Functional Testing

Ltec Test & Automation offers commercial functional test systems for a broad range of manufacturing test applications, including Medical Device and Automotive applications. Designed for production testing, our solutions are optimised for throughput, reliability, repeatability, and cost.

Functional test systems feature a scalable architecture and are designed to meet a wide range of requirements, such as:
➢ High speed analog & digital functional test – VXI, PXI, and GPIB based instrumentation
➢ High speed digital test pattern generation, acquisition, and analysis
➢ LabWindows CVI™, Labview™, Visual C/C++,.NET, C#, Teststand etc.
➢ Boundary Scan (JTAG IEEE1149.1) test integration
➢ On-board Flash and other non-volatile device programming
➢ In-system programming (ISP) of PLD, CPLD, etc.
➢ Full turnkey fixture design and integration service

With extensive experience in functional test equipment, and a broad range of software/hardware options, we will supply cost-effective production-ready test solutions to meet your test challenges. Proposals developed by our functional test engineering team include a detailed description of system requirements, test instrumentation, estimated test cycle times (as applicable), footprint, and other key specifications.
Our solutions support a full range of test applications that include in-line and end-of-line board and system level test.

More About this Service

Using the PXI hardware platform and LabVIEW software, Lasertec focus on creating a complete set of comprehensive automatic function testing to test audio, video, and various signals such as voltage, current, and digital.

Lasertec prioritise the following test functions:

• Multiple high-speed bidirectional I/O that monitors the state of the fixture and realises communication protocols such as I²C to implement the sequential control of most chips on the PCBs
• Multiple analog input and output channels that can generate waveform signals as the simulated inputs for the PCBs
• Multichannel programmable switch matrix for on-off control
• RS232, RS485 serial port card to realize serial communication
• Programmable multimeter for voltage and current measurement
• Oscillograph for frequency measurement and waveform acquisition
• Video generation, acquisition, and analysis
• Audio acquisition and analysis
• Programmable power module
• Unified programming environment

Using traditional instruments to achieve this level of functionality would require prohibitively high costs and resources. Implementing the NI solution with PXI and LabVIEW helped Lasertec to achieve our goals and cut costs by half which in turn is passed on to our customers.
