01 / Who we work with
Built for the small runs other factories turn away.
Many SMT factories avoid low-volume, high-mix orders because frequent line changeovers slow them down. We accept them — and we can also provide the electronics engineering that small product teams often lack.
Hardware start-ups
Early orders are small, but you still need a reliable production partner who will grow with you.
Teams without electronics engineers
Strong in mechanical design or product development, but no in-house electronics department.
Custom & niche products
Specialist or customised products where volumes rarely justify a dedicated production line.
Companies outsourcing production
Where local suppliers are unavailable, immature or too expensive for your volumes.
02 / Services
One partner from circuit board to finished product.
Use one service or combine them. Whether you supply the parts or need sourcing support, we connect board assembly, testing and final assembly.
Box build assembly
Enclosure fitting, wiring, screw fastening, programming, testing and packaging for a finished product.
Box build services →
Electronics design
Power supplies, LED drivers, laser drivers, microcontroller firmware and PC software developed in-house.
Engineering services →
03 / Quality & testing
Inspection agreed around your product.
Test requirements differ from board to board, so we agree the scope with you before production starts.
- AOI (automated optical inspection)
- Microscope inspection and 100% visual inspection
- Firmware programming and functional testing
- Electrical function testing of every unit, on request
- Test plans and test fixtures developed in-house
- Samples for your approval before production

A clear path from enquiry to production.
Tell us about the build
Send production files, or describe the product and the support you need.
Engineering review & quote
We assess materials, assembly, testing and delivery needs, then prepare a quotation.
Approve the samples
Once agreed, samples are built for your evaluation before production.
Production & shipping
Assembly, agreed testing, packaging and export shipment — and repeat orders when you need them.
Frequently asked questions
Do you accept small orders?
Yes. There is generally no fixed minimum order quantity. We support prototype builds, small batches, medium-volume production and repeat orders. Pricing depends on quantity and the complexity of each project.
What should I send for a PCBA quote?
Gerber files, a bill of materials (BOM) with manufacturer part numbers, a pick-and-place file, assembly drawings, the order quantity and any programming or test requirements. If you are at an earlier stage, describe the product and the support you need.
Can you work with customer-supplied components?
Yes. We can work with customer-supplied (consigned) materials, source selected components, or handle full turnkey procurement.
How long does production take?
For PCBA projects using readily available components, procurement and production typically take around 15–20 days. The schedule is confirmed for each project. Development, tooling, special materials and final assembly may need additional time. Urgent requirements can be assessed.
Do you support overseas customers and confidentiality?
Yes. We communicate in English, can sign an NDA, and arrange export packaging, international shipping and customs clearance assistance.
