Larger size micro-LED PCBs require more materials and processing time, so the cost is relatively high. In addition, complexity is also a key factor affecting cost. If the design of the micro-LED PCB is very complex, requiring dense wires and precise layout, then the manufacturing cost will rise. In terms of materials, the choice of substrate material, conductive material, and surface treatment will all have an impact on cost. For example, flexible substrates and metal substrates may be more expensive relative to traditional FR-4 substrates. In addition, quantity is also one of the factors affecting cost. Typically, high-volume production reduces the cost per unit, while low-volume production may result in higher unit costs.

Understanding these cost drivers is critical to budgeting and optimizing production costs. First of all, cost factors must be considered during the design stage, and costs can be reduced by simplifying the design or optimizing the layout. Second, choose the right materials and processing methods to balance cost and quality. At the same time, rationally plan production quantities and formulate appropriate production plans based on actual demand to avoid waste caused by overcapacity or undercapacity. In addition, working with suppliers to seek reasonable purchase prices and production cycles is also an important way to reduce costs.

To sum up, the manufacturing cost of micro-LED PCB is affected by multiple factors, including size, complexity, material and quantity, etc. Understanding and properly managing these cost drivers is of great significance to controlling production costs and improving competitiveness.
