The PCB-to-Product Gap
Many hardware teams are strong on electronics but less experienced in mechanical product design. The result is often an enclosure that doesn't fit properly, a connector in the wrong location, assembly that's difficult at scale, or a design that can't be injection molded as-is.
NTE Lab integrates mechanical and electronics thinking throughout the enclosure development process, so the physical product works as well as the electronics inside it.
Scope of Work
Plastic enclosures designed for injection molding from the start. Draft angles, wall thicknesses, snap fits, and cosmetic requirements are all addressed during design (not after).
PCB registration, standoff strategy, heat sink interfaces, and mechanical clearances. The electronics and the enclosure are designed together, not in sequence.
Every external interface planned with care: tactile feel, IP sealing, panel retention, display stack-up, and antenna clearance where applicable.
Assembly sequence, fastener selection, cable management, and serviceability are built into the design. DFM review ensures the enclosure can be manufactured at production volume.
Additional Considerations
How We Engage
We review your PCB layout, PCBA envelope, connector locations, thermal requirements, and any existing mechanical constraints.
Enclosure concepts are developed around your electronics, with manufacturability considered from the first sketch.
Full CAD development including PCB mounting, interface elements, and internal architecture.
Design reviewed against injection molding requirements before any prototype parts are produced.
What You Receive
Native and STEP files for every enclosure component, ready for prototype and tooling vendors.
Dimensioned drawings with tolerances, finishes, and critical-to-function callouts.
Mounting, standoff, connector, and interface documentation tied to your board revision.
Wall thickness, draft, ribs, gates, and parting-line review captured in a written report.
Complete mechanical bill of materials with vendors, finishes, and indicative costs.
Vendor selection, quoting, and part inspection for SLA, CNC, or soft tooling runs.
Step-by-step assembly notes and basic test guidance for pilot builds.
A consolidated release package your contract manufacturer can quote and tool from.
Frequently Asked Questions
Yes. This is our primary PCB-to-Product workflow. We take your existing PCB layout, dimensions, and connector locations as the starting point and design the entire enclosure around your electronics. The PCB drives the mechanical design, not the other way around.
To begin, we need your PCB outline dimensions, component heights (or a STEP file of the PCBA), connector locations and types, and any environmental or cosmetic requirements. If you have a board STEP export from your ECAD tool, that is ideal. We can also work from datasheets and dimensional drawings.
Absolutely. Every external interface is planned in detail: USB, power, and antenna connectors; tactile buttons and switches; display stack-up and light pipes; thermal management including heat sink interfaces, vents, and thermal pads. These are integrated from the concept stage, not added after the enclosure is designed.
Yes. We support the full path from PCB enclosure concept through prototype parts (3D printing, CNC, or soft tooling) to injection molding readiness. DFM review is included in the design process so the enclosure is ready for production tooling without redesign.
