Does soldering wire add resistance?
The copper-on-copper connection is generally superior to solder considering that most solders have more resistance than copper. In practice, the difference in resistance between either methods (properly done) is beyond the accuracy range of average multimeters.
Is it OK to solder electrical wires?
The best solder to use for tinning stranded copper wire is electrical-grade rosin-core solder. This is an acid-free solder that contains a flux in the core of the solder. Never use solder that contains acid, which can damage the wire or its insulation. Acid-core solder is intended for use in plumbing applications.
Why is solder good for circuit boards?
2.1 Best Solder For Circuit Board—The Lead-based Solder The lead alloy solder has been an industry standard for a long time. It contains a mixture of tin and lead in a percentage of 60/40. The tin in this alloy mixture lowers the melting temperature because the circuit boards are sensitive to high temperatures.
What type of solder is best for circuit boards?
rosin core solder
For electronics soldering, the most commonly used type is lead-free rosin core solder. This type of solder is usually made up of a Tin/Copper alloy. You can also use leaded 60/40 (60% tin, 40% lead) rosin core solder but it’s becoming less popular due to health concerns.

How does a PCB trace increase current capacity?
To increase the current capability of a trace you can remove the solder mask which exposes the copper underneath. Then additional solder can be added onto the trace, which will grow its thickness and reduce resistance.
Can a copper wire be soldered to a PCB?
Soldering a copper wire will bring big gains as a standard PCB is 35µm. In comparison with a 1mm and a 2mm copper wire: Thanks for contributing an answer to Electrical Engineering Stack Exchange!
What does a copper trace on a PCB do?
A PCB trace or PCB track is a copper conductor on the PCB that conducts signals on the surface of the PCB. It is the flat, narrow portion of the copper foil that is left behind after etching. The electricity that flows through the copper traces generates a significant amount of heat.
What kind of current does a PCB carry?
Digital, RF, and power circuitry mostly process or transfer low power signals. These applications have copper weights from 1-2oz and carry current from mA to 1A or 2A. Some applications such as motor controls require currents up to 50A, this will require higher copper weights on the PCB and larger trace widths.
