- **Screen Printing**: This technique allows for precise application of the glass glaze in specific patterns or designs.
2. **Drying and Curing**: After the glaze is applied, the resistors undergo a drying and curing process to solidify the glass coating. This step is essential for achieving the desired mechanical and electrical properties.
D. Sintering Process
1. **Temperature Control**: The sintering process involves heating the coated resistors to a specific temperature, allowing the glass to fuse and bond with the substrate. Precise temperature control is critical to avoid damaging the resistor.
2. **Time Management**: The duration of the sintering process is also carefully managed to ensure optimal performance. Too short a time may result in incomplete bonding, while too long can lead to degradation of the materials.
E. Electrical Termination
1. **Attachment of Leads**: Once the resistors are sintered, electrical leads are attached to facilitate connection in electronic circuits. This step is crucial for ensuring reliable electrical performance.
2. **Soldering Techniques**: Various soldering techniques are employed to secure the leads, ensuring a strong and conductive connection.
V. Quality Control Measures
Quality control is paramount in the manufacturing of glass glaze resistors to ensure they meet the required specifications.
