Packaging

Upon passing the inspection, the fuse chokes are carefully packaged. The packaging is designed to protect the products from damage during transit and handling, ensuring they reach the customer in perfect condition.

Unloading and Inspection

After the soldering process, the fuse chokes are unloaded from the machine. Each product undergoes a thorough inspection process to ensure it meets all quality standards. This may include checks for dimensions, solder quality, and overall assembly. It is crucial that the inspection process is rigorous, as any defects in the solder joint or assembly could affect the functionality and safety of the fuse choke.

Winding process

The manufacturing begins with a winding machine, which plays a crucial role in forming the initial structure of the fuse choke. The machine pulls wire from a spool, stripping it at predefined locations. This step is essential for preparing the wire for subsequent soldering and assembly. The stripped areas of the wire are fluxed and tinned in line, a critical process for ensuring good solderability and electrical connectivity. The wire is then wound into two springs with precise angles on the legs, as specified by the design requirements. This precision is key to the functionality of the fuse choke.

Automated Soldering Process

The assembled core and springs are then fed into an automatic machine. This machine performs several critical functions:

• Automatic 100% test of the force of the fuse legs. This makes sure the fuse function will be ensured
• Clamping both central legs against each other: This ensures proper alignment and contact for the soldering process.
• Fluxing the central legs of the springs: This prepares them for the soldering process.
• Dip tinning: The fuse area is dipped into a tin bath in order to solder the fuse legs.
• Applying solder paste: Solder paste is precisely applied to the areas where the legs will be joined.

• Induction heating of the solder paste: The machine uses induction heating to melt the solder paste, thus soldering the central legs together.

This process needs to be carefully controlled to ensure a strong and reliable solder joint.

Core Insertion

Once the springs are wound, they are manually inserted onto a core. This manual insertion allows for careful handling and precise alignment, which is crucial for the performance of the fuse choke.
