By creating
the design in this way, I'm shouldering 100% of the
liability on the design. While a company I contract might do
essentially the same thing, I feel more comfortable from a liability
standpoint.
Morally (maybe not legally) I feel happier doing a solid design with
adequate protective devies (fuses, thermal fuses, proper earthing, etc)
than getiing somebody else to meet my spec and to miss out what I regard
as imporntat because it wasn't in the spec. Perhaps it's about time thsse 'masses'
learnt to solder :-) -tony
Let's relate one of my customers: Jim. He lives in
mid-state IA, USA,
and he knows how to solder.
But, his hands tremble significantly, to the point that soldering is
fast becoming impossible. He's OK soldering up LV stuff, as the risk is
small, and the reward is great.
He would not appreciate being asked to solder up his own PSU.
He also is hesitant about asking a friend or outsider to solder one up
for him. He doesn't want to impose, and he doesn't want to embarrass
himself. He makes fun of his trembling, but I know that it bothers him
incredibly.
He prefers, from a quality of life aspect, and to avoid the
embarrassment, to simply pay for a complete item.
