1. Understanding PCB, PCBA, and Box Build Assembly

PCB: a bare board containing unassembled electronic components.

PCBBA Manufacturing: This process primarily involves component mounting (SMT or THT), soldering (reflow soldering or wave soldering), and testing (AOI, X-ray, ICT, etc.). It is an intermediate stage in the manufacturing process, focusing on the production and functional implementation of the circuit board.

Box build assembly: Assembling the PCBA-processed circuit board with other components (such as housings, connectors, heat sinks, etc.) to form a complete electronic product.

2. Box Build Quote Service

When your project goes beyond just PCBs or PCBAs, requiring the integration of circuit boards, components, wiring harnesses, enclosures, structural parts, functional testing, final assembly, and even complete system shipment into a single system, box build quote is designed for these complex needs.

Contents of Box Build Quote

On the intelligent quotation platform, you can upload complete project materials (e.g., a ZIP archive containing Gerber, BOM, structural diagrams, wiring harness list, enclosure drawings, etc.). After submission, a professional engineer will provide you with a quotation.

The Box Build Quote quotation will include the following:

• BOM Quotation List
• PCB board fabrication: number of layers, multilayer PCB, HDI, impedance board, PCB materials, surface treatment
• PCBA surface mount: SMT, DIP, THT assembly, wave soldering, etc
• Materials and labor assembly: wire harnesses, cables, connectors, power cords, shielded cables, ribbon cables, wire harness assemblies, etc.
• Enclosure installation: plastic shells, metal shells, brackets, heatsinks, chassis
• System-Level testing: Post-assembly FCT/ICT/aging tests/complete functional tests, environmental tests to ensure overall product quality upon shipment.
• Transparent pricing throughout the process: the quotation includes material costs, assembly costs, testing fees, structural component, and assembly labor costs.

3. Advantages of Choosing SCSPCBA Box Build Quote

Compared to traditional suppliers who only quote for PCBs or PCBAs, SCSPCBA offers a turnkey service encompassing PCB + SMT + testing + final assembly. This integrates the entire process from raw material procurement to final product assembly, reducing intermediaries, providing greater transparency, stronger supply chain integration capabilities, and a more comprehensive integrated manufacturing solution, resulting in better cost control.

(1) Turnkey Service

• Cost Control
  From raw material procurement → PCB → PCBA → wire harness materials → complete assembly → testing → packaging and shipping, SCSPCBA handles everything in one integrated process, avoiding rework caused by communication errors between suppliers.
• Rapid Quotation
  Based on an AI + data-driven quotation system, including BOM service, PCB quotation, PCBA quotation, and finished product assembly, a complete quotation can be obtained in a short time after uploading project information, eliminating the need for multiple rounds of manual confirmation and greatly shortening the initial cycle.
• Data Traceability and Clear Responsibility
  Every component, wire, structural part, processing technology, and testing procedure is meticulously recorded. In case of quality issues, responsibility is clearly defined, eliminating the complexities of investigation and evidence collection. The one-stop service manufacturer handles all problems.
• Customization Services
  One-stop PCBA services offer a streamlined approach to product customization. All production processes can be more collaborative, which is especially important for ODM projects.
• Adaptable to High Reliability Requirements
  Supports complex PCBs, mixed SMT/DIP/BGA, wire harnesses and structural components, high-density assembly, and testing-inspection. Suitable for high-standard industries such as automotive electronics, medical devices, industrial control, and communication equipment.
• From Prototype to Mass Production
  Whether you need a few prototypes or thousands of units for mass production, Box Build services can adapt, eliminating the need for scattered suppliers or coordination concerns.

(3) Every Quote is Backed by a real PCB Assembly factory

SCSPCBA box build quotes are not from an intermediary platform, nor are they generated in isolation; they are verified through actual production capabilities.
All prices are based on the following factors:

• Automated Optical Inspection (AOI), X-ray inspection, vibration testing, thermal cycling testing, and salt spray testing.
• Each factory is equipped with automated SMT production lines and DIP production systems.
• In-Circuit Testing (ICT) and functional testing.
• Certified to ISO 9001, IAFT, RoHS, UL, and IPC-A-610 standards, ensuring production capacity for automotive, medical, and consumer electronics products.
• Continuous engineering audits for complex projects.

This ensures that quotes reflect actual production conditions, rather than being based on assumptions.

(4) Intelligent BOM Analysis

This is crucial for final assembly pricing. Unlike general-purpose platforms, BOM services include:

• Real-time component availability signals
• Recommended alternative components (same package size and electrical rating)
• Lifecycle status (available/discontinued/already discontinued)
• Cost analysis by quantity level

This is especially important for ODM projects, as BOM decisions impact long-term manufacturability.

4. Box Build Quote ≠ Complete System Assembly Only

Complete PCB assembly pricing is based on end-to-end system integration (PCBA + Housing + Wiring + Sub-components), and also needs to consider various factors, such as:

• Copper Foil Thickness
  Different thicknesses of copper foil have significantly different prices; for example, copper foil ranging from 0.5oz to 3oz will have different prices.
• Solder Mask Type
  Solder mask inks are categorized into photosensitive inks, thermosetting inks, and photocurable inks, with each type having a distinct price.
• Surface Treatment Processes
  PCB copper foil surface treatment processes include flux treatment, OSP anti-oxidation treatment, silver plating, leaded tin plating, lead-free tin plating, electroplating with water gold, electroplating with pure gold, etc. The higher the process level, the higher the price.
• Application Scenarios
  PCBA boards are used in various types of electronic devices, from simple to complex. The complexity of the application scenario will affect the price.
• Signal type
  The choice of PCB layer count depends on the type of signal to be transmitted, such as high-frequency, low-frequency, ground, or power signals. These may require different grounding and isolation methods.
• Hole type
  The choice of via type (e.g., buried vias) will affect the layer count requirement, thus affecting cost.
• Pin density
  Higher pin density requires more layers and increases cost.
• Manufacturing cost
  Multilayer PCBs are more expensive than single-layer PCBs; manufacturing cost is one of the determining factors in choosing the number of layers.

A complete PCB manufacturing and assembly quote needs to be considered comprehensively to ensure that the quote accurately reflects the actual project situation. If you need a specific quote, it is recommended to contact a professional printed circuit board assembly manufacturer and provide detailed design requirements and specifications to obtain an accurate quote.
