Cost Optimization: A Key Element of Motherboard Design


June 26, 2024

In the PCBA industry, motherboard design is the core of technological innovation and cost control. The current market competition is fierce. According to a report by market research firm Technavio, the global PCBA market is expected to grow at a compound annual growth rate of about 4% by 2025, which highlights the urgency of cost optimization. This article will delve into the cost composition in motherboard design and propose effective cost optimization strategies to provide guidance and inspiration for the industry.

Composition of motherboard design costsComposition of motherboard design costs

  1. Material costs
    In the total cost of motherboard production, material costs can account for up to 50%. The choice of substrate materials is related to thermal management and signal integrity, while component costs involve core components such as processors, memory, and connectors. According to an industry analysis, material costs can be reduced by 10% to 30% through large-volume procurement. Therefore, implementing a batch strategy in material procurement is an effective way to reduce costs.
  2. Design and development costs
    Motherboard design and development links are also key points for cost control. For example, using efficient CAD/EDA tools can shorten the design cycle and reduce human resource consumption. According to statistics, optimizing the design process can save up to 15% of development costs.
  3. Motherboard manufacturing cost
    The motherboard manufacturing cost covers the entire process from prototyping to mass production. An industry survey shows that by improving process flow and increasing production efficiency, manufacturing costs can be reduced by more than 20%. In addition, the application of automated assembly lines has become the main means to reduce labor costs and improve production efficiency.
  4. Logistics and warehousing costs
    Effective logistics and warehousing management can significantly reduce additional costs. For example, the use of a just-in-time inventory system can reduce excess storage and reduce warehousing costs by up to 25%.

Cost optimization strategy

  1. Material selection and substitution
    In material selection, balancing performance and cost is the key. For example, choosing high-performance but low-cost alternative materials, such as FR-4 instead of more expensive high-frequency materials, can save costs without sacrificing performance.
  2. Design optimization
    Simplifying the motherboard design is an effective way to reduce costs. For example, by reducing components of non-core functions, material usage and assembly time can be reduced. In terms of layout optimization, reasonable planning can reduce the number of PCB layers, and reduce manufacturing difficulty and cost.
  3. Manufacturing and assembly efficiency
    It is crucial to choose a cost-effective manufacturing partner. For example, working with a manufacturer that can provide full-process services can reduce intermediate links and reduce comprehensive manufacturing costs.
  4. Testing and Quality Control
    An effective testing strategy can detect problems at an early stage, reducing rework and scrap rates. According to an industry report, a good quality control system can reduce rework costs by up to 30%.


Cost optimization of motherboard design is a comprehensive challenge that requires careful planning and execution of cost control measures while maintaining product performance and quality. Through in-depth analysis and optimization of various links such as materials, design, manufacturing, and testing, companies can stay ahead in the fierce market competition. With the continuous updating of technology, the cost of motherboards will be further compressed. Companies that can do this can win in the competition and occupy more market share.
