Thanks, -do you agree that in our case, restricting the MCPCB copper traces to more than 2mm from the edge of the MCPCB (as discussed in post #3) would be completely pointless?

Thanks, indeed , Germany is the only country in the world that has “got a grip” when it comes to safety standards. –Perhaps also the USA to an extent. In my experience, the Germans know the meaning of the word “teamwork”. In the UK engineering industry, we do not understand this word.
The Germans understand that to share ones knowledge of stuff like electrical safety standards, with other German companies, (even German competitor companies) results in a better situation for all electrical co’s, and all benefit from the increased economic prowess that results from it. In UK , we do not know what it means to share knowledge with a fellow UK company. In UK, the goal is to destroy other UK companies, in an aim to be the main player in the market.
In our small company, we cannot afford to buy the safety standards, and do not know where to find which exact standard tells about this.

Page 4 of the doc in the top post speaks of EN60598, but we cant remember its exact words from when we previously read it , and cant afford to now buy it

..appears to state that, for an MCPCB, if the LED voltage is non-isolated and/or >120V, then a bare bit of copper must exist on the MCPCB for the purpose of connecting a probe to it so that a high voltage insulation test can be done….between the MCPCB trace and the earth ground.
Is this correct?

I think in our case, the law is that insulated screws (made of plastic or bakolite) must be used to screw the MCPCB to the Earthed heatsink. Also, I believe that a separate “rubber” insulating pad must be used between the MCPCB and the earthed heatsink. Do you agree?
We cannot phone up a fellow UK competitor company and request advice on this, because they will tell us to “go drop dead”. –in the UK, it is not like in Germany where competitor companies correctly realise the benefits of actually helping your competitors.
