Using Electric Torque Screwdrivers in the Electronics Manufacturing Industry

Electric torque screwdrivers are an essential tool for any electronics technician. They help to ensure that screws are tightened to the correct torque, which helps to prevent damage to components and ensure the long-term reliability of electronic devices. SMT Supplies is a preferred distributor of Delvo Electric Torque Screwdrivers from Nitto Kohki.

These high-quality tools are used in electronic manufacturing to screw in small screws and components with precision and repeatability. They are typically used in conjunction with an electric motor controller, which controls the amount of force applied to the screw. This helps to prevent over-tightening or under-tightening, which can damage the screw or the component.

Delvo electric torque screwdrivers are also useful for tasks such as:

• Fastening circuit boards
• Installing connectors
• Securing heat sinks
• Mounting components

They can be used in a variety of electronic manufacturing environments, including clean rooms, production lines, and repair shops.

There are many benefits to using Delvo electric torque screwdrivers in your electronic manufacturing process including:

• Increased productivity by automating the screw fastening process. This can free operators to focus on other tasks, such as quality control or inspection.
• Improved quality by ensuring that screws are tightened to the correct torque. This helps to prevent damage to components and assemblies and improve the quality of finished products.
• Reduced Recoil: Sophisticated clutches and a motor braking system reduce the hand recoil at the end of the screw-tightening operation, reducing user fatigue.

• Improved safety by preventing over-tightening of screws, which can lead to component damage or failure.
• Quieter: Compare Delvo to conventional pneumatic screwdrivers and you will hear the difference. 

Brushed or Brushless Motors?

Brushed motors are the most common type of motor found in electric torque screwdrivers. They are relatively inexpensive to manufacture and can be used in a variety of applications. However, brushed motors have several drawbacks, including:

• Less efficient: Brushed motors are less efficient than brushless motors, meaning that they use more power to produce the same amount of torque. This can lead to shorter battery life and increased heat generation.
• Less durable: Brushed motors are also less durable than brushless motors. The brushes and commutators in brushed motors can wear out over time, which can lead to decreased performance and increased maintenance costs.

Brushless motors are a newer type of motor that is becoming increasingly popular in torque drivers. They offer a number of advantages over brushed motors, including:

• Brushless motors are more efficient than brushed motors since they use less power to produce the same amount of torque. This can lead to longer battery life and reduced heat generation.
• More durable: They do not have brushes or commutators, so they are less likely to wear out over time.
• More powerful: Brushless motors can produce more torque than brushed motors, making them ideal for demanding applications.

Ultimately, the best type of motor for an electric torque screwdriver depends on the specific application. For general-purpose use, a brushed motor may be sufficient. However, for demanding applications, a brushless motor is the better choice.

Using in Robotic Applications

Electric torque screwdrivers are often used in automated applications as the robot controls the amount of force applied to the screw. This helps to prevent over-tightening or under-tightening, which can damage the screw or the component. Some applications include assembly and repair of cars, appliances, electronics, and manufacturing of medical devices and PCB assemblies.

Electric torque screwdrivers offer several advantages over manual screwdrivers in robotic applications, including:

• Accuracy: Electric torque screwdrivers can be programmed to apply the exact amount of torque required, which helps to prevent damage to components.
• Repeatability: Electric torque screwdrivers can be programmed to repeat the same screw fastening process over and over again, which helps to ensure consistency.
• Speed: Electric torque screwdrivers can fasten screws much faster than manual screwdrivers, which can help to improve productivity.
