What tools are needed to solder circuit boards?
Soldering iron, solder, flux
Should solder be reheated on a circuit board?
Yes, once or twice using flux but only with prototype boards.
A common cause of failure of electronic circuit boards is due to?
dry solder joints
Can an iron nail replace a wire in a circuit?
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
What precautions should be observed when soldering printed circuit boards?
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.
What does a solder do?
Removes solder from electronic components so that they can be removed from the circuit board
What tools are needed to solder circuit boards?
Soldering iron, solder, flux
Should solder be reheated on a circuit board?
Yes, once or twice using flux but only with prototype boards.
How do you connect a chip into a circuit board?
i think you solder it on :)
How do you change a fuse mini refrigerator?
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
What is a solder reel?
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.
What is chip soldering?
when solder IC chips on printed circuit cards
1997 dodge neon speedometer not working?
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.
Is flux in solder?
In some solder it is. But even if it is in the solder you should still use flux.
What are the uses of De-solder Guns?
De-soldering gun is used for removing molten solder, defective components, altering, and salvaging high value components in a circuit for possible re-use.
How do you fix the odometer display it only works intermittently and the Tachometer seems to be connected to the same circuit in a Chrysler Sebring?
there is probably a broken solder joint on the instrument cluster circuit board. if you look at the circuit card itself there will be 2 resistors that look burned. by them there is a solder joint that connects the front and back of the board. check to see what side is not making connection and add solder to it. it takes a couple hours to do, and the solder job doesnt need to be perfect.
What are the two alloys used to construct electronic circuit board solder?
Tin and Lead solder is the most common. The international trend is changing as the EU nations are moving toward non lead based solder.
