Or maybe a situation where the item in question was working fine when you put it away and then the next time you go to use it, you get nothing? Sound familiar? It’s possible you have dry solder joints (don’t worry they don’t hurt…) Dry solder joints are a very common problem with all electronics. Especially any that lead a hard life; for example, devices that create lots of heat, or ones that vibrate or even stuff you plug things into (and out off) repeatedly. All this heat, movement and action weakens the delicate solder joints holding all the gubbins onto the printed circuit board (PCB’s). Especially any joints that were not too good in the first place, most of our stuff is mass-produced by the lowest bidder don’t forget! A dry solder joint is where the solder connecting the component pin or leg to the copper track on the circuit boards becomes damaged. Bad contact with the copper track of course means a poor connection (intermittent problems) or no contact at all (device stops working altogether). Damage is often either… Heat related where the pins/legs and the solder surrounding them expand and contract at different rates in use eventually causing cracking and erosion of the solder. Fatigue related where the connection between the component pin/leg and the copper track cracks due to repeated movement or flexing. Dry joints are caused by several things… Intermittent heating/cooling where expansion and contraction stresses connections, (power tools for example). Frequent and repeated moving of switches and other controls. Often the one used most creates very localised stress, (the max setting on the vacuum cleaner or cooker hood for example). Repeated pushing and pulling on plugs or cables physically flexes the joints between the component pins/legs and the circuit board (audio equipment for example). Devices that get very hot in use will eventually suffer from one too many heating/cooling cycles. Expansion and contraction stresses connections, (panel heaters for example). Machines that vibrate a lot because they use a big, fast motor. Vibration stresses the joints between the component pins/legs and the circuit board, (washing machines for example). Devices that move around a lot. Electronics don’t like being thrown around too much or being knocked about as they are a bit delicate really, (laptops for example).
