不怕大家笑话,我是电子元件技术行业的外行.但现在自己从事销售电子元器件,有些技术方面的问题真的很令人头痛.前段时间向客户出售了TDA6060XS INF 这款IC,我也是从别的供应商那拿的货,供应商说是原装的,但客户测试后说不能用,供应商那又不能退货,但客户硬把货退回来了.所以请哪个大侠指点一下,在下真的万分感激.
我发过去的TDA A5 6060 XS,客户说他从别家买的是原装的是TDA B5 6060 XS.
并测试结果:
GROUND -------------to------------ Vcc 必须显示为1 MOHM,也就是说R=1MOHM.他还说我们的IC是西门子的,R=1000 ohmand.
不太会翻译,我把原文放在上面:
GROUND -------------to------------ Vcc must show the 1 MOHM. to meaning of must show the R =1MOHM,but when your IC with SIEMENS mark test in factory's LAB ,show the R=1000 ohmand this subject show the defect of this IC ,and show the short circuit and immidiately when 5 V enter to it, the IC have not R and could't bear.and again this case show the defect of this IC
surely you don't know about to this subject and this is error that sent us different serial no.
请各位大侠帮忙,我怎么才能知道我的IC不是原装的,是客户弄错了还是供应商骗了我?谢谢!!!! |
