PCB Box Build Assembly Services

UETPCBA provides customers with PCB box build assembly services of finished electronic products, involving industrial controllers, consumer electronics, Internet of Things modules, electronic and electrical equipment, etc., by assembling the PCBA circuit board which has been produced and tested together with the shell, wire and motion motor, and packaging it into a complete set of products for delivery to the terminal customer. As an important part of EMS electronic manufacturing, electronic assembly service requires a strong ability of process control and quality control due to many manual operations.

Our company has passed ISO9001:2015 quality management system, ISO13485 medical device management system, IATF16949 automotive electronic quality certification. In the process of PCBA assembly, we strictly implement relevant SOP operation standards, self-inspection, QC full inspection, QA online sampling inspection, OBA sampling inspection before shipment, and other management means. At the same time, the bar code management system is adopted to effectively trace and register good box build assembly manufacturers and defective products, to achieve the ideal goal of assembly through-pass rate and customer quality inspection pass rate.

What information to prepare for box build assembly process


Product Dimensions

You will need to provide the size and weight information of the product to your EMS supplier, as this will affect the assembly layout, packaging, and shipping of the entire box.

Bill of Materials (BOM)

BOM is the most important part of the whole box assembly process, because it specifies each electronic component installed on the product. EMS PCB manufacturers also need to evaluate the cost and delivery time according to BOM. A complete BOM needs to include the exact manufacturer part number, part description, manufacturer, quantity, package, value, and a number of component details.

3D CAD Model

Visualized 3D CAD is critical to the full PCB box build assembly process, including detailed structure and layout diagrams of key components, providing complete, clear 3D CAD models that are easy for EMS suppliers to evaluate quotations and easy to produce, thereby shortening the box construction cycle.

Sample Unit

If complete drawings are not available, sample units can be sent to your box build supplier to create the complete design drawings required to ensure the quality of the product.


During the box build assembly process, in addition to basic electrical tests, if there are specific functional tests, a detailed test plan should be informed to the PCB assembly manufacturer to ensure that the final product can work well and avoid major mistakes of functional dysfunction.
