OEM / ODM · Full Industry Chain
From your idea
to mass production.
You only need a concept. Besteam handles everything else — circuit design, PCB layout, firmware, prototyping, testing, certification and manufacturing of your custom PoE power module.
You only need an idea
A concept, a target spec, or even a competitor sample — we take it from there.
One full industry chain
Design, PCB, firmware, prototyping, certification and production — all under one roof.
Your brand, your IP
OEM/ODM under NDA. The design and branding are yours.
Full Industry Chain
One partner, idea to product
Every stage handled in-house — no outsourcing, no hand-offs, no surprises.
1. Requirement & Idea
Tell us the application, output and constraints. Our engineers turn it into a complete, reviewed specification.
2. Circuit Design
We design the PoE-PD front-end and DC-DC topology from scratch — schematic, BOM and SPICE simulation.
3. PCB Layout
Multi-layer PCB layout optimised for EMC, thermals, creepage and your target form factor.
4. Prototyping
Quick-turn fabrication and assembly of working prototypes for your validation, typically in 2–4 weeks.
5. Testing & Validation
Electrical, load, thermal, surge and safety testing against IEEE 802.3af/at/bt and your requirements.
6. Certification
We support CE, FCC, RoHS and REACH so your product is ready for global markets.
7. Mass Production
Our own SMT and assembly lines deliver stable capacity with consistent, repeatable quality.
8. QC & Delivery
100% functional testing, packaging to your brand and reliable worldwide shipping.


Engineering & Design
Real circuit design, in-house
Our engineers design the complete PoE powered-device front-end and DC-DC stage from first principles — not a relabelled reference board. Every project gets a clean schematic, an optimised BOM and a multi-layer PCB laid out for EMC, thermal performance and safety creepage.
- Schematic capture, SPICE simulation & BOM optimisation
- Multi-layer PCB layout with EMC & thermal focus
- Isolated and non-isolated topologies
- Firmware & smart-control options on request

Manufacturing
Our own production lines
Designs are built on our own SMT and assembly lines — so quality, capacity and lead times stay under our control. Automated placement, reflow and AOI keep every board consistent, from pilot runs to high-volume production.
- High-speed SMT placement & reflow
- Automated optical inspection (AOI)
- Stable capacity for scaling volumes
- Brand & packaging to your specification



Quality & Testing
Tested to standard, 100%
Every unit is functionally tested before it ships. We validate against IEEE 802.3af/at/bt and your own acceptance criteria — including load, thermal, surge and safety testing — so what reaches your customer simply works.
- 100% functional test on every unit
- IEEE 802.3af/at/bt compliance testing
- Load, thermal, surge & high-pot safety tests
- Optional aging / burn-in screening

FAQ
Common questions
I only have an idea, not a spec. Can you still help?
Yes — that is exactly our model. Share the application and rough requirements and our engineers will define the full specification, recommend a topology and quote feasibility for free.
Do you protect our design and confidentiality?
Absolutely. We sign an NDA on request. The schematic, PCB, firmware and branding we develop for you are your intellectual property.
What is the minimum order quantity?
We support low-volume pilot runs through to high-volume mass production. Tell us your target volume and we will advise the most cost-effective approach.
How long does a custom project take?
Design plus first samples is typically 2–4 weeks. Mass production lead time depends on volume and components, usually 2–4 weeks after sample approval.
Which certifications can you support?
We design to and support CE, FCC, RoHS and REACH, plus IEEE 802.3af/at/bt compliance testing for global market access.
