在电子制作,尤其是作为产品的线路板制成品中,为防止印制板受潮影响电路性能,以及运输中的强烈震动导致元器件引脚折断、脱落等故障,通常在印制板焊装后要经过清洗、干燥、喷漆或涂胶等工艺措施,以保证产品的可靠性和性能的长期稳定性。元器件焊装后印制板上残留有松香、焊油等助焊剂,必须及时清洗干净以免焊剂中的酸性物质腐蚀印制板和元件引脚,甚至造成焊点间漏电而影响电路性能。业余制作中最常用的清洗剂为工业酒精(纯度95％)和
In electronic production, especially as a product of circuit board products, in order to prevent damp printed circuit board circuit performance, as well as strong vibrations in transportation lead to broken components pins, off and other failures, usually in the PCB welding After going through cleaning, drying, painting or coating and other process measures to ensure product reliability and long-term stability of performance. Components after the soldering PCB remain rosin, welding oil and other flux, must be promptly cleaned to avoid flux of acid corrosion of PCB and component pins, and even cause leakage between the solder joints and affect the circuit performance. The most commonly used cleaning agent in amateur production is industrial alcohol (purity 95%) and
