Precision Fixture for RF Shield Assembly

Product Specifications

Technical details and manufacturing context for Precision Fixture

Definition

A precision fixture is a critical component of the RF Shield Assembly Station that provides exact positioning, alignment, and secure clamping of RF shielding components during assembly operations. It ensures repeatable accuracy for consistent shield placement, proper contact between shield elements, and reliable electrical connections while preventing damage to delicate shielding materials. The fixture is typically constructed from aluminum alloy 6061-T6 with hard anodized surface treatment, or stainless steel, offering a surface hardness of HRC 45–50. It operates within a temperature range of 0–60°C and is rated IP54 for dust and splash resistance. Key parameters include a clamping force adjustable from 500 to 2000 N via a pressure regulator, positioning accuracy of ±0.02 mm with repeatability of ±0.01 mm (per ISO 230-2), operating pressure of 0.4–0.6 MPa (below 0.4 MPa clamping force is insufficient), and a clamping stroke of 10–25 mm adjustable per component size. The fixture weighs between 5 and 12 kg depending on size and material. Electrical resistance exceeds 100 MΩ at 500 V DC (per IEC 60243-1). These specifications serve as reference ranges; actual values must be confirmed with the manufacturer for specific models and applications. The fixture is designed for use in computer, electronic, and optical product manufacturing, specifically for RF shield assembly processes.

Working Principle

The fixture uses precisely machined locating surfaces and adjustable clamping mechanisms to hold RF shield components in their exact required positions. It incorporates alignment pins, datum surfaces, and controlled clamping force to maintain component orientation during assembly operations such as soldering, welding, or mechanical fastening of RF shields to electronic assemblies. The clamping force is adjustable via a pressure regulator, and the operating pressure range is 0.4–0.6 MPa. The fixture's positioning accuracy and repeatability are verified per ISO 230-2, ensuring consistent performance across cycles. The design prevents damage to delicate shielding materials while ensuring proper contact and reliable electrical connections.

Frequently Asked Questions

What materials are used for the precision fixture?

The fixture is typically made from aluminum alloy 6061-T6 with hard anodized surface treatment, or stainless steel. The material grade and surface hardness (HRC 45–50) are reference values; confirm with the manufacturer for specific models.

What is the clamping force range?

The clamping force is adjustable from 500 to 2000 N via a pressure regulator. The operating pressure range is 0.4–0.6 MPa; below 0.4 MPa, clamping force is insufficient. Verify actual values for your application.

What is the positioning accuracy and repeatability?

Positioning accuracy is ±0.02 mm with repeatability of ±0.01 mm, tested per ISO 230-2. These are reference values; confirm with the manufacturer for the specific model.

What is the operating temperature range?

The fixture operates in a temperature range of 0–60°C. Seals may degrade above 60°C. Always verify with the manufacturer for your environment.
