Thanks for the career advice, but I already do. I design wheelchair controllers (for which my companty supplies to 75% of the worlds market) & also interface units for the severely disabled. I also design high power industrial controllers.Underwurlde, perhaps if you have so much experience in this field, maybe you should punt yourself around some of the leading manufacturer's and show them how to make electronic component's bulletproof.
So, yes my designs are bullet proof. They are UL, TUV, FDA, BS5750 pt14 & 510K approved. I think I know more than enough about safety critical designs, design for manufacture, and how much such products cost to design and manufacture. The products I design are produced in their hundreds of thousands per annum. There is absolutely NO reason why a 'PCB' is made down to the lowest cost should it therefore contain problems. My designs do not. That is why my company dominates the market: They are the cheapest to manufacture, are the safest and offer the best control. It's a no-brainer for the customers.
Arrogant? If so then that's probably down to the wave of rudeness and arrogance recieved in the first place.
