In the rapidly advancing electronics manufacturing sector of the UAE, precision and reliability are paramount. Waterjet cutting technology has emerged as a key solution, enabling manufacturers to work with a broad range of materials without causing thermal distortion. This cold-cutting process has found widespread use across consumer and industrial electronics, thanks to its precision, material versatility, and cost-efficiency.

This case study explores how waterjet cutting is used in the electronics industry, the types of materials it supports, and the advantages it offers for electronics production in the UAE.

How Does the Electronics Industry Use Waterjet Cutting?

Waterjet cutting technology plays a crucial role in electronics manufacturing, especially in applications that require precision and non-thermal processing. In the UAE, where the demand for advanced electronics in sectors such as automotive, telecommunications, and medical devices is growing, manufacturers increasingly rely on CNC waterjet systems to meet strict quality standards.

Key uses include:

• Casing and frame cutting for smartphones, laptops, televisions, and audio equipment.

• Semiconductor fabrication, including water dicing and wafer edge grinding.

• Custom prototyping and R&D, where high-precision internal cuts are required.

• Precision component manufacturing for sensors, circuit boards, and internal device parts.

What Materials Does Waterjet Cut in the Electronics Sector?

Aluminum

Aluminum is widely used in electronics due to its strength and lightweight properties. It is used in frames, casings, heat sinks, and internal components. Waterjet cutters provide clean, burr-free edges ideal for precision assembly.

Copper

Used extensively for electrical conductivity, copper plates and sheets are vital in printed circuit boards (PCBs), antennas, and thermal systems. Waterjet cutting avoids oxidation and maintains dimensional integrity.

Lithium

Lithium is a critical material in battery production. Due to its delicate nature and the small quantities involved, only ultra-precise methods like waterjet cutting—with tolerances as tight as ±0.001″—can be used.

Titanium

For rugged and lightweight electronics, titanium offers an ideal strength-to-weight ratio. Waterjet cutting handles titanium effortlessly without tool wear or thermal damage.

Silver

Common in touchpads, microwaves, TV displays, and PCB traces, silver requires fine and consistent cutting. Waterjet can achieve the delicate tolerances required in these applications.

Gold

Gold is used for bonding wires, connectors, and circuit coatings. Waterjet cutting offers a clean and controlled process for slicing thin gold sheets with minimal waste.

Nickel

Nickel-based components in batteries and electrodes are frequently processed with waterjet cutters due to their intricate shapes and thermal sensitivity.

Plastics and Polymers

Waterjet is perfect for cutting high-strength plastic components used in device enclosures, keypads, and insulators. Since the process generates no heat, plastics retain their structural integrity.
