From oscilloscopes and spectrum analysers to automated test equipment and precision calibration instruments — ultra-low-noise, controlled-impedance PCBs engineered for measurement accuracy.
Test and measurement products define the performance floor for every other industry. The PCB must not be the limiting factor.
High-frequency RF boards on Rogers laminates for 77 GHz forward collision, lane departure and autonomous driving sensor fusion.
Heavy copper BMS boards for cell monitoring, thermal management and charge control in hybrid and full-electric vehicles.
High-temperature multilayer boards for ECU and TCU operating near the engine bay from -40°C to +150°C.
HDI multilayer boards for in-vehicle displays, connectivity, navigation and digital cluster platforms.
IPC Class 3 boards for ABS, ESP, airbag control and active suspension — zero tolerance for in-field failure.
Standard multilayer PCBs for door locks, window controls, lighting automation and central body electronics.
Metal-core and aluminium PCBs for matrix LED headlights and adaptive lighting systems.
Robust multilayer PCBs for climate control, seat adjustment and ambient environment management.
A T&M instrument's PCB is not a carrier — it is part of the measurement system. Every parasitic, every impedance discontinuity and every material choice affects instrument accuracy.
While automotive accepts ±5% impedance tolerance, oscilloscope front-end boards require ±3% or tighter to maintain flat frequency response across bandwidth. This demands tighter trace width control (±0.3 mil), lower Dk variance laminates and VNA post-fab verification — not just TDR.
±3% impedance · ±0.3 mil trace · Dk < 0.001 variance · VNA verifyA 1 nV/√Hz noise floor instrument cannot afford PCB layer stackup choices that introduce ground loop noise, power supply coupling or parasitic resonance. Ground plane continuity, split plane avoidance and via-back-drilling are essential design elements, not optional refinements.
1 nV/√Hz · split plane avoidance · back-drill · ground planeSpectrum analysers and VNAs operate into the millimetre-wave range. At 100+ GHz, standard microstrip on FR4 has unacceptable loss. Rogers 3003, Isola I-Tera MT40 and ceramic-filled PTFE are required, with cavity milling for waveguide and connector integration.

High-Tg low-Dk laminates (Isola I-Tera, Rogers 4350B) for controlled impedance acquisition boards. Tighter trace tolerance of ±0.3 mil achieved with our advanced photolithography process. VNA verification available on all acquisition-critical boards.
Rogers 3003C, Taconic RF-35 and PTFE for instruments operating above 40 GHz. Cavity-milled waveguide transitions, coin-backed ground planes and electrolytic hard gold on all RF probe contacts. TDR and VNA verification on every board.
For calibration standards and precision passive component measurement, minimising PCB parasitics is as important as trace impedance. Our process delivers via capacitance below 0.1 pF and trace inductance matched to femtohenry accuracy on metrology boards.
Every parameter below is verified against IATF 16949 and IPC-A-600 Class 3 requirements. Full test reports and material traceability ship with every order.

T&M customers need quantified process capability, not qualitative claims. We provide TDR reports, trace width measurement data and laminate Dk certification with every precision order — so you know your instrument's PCB performance before assembly.
Real automotive PCB challenges — and how we solved them.
16-layer precision board on Isola I-Tera MT40 for a 20 GHz oscilloscope acquisition front-end. ±3% impedance on all probe input lines, back-drilled via stubs, TDR and VNA verified before shipment.
Flat frequency response within ±0.2 dB to 20 GHz confirmed on VNA. Crosstalk between adjacent input channels 6 dB better than previous design. Instrument shipped 6 weeks ahead of programme schedule.
20-layer Rogers 3003C board for a 67 GHz spectrum analyser. Cavity-milled waveguide transitions, electrolytic hard gold on all waveguide interfaces, full VNA characterisation on every board.
Insertion loss at 67 GHz within 0.3 dB of simulation. All boards shipped with individual VNA data files. First production batch passed instrument calibration at 100% — no RF touch-ups required.
24-layer ATE probe interface board for a wafer-level semiconductor tester. 256 simultaneous test channels, 3 GHz bandwidth per channel, ±2% impedance tolerance, nickel-free gold finish.
All 256 channels met impedance specification at first build. Crosstalk between adjacent channels 4 dB below customer specification. Board service life exceeded 1 million probe touches before first replacement.
Automotive procurement teams need more than a PCB factory — they need a certified partner with documented processes, fast engineering response and the depth to solve problems before the production line.
Our advanced photolithography and etch process delivers ±0.3 mil trace width control, enabling ±3% impedance on precision boards. Every board ships with a TDR report. No estimates, no sampling — measured data.
For mmWave and precision boards, we go beyond TDR — VNA insertion loss measurement is available on every board. Your instrument's RF performance is confirmed at PCB level before assembly begins.
We hold Rogers 3003C, Isola I-Tera MT40 and PTFE in stock. No lead time for material procurement — your mmWave board goes straight into production.
