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 Tom Hunter
