Good morning Technet, One of our products was returned to us due to a bad contact between the leads of a PLCC and the socket in which it is placed. Somebody here got the idea that the contact failure might be a result of fretting corrosion, and that using an anti-fretting lubricant may be the solution for it. At a previous employer we used such a lubricant for some connectors, but I have never heard of lubricating the contacts of a PLCC socket. Any opinions on this ? And what else can cause contacting problems in a PLCC socket after some time ?
