¿Qué es el Principio de funcionamiento de un Láser Depaneling?
El principio de funcionamiento de láser depaneling implica el uso de un láser de alta energía del haz de precisión de corte a través de la conexión de las pestañas o los canales de enrutamiento de un PCB (Placa de Circuito Impreso) en el panel, la separación de tableros individuales sin contacto mecánico. Una fuente de láser, tales como el CO2 o el láser UV, genera un haz enfocado de que se dirige hacia el PCB material a través de un sistema óptico.
When the laser interacts with the material, its energy is absorbed, causing localized heating and vaporization (ablation) along the programmed cutting path. This process is controlled by software that guides the laser head with high precision, enabling the creation of complex shapes and fine details to be cut cleanly. Since laser depaneling is a non-contact method, it eliminates mechanical stress, reduces the risk of damage to sensitive components, and produces minimal debris, making it ideal for high-density and delicate PCB designs.
¿Qué Tipos de Láseres que se Utilizan en Láser Depaneling?
Los Láseres de CO2:
- Best for cutting non-metal materials, such as FR-4 (a common PCB material).
- Fast and cost-effective, but can’t cut metals well.
UV Láser:
- Great for high-precision cutting, especially for flexible PCBs or materials with copper.
- Very accurate with minimal heat damage, but slower and more expensive.
El Láser Verde:
- Used for specific materials like flexible circuits.
- Offers good precision but is less common and more costly.
Los Láseres De Fibra:
- Used for cutting metal-based PCBs.
- Efficient for metals but not suitable for non-metal materials.
Los Láseres De Femtosegundo:
- Ultra-high precision with almost no heat damage.
- Ideal for delicate materials, but very expensive and slow.
Picosegundo Láseres:
- Similar to femtosecond lasers but slightly less precise.
- Still high-cost and used for advanced applications.
Excimer Láser:
- Used for very precise cutting of special materials.
- High resolution but expensive and complex to maintain.
