Services
PK Systems provides electronics design and embedded software development for product teams building deployable hardware. We take on defined work packages (new design, bring-up, debugging, redesign, or manufacturing handover) and deliver outputs your engineers can maintain.
Typical deliverables include schematics/PCB layout, firmware and drivers, bring-up notes, test notes/results against agreed acceptance criteria, and a handover pack (source code, build instructions, and design files). If a project is stuck, we focus on root-cause diagnosis and clear, actionable fixes.
Our area of expertiseElectronics + embedded software for real products — from early prototypes through production support. We define scope clearly, document engineering decisions, and deliver buildable, testable outputs so your team can ship and maintain the work.
Electronics Circuit Design
Schematic capture, component selection, and design reviews for new and existing products. We design for testability, manufacturability, and reliability — not just “it works on the bench”.
Outputs typically include schematics, BOM, key calculations/notes, and support through prototype bring-up and early fault-finding.
Analogue and digital electronics
Design of mixed-signal electronics: sensor front-ends, ADC/DAC interfaces, digital logic, and microcontroller peripherals.
We help you make the right trade-offs on noise, resolution, timing, and cost, with documented assumptions and test points for bring-up.
Design for EMC compliance
Design reviews and layout guidance focused on EMC risk reduction: grounding/return paths, filtering, shielding strategy, and cable/interface robustness.
We can propose practical mitigations early (component and layout changes) to reduce late-stage rework and test failures.
PCB Routing
PCB placement and routing for signal integrity, power integrity, and manufacturability across single- and multi-layer boards.
Outputs include routed PCB files, fabrication notes, and review notes highlighting critical nets and constraints.
PCB Prototyping
Prototype build support: releasing manufacturing packs, handling queries, and supporting assembly/test bring-up.
We can work with your chosen manufacturer, or recommend what information to request (stack-up, impedance, assembly constraints).
PCB Design for manufacturing
DFM-focused PCB review and release packs: stack-up, drill/annular ring, assembly clearances, test access, and documentation.
Goal: reduce surprises at build time and make the first prototype run as close to production as possible.
