摘要
针对同轴电缆垂直镀锡工艺中锡液从导入管缝隙中泄漏的问题,通过分析缝隙中锡液的受力状态,计算出保证垂直镀锡过程中不发生锡液泄漏的同轴电缆与导入孔之间的最大间隙。计算结果表明,在锡液深度为100mm,温度为260℃条件下,在0.05～0.15m/s的镀锡速度范围内,为了保证锡液不泄漏,同轴电缆与导入孔之间的最大间隙为0.188mm。计算结果与试验情况吻合良好,实际的测试结果表明,采用最大约0.2mm间隙的导入孔,既可以保证锡液不泄漏,又可保证电缆不会被卡住,具有最佳的镀锡效果。
Aiming at the problem of tin fluid being leaking from the crevice of ingress pipe in vertical tin-plating process,through analyzing the force state of tin fluid in the crevice,the maximum gap size between coaxial cable and ingress orifice which assures no tin leakage is calculated out.The results indicate that when the depth of the tin fluid is 100 mm,the temperature of the tin fluid is 260 ℃ and the tin-plating speed is 0.05～0.15 m/s,the maximum gap size between coaxial cable and ingress orifice which assures no tin leakage is 0.188 mm.The calculated result is in accordance with the experimental result well.The practical test results indicate that if the gap size of the crevice is 0.2 mm,no tin leakage will occur and coaxial cable will not get stuck,and the best results of tin-plating will be got.
