Abstract
The invention discloses a tinning solution brightener. The tinning solution brightener comprises, by weight, 150-250g/L of polyoxyethylene aliphatic alcohol ether, 1-5g/L of urea, 10-20g/L of sulfonic acid, 200-300g/L of ethanol, 400-500g/L of methanol and the rest of the tinning solution brightener is water. The tinning solution brightener is reasonable in formula, good in stability of tinning solution and high in glossiness of produced products.
Description
Technical field
The invention belongs to the electroplating chemical technical field, be specifically related to a kind of tin plating solution brightening agent.
Background technology
The universal demand that has strengthened lead-in wire electron-like element of electronic product, for weldability and the electroconductibility that improves electronic component, leads of electronic component need to carry out zinc-plated processing, but the product surface smooth finish that present plating solution is produced is poor, affects quality product and use properties.
Summary of the invention
The object of the present invention is to provide a kind of formula reasonable, plating solution performance is stable, the tin plating solution brightening agent that the product surface smooth finish of producing is good.
Technical solution of the present invention is:
A kind of tin plating solution brightening agent is characterized in that, namely formula is by weight: polyoxyethylene aliphatic alcohol ether 150-250g/L, urea 1-5g/L, dithiocarbamic acid 10-20g/L, ethanol 200-300 g/L, methyl alcohol 400-500 g/L, excess water.
The present invention fills a prescription rationally, and tin plating solution is stablized, and the product glossiness of producing is high.
Embodiment:
A kind of tin plating solution brightening agent, namely formula is by weight: polyoxyethylene aliphatic alcohol ether 200g/L, urea 2g/L, dithiocarbamic acid 10g/L, ethanol 200g/L, methyl alcohol 400g/L, excess water.
