Why is it so Difficult to Source PCBs ?
In fact, it is not difficult to find the Source PCBs, unless the manufacturing process requirements of PCB are extremely special, such as tolerance, line width, line spacing, board thickness, HDI, etc. But when it comes to sourcing the right PCBs, supply chain disruptions, material shortages, and cost overruns often seem never-ending. This can make completing a project within budget and getting to market quickly seem like an impossible hurdle to overcome.
1.Complex Design Requirements
- Flexibility: As electronic devices get smaller and do more, the demand for flexible PCBs is growing. These PCBs often cost more to make and require more complex assembly.
- Signal Integrity: For products like IoT devices, it is important to keep the signals clean. This means separating the analog and digital circuits. This adds complexity to the thermal management and design.
- Sustainability: As more people want to use green materials and processes, it can take longer and cost more to get the materials you need because they are not as available.
2.Cost Factors in PCB Assembly
- Component Density: More components per board increase complexity and cost.
- Type of Soldering: Lead-free soldering can be more expensive.
- Testing and Quality Assurance: Extensive testing can add to the cost.
3.Supply Chain Disruptions
- The materials required for PCBs, such as copper and specific high-grade resins, can be subject to market fluctuations and scarcity.
- The rising demand for copper, driven by advancements in 5G technology and electric vehicles, exacerbates these supply issues.
4.Limited Local Suppliers
- Finding reliable local PCB suppliers can be a challenge depending on the location. Local sourcing, while beneficial for reducing shipping costs and easing collaboration, may be restricted by the limited availability of suitable suppliers who have the necessary materials and technology.
Key Strategies for Source PCBs
When sourcing PCBs, prioritize finding a manufacturer that specifically suits your unique needs, rather than chasing the so-called "best" provider. Emphasize stability in your procurement strategy to ensure consistent quality and cost-efficiency. Always thoroughly verify a manufacturer's reliability through visits and prototype tests before making long-term commitments. This approach will help you secure a dependable PCB sourcing partnership.
- Find Reliable Suppliers: Partner with manufacturers who have a good reputation for quality and on-time delivery.
- Use Advanced Design Tools: Utilize PCB design software to optimize designs and eliminate errors before production.
- Diversify Your Sources: Work with multiple suppliers and consider different regions to reduce dependence and manage risks.
- Manage Your Inventory: Keep safety stock and consider just-in-time inventory to balance having enough stock without excess.
- Stay Up-to-Date on Industry Trends: Stay informed about technology changes, material availability, and regulatory compliance to make informed decisions.
- Perform Regular Quality Checks: Establish a strict quality control process with regular checks during and after production.
- Negotiate Flexible Contracts: Aim for flexible purchasing terms to handle changes in demand and ensure scalability.
