Box Building Service
PCB (Printed Circuit Board) and PCBA (PCB Assembly, components mounted on board) are core elements of electronic products, but they still have to be assembled and integrated with other hardware parts before they become a finished product: wire harness, enclosure (plastic, metal, 3D printed, etc.), display (LCD, TFT, etc.), overlay, logo, fixed by screws, nuts and sometimes glue.
Box Build Assembly Process
- Install PCBs and PCBA into enclosures (plastic PP/ABS, metal aluminum/stainless steel, CNC, sheet metal, 3D printed, etc.)
- Connect the wire harness (sometimes swapped with step 1 above)
- Integrate other mechanical parts, hardware and accessories
- Overlay, label and logo on the outside of the enclosure
- Power on and run functional testing (sometimes set on simulation platforms with assisting accessories)
- Clean and pack into carton box
One-Stop Box Build Integration
Opcba is a one-stop electronics manufacturer that provides box building services, which can save customers a lot of labor and time, such as EMS (Electronic Manufacturing Services): from PCB, components, supply chain, PCBA to final electronic products. When customers receive well tested electronic products, they only need to inspect and test them again to ensure quality and ship them directly to the end user.
When the customer’s other parts supply chain is also in China, box manufacturing services matter even more: they can cooperate with various suppliers to collect all parts together for final assembly and integration, and then ship them as final electronic products.
If You Need Box Building Service
- Provide other parts to Opcba
- Provide an assembly process instruction (SOP)
- Provide the function testing process (teach us how to test the products: firmware, software, how to flash, power supply A/V, simulators, output test)
You are welcome to contact Opcba whenever you need PCB, PCBA and box build service.
