What is the best type of lubricant for Omnibus backplanes?
It can be a struggle to insert and remove PDP-8/e boards into the Omnibus.
There is a risk of damage to the brittle bakelite connector housings on the
Omnibus PCB.
Traditional contact sprays should work but have two problems:
1) they remain wet and over time will attract and retain dust
2) the solvent and lubricant *may* weaken or attack the bakelite
There are some PTFE (Teflon) based lubricant sprays which create a dry
film. Would this type of spray work?
Any suggestions on what I could use that reduces the strain on the Omnibus
and the PCBs during insertion/removal without creating new problems?
Thanks and best regards
