Forwessun Test Systems Ltd Forwessun is a global company with over 30 years experience in providing test fixtures, test software and test systems service and support. We have an excellent reputation for providing first class software and fixture solutions and build quality in from the start. We have the most advanced manufacturing facility in the world and can provide you with the highest quality solutions at short time leads. Forwessun provides total test support Functional Test Fixtures Forwessun provide all types of functional test fixtures and complete solutions. Fixtures are custom designed to connect with all leading manufacturers of functional modules or can be standalone with electronics integrated inside the fixture housing Integrated Electronics
Standalone Test Fixture Below is an example of a stand alone test fixture with operator control buttons and top probing of the board under test. Small Node Count Fixtures. Floating plate design protects the probes and ensures the contact is truly 90 O vertical and is guaranteed to hit within 9 thou of the centre of each test pad. Forwessun provides a G10 mask with every fixture which can be used to verify test fixture accuracy.
Automatic Connector Insertion Pneumatically controlled connector insertion includes force monitoring and safety backoff. Mechanical CAM Systems. If no factory air supply is available or the test location is required to be easily moved the fixture can be manually connected to the board under test using a CAM mechanism to engage the test probes.
External Instruments Rather than integrate custom test electronics inside the fixture, the wiring can be terminated at connectors for external benchtop instruments. This allows multiple fixtures to use the same test equipment. Build to Print Forwessun have the flexibility to build custom fixtures to a customers design in very short leadtimes and in any volume.
Flexguard. Forwessun Flexguard FEA software is used during test fixture design to identify and report all the forces and automatically position the push downs to protect the board under test and to ensure board flatness. Advantages of Flexguard Full PCB Finite Element Analysis Supports Design For Test (DFT) Fully automatic fixture design Minimises design time Eliminates unnecessary pushers Reduces build time Fully interactive 2D/3D visualisation Absolute deflection and Microstrain analysis FlexGuard operates directly on board CAD allowing us to detect potential problems even before board design is finalised and long before fixture manufacture starts. FlexGuard enhances our DFT services by allowing us to highlight potential board and component breaking stresses at the earliest stages.
Advanced Fixture Manufacture - Quality Through Automation. We build quality into each stage of manufacture this starts with using the best materials. Drilling is performed on our Pluritec drill system. The four head system can handle multiple jobs simultaneously for heavy workloads. Probe & bearing positions are drilled on the Pluritec drill center with milling completed on one of 4 separate ROC routing stations. Receptacles and probes are automatically inserted on one of our Insertion systems. This is achieved by a pneumatically driven, hydraulically damped 'touchless' process which guarantees probe tip accuracy.
Wiring is done on one of our semi automated wiring systems, each with real time verification for error free wiring. As the wires are added to the fixture a flying probe confirms that each wire has been connected to the correct position before allowing the wiring to continue. When wiring is complete, the next stage of verification is performed on one of two flying probe wiring verification systems that confirm that there are no shorts or opens in the test fixture and that each probe connects to the correct interface position.
Once test fixture manufacture is completed and the fixture has been quality inspected, a test program engineer performance checks the fixture on the target test system. The engineer will run any available software against the target board. The programmer does not work for production and takes responsibility for the overall quality of the fixture. What this means for you is that we can supply you error free, high quality, high accuracy test fixtures, quickly and at the right price. Efficient manufacture gives you the customer improved lead time and reduced costs. Forwessun uses staged inspection and verification. All Forwessun test fixtures carry a life time guarantee. Onsite Support. We have experienced Forwessun engineers around the world and can provide you and your manufactures local onsite support through out Europe and Asia.
