线路板焊接是指将印制板上的元器件按照规定的尺寸,按设计要求,按照一定的顺序和方向安装在印制板上,并使之形成完整的电路系统。线路板后焊就是指在电路板焊接完成后,为了保证电路板上元器件之间连接牢固、可靠,在PCB板上将元器件与印刷电路板焊接起来。然后,再对印制电路板进行清洗、组装和测试.线路板后焊一般是由以下几个步骤构成的:先将元器件放进对应的孔位内,加热洛铁,使锡融化,将物料焊接到印刷电路板上;再用洗板水对印刷电路板进行清洗,祛除表面油污和助焊剂等物质;接着对印刷电路板进行干燥处理,使其表面干燥,然后再进行测试和维修。常见的焊接方式分为两种,一种是人工操作,用洛铁焊锡,人工操作,连锡,假焊少,但是速度慢,常见于样品/小批量生产;另外一种就是利用机器,插好物料的pcb板过波峰焊,机器生产,速度快,适合批量加工,但是受局限,间距太小的孔位容易连锡,且机器设置不当,容易出现虚焊假焊的情况。两者优缺点差不多,所以均为加工厂所用。线路板多层板72H加(jia)急出样品?推荐深圳市骏杰鑫(xin)电子有(you)限(xian)公司!浙江(jiang)DIP线路板交期
