Electronics design, from schematic to certified production hardware.
A1SI picks up hardware programs at any stage and drives them to a production hand-off: block diagram, schematic, PCB layout, prototype bring-up, EMC pre-compliance, and DFM-cleaned files for the contract manufacturer. We work at the bench every day — Altium and LTspice on the desktop, a Saleae and a Tektronix scope at the elbow, a test fixture wired to the panel that's about to enter production. The engineering posture comes from 30+ years of shipping production-floor controllers (Ford FN-145 seat testers, the DVP2 digital multi-printer, the Spartan ActiveRide suspension controller); every board we ship is designed to be testable, repairable, and respinnable in vendor-neutral file formats.
Every hardware program touches the same six disciplines in some combination. A1SI runs all of them in-house, with the people who own the schematic also running the bring-up and the EMC pre-compliance scan — no hand-offs across walls, no "another team owns that signal."
Analog & mixed-signal design
Op-amp and instrumentation-amplifier stages, precision references, ADC / DAC interfaces, sensor front-ends. Ground-loop discipline, current-return-path planning, anti-aliasing filters specified against the converter datasheet. PSpice and LTspice models on every non-trivial loop before layout.
Digital & high-speed
MCU and SoC integration, FPGA bring-up, DDR3 / DDR4 memory, USB 2.0 / 3.0, Gigabit Ethernet, PCIe Gen 1 / 2, MIPI CSI/DSI. Controlled-impedance stack-ups, length-matched buses, eye-diagram analysis where the margin is real.
PCB layout
2-layer prototypes through 16+ layer controlled-impedance production boards. Mixed analog / RF / digital partitioning, plane-stitching strategy, design-for-manufacture and design-for-test passes, vendor-neutral IPC-2581 / ODB++ / Gerber + IPC-356 netlist hand-off.
EMC / EMI compliance
Pre-compliance scans in the lab and at the chamber, conducted and radiated emissions, ESD / EFT / surge resilience. Design-stage filter and layout choices that get a board through FCC Part 15 (Class B / Class A), CE EN 55032 / EN 55035, and the IEC 61000-4 transient suite — not after-the-fact ferrite-bead remediation.
Signal & power integrity
Stack-up planning, decoupling network design, PDN target-impedance budgets, TDR-validated transmission lines, VNA-measured impedance on the controlled-Z layers. Power rails sequenced and characterized at every load step before firmware bring-up starts.
Thermal management
IR thermography on every bring-up, junction-to-ambient budgets against the BoM's package thermals, heatsink and airflow design where the margin is tight. ANSYS Icepak or Siemens FloEFD conjugate heat-transfer modelling for forced-air and free-convection enclosures.
How we engage
Five steps from concept to production hand-off.
We organize every hardware program around the same five-step flow so you always know where the work is, what the next gate is, and what the deliverable looks like at each stage.
1
Concept & requirements
Block diagram, BoM cost target, regulatory scope, environmental envelope, test-plan outline. The artifact: a written requirements doc the schematic will be reviewed against.
2
Schematic design
Component selection against second-source and lifecycle constraints, SPICE simulation on the non-trivial loops, design reviews. The artifact: a schematic + BoM that meets every requirement in the doc above.
3
PCB layout
Stack-up + impedance budgets, placement + routing, signal- and power-integrity checks, DFM / DFT pass with the chosen CM. The artifact: IPC-2581 / ODB++ / Gerber + drill + IPC-356 netlist, ready for fabrication.
4
Prototype bring-up
First-article assembly review, power-up under current limit, rail sequencing, firmware bring-up, EMC pre-compliance scan, thermal IR pass. The artifact: a bring-up report against the test plan, with every checkbox green or with a written disposition.
5
Production hand-off
DFM-cleaned files, panelization, ICT / AOI / flying-probe fixture design, supplier qualification, first-production-lot review, ongoing yield support. The artifact: a production package the CM can build to with no engineering-side questions left open.
The bench
Industry-standard tools, vendor-neutral output.
Every project uses the right tool for the job, but the deliverable is always portable: ODB++ / IPC-2581 / Gerber + a written test plan, not a proprietary database the next engineer can't open. If your team prefers KiCad, we ship in KiCad. If your CM expects Altium, we ship in Altium. The output is what's portable; the choice of input tool is what's pragmatic.
KiCadOpen-source alternative for cost-constrained programs, academic collaborations, and projects where the customer's long-term toolchain choice is unsettled.
LTspice · PSpiceAnalog and power-stage simulation on every non-trivial loop. Models from Linear / Analog Devices, TI, Vishay, Wolfspeed for transient and AC sweeps before the schematic goes to layout.
Keysight ADS · HFSSRF capture and 3D electromagnetic solver for impedance-controlled lines, RF front-ends, and antenna placement. EM co-simulation against the layout, not against a guess.
ANSYS Icepak · FloEFDConjugate heat-transfer simulation for forced-air and free-convection enclosures. Junction-to-ambient budgets validated against the BoM's package thermals before the heatsink BoM is ordered.
Saleae · Tektronix · RigolBench instrumentation for bring-up: 16-channel logic analyzer, 4-channel scope with FFT and bus decode, VNA, TDR, spectrum analyzer, EMC pre-compliance receiver, IR thermal camera.
What we deliver
A production-ready package, not a handoff headache.
Every program closes with the same artifact list — files in vendor-neutral formats, a written test plan with results, and a DFM-clean production package the CM can build to without an engineering escalation.
Board complexity
2-layer prototypes → 16-layer controlled-impedance production
Built the same way we build the production-floor controllers we ship.
Reliability by design, not by remediation
Every board is engineered against a written test plan before the first prototype is ordered, and every test on that plan is run against the first article. If a test fails, the disposition is written into the report — accept, rework, redesign — and the design loop closes against the disposition. We do not ship designs that fail their own qualification suite.
Production-floor pedigree
A1SI's predecessor companies have been shipping production-floor hardware controllers since 1992 — the Ford FN-145 seat testers, the DVP2 digital multi-printer, the Spartan ActiveRide suspension controller, the GM ATEC EPROM programmer. Lessons from the line — operator-readable diagnostics, savable serial logs, openly-documented interfaces — shape every board we touch.
Open, vendor-neutral hand-off
ODB++ / IPC-2581 / Gerber + IPC-356 netlist + IPC-A-610 acceptance criteria + a written bring-up report. Your CM gets every artifact in a vendor-neutral format; your next engineer gets a design they can open in the toolchain of their choosing. No lock-in to a proprietary file format, no NDA-only IP, no "trust us, it works."
A1SI picks up programs at every stage — concept, schematic, layout, bring-up, EMC pre-compliance, production hand-off, second source, end-of-life redesign. Send the block diagram, the regulatory target, or the bring-up report you're stuck on; we'll come back with what we'd do next and what the engagement would look like.
