| titleOfInvention | A kind of engraving method of silver-copper brazing alloy |
| abstract | The present invention is a kind of engraving method of silver-copper brazing alloy, includes the following steps: (1) alkaline degreasing: soldering semi-finished product shell being put into alkaline degreasing solution and is cleaned；(2) it washes: first being rinsed with tap water, then cleaned up with deionized water；(3) pickling: the shell of washing is put into pickling solution and is cleaned；(4) it dries；High temperature drying and processing is carried out to the shell after washing with high-temperature blast drying oven；(5) etch: shell is put into etching solution；(6) after etching, shell iterative process step (2) washing, step (4) drying are taken out.Advantage: 1) no any corrosion is etched to silver-copper brazing alloy and injured, shell is brazed pattern, size, the level of coverage of solder and subsequent plating high reliablity.2) process for slowing down etching, increases the range of etching period, and 3) reduce environmental pollution；4) at low cost, it is simple and easy；5) " the silver migration " of RF power device shell, significant effect are solved the problems, such as. |
