Box Building

Auto panel plating line
Box building is a mature and independent or collaborative electronic product that is assembled from the produced PCB, electronic components, cables, parts, firmware, components, and a closed case or chassis. This is the ultimate goal of all printed circuit boards. It is designed by the customer or by our company, then manufactured, assembled, tested, inspected, and tested... Combining circuitry, aesthetics, and industrial design, it also requires project and supply chain management and coordination, systematic quality control, and appropriate testing skills. It is only through this that we are able to work with our customers and provide them with the best possible service.


Box Buliding Description

Preparation of materials and components for each process – e.g. PCBs, components, cables, screws, screws, connectors, housings, etc. as well as materials for small modules and power supplies. as well as some small modules and power supply materials, etc.


That is, from the SMT process to the cable assembly, the above materials and the perfect assembly and connection of the shell, the middle will also use some special materials for fixing, not only rely on screws, screws.


quality testing of the assembled product to ensure that each process meets the process requirements. The quality of welding is observed by the inspection technician, if any poor quality is found, it needs to be manually mended or repaired by the repair technician. After the initial inspection, the next step is to verify whether the product function can be realized, either by the inspection technician using the power-on test or by using the appropriate testing equipment, strictly speaking, each process has a test link. The focus is on functionality, safety and finally on regulatory compliance.


All labels and user manuals are designed according to the customer's needs or scenarios of the product, and the logo or code can be printed on the packaging to make the product look more upgraded.

The number of parts, complexity and production volume of the

product is a great test of the supplier’s management and coordination ability, which is also a criterion for evaluating whether the supplier can help the customer to complete the project.


Some industries that require or rely on the assembly of finished products:

Mechanical equipment

agricultural machinery, construction machinery, food processing equipment

Consumer electronics

communication equipment, home intelligence equipment, small massage devices


servers, switches, routers


analyzers, therapeutic devices, monitors


food and drink, umbrellas, emergency supplies


car recorder, audio-visual equipment, imaging equipment



Material planning as well as design and preparation is the first step in the whole process. Manufacturers need to prepare everything before production, purchase and check all the components for reasonableness and correctness.

Details Include:

Printed Circuit Boards (PCBs produced by LHD and PCBAs assembled with purchased components)

Cables, wires, flexible wires, shielded wires, connectors, etc.

Housings, racks, screws, nuts, screws and other fasteners

Sensors, antennas, metalizers

Labels, QR codes, boxes, documents

Assembly and test tools

A set of the most standardized and high-quality supporting production methods, strict quality control, to ensure that no parts will not be lost and delayed delivery, and can minimize the loss of these components and spare parts may come from suppliers around the world, logistics management and production supply chain management is the most critical.

Manage categorization – into most commonly used parts, expensive parts, special parts and also based on frequency of use.

Define categories and maximum inventory levels for each part

Selection of Critical Parts

prepare planB in time in case any uncertainty occurs

Plan Inventory

plan inventory requirements and lead times and prepare multiple quantities of components where possible.

Purchase Contract Confirmation

ensure that orders are placed immediately, strictly avoiding delays and expediting orders where possible

Supplier Stocking

select and optimize suppliers as close to the local area as reasonably possible.


selection of optimal transportation companies and routes, selection of optimal customs clearance modes for the customer, and perfect shipment within the rules.

Product Inspection And Optimization

The final audit is carried out by the entire test team and requires 100% full testing of each product.

Appearance Inspection

positionality, surfaces, logos, labels and specific appearance requirements.

Functional Calibration

testing the functionality of the product by manual skills or special equipment, with the possibility of upgrading in special cases.

Lifetime Testing

environmental testing through prolonged energization and pressurization.

Impact Testing

testing of the product's adaptability through impact testing under reasonable conditions.

Sound Testing

testing the decibel and sound levels during operation within the product

Lifetime Testing

environmental testing through prolonged energization and pressurization.

In case of any unforeseen circumstances, the product will be repaired, updated, debugged and corrected as quickly as possible.

To ensure that every indicator is correct and meets safety and functionality standards, ensuring that the product is perfect before dispatch.

Packaging And Transportation

After all the processes are completed, the products are assembled in the highest standard shipping boxes or in special boxes that can be customized according to the specificities of the product's appearance.
The above can greatly enhance the unboxing experience of the customer or user, as well as the adaptability and enjoyment of the product.The manufacturer's knowledge of the product makes the packaging perfect and allows for a quicker rollout, eliminating a lot of complicated steps.

To prevent any transportation damage or unpacking damage, to achieve 99.99% protection.

Protective coatings can be applied to special products, serial numbers or special certification labels can be added to the box.

Add foam, bubble wrap, air cushions and high quality cushioning inside the box.

Calculate the most reasonable packing method to save shipping costs or unnecessary expenses.

Quality Control And Reliability

The production of finished assemblies requires interlocking staffs, as well as institutional certifications and a high level of expertise.


ISO, UL, CE, IPC, Environmental Labeling and Protection, Low Carbon Product Certification... Reliable certification enhances the purchasing power of a product when judged by the public...


High precision and automated equipment and test tools, with strict control of the production staff, welding, assembly, test engineers.


with appropriate personnel to take responsibility for testing and managing supplier supplied parts and approvals.


Diversity testing through cross-product standards, high flexibility and scalability.
