PCB layout engineering
built for the board you will actually make.
Layout engineering turns a validated schematic into a board that assembles, tests and behaves. We plan the stack-up, partition the board by function, route with intent, and release complete, consistent fabrication and assembly data.
- Stack-up & partitioning
- Thermal-aware placement
- Assembly-ready data
What separates a good layoutA board that works on the bench
A board that works on the bench
and in the enclosure.
Layout decisions that look reasonable on screen can behave differently once the board sits inside a metal enclosure, next to a heat source, at the edge of its temperature range, or is assembled by a contract manufacturer working from a documentation set.
We treat layout as an engineering deliverable with its own review. Partitioning, return paths, thermal spreading, test access and assembly clarity are each checked deliberately rather than left to default settings.
Documentation is part of the layout. Stack-up drawings, notes, drill tables and assembly drawings ship with the data, so the board can be built the same way twice.
- 01Functionally partitioned
Analog, digital, power and RF blocks separated so each keeps the reference and isolation it needs.
- 02Thermally planned
Hot spots identified early, with copper spreading and via strategy chosen to move heat where it can go.
- 03Test access designed in
Test points placed for the actual test method rather than added as an afterthought.
- 04Assembly that is repeatable
Silkscreen, polarity, orientation and pick-and-place data checked against the assembly method.
- Partitioned by functionBlocks are grouped by signal type so noise stays contained and references stay continuous.
- Thermally reviewedDissipation paths and hot spots are considered during placement, not after the first build.
- Test points placedAccess is planned for the intended method, covering ICT, flying probe and functional test.
- Complete documentationStack-up, notes, drill tables and assembly drawings ship with the fabrication data.

Technologies
Engineering tools and platforms
Layout follows the board: dense digital, high-speed, RF, power or mixed-signal each need a different emphasis.
- Layout environmentMulti-layer layout, rule-driven routing, constraints and differential pair management
- 3D mechanicalOutline, mounting, keepouts and enclosure mating verification in 3D
- Thermal analysisDissipation review and thermal simulation input for hot-spot planning
- Power analysisCurrent path, plane and decoupling strategy for high-current sections
- Fabrication rulesDesign rules matched to the fabricator and assembly house capability
- DocumentationStack-up drawings, fabrication notes and assembly drawings produced from the layout
Layout is constrained by what your fabricator and assembler can actually build. We target their documented capability rather than an idealised rule set.

What buyers usually want to know before scoping this kind of work.
Ask about your requirements →What is the difference between layout and PCB design?
Layout is the physical implementation: stack-up, placement, routing, planes, thermal and assembly data. We treat it as an engineering deliverable with its own review rather than a drawing exercise.
Do you work from our existing schematic and library?
Yes. We can start from your schematic and parts, apply our design rules, and flag electrical concerns we notice while planning the layout.
How do you handle thermal management?
Hot spots are identified during placement, and copper spreading, via strategy and heat paths chosen accordingly. Thermal simulation input is provided where dissipation is significant.
Can you meet our mechanical envelope?
The 3D outline, mounting features, keepouts and connector positions are reviewed against your enclosure before release, so fit is verified rather than assumed.
What testing access do you design in?
Test points are placed for your intended method, such as ICT, flying probe or functional test, and documented so the assembly house can use them.
How do you ensure the board can be built twice the same way?
Gerber, drill, stack-up drawing, fabrication notes, BOM and assembly data are released together as one reviewed, self-consistent package.
