Industrial sensor boards
Signal-conditioning and interface boards built for plant-floor electrical noise.
PCB Design Services
Schematic capture, multilayer PCB layout, component selection and manufacturing-ready output for embedded, industrial and IoT hardware.
Overview
What this service covers
PAK-EL LAB designs printed circuit boards for embedded, IoT, industrial and wireless products — from a first schematic revision through a fully panelised, manufacturing-ready layout. Hardware and firmware are handled by the same team, which keeps board-level and firmware-level decisions (pin mapping, interrupt lines, power sequencing) consistent instead of getting lost between vendors.
Client Problems
Problems this service solves
- A product concept exists but there's no schematic or board yet.
- An existing board has noise, thermal or reliability issues that need diagnosing and fixing.
- A design works on the bench but gets flagged during a fabricator's DFM review.
- A board needs to shrink, add a wireless radio, or move from a one-off prototype toward a small production run.
Capabilities
What we do
- Schematic capture and multilayer PCB layout
- Power-supply and power-electronics design
- Component selection and footprint verification
- Analogue, digital and mixed-signal layout
- RF-aware layout for boards carrying a wireless module
- Design-for-manufacturing (DFM) review before release
- Gerber, BOM and pick-and-place file preparation
- Review and correction of an existing schematic or PCB
Technologies
Tools & platforms
We work with industry-standard PCB tools and pick the one that best matches a project's complexity and your preferred file format. Most designs are built around ESP32, STM32 or Arduino-compatible microcontrollers as the starting reference.

Development Process
How we approach a PCB project
- 01Requirements
Confirm the board's function, interfaces, size and power constraints.
- 02Schematic
Capture the circuit and share it for review before layout starts.
- 03Layout & DFM review
Route the board and check it against the fabricator's process before release.
- 04Manufacturing handoff
Deliver Gerbers, BOM and pick-and-place files ready for your fabricator.
Deliverables
What you receive
- Schematic files
- PCB layout files
- Gerber files
- Bill of materials (BOM)
- Pick-and-place files, where the board is going to assembly
- DFM review notes
Testing & Validation
How a board gets checked before release
Every design goes through a DFM (design-for-manufacturing) review against the specific fabricator's process before Gerbers are released, catching clearance, drill and copper-pour issues while they're still a five-minute fix instead of a respin. Where prototypes come back from assembly, we support bring-up testing — checking power rails, continuity on critical nets and first-power-on behaviour — rather than treating the board as finished the moment it's fabricated.
Applications
Where this is used
IoT and wireless nodes
Compact boards carrying an ESP32/LoRa module alongside sensors and power management.
Power-electronics boards
Power-supply and motor-driver layouts designed with thermal and current-carrying capacity in mind.

How We Can Help
How PAK-EL LAB Can Help
If you need a board designed from a blank schematic, or an existing one reviewed and fixed, we can take on the full PCB design process or just the piece that's missing — schematic, layout, DFM review or manufacturing handoff. Scope, deliverables, schedule and quotation are confirmed once we understand what the board needs to do and any size, power or interface constraints. We work with clients internationally and collaborate remotely as standard practice.

FAQ
Frequently Asked Questions
Do you design the schematic from scratch, or only layout?
Both. We can take a project from a blank schematic through layout, or just handle layout if you already have a reviewed schematic.
Which PCB design tools do you use?
KiCad, EasyEDA or Altium Designer, depending on the project and your preferred file format — we'll confirm which fits before starting.
Can you review and fix an existing board instead of designing a new one?
Yes, reviewing an existing schematic or layout for a specific issue — noise, thermal, a DFM flag — is common work, not just new designs.
Do you handle the manufacturing handoff too?
Yes, Gerbers, BOM and pick-and-place files are prepared as standard deliverables, ready for your fabricator or assembly house.
