2.2 Vertical Integration of Supply Chains
Many Chinese PCB manufacturers have adopted a vertically integrated business model. This means they not only produce PCBs but also manufacture or source key components and materials within their own network. Such integration allows for better control over costs and quality, leading to more competitive pricing.
2.3 Lower Material Transportation Costs Within China
The strategic location of PCB factories near raw material suppliers significantly reduces transportation costs. The well-developed transportation infrastructure within China’s manufacturing hubs further enhances this advantage, allowing for quick and cost-effective movement of materials and finished products.
