Dual Stage Methods

At Forwessun, we offer highly reliable dual stage, also known as bi-level or multilevel, ICT and FCT methods. Our dual-stage fixture methods are designed to offer versatile and cost-effective solutions for a wide range of printed circuit board (PCB) testing needs, from low node-count boards to highly complex, high node-count PCBs.

Our Vacuum Actuation & Pneumatic Control dual-stage methods are the ideal solution for testing low node count PCBs. These methods feature a two-stage operation:

• 1st Stage: Vacuum-controlled actuation that provides gentle but secure contact with the unit under test (UUT).
• 2nd Stage: Pneumatically controlled mechanisms ensure a smooth and consistent dual-stage testing process.

These methods are known for their low-cost maintenance and high reliability, making them a popular choice for testing PCBs in a variety of industries.

For more complex PCBs with high node counts (over 2000 nodes), Forwessun offers non-vacuum, fully pneumatic bi-level fixtures. These fixtures are designed to accommodate complex network boards, RF boards, and other PCBs that require advanced testing capabilities.

Features:

• High Node Count Capability: Ideal for testing boards with over 2000 nodes.
• Advanced Features: Supports UUT cooling units and mating connector insertion mechanisms.
• Complete Coverage: Provides extensive coverage for complex testing requirements, ensuring high-quality results.

Forwessun offers advanced dual stage/bi-level ICT and FCT fixtures tailored for various testing needs. Our vacuum-actuated solutions are ideal for low node count PCBs, providing cost-effective and maintenance-friendly options. For more complex and high node count PCBs, our fully pneumatic, non-vacuum bi-level fixtures ensure comprehensive coverage and reliable results.
