Navigating the PCB assembly supply chain requires careful consideration when choosing between small batch and large batch production. Small batch production is ideal for new products, offering flexibility for testing and adjustments based on market feedback, while large batch production suits mature products with stable demand. Key factors to evaluate include demand volatility, inventory management, financial impact, supply chain flexibility, lead time, quality control, automation, customization needs, and supplier capabilities. Small batches reduce inventory risks and enable faster delivery but may incur higher initial costs. Large batches lower unit costs but require stricter quality control and tie up more capital. By analyzing these aspects, manufacturers can select the optimal production strategy to enhance efficiency, reduce costs, and ensure successful product launches.
