VS Dash Green Circuit Board Repair

[krusing]

careful with the soldier heat as u can melt the contact of the c/b easily

Correct, careful of the heat,
Remember to Solder,
not to Smolder.

Worked perfect, thanks for the wire glue tip - plus Jaycar was 1/3 of the price of everywhere else, Highly recommend keeping this in the tool box anyway!

Keep in mind, it not pure metallic, like solder is.
And could cause resistance with the voltage supply to the globe, and it could heat up like a resistor and create heat on the CB.

IMHO, I would not of use that.

 

[Trevor loves holden.]

If it was pulling 50w then I would say that could happen, don't see it happing on a 5w globe, very little draw to cause any resistance.

careful with the sandpaper, you dont want to remove any copper, just clean the contact area

I did say wet and dry sand paper,
which is normally a very fine abrasive, and should be able to clean the surface up and not damage it.

Sorry, I have to agree that I disagree with your comment, and I would not use it on any of my cars.
It doesn't matter what current it draws, It is still a resistive material, and will cause heat to the back of the board, and that is how some car fires can start,
It was fairly obvious what damage that 5 watt globe had done to the donut connection on the c/board, seeing the burn marks.

Its not metallic like solder, which is tin & lead based,
and is always used on C/Boards.

It was flickering on off so yes it will have arc marks / burnt marks, here is some info.


This Graphite-Filled Conductive Wire Glue is perfect for high-temperature operating conditions metals, conductive heat-resistant adhesive like ceramic and glass materials and also for heat conductive coating.

• It's a single component, inorganic aluminosilicate material, in black.
• The conductive material is graphite and the conductive performance quality is choiceness.
• The temperature resistance is 500Ta C, under the protection of inert gas, it can be used at 1000Ta C.

WTF does any of that actually mean?
Choiceness? Please tell me that is a cut/paste error.

The temperature resistance is 500 degrees? I’m pretty sure the circuit board would be liquid at that temp.

That's what the polymers glue temperature resistance range is.
