Removing enameled wire from Litz wires is a common but troublesome problem during electronics manufacturing and repair. Enameled wire is an insulating material used to prevent short circuits between wires. However, when soldering or connecting Litz wires, this enamelling must be removed to ensure good electrical contact. Traditional removal methods are often time-consuming and laborious, and may even damage small litz wires.

The process of removing enameled wire needs to be both precise and careful to avoid physical damage to the Litz wire. While there are various paint removal tools and chemicals on the market, they are often not suitable for the small and fragile Litz wire. In addition, improper paint removal methods can result in incomplete removal or leave residue, which can affect the quality and reliability of electrical connections.

The following methods can remove the enameled wire from the Litz wire:

1.Choose the right tools

Heat Gun: A heat gun is a highly effective tool for quickly softening and removing paint encrustation, especially on thicker litz wire. But you need to pay attention to controlling the temperature to avoid burning the copper wire.
Chemical paint strippers: Specialized chemical paint strippers can dissolve paint packages without damaging copper wires. However, care must be taken when using it to avoid harm to the environment and the user’s health.

2.Precise operation steps

Preparation: Work in a well-ventilated environment and wear appropriate protective equipment.
Application Tools: If using a heat gun, maintain proper distance and temperature; if using chemicals, apply evenly with a small brush and follow product instructions.
Cleaning treatment: After removing the paint package, clean the Litz wire thoroughly with alcohol or other cleaners to ensure that there is no residue.

3.Things to note and common misunderstandings

Temperature control: When using a heat gun, excessive temperature may burn the Litz wire.
Chemical Safety: When using chemical paint strippers, ensure adequate safety measures to avoid inhalation or skin contact.
Patience and Delicacy: Removing enamel is a process that requires patience and meticulousness. Impatience may result in damage to the wire or incomplete removal.
