Connect the Dots: Design With the Quote in Mind

The quoting process has always been an important part of high-quality PCB prototyping and manufacturing. With supply chain disruptions and intensifying demand for domestically produced boards, that is even more true today. As we’ve previously discussed in recent articles or our book, The Printed Circuit Designer’s Guide to… Designing for Reality, board designs are becoming more complex. Now, so is manufacturing them.

Everything from inventory management to shop floor staffing has gotten harder in recent years, all while the pace of business accelerates. Project development teams need to move fast, and even though designs are more complex, they need their PCB quote requests turned around and their boards manufactured tout de suite.

Designing with the quote in mind means preparing for the quote process while you are still working on the design. Be thinking about the components you will include in your request and whether the complete quote request package contains everything your manufacturer needs to respond within the allotted time.

Complex PCB designs, such as those for UHDI boards, usually require careful analysis by the manufacturer to determine whether specialized manufacturing processes or materials are needed. Juxtaposing elements like a higher layer count and tighter tolerances against an aggressive production deadline takes time to work through.

Give Your Manufacturer Everything They Need

With complex designs in particular, the quote process should be collaborative and focus on value drivers, not on filling information gaps. It is common for key elements to be missing from quote requests, most notably in the BOM. The more complete the quote request, the more collaboration between designer and fabricator focuses on goals such as accelerating production timelines, substituting hard-to-find materials, improving yield, or reducing costs.

Quote requests should include:

• Gerber files: Are they complete? Do they include all necessary specifications for copper layers, solder mask, nomenclature, and drilling?
• Fab drawings: Do they include all required dimensions and tolerances?
• BOM: It is of the utmost importance and should include all material descriptions, reference designators, and required quantities.
• Fabrication specifications: Be extra thorough in defining your specifications, including layer count, board thickness, material, copper weight, surface finish, and color.
• Quote timing and quantity: How many boards do you need, and how fast do you need them? The answer can have a big impact on which manufacturing partner to choose and how much the boards will cost.
• Assembly requirements: Make sure you include a complete list so your boards are prepared for the next production step.
• Design name: Give your design a unique identifier instead of default names like PCB1.

A complete quote request is the price of admission these days, but it isn’t a guarantee of success. Even if the BOM and fab drawings are complete, it doesn’t mean the manufacturer can produce your board. In many instances, the designer and fabricator will have worked together before, making the designer familiar with the fabricator's manufacturing capabilities and material availability. But if you are soliciting a quote from an unfamiliar PCB manufacturer, it makes sense to research ahead of time to ensure their capabilities match your needs.

Know the Quote Process

If you’re an engineer at a large organization that is always developing new electronic products, the PCB quote process is no mystery. But our industry thrives because of innovators who are often less experienced with PCB design and quote solicitation. Designers who don’t have a lot of experience working with fabricators benefit from understanding how a quote request is processed.

In general, these are the steps fabricators take when responding to a quote request:

• Review the quote. Do the Gerber files, BOM, and fab drawings contain everything needed to respond? Can a response be generated as fast as the requestor asks? Are there materials on hand and manufacturing resources available to produce the boards in the requested time window? Do the specs, such as layers, layer thickness, materials, and surface finish, match design requirements?
• Address design ambiguities. Generate questions for the requestor.
• Suggest design changes to improve DFM if an opportunity exists to increase yield or reduce costs.
• Look ahead to assembly. This is done by confirming that the components called out are readily available for assembly now and in the future. If they are not, suggest alternatives.
• Calculate total cost of manufacturing. Include shipping.
• Present the quote to the requester. Negotiate terms as needed to finalize it and generate a production order.

Not every quote turns into an order, so unless you are working with a trusted manufacturer, don’t put all your eggs in one basket. Quick-turn or online quoted orders for simple designs are straightforward for fabricators, so in most cases, soliciting two or three will ensure quick receipt of a response that will meet requirements. Custom, more complex designs will need more back-and-forth with the manufacturer. It makes sense for designers to consult with several manufacturers in order to find one that fits their needs.

Requesting quotes from multiple fabricators will not only give you options but also provide peace of mind regarding completion timing and board costs. Having relationships with multiple fabricators makes sense because, when you are designing with the quote in mind, you focus on successful outcomes rather than tailoring your needs to a single manufacturer’s capabilities.
