求助 ROHS 问题(damoguyan发的)

ICP光谱

  • 电路板中的电容,电阻,电感,芯片是ROHS要豁免的电子部件吗?(豁免Pb)
    另外,一般的电路板上的焊锡是属于高温焊锡吗

    在RoHS最新指令中,對於玻璃介質的部分可以豁免鉛的檢查,所以對電阻、電感包括芯片部分進行錫腳的檢查!另外一般來說,RoHS對於被檢測元件不作整體豁免!
    9. Lead in electronic ceramic parts (e.g. piezoelectronic devices).
    Ceramic materials are used in a variety of electronic devices including capacitors,
    insulators, piezoelectrics, magnets and integrated circuit packages. Some of
    these ceramic materials contain lead, for example lead zirconate titanate and
    lead magnesium niobate. The specific chemical composition and manufacturing
    process of these materials determine their electrical parameters, such as
    dielectric constant and the dissipation, that is essential for the functioning of the
    component in which they are used. Hence, lead used in the ceramic parts of
    electronic components in electrical and electronic equipment is exempt from
    these Regulations.

    PCB表面焊锡应不属高温焊锡,我司目前就用的锡银铜合金上锡属无铅锡,上锡温度也只有245度
