus extending the service life of the plating solution.
2. Wide operating range, Sn-807 can obtain a uniform and bright tin plating layer that is not easily oxidized or discolored within the operating range of temperature 15-30 ℃ and current density 1-4A/dm2. The plating solution management and maintenance are simple.
3. Excellent welding performance. The tin coating on the workpiece is between 8-10 μ When the thickness is m, high-temperature soldering test is conducted, and there will be no phenomenon of tin accumulation in the tin coating.
4. Low consumption. This sulfuric acid hydrochloric acid based tin plating brightener Sn-807 is produced using imported raw materials with high concentration. There are many decomposition products during the production process, and the consumption is very small. It is only Sn-807A: 200-300 milliliters/kiloampere hour, and Sn-807B: 100-200 milliliters/kiloampere hour.
So, Bigley's sulfuric acid hydrochloric acid based tin plating brightener Sn-807, which has good stability, wide operating range, good welding performance, and low consumption, is worth choosing.
