If your printed circuit boards fail, so does your product. Your printed circuit boards (PCBs) are the brain of nearly every electronic product today, and they should work perfectly. So, identifying a good manufacturer is one of the most important decisions your hardware team can make. When it comes to choosing a PCB assembly manufacturer, it's not all about the cost. While low price quotations may be appealing, it can result in costly rework, missed delivery schedules and poor brand reputation if the product doesn't work. You want a manufacturer that can meet your technical specifications, accommodate your growth, and produce high-quality products.
There are thousands of PCB assembly manufacturers around the world - so how do you choose? By honing in on a few key factors, you can find a partner that matches your manufacturing needs.
To ensure you make the right choice for your next project, here are six tips for selecting a PCB assembly supplier.
6 Tips for Choosing the Right PCB Assembly Manufacturer
1. Evaluate Their Industry Knowledge and Specializations
Electronics aren't all the same and neither are the companies that make them. A company that builds basic consumer electronics may not have the expertise necessary to build parts with the tight tolerances needed for aerospace or medical equipment.
Examine the manufacturer's history to determine if they have relevant experience. Request case studies and references from former customers who manufactured similar products. An expert manufacturer will also foresee potential problems with your design and provide Design for Manufacturability (DFM) feedback to help you save time and money.
2. Check for Quality Certifications and Standards
Quality control is crucial for PCB assembly. The simplest way to confirm the manufacturer's quality standards is to look at their certifications.
ISO 9001 is the bare minimum, as it shows a foundation in quality management systems. You may need to check for more specific certifications depending on your industry. For example, medical devices can require ISO 13485, while parts for the automotive industry typically require IATF 16949. Ask for proof of these certificates to confirm they comply with your standards.
3. Evaluate Their Manufacturing Capabilities
Your manufacturing partner should have the technical expertise and equipment for your design needs. While some manufacturers may have expertise only in rigid PCBs, others can adeptly handle flex or rigid-flex PCBs.
Inquire about their capability to produce both Surface Mount Technology (SMT) and Through-Hole boards. Ask about their production capacity too. A manufacturer might be great at small volume, fast turn prototyping but not have the resources to ramp up to large production runs when your product becomes successful. Having a manufacturer that can handle both prototyping and production keeps all of your project needs in-house.
4. Review Their Supply Chain Management
The electronics supply chain is a high-risk area. Your manufacturer cannot produce if they are missing components.
Inquire about partners' supply chain management. Do they work with established component distributors? How do they manage end-of-life (EOL) parts and shortages? A reputable manufacturer will have procurement specialists that can track down elusive parts without ever using counterfeit components that might compromise the quality of your product.
5. Understand Their Testing and Inspection Processes
No assembly process is 100 percent error-free. The key is to detect these faults before the boards leave the factory. An effective testing process is a sure sign of a quality manufacturer.
Ask them about their testing procedures. Essentially, they should use Automated Optical Inspection (AOI) for visual inspection to look for component omissions or solder defects. X-ray testing is essential for complex boards, particularly to check for hidden solder connections, such as Ball Grid Array (BGA) components. Finally, check if they provide In-Circuit Testing (ICT) or functional testing to ensure the PCB operates precisely as expected with power applied.
6. Consider Communication and Customer Support
Great technical skills are not much good if you can't get hold of a project manager in an emergency. Effective, open communication is essential, particularly when working with a manufacturer in a different time zone.
Take note of how they respond to your initial enquiries. Are they responsive? Do they address your technical concerns or give you general answers? A great manufacturer is an extension of your staff. They should give you weekly production reports, keep the lines open for engineering changes and have an account manager to oversee the entire process.
Conclusion
Selecting a PCB assembly manufacturer takes time, planning and the right questions. By taking into account their industry knowledge, quality certifications, manufacturing capabilities, supply chain stability, quality control and testing procedures, as well as their communication style, you can effectively minimize your risks.
Thoroughly screening potential partners means you'll have your electronic products in your customers' hands on time, on budget, and with flawless performance. To begin, ask for quotes and tour their facilities, and select the manufacturers who make your success their success.
