Photoresist Boards

Photoresist boards are a fundamental component in the field of electronics, particularly in the manufacturing of printed circuit boards (PCBs). They are typically made of a material like fibreglass or composite epoxy and are coated with a layer of photoresist. This photoresist is a light-sensitive material that changes its properties when exposed to specific wavelengths of light.

Core Features and Benefits of Photoresist Boards

• The use of photoresist boards allows for exact and intricate circuit patterns to be created.
• These boards streamline the PCB manufacturing process, as they enable quick and accurate transfer of circuit designs onto the board.
• Suitable for both high-volume production and small-scale, bespoke PCB creation.

Composition and Characteristics

The core of a photoresist board is usually a non-conductive substrate, like fibreglass. The photoresist layer applied to this substrate is designed to be sensitive to ultraviolet (UV) light. When exposed to UV light, the photoresist goes through a chemical change, which allows for the selective removal of the exposed or unexposed areas, depending on whether it is a positive or negative photoresist.

Typical Applications of Photoresist Boards

The use of photoresist boards in electronics manufacturing signifies a blend of precision, efficiency, and versatility, making them an indispensable tool in the modern electronic industry, such as:

• Electronics Manufacturing: They are predominantly used in creating PCBs for various electronic devices, from simple gadgets to complex computer systems.
• Prototyping: Ideal for prototyping and experimenting with new circuit designs due to their flexibility and precision.
• Educational Purposes: Often utilised in educational settings to teach students about PCB design and manufacturing processes.
