TEST PROBES | 26 June, 2001

I am looking for info on symptoms : what happens to test probes when height is not set right and are overstocked ? I am finding black coating or coloration on sliding part of the probe. Is it normal ?

Thanks in advance for your help.

Ya gota stop messing with that NC stuff, bud. The residues will kill you. Look at http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&&Message_ID=4649&_#Message4649

What are you trying to get at when you say "what happens to test probes when height is not set right and are overstocked?"

Is a black coating or coloration on sliding part of the probe normal ? I wouldn�t call anything normal when it turns gold plated test probes black. Should you expect to see it if you�re running NC flux? Ubetcha!!! Is it an insulator? Ubetcha!!! Does it affect the continuity between the probe and the outer-contacts on the test probe? Ubetcha!!! Wudyagunnado? Tell me where you buy probes and I�ll buy stock in their company.
