PCBONLINE's PCB box-build assembly service not only installs the PCBA/system within the enclosure and integrates wiring harnesses, but also provides the enclosures, all required molds/jigs, parts, harnesses, PCBA manufacturing, system-level testing, labelling & packaging, and certification assistance to deliver the final product.
We offer professional DFM (design for manufacturing) and one-on-one engineering support, and turnkey PCB box-build assembly service from prototype to bulk production. We aim to help the success of our target customers — OEM product companies, terminal companies, solution companies, and business makers and be their long-term manufacturing partner.
Engineering support: We provide one-on-one engineering support and solve technical issues throughout the project.PCB fabrication and component sourcing: We manufacture any PCB meeting the product requirements, such as high-density-interconnect and high-frequency.Jig and mold design and manufacturing: Our engineering team designs PCB stencils and jigs for testing, fabrication, and assembly, and co-designs the molds with our mold partners for the custom enclosure, parts, wiring harnesses, and accessory connector.Custom enclosure, part, wiring harness, and accessory manufacturing: We have custom parts, wiring harnesses, and accessories from manufacturers with whom we maintain long-term cooperation. Our supply chain procures the standard ones from reliable channels.PCBA manufacturing and value-added: PCBONLINE offers turnkey PCB assembly. After PCB assembly, we offer IC programming, functional testing, conformal coating, and aging testing.Box-build assembly and system-level testing: With the PCBA, enclosure, wiring harness, custom parts, and accessories, we install the PCBA and internal mechanical parts inside the enclosure and integrate the wiring harnesses and accessories. Then we perform system-level testing.Labelling and certification assistance: We can help our client get final-product certifications meeting the target market's requirements by finding out the authoritative testing labs and certification institutions. The labelling and packaging follow customer requirements.

PCBONLINE, founded in 2005, has two large advanced PCB manufacturing bases, one turnkey PCB assembly factory, and a smart OEM center with a professional engineering and R&D team. We have powerful strength in PCBA manufacturing, value-added, component/enclosure/harness/part procurement, box-build assembly, and engineering support.
Engineering support: Our one-on-one engineering support includes PCB layout, BOM (Bill of Materials), component PCB pad pattern and orientation, testing, PCBA 3D drawing, and enclosure design. We can also take part in the R&D from the early development stage.Component sourcing: With a turnkey PCB assembly factory, we source components from original component factories and audited first-class suppliers. We have active and passive components in stock and provide quality and time assurance for component procurement.Enclosure/part/accessory procurement: Our jig and mold manufacturers are long-term partners. We procure from the top three custom enclosure manufacturers in China and local reliable manufacturers and bear responsibility for our procurement.PCBA and value-added: Turnkey PCBA and value-added equipment and processes. Our PCB assembly uses automatic surface-mount and semi-automatic through-hole technologies, with advanced soldering options such as nitrogen reflow and selective soldering.FAE: Our system-level testing on the box-build regards functions, environmental friendliness, reliability, and thermal/power resistance. Our R&D involvement from the early phase prevents possible tricky issues in the field application engineering stage.
So far, we have manufactured many successful box-build assembly projects, including AI servers, IoT robots, Bluetooth devices, wireless long-distance outdoor scales, ESP-based sound/temperature/light control smart devices, Bluetooth modules, 5G modules, creative devices & rotating small appliances using single-chip computers, industrial controls and switches, and battery cell contact systems.
Besides, we optimize your box-build design from the aspect of PCB design to reduce fabrication costs without function and quality sacrifice.

We provide flexible production for PCBA box-build assembly to meet custom requirements. When a customer sends the PCBA box build assembly inquiry to us by email at info@pcbonline.com, our engineering team checks their documents and starts one-on-one enginering support throughout the journey.
DFM: DFM: We study the customer's project requirements systematically and pay attention to details in every aspect, from PCB to enclosure, including functional structural layout, interactive design, system adaptation, prototype drawing, requirement document, program, functions, performance, technology, costs, PCB layout, BOM (bill of materials), and pick-and-place file.
Product box-build sampling: PCBONLINE makes the product sample, including PCB prototyping, prototype assembly, PCBA value-added, mold manufacturing, procurement of the enclosure/harnesses/parts/assassories, and sample box build assembly.
Product testing and certifications: We have system-level testing to ensure the product performs as expected and then have it certified by the certification organization.
Small-run and bulky production: Our customers typically order a small-run production order to try the marketing effect. If the feedback meets their expectation, they order bulk production from us. We wish for win-win cooperation, so we spare no effort to help our customers' product succeed technically!
Applications of PCBA box build assembly:
All IoT applications, including Bluetooth, ESP, Wi-Fi, short and long-distance communication, robots, and smart appliances.Custom appliances that rotate using single-board computers or creative appliances controlled by MCU.
