Solutions for Circuit Board QA
Quality assurance in PCB manufacturing demands fast, repeatable measurements — from incoming component inspection to final functional test. UNI-T instruments provide the precision, automation capability, and durability needed for production environments, with connectivity options for integrating into automated test workflows.
Oscilloscopes — Signal Integrity & Protocol Validation
Functional testing of assembled PCBs requires both analog signal verification and digital protocol validation. The MSO3034HD (350MHz, 12-bit) captures clean waveforms with protocol decoding for SPI, I2C, UART, CAN, and LIN — ideal for verifying communication buses on assembled boards. Its deep memory (500Mpts) supports long captures for intermittent fault detection.
For higher-volume test stations where cost matters, the UPO2204HD (200MHz, 12-bit, 4-channel) delivers excellent measurement quality at a lower price point. For basic go/no-go testing, the UPO1104 (100MHz, 4-channel) covers most production test needs.
Spectrum Analyzers — EMI Pre-Compliance Testing
Catching EMI issues before formal compliance testing saves weeks and thousands of dollars. The UTS1032T with the UTS1000-EMI software option provides automated EMI pre-compliance testing against CISPR, FCC, and MIL-STD limits — with pass/fail mask testing and report generation. Pair it with the UTS-EMI01 near-field probe kit for pinpointing emission sources on the PCB.
For production-floor RF characterization, the UTS3036B (3.6GHz) provides the resolution and dynamic range for component-level testing.
Waveform Generators — Stimulus for Functional Testing
Generating test signals for board-level validation requires stable, low-distortion output. The UTG2062X (60MHz) provides SCPI-programmable dual-channel output for automated test sequences. For more demanding stimulus requirements, the UTG2122X (120MHz) adds higher frequency and more arbitrary waveform memory.
Bench DMMs & Power Supplies
The UT8806E (6.5-digit) provides the accuracy and speed (10,000 readings/second) needed for production measurement — with LAN, USB, and RS-232 connectivity for automated data collection. For powering boards under test, the UDP3305C (3-channel programmable linear supply) provides clean, stable power with remote sense capability.
