[求助]如何在大概0.1pa的真空室用BNC將導(dǎo)線引出來(lái)？ [復(fù)制鏈接]

本人看的文獻(xiàn)上說(shuō)用的是焊接，但會(huì)有發(fā)裂（hairline crack），這樣會(huì)破壞真空，需要用檢漏裝置探測(cè)發(fā)裂（原文：The valve and BNC connectors were welded onto the flanges 4 QWHGh"  
and we think it likely that a hairline crack is responsible for the bad performance of the vacuum.）。請(qǐng)問(wèn)專業(yè)人士如何在不破壞真空的情況下將導(dǎo)線引出。 PHx No)   m\(a{x  
本人是新手，希望能詳細(xì)解答。謝謝!
