Wire crimping and Soldering. Which one is better?

Wire crimping” has pros in that it is easy to install, the electricity can flow smoothly, and it can be used with various equipments. But the cons are that it costs money due to the tools used in the process. On the other hand, “Soldering” uses Flux to make electrical contact, which is cheaper than wire crimping. But the wire and contact point have less flexibility. If you use soldering in equipment that causes vibration, there is a risk of broken wires.

How many Wires can crimp together?

It is not recommended for pair multiple wires in one crimp terminal when wire crimping. Because crimp terminals are designed to work with a specific size of wire, when multiple wires are combined in one crimp, the holding force is reduced, resulting in heat at the terminal.

Should you twist the wire before crimping?

If stranded wire is used in wire crimping, The twisted method of copper wire before wire crimping will increase the surface density. The chance that a wire terminal will be loose or fall out after crimping is going to be reduced. and the risk of an electrical accident is also decreased.

Can you use plier for wire crimping?

It is not recommended to use pliers to crimp the wire except “Wire Crimper”. because there is a chance that the wire terminal will be loose or damaged, which is called “Bad Contact”. And when the equipment is running, the heat at the terminal is going to increase more than usual because electricity cannot flow smoothly. It will cause the ark to and melted wires. Therefore, should study how to use the crimping pliers properly to prevent the danger that may occur.

FAQ Crimp Terminals

Question: Wire crimping and Soldering. Which one is better?: Answer: Wire crimping” has pros in that it is easy to install, the electricity can flow smoothly, and it can be used with various equipments. But the cons are that it costs money due to the tools used in the process. On the other hand, “Soldering” uses Flux to make electrical contact, which is cheaper than wire crimping. But the wire and contact point have less flexibility. If you use soldering in equipment that causes vibration, there is a risk of broken wires.
Question: How many Wires can crimp together?: Answer: It is not recommended for pair multiple wires in one crimp terminal when wire crimping. Because crimp terminals are designed to work with a specific size of wire, when multiple wires are combined in one crimp, the holding force is reduced, resulting in heat at the terminal.
Question: Should you twist the wire before crimping?: Answer: If stranded wire is used in wire crimping, The twisted method of copper wire before wire crimping will increase the surface density. The chance that a wire terminal will be loose or fall out after crimping is going to be reduced. and the risk of an electrical accident is also decreased.
Question: Can you use plier for wire crimping?: Answer: It is not recommended to use pliers to crimp the wire except “Wire Crimper”. because there is a chance that the wire terminal will be loose or damaged, which is called “Bad Contact”. And when the equipment is running, the heat at the terminal is going to increase more than usual because electricity cannot flow smoothly. It will cause the ark to and melted wires. Therefore, should study how to use the crimping pliers properly to prevent the danger that may occur.
