Understanding Your Project Requirements
Before approaching any manufacturer, you must clearly define your project's specific needs. This foundational step will guide every subsequent decision in the selection process. Start by documenting your technical specifications, including layer count, board dimensions, material requirements, and component density. Consider whether you need single-sided, double-sided, or multi-layer boards, as this dramatically affects both complexity and cost.
Equally important is understanding your volume requirements and timeline constraints. Are you producing a one-off prototype, planning a small batch of 100 units, or preparing for mass production of thousands? Your volume directly influences which manufacturers can serve you effectively and economically. Some specialize in quick-turn prototypes with fast turnaround times, while others excel at high-volume production with optimized pricing for large quantities.
Your budget constraints and quality expectations must also be clearly established from the outset. While it's tempting to always choose the lowest-cost option, understanding the relationship between price and quality in PCB manufacturing is crucial. Higher-end applications requiring exceptional reliability may justify premium pricing, while simple consumer electronics might allow for more cost-focused decisions.
Evaluating Manufacturing Capabilities
Technical capabilities form the backbone of any manufacturer's value proposition. Begin by assessing their equipment and technology infrastructure. Modern PCB manufacturing requires sophisticated machinery for drilling, plating, etching, and testing. Manufacturers using outdated equipment may struggle with tight tolerances, fine-pitch components, or advanced materials like high-frequency substrates.
Layer count capability is particularly important for complex designs. While many manufacturers can handle standard 2-4 layer boards, fewer can reliably produce 12+ layer boards with maintained signal integrity. If your design requires high layer counts, blind vias, or buried vias, ensure your chosen manufacturer has proven experience with these advanced techniques.
Material handling capabilities vary significantly between manufacturers. Standard FR-4 is universally available, but specialized materials like polyimide flex circuits, metal-core PCBs for LED applications, or high-frequency materials for RF applications require specific expertise and equipment. Verify that your manufacturer can source and process the exact materials your design requires.
Surface finish options represent another critical capability area. While HASL (Hot Air Solder Leveling) remains the most economical option, many modern applications require ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservative), or other advanced finishes. Each finish has implications for solderability, shelf life, and cost, so ensure your manufacturer offers the appropriate options for your application.
Quality Standards and Certifications
Quality in PCB manufacturing isn't just about avoiding defects; it's about consistent, repeatable processes that deliver reliable products. Look for manufacturers with relevant industry certifications, starting with ISO for general quality management systems. For aerospace and defense applications, AS certification becomes essential, while automotive projects typically require TS compliance.
IPC standards compliance is fundamental in PCB manufacturing. IPC-A-600 defines acceptability criteria for printed boards, while IPC- covers qualification and performance specifications. Manufacturers should demonstrate adherence to these standards through documentation and testing procedures. Many also pursue IPC- for flexible circuits or other specialized IPC standards relevant to their capabilities.
Understanding a manufacturer's testing and inspection procedures provides insight into their quality commitment. Automated optical inspection (AOI), electrical testing, and impedance control testing should be standard practices. More advanced manufacturers may offer additional services like cross-sectioning analysis, thermal cycling tests, or reliability testing that can be invaluable for critical applications.
Requesting quality metrics and defect rates from potential manufacturers helps quantify their performance. Reputable manufacturers should be able to provide data on their first-pass yield rates, on-time delivery performance, and customer satisfaction scores. These metrics offer objective measures of their operational excellence.
Geographic Considerations and Supply Chain
The geographic location of your PCB manufacturer affects multiple aspects of your project, from cost and lead times to communication and supply chain resilience. Domestic manufacturers typically offer advantages in communication, time zone alignment, and faster shipping, but often at higher costs compared to overseas options.
Asian manufacturers, particularly those in China, Taiwan, and South Korea, dominate the global PCB market and often provide the most competitive pricing for medium to high-volume production. However, longer shipping times, potential language barriers, and supply chain risks must be weighed against cost savings. Recent global events have highlighted the importance of supply chain diversification and the risks of over-reliance on single geographic regions.
Consider the total cost of ownership, not just the unit price. While overseas manufacturing might offer lower per-unit costs, factor in shipping expenses, potential customs delays, inventory carrying costs due to longer lead times, and the hidden costs of communication challenges or quality issues that require rework.
For time-sensitive projects or applications requiring frequent design iterations, proximity becomes more valuable. Domestic manufacturers can often provide faster turnaround times for prototypes and offer easier collaboration for design optimization. The ability to visit the manufacturing facility for critical projects or quality audits may also influence your decision.
Communication and Customer Service
Effective communication forms the foundation of successful manufacturer relationships. Evaluate potential partners based on their responsiveness, technical competency of their sales and engineering teams, and their ability to communicate clearly in your preferred language. Manufacturers should provide dedicated account management and engineering support throughout your project lifecycle.
Technical support capabilities vary dramatically between manufacturers. Some offer comprehensive design for manufacturability (DFM) reviews, suggesting optimizations that can improve yield and reduce costs. Others provide only basic manufacturing services with minimal engineering input. For complex projects or companies with limited PCB design experience, choosing a manufacturer with strong technical support can prove invaluable.
Look for manufacturers who proactively communicate about potential issues, schedule changes, or optimization opportunities. The best partners don't just execute your orders; they contribute to your project's success through their expertise and recommendations. This collaborative approach becomes especially important for long-term relationships or evolving product lines.
Pricing Structure and Value Analysis
PCB pricing involves multiple variables that extend beyond simple per-unit costs. Understanding manufacturers' pricing structures helps you make informed decisions and budget accurately for your projects. Most manufacturers base pricing on factors including board size, layer count, quantity, materials, surface finish, and special requirements like controlled impedance or fine-pitch features.
Setup costs and tooling fees can significantly impact total project costs, especially for smaller quantities. Some manufacturers charge substantial setup fees that make small orders economically unfeasible, while others specialize in quick-turn, low-quantity orders with minimal setup charges. Understanding these cost structures helps you choose manufacturers aligned with your volume requirements.

Volume pricing tiers deserve careful analysis, particularly for projects with uncertain demand forecasts. Some manufacturers offer aggressive pricing breaks at specific quantity thresholds, while others provide more linear pricing curves. Consider your projected volumes and the flexibility to adjust quantities without dramatic cost penalties.
Payment terms and financial stability of manufacturers also merit consideration. While established manufacturers typically offer standard payment terms, newer or smaller manufacturers might require different arrangements. Evaluate the financial health of potential partners to ensure they can fulfill long-term commitments and maintain consistent operations.
Making the Final Decision
After evaluating all factors, the selection process often comes down to balancing competing priorities. Create a weighted scoring system that reflects your project's specific priorities, whether that's cost optimization, quality assurance, speed to market, or technical capabilities. This systematic approach helps prevent emotional decision-making and ensures alignment with your project objectives.
Request quotes and samples from your top candidates to make direct comparisons. Many manufacturers offer free or low-cost samples for evaluation, allowing you to assess quality firsthand. Pay attention to packaging, documentation, and overall professionalism in their sample delivery, as these details often reflect their operational standards.
Consider starting with smaller orders or pilot projects before committing to large-volume relationships. This approach allows you to evaluate actual performance against promises and build confidence in your chosen partner. Successful pilot projects can evolve into long-term strategic partnerships that provide competitive advantages through optimized processes and preferential treatment.
Building relationships with multiple qualified manufacturers provides flexibility and risk mitigation. While primary partnerships offer economies of scale and streamlined processes, backup suppliers ensure continuity during capacity constraints, quality issues, or other disruptions.
Conclusion
Choosing the right PCB manufacturer requires balancing technical capabilities, quality standards, cost considerations, and service levels against your specific project requirements. Success depends on thorough upfront evaluation, clear communication of requirements, and ongoing relationship management. The investment in selecting the right manufacturing partner pays dividends through improved product quality, reduced time to market, and enhanced competitive positioning. Take time to evaluate options systematically, start with pilot projects when possible, and build long-term relationships with manufacturers who demonstrate consistent value delivery for your specific applications.
We ran into Ben Jordan of Jordan DSP LLC at the PCB West and had the privilege of discussing the best techniques for designing PCB antennas. Watch the complete video to learn more.
How do PCB antennas work?
Ben Jordan: It’s exactly like a high-speed digital trace that unintentionally behaves as an antenna. PCB antennas move charge in certain shapes which gives rise to propagation. They could be a stick of wire on a board surface or a dipole working with high-frequency alternate currents. In a high-speed circuit, the ground plane holds the charge so it doesn’t propagate. We do this to avoid noise and EMI problems. However, an antenna has to intentionally radiate and receive waves. Hence, they are deliberately kept away from the reference plane.
In what kind of electronics are antennas mostly used?
Ben Jordan: Everything’s wireless now. Antennas are incorporated from scanning information on a (near field communications) to sparse wide area networks using LoRaWAN. Hence, it’s necessary for PCB designers to learn about RF microwave antennas. You need to choose the right type and size of antenna that operates at the right frequencies. In addition, measure and match its impedance with a low-noise amplifier or a wireless microcontroller.
What are the key factors to design antennas for RF and microwaves?
Ben Jordan: First, determine frequency ranges like center frequency and bandwidth of operation. Also, understand the power level required. Next, size the antenna based on the layer stack. Set all the design constraints. These are all iterative processes. From the choice of material to the size of the antenna, it all plays a significant role.

What are your best practices to design layer stacks for antenna boards?
Ben Jordan: The whole board stack-up doesn’t have to be of the same material. Usually, specialized materials are used on the surface layers. For example, you may have digital, RF, and analog signals in mixed-signal PCB. The key is to select the right material, but include it with cores and prepregs that are more general-purpose and stronger. Additionally, choose stack-up thicknesses suitable for RF and microwave PCBs and make manufacturing more economical. Once you have built a good layer stack, consult your fabricator for their insights.
Could you explain how to separate two patch antennas on a PCB?
Ben Jordan: Multiple patch antennas are used for more power and sensitivity. These are put into an array and those arrays are spaced at half or quarter wavelengths depending on the orientation. The direction should allow the far-field signals to increase signal strength or sensitivity.
What are your recommendations to mount PCB antennas?
Ben Jordan: There are two critical things for mounting antennas:
- Directionality: Typical IoT applications use fairly omnidirectional antennas. However, if they’re over a ground plane, then it will deplete the energy from the EM field of the antenna. Hence, it will disturb signal propagation. You can avoid this by using patches as the ground plane is a part of the transmission. Other types like inverted F and meandering antennas should be mounted away from the ground layer. But you should still connect them to a reference plane.
- Diversity: Mount antenna components at 90-degree angles to each other to improve reception over the entire sphere around the product.
What are the best materials for circuits with antennas?
Ben Jordan: The best materials are low-loss dielectrics, but it depends on the application. If it is for low-power and low-range ISM band applications like IoT, wifi, and Bluetooth, you can use regular FR4. When you are dealing with high power or longer range, you should consider loss and opt for Rogers dielectrics or other ceramic-filled materials.
Due to the lower Dk value, you need a bigger size object to match impedances. On the contrary, they have lower-loss tangents which are extremely important in patch arrays for increased power to travel long distances.
To learn how we routed antenna signals and differential pairs in a compact PCB layout, see our case study, designing microcontroller and functional PCBs with an antenna.
Are there specific tools that you recommend?
Ben Jordan: You definitely need a good simulation tool. ADS, Pathwave, Ansys, and HFSS, are flagship tools that model and simulate wave propagation of the microwave and RF designs. Subsequently, if you’re on a tight budget then you can use free tools like Qucs (open source). It has a harmonic balance and FTDD solver for electromagnetic simulation. As for designing the main printed circuit board, you have software packages like Altium, Eagle, and Auto Desk fusion 360. All these tools facilitate RF and microwave designing.
Ben Jordan is a computer system engineer from the University of Southern Queensland. He has 20 years of experience in the EDA industry. Before starting his own consulting and training company, he worked for Altium and Autodesk.
