Description
рата окиси аммони , фторида аммони и монопероксигидрата карбамида определ ютс координатами точек поверхности треугольника Гиббса-Розебома (сш чертеж).Ammonium oxide, ammonium fluoride and carbamide monoperoxyhydrate are determined by the coordinates of the surface points of the Gibbs-Roseboma triangle (USA drawing).
На чертеже цта поверхность ограничена кривой ABCDEK и заштрихована.In the drawing of the cool surface is limited curve ABCDEK and shaded.
|При указанных оптимальных значени х содержани гидрата окиси аммони оптимальные значени содержани в растворе будут дл монопероксигидрата карбамида от 50 до 300 г/л и дл фторида аммони от 2 до 18 г/л.At the indicated optimal levels of ammonium hydroxide content, the optimum concentrations in solution for carbamide monoperoxyhydrate are from 50 to 300 g / l and for ammonium fluoride from 2 to 18 g / l.
Травление предлагаемым раствором производитьс при температурах от 18 до 25°С и нормальном давлении.The etching with the proposed solution is carried out at temperatures from 18 to 25 ° C and normal pressure.
Вместо монопероксигидрата мочевины могут использоватьс другие пероксигидраты карбамида и его производных: дипероксигидрат карбамида , тетрапероксигидрат карбамида, пероксигидраты биурета с мольными отношени ми перекись водорода: биурет 0,2 и 0,4 соответственно .Instead of urea monoperoxyhydrate, other carbamide peroxyhydrates and its derivatives can be used: carbamide diperoxyhydrate, carbamide tetperoxyhydrate, biuret peroxyhydrate with hydrogen peroxide molar ratios: biuret 0.2 and 0.4, respectively.
Травильный раствор готовитс последовательным растворением в воде аммиака, фторида аммони и монопероксигидрата мочевины . Растворение ведетс при обычных температуре и давлении.The etching solution is prepared by serially dissolving ammonia, ammonium fluoride, and urea monoperoxyhydrate in water. Dissolution is carried out at ordinary temperature and pressure.
Результативность работы травильного раствора видна из нижеследующего примера.The effectiveness of the pickling solution can be seen from the following example.
Одни и те же печатные платы со схемным металлом из меди, но с разными резисторами (из сплава ПОС, сплава олово - никель, серебро , свинец, олово) травились в травильных растворах различного состава при температурах от 18 до 25°С. Полученные при этом результаты приведены в таблице.The same printed circuit boards with a circuit metal from copper, but with different resistors (from an alloy of PIC, an alloy of tin - nickel, silver, lead, tin) were etched in etching solutions of different composition at temperatures from 18 to 25 ° С. The results obtained here are shown in the table.
