Lubricant for PCB's
Lubricant for PCB's
(OP)
Hi,
We have a Printed circuit board which sits on an aluminium plate. The contact surface have some tracks but no components. So I am just wondering if there are any lubricants which will and can stop rubbing against these tracks? I thought of epoxy potting compound but could be a problem during repairs. Please let me know if there are any alternatives?
Thanks in advance!

If you need some kind of thin insulator then look at conformal coatings or maybe tapes etc.
Kapton may be an obvious material to consider http://en.wikipedia.org/wiki/Kapton.
If you need it super slidey then UHMWPE or PTFE tape or similar might be worth a look.

Well I would never design a PCB w/exposed traces that sit on aluminum.. That's just asking for a short if any of those traces are at a different potential.

Even if you use insulation that doesn't break down, it's not hard to conjecture a situation where moisture wicked into the capillary gaps between insulation and traces will cause problems.
Move the damn traces off the damn faying surface.
... and yell at the designer who put them there.

Also, there are some compounds made for ensuring thermal conduction between components and heat sinks. I recall the replacement electronic ignition module for my old El Camino came with a tube of such stuff.

insulating sheets, thermal gap pads, standoff hardware, etc... will all solve the problem as posted but I'd suspect there is an underlying reason the board was put there in the first place.
Any pcb designer/engineer should know that a soldermask should never be relied upon for insulation.
