Description
Флюс, содержащий (в вес. %):Flux containing (in wt.%):
30 канифоли, 20 метилтетрагидрофталевого ангидрида и 50 этиленгликол , можно растворить в 50 вес. % этилового спирта.30 rosin, 20 methyltetrahydrophthalic anhydride and 50 ethylene glycol, can be dissolved in 50 wt. % ethanol.
При введении одноатомного гидрофобного €4-Си спирта флюс содержит (в вес. %):With the introduction of monatomic hydrophobic € 4-C alcohol, the flux contains (in wt.%):
10-40 канифоли, 10-40 метилтетрагидрофталевого ангидрида и 20-80 указанного спирта.10-40 rosin, 10-40 methyltetrahydrophthalic anhydride and 20-80 of the specified alcohol.
Флюс, содержащий (в вес. %):Flux containing (in wt.%):
30 канифоли, 20 метилтетрагидрофталевого ангидрида и 50 амилового спирта может быть растворен в 50 вес. % этилового спирта.30 rosin, 20 methyltetrahydrophthalic anhydride and 50 amyl alcohol can be dissolved in 50 wt. % ethanol.
Флюс после пайки удал ют этиловым или изопропиловым спиртом, спирто-бензиновой смесью (1 : 1), фреонами, азеотропными составами на основе фреонов и спиртов и другими органическими растворител ми.After soldering, the flux is removed with ethyl or isopropyl alcohol, an alcohol-gasoline mixture (1: 1), freons, azeotropic compositions based on freons and alcohols, and other organic solvents.
Предлагаемый флюс обладает гидрофобными свойствами и более активен, чем известные флюсы.The proposed flux has hydrophobic properties and is more active than the known fluxes.
Предмет изобретени Subject invention
Состав флюса на основе канифоли, растворенной в спирте, отличающийс тем, что, с целью повышени активности флюса, в его состав введен метилтетрагидрофталевьш ангидрид при следующем соотношении между компонентами (вес. %):The composition of the flux on the basis of rosin dissolved in alcohol, characterized in that, in order to increase the activity of the flux, methyl tetrahydrophthalic anhydride is introduced into its composition in the following ratio between components (wt.%)
Метилтетрагидрофталевьш ангидрид10-40 Канифоль, растворенна в спирте Остальное.Methyltetrahydrophthalic anhydride 10-40 Rosin dissolved in alcohol Else.
