The solder joints should be convex and shiny.
Soldering iron, solder, flux
Yes, once or twice using flux but only with prototype boards.
dry solder joints
An iron nail can replace a short length of wire in a circuit if the points of contact of the nail to the rest of the circuit have no rust or corrosion and good connection can be made. Using solder to join the nail to the circuit can help make a good connection. However, if this is for a scientifically controlled experiment fine as long as its very low voltage. If you are considering high voltage . DO NOT ATTEMPT IT. Its extremely dangerous
Never use a acid core solder only resin core should be used and keep the temperature of the soldering iron as low as possible 250 deg C max soldering should be done in a well ventilated space.
Soldering iron, solder, flux
Removes solder from electronic components so that they can be removed from the circuit board
Yes, once or twice using flux but only with prototype boards.
i think you solder it on :)
You need to take the back of the mini fridge off and then locate the circuit board and use a solder gun and unsolder the two points for the fuse
A reel of solder used for joining electrical circuits together on circuit boards. Solder is made of a mixture of tin and lead and sometimes has has flux (a form of acid) in the core of the solder to ensure a clean surface for the solder to flow into.
when solder IC chips on printed circuit cards
Could be the speed sensor or another common problem with neons is broken solder points on the instrument cluster circuit board. To test it, see if your cruise control can keep you at speed. If so, it's the instrument cluster. If not could be the speed sensor. If you don't have cruise, then you may have to inspect the cluster for broken solder points.
De-soldering gun is used for removing molten solder, defective components, altering, and salvaging high value components in a circuit for possible re-use.
Tin and Lead solder is the most common. The international trend is changing as the EU nations are moving toward non lead based solder.
dry solder joints
Always and only solder.
