Acid Etching Machine for PCB Manufacturing

Acid Etching Machine plays a vital role in the PCB (Printed Circuit Board) manufacturing process. It removes unwanted copper from the PCB surface through a controlled acid etching process, creating precise copper traces. This process is essential for producing electronic circuits, ensuring the accuracy and performance of the final PCB.

Our acid etching machines feature advanced technologies, including adjustable spraying systems, temperature and pressure controls, and high-durability materials. These innovations help us meet the demanding requirements of the PCB manufacturing industry.

Key Features

– Efficient Etching System
The machine uses a double spray system to apply the etching solution evenly and consistently across the PCB surface. The spraying system works together with an oscillation function, ensuring uniform etching throughout the entire board.

– Advanced Control System
The etching machine features an **automatic control system** that allows for precise adjustment of key parameters such as working speed, etching pressure, and bath temperature. This control system ensures that the etching process is optimized for various types of PCB materials and thicknesses, offering flexibility and precision.

– Acid High-Temperature Resistance
Designed to handle the harsh environment of acid etching, the machine uses PP and Titanium material, which can withstand high temperatures up to 90°C . This durability ensures long-lasting performance, even in high-temperature operations.

– Versatility
This acid etching machine is suitable for etching a wide range of PCB types, including single-layer, multi-layer, and high-frequency PCBs. It can handle board thicknesses ranging from 0.2mm to 3.2mm , making it versatile for different production needs.

Applications of Acid Etching Machines

1. PCB (Printed Circuit Board) Manufacturing

In PCB production, acid etching removes excess copper from the surface of the board to form circuit traces. This is essential for creating electrical pathways in electronic devices such as smartphones, computers, and automotive electronics.

Key Benefit : Ensures high precision and fine details for reliable electrical connections.

2. FPC (Flexible Printed Circuit) Manufacturing

Acid etching removes copper from flexible materials like polyimide or PET film in FPCs. Manufacturers use these flexible circuits in applications such as wearables, mobile phones, and medical devices.

– Key Benefit : Allows for flexible, lightweight circuits that can be bent and shaped without losing functionality.

3. LED Manufacturing

Acid etching is employed in LED production to create fine metal traces on LED chips or metal substrates. This is crucial for forming electrical pathways in LED drivers, displays, and lighting systems.

– Key Benefit : Enables high-resolution patterns for energy-efficient and compact LED systems.

4. Metal Etching

In metal etching, acid etching machines are used to create detailed designs on metals like copper, brass, and stainless steel. This process is used for circuit boards, decorative items, and industrial components.

– Key Benefit: Provides precise and intricate etching for both functional and decorative purposes.

The acid etching machine is an indispensable tool in the PCB manufacturing process. With its ability to deliver precise, efficient, and high-quality etching, it ensures the production of reliable and high-performance PCBs used in countless electronic applications.
