Designing for Cost-Efficiency: Practical Strategies for Electronics Professionals
When it comes to PCB manufacturing, cost-efficiency doesn’t mean cutting corners. It’s about making smart decisions throughout the design and manufacturing process. Here are eleven practical strategies to help you optimize your PCB designs for cost-efficiency:
1. Minimize PCB Size
Size is a crucial factor in PCB design. Larger PCBs require more materials and take up more space during the manufacturing process, leading to higher costs.
However, making your PCB too small can also increase costs, as it requires precision equipment for assembly. So, striking the right balance is key.
Ensure your PCB has all the necessary components and functionality, but avoid unnecessary increases in size. For instance, a 100mm x 100mm PCB will cost more than a 50mm x 50mm PCB due to the increased material usage.
Remember, the goal is not to make your PCB as small as possible, but to optimize size and complexity to manage costs effectively.
2. Prioritize Quality Materials
Opting for cheaper materials might seem like a good way to cut costs, but this can lead to problems down the line. Low-quality materials can result in PCBs that fail prematurely, leading to higher costs in the long run due to rework or replacement.
Instead of choosing the cheapest option, prioritize quality. For example, using FR-4 material, which is standard and reliable, might cost more upfront than a cheaper alternative, but it will save you money in the long run due to its durability and performance.
3. Stick to Standard Board Shapes
The shape of your PCB can significantly impact manufacturing costs. Non-standard shapes require specialized tools and processes, leading to higher costs.
Unless your design requires a unique shape for a specific reason, it’s generally more cost-effective to stick to standard square and rectangular shapes. A circular or triangular PCB might look interesting, but the additional costs associated with these shapes could outweigh the aesthetic benefits.
4. Maintain Minimum Spacing Requirements
The spacing between copper objects such as pads and tracks can also affect costs. As spacing decreases, the need for precision machinery increases, leading to higher costs.
Always check with your manufacturer for their specific spacing requirements and design your PCB accordingly. For example, if your manufacturer’s minimum spacing requirement is 0.1mm, ensure that your design adheres to this specification to avoid unnecessary costs.
5. Optimize Hole Diameter
Drilling holes in a PCB isn’t just a matter of punching through the board. The size of the holes matters, and it can significantly impact the cost of your PCB. Smaller holes require precision machinery for drilling, which can increase costs.
So, how do you strike a balance? Aim to use the largest diameter possible for holes to keep costs down, while still meeting your design requirements. For instance, a hole diameter of 0.3mm might be more cost-effective than a 0.1mm hole, as the larger hole can be drilled with less precision equipment.
But remember, don’t compromise the functionality and performance of your PCB for the sake of cost. If your design requires a smaller hole, then it’s a necessary cost.
6. Choose the Right Via for the Design
The type of via used in your PCB design can also impact costs. There are several types of vias, including through-hole, blind, and buried vias.
Through-hole vias are the most common and cost-effective. They go through the entire board, allowing connections between all the layers. On the other hand, blind and buried vias connect only certain layers and require more complex manufacturing processes, making them more expensive.
Unless your design requires high density or high frequency, it’s generally more cost-effective to stick with through-hole vias. For example, a design with 100 through-hole vias might cost less than a design with 50 blind vias and 50 buried vias due to the increased manufacturing complexity of the latter.
7. Limit Extra Layers
Each additional layer in your PCB design increases the cost, as it requires additional materials and processing. Keep your design as compact as possible and only use as many layers as necessary to meet your design requirements.
For instance, if you’re designing a two-layer PCB, the cost per unit might be around $0.145 for a batch of 1000 units. However, if you can optimize your design to fit into a single-layer PCB, the cost per unit could drop to less than $0.07. That’s a significant cost reduction just by limiting the number of layers in your design. Remember, keep your design as compact as possible and only use as many layers as necessary to meet your design requirements.
8. Optimize Design for Panelization
Panelization is a process where multiple PCBs are grouped together for manufacturing. This not only improves the utilization of board material but also reduces the overall production time, leading to significant cost savings.
For instance, if you have multiple PCB designs that are part of the same project or system, and they are required in the same quantities, instead of manufacturing them individually, you could group these designs together into a single panel. This would reduce the amount of wasted board material and make the manufacturing process more efficient, leading to lower costs.
This strategy is particularly beneficial if you’re working on multiple projects or if you have several small-sized PCBs. By combining these into a single panel, you can achieve economies of scale and significantly reduce your manufacturing costs.
However, it’s important to note that panelization requires careful planning to ensure that the PCBs can be easily separated after manufacturing without damaging the circuits. This involves deciding between methods such as V-groove or ‘V-cut’ and ‘tab-route’ or ‘stamp hole’ for separating the boards. Each method has its own advantages and considerations, and the choice depends on factors such as the board design and the assembly process.
9. Use Industry Standard Sizes and Components
Using standard sizes and components can make the manufacturing process more efficient and cost-effective. Unique components that require manual assembly can drive up costs, so it’s generally best to stick with standard components whenever possible.
For instance, using a 0603 size resistor or capacitor, which is a common standard, would be more cost-effective than using a less common size like 01005. The smaller the component, the more precision is required for placement, which can increase assembly costs.
Similarly, using standard IC packages like SOIC or QFP can be more cost-effective than using less common packages like BGA. The more complex the package, the more complex the assembly process, which can increase costs.
10. Prefer Surface Mount Components
Surface mount technology (SMT) has become the standard for PCB assembly due to its efficiency and cost-effectiveness. Surface mount components can reduce the number of holes needed in your PCB, simplifying the manufacturing process and reducing costs.
SMT components are also generally smaller than their through-hole counterparts, which can help to reduce the size of your PCB. Moreover, the assembly process for SMT is typically faster and less labor-intensive than through-hole assembly, which can lead to further cost savings.
Unless your design is particularly complex or requires the use of specific through-hole components, it’s generally beneficial to opt for surface mount components whenever possible.
11. Design for Manufacturability (DFM)
Design for Manufacturability (DFM) is a design approach that focuses on simplifying the manufacturing process to reduce production costs. This involves considering factors such as the ease of fabrication, assembly, testing, and procurement during the design phase.
For instance, ensuring that components are not placed too close together can make the PCB easier to assemble, reducing the risk of errors and rework. Similarly, using common component values across your design can simplify procurement and potentially reduce costs due to bulk purchasing.
DFM is a broad topic that covers many aspects of PCB design, but the key takeaway is that considering the manufacturing process during the design phase can lead to significant cost savings.
By implementing these strategies, you can significantly reduce the cost of your PCB projects without compromising on quality or performance. Remember, cost-efficiency in PCB manufacturing is not just about reducing costs, but also about maximizing value. With these strategies in hand, you’re well-equipped to design PCBs that are both cost-effective and high-performing.
