1. The spot welding of LED filament is directly controlled by a microcomputer. 2. It is convenient to reduce electromagnetic interference in LED filament welding. 3. Helps to improve the welding quality of LED filament.

- Shaped electrodes that concentrate current/heat flow - Electrodes that press against the metal pieces  - Controls/mechanisms to position electrodes accurately

In the manufacturing of multilayer ceramic capacitors (MLCCs), carrier tapes serve as critical substrates for supporting ceramic dielectrics and electrodes, where their precision and performance directly impact capacitor consistency and reliability. Traditional laser cutting or die-stamping processes are limited by machining accuracy (±20μm) and thermal stress, making them unsuitable for producing ultra-miniature 01005 (0.4×0.2mm) MLCCs. ‌Metal etching technology‌, with its unique advantages in precision microstructure fabrication, is bringing revolutionary opportunities to the MLCC carrier tape industry.
