打印機和(he)X線解析設備中(zhong)的電(dian)(dian)(dian)(dian)源為高(gao)電(dian)(dian)(dian)(dian)壓(ya)，所(suo)以(yi)驅動電(dian)(dian)(dian)(dian)路所(suo)使用(yong)的電(dian)(dian)(dian)(dian)子部件要具備很(hen)高(gao)的最高(gao)使用(yong)電(dian)(dian)(dian)(dian)壓(ya)。此外，電(dian)(dian)(dian)(dian)動汽車和(he)混動汽車的電(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)路中(zhong)，電(dian)(dian)(dian)(dian)壓(ya)也很(hen)高(gao)，所(suo)以(yi)電(dian)(dian)(dian)(dian)阻的最高(gao)使用(yong)電(dian)(dian)(dian)(dian)壓(ya)要很(hen)高(gao)。

在(zai)過去，電子電路基板使用有(you)(you)鉛(qian)(qian)(qian)焊(han)錫，也就是鉛(qian)(qian)(qian)與(yu)錫的合金，但鉛(qian)(qian)(qian)對人體有(you)(you)害，而且危(wei)害自然環(huan)境(jing)(jing)，因此(ci)近年來，焊(han)錫的無鉛(qian)(qian)(qian)化(hua)日益普及。歐(ou)洲還(huan)通過RoHS指(zhi)令，自2006年7月開始禁(jin)用鉛(qian)(qian)(qian)等6類有(you)(you)害物質(zhi)，日本、中(zhong)國等非歐(ou)洲國家(jia)也加(jia)強了限制，為適應上述趨勢，旺銓合金電阻公司正在(zai)通過電阻器端子無鉛(qian)(qian)(qian)化(hua)等各項措施，努力削減(jian)環(huan)境(jing)(jing)負荷(he)物質(zhi)。
