이러한 관점에서 Pb Solder는 Pb의 매장량이 높고, 결착성이 좋으며 가장 좋은 특성으로는 낮은 융점 때문에 Pb Solder의 사용이 널리 퍼져 있었다. 사실 접합부에 Pb를 사용하는 것은 전도도가 좋기 때문은 아니다. Pb의 전도도는 Cu의 7%밖에 되지 않는다. 그러나 Pb를 사용하게 된 이유는 역시 대량 생산제품의
properties. However these properties are dependent on humidity, in other words, with higher humidity more water is absorbed. The water, which acts as a plasticiser, will then reduce its tensile strength, but increase its elongation and tear strength. PVA is fully degradable and is a quick dissolver.

Polyvinyl acetate, PVA, PVAc, poly(ethenyl ethanoate), is a rubbery synthetic polymer wi
