SPEA Test Cell Concept

• All the components are designed and manufactured directly by SPEA for the integrated working: This guarantees best technical performance, cost optimization, one-shot factory integration.

• A single equipment combines the elements or the handling, contacting and complete testing of MEMS devices, including the physical stimulus for functional test, and the tri-temp thermal conditioning.

• The cost of test results greately reduced, thanks to the high throughput, the lower investment, the short application development time and the rapid accomodation of different applications

 

High-Throughput P&P Handling

• Input from Tray, Bulk (bowl feeder), Carrier
• Output on tray, Tape/Reel, Bulk, Carrier
• Automatic binning
• Zero-shock handling
• Up to 18,000 UPH
• Quick system reconfiguration
• Fast head & pickup replacement
• Conversion kits for standard and customized packages
• 2x2 to 40x40 mm package size, with or without leads & BGA 

Complete Testing with Stimulus

• 99% Parallel test efficiency
• Test function libraries for MEMS devices
• High multi-site MEMS contacting unit: up to 32 devices in parallel
• Trapezoidal velocity profiles with programmable velocity for accelerometers
• Sinusoidal velocity, constant velocity, combined sinusoidal profiles with programmable amplitude and frequency for gyroscopes
• Pressure stimulus 30 ÷ 450 kPa
• Tri-temp test: -40 to +125 °C

Full Final Test Concept

SPEA test cells perform the complete parametric and functional test on the fully packaged devices, at the end of the production process.
After the test, the products can be directly shipped to the customer, without needing any further working or re-test.

Reel Sort Unit

SPEA MEMS Test Cells and pick&place test handlers, equipped with the RSU Reel Sort Unit, can perform the tray-to-reel handling of the tested devices. This configuration offers highthroughput, full automation, high reliability, with the possibility to choose if placing the devices in tray or in reel, according to the single application, on the same equipment.

The handling is based on a fast pick and place unit that picks the tested PASS components from the testing area, and place them on one or two automatic tape transport units.

High reliabiltiy is guaranteed by the optical inspection, performed when the components are placed into the tape pockets, in order to verify their correct position and orientation.
