What is photo etching | China professional manufacturer

Product Details: Photo etching is a process that involves applying a light-sensitive photoresist material to a metal sheet. A mask with the desired pattern is positioned over the photoresist, and the metal is then exposed to light. The exposed areas are etched away using a chemical etchant, leaving the desired pattern. This process is compatible with sheet metals ranging from 0.010 mm to 2.5 mm in thickness and up to 600 mm x 1500 mm in size. It offers exceptional accuracy with standard minimum etching tolerances at ±10% of the metal thickness, down to a minimum of ±0.020 mm. The minimum standard

etched opening achievable is 0.1 mm, and for depth-etched features like microfluidic channels, it is 0.020 mm[1].

Frequently Asked Questions (FAQs)

What is photochemical etching, and how does it work?

Photochemical etching, also known as chemical milling, is a process that uses ultraviolet light to expose metal materials, triggering a chemical reaction that removes material from specific areas. This technique involves coating the metal with a photosensitive layer, exposing it to UV light through a pattern, and then immersing it in an etchant solution to remove the unwanted metal, leaving the desired shape.

What are the advantages of photochemical etching over traditional machining methods?

Photochemical etching offers several benefits, including burr-free results, fast and low-cost design iterations, and no need for expensive mold-making. It allows for rapid production, often within a few days, and can handle complex shapes and detailed features with high precision. This method is particularly useful for producing intricate metal components without the limitations of traditional machining.

What types of materials can be processed using photochemical etching?

Photochemical etching can process almost any metal, regardless of its hardness or shape. Common materials include stainless steel, aluminum, copper, and even titanium. The process can handle metal thicknesses ranging from 0.01mm to 2.5mm, making it versatile for various applications such as semiconductors, medical devices, and automotive parts.

How precise is photochemical etching, and what tolerances can be achieved?

The precision of photochemical etching depends on factors like the chemical solvent used, etching time, temperature, and the precision of the photosensitive pattern. Generally, the standard minimum etching tolerance is ±10% of the etched metal’s thickness, but it can be as low as ±0.025 millimeters. Advanced equipment and techniques can achieve even tighter tolerances.

How long does it typically take to complete a photochemical etching project?

Photochemical etching is relatively fast compared to traditional machining methods. Projects can often be completed in just a few days. For example, some manufacturers can prepare prototypes within 6 hours and deliver final products in as little as 3 days, making it an efficient option for both prototyping and high-volume production.
