However, in the writer’s experience, the chances of receiving accidental burns from a hot iron are extremely remote anyway, as electronics hobbyists will usually park the hot iron carefully in a bench holder made for the job. A novice would have to be extremely unlucky, inept or very careless to receive any injury from an ordinary soldering iron, which is generally less dangerous to its user than, say, a cigarette lighter.
There was worse news to come with our test circuit board. It was disconcerting to see afterwards that three p.c.b. copper pads were damaged by excess heat, causing the copper track to lift away from the laminate altogether. Strangely, this was the case with both of the radial lead electrolytic capacitors: the pads lifted completely, breaking the tracks and leaving the capacitors free to wobble on the board, held in place by blobs of solder. A skilled and experienced electronics constructor could repair the damage by soldering jumper wires on the board, but the novice would face the disappointment of having ruined the board altogether.
