Understanding PCB Ordering

Before diving into the various ways to order custom PCBs online, it’s essential to understand the key factors that influence the PCB ordering process. These factors include:

• PCB design: The complexity, size, and layout of your PCB design will impact the manufacturing process and cost.
• Material selection: PCBs can be made from various materials, such as FR-4, aluminum, or flexible substrates, each with unique properties and costs.
• Number of layers: PCBs can have one, two, or multiple layers, depending on the complexity of the circuit and the desired functionality.
• Quantity: The number of PCBs you order will affect the overall cost and lead time.
• Manufacturing specifications: Factors like trace width, hole size, and surface finish will influence the PCB’s performance and cost.

Understanding these factors will help you make informed decisions when ordering custom PCBs online.

Method 1: Online PCB Manufacturers

One of the most popular ways to order custom PCBs online is through dedicated PCB manufacturers. These companies specialize in fabricating PCBs and often offer a wide range of services, from basic prototyping to high-volume production. Some popular online PCB manufacturers include:

• PCBWay
• JLCPCB
• OSH Park
• Seeed Studio
• EasyEDA

To order from an online PCB manufacturer, you typically need to follow these steps:

1. Create your PCB design using CAD software (e.g., Eagle, KiCad, or Altium).
2. Export your design files in a format supported by the manufacturer (e.g., Gerber, ODB++).
3. Upload your design files to the manufacturer’s website.
4. Specify your manufacturing requirements (e.g., material, layers, quantity, and surface finish).
5. Review and approve the order, then proceed with payment.

Online PCB manufacturers often provide instant quotes based on your design and requirements, making it easy to compare prices and lead times. Many also offer additional services, such as PCB Assembly and component sourcing, providing a one-stop-shop for your PCB needs.

Here’s a comparison table of some popular online PCB manufacturers:

Manufacturer	Min. Quantity	Lead Time	Price (10 pcs, 2 layers, 100x100mm)	Additional Services

EasyEDA	5	48 hours	$4.91	Assembly, PCB design service

*Prices and lead times are subject to change and may vary based on specific requirements and promotions.

Method 2: Electronic Component Distributors

Another option for ordering custom PCBs online is through electronic component distributors. These companies primarily focus on selling electronic components but often offer PCB fabrication services as well. Some popular electronic component distributors with PCB fabrication services include:

• Digi-Key
• Mouser Electronics
• Arrow Electronics
• Farnell (Element14)

To order custom PCBs through an electronic component distributor, follow these steps:

1. Create your PCB design using CAD software.
2. Export your design files in a format supported by the distributor.
3. Navigate to the distributor’s PCB fabrication service page.
4. Upload your design files and specify your manufacturing requirements.
5. Review and approve the order, then proceed with payment.

One advantage of using electronic component distributors for PCB fabrication is the potential for consolidated shipping. If you’re already ordering components from the distributor, you can have your custom PCBs shipped along with your other items, saving on shipping costs and streamlining your project logistics.

Here’s a comparison table of PCB fabrication services offered by popular electronic component distributors:

Distributor	PCB Fabrication Service	Lead Time	Price (10 pcs, 2 layers, 100x100mm)	Additional Services
Digi-Key	PCB Builder	5-15 days	$90.50	N/A
Mouser	PCB Service	5-7 days	$138.00	N/A
Arrow	Arrow Digital PCB	7-10 days	$110.00	PCB assembly
Farnell	PCB Service	5-8 days	$100.00	PCB design service

*Prices and lead times are subject to change and may vary based on specific requirements and promotions.

Method 3: Marketplaces and Comparison Platforms

PCB marketplaces and comparison platforms aggregate multiple PCB manufacturers and provide a centralized platform for comparing prices, lead times, and capabilities. These platforms can help you find the best deal for your custom PCB order. Some popular PCB marketplaces and comparison platforms include:

• PCBShopper
• PCBCart
• PCBDirectory
• CircuitHub

To use these platforms, follow these steps:

1. Create your PCB design using CAD software.
2. Export your design files in a format supported by the platform.
3. Upload your design files to the platform and specify your manufacturing requirements.
4. Compare quotes from various manufacturers on the platform.
5. Select the manufacturer that best meets your needs and proceed with the order.

PCB marketplaces and comparison platforms can save you time and effort by providing a single interface for comparing multiple manufacturers. However, it’s essential to carefully review each manufacturer’s capabilities and reputation before placing an order.

Here’s a comparison table of some popular PCB marketplaces and comparison platforms:

Platform	No. of Manufacturers	Instant Quotes	Additional Services
PCBShopper	20+	Yes	N/A
PCBCart	10+	Yes	PCB assembly, 3D printing
PCBDirectory	50+	Yes	N/A
CircuitHub	5+	Yes	PCB assembly

*The number of manufacturers and additional services may vary over time.

Method 4: Freelance Platforms

Freelance platforms like Upwork, Freelancer, and Fiverr connect clients with professionals offering various services, including PCB design and fabrication. If you need help with your PCB design or want to outsource the entire process, consider using a freelance platform.

To order custom PCBs through a freelance platform, follow these steps:

1. Create a project description detailing your PCB requirements, including any design work needed.
2. Post your project on the freelance platform and wait for bids from PCB designers and fabricators.
3. Review the bids, portfolios, and ratings of the freelancers who applied.
4. Select a freelancer who best meets your needs and budget.
5. Collaborate with the freelancer to finalize your PCB design and manufacturing requirements.
6. Review and approve the final design and proceed with payment.

Using a freelance platform can be particularly helpful if you lack PCB design experience or need assistance with a complex project. However, be sure to thoroughly vet any freelancer before hiring them and establish clear communication and expectations throughout the project.

Method 5: Local PCB Manufacturers

While online ordering has become increasingly popular, local PCB manufacturers can still be a viable option, particularly for complex projects or when you need face-to-face support. To find local PCB manufacturers, try the following:

• Search online directories like Google Maps, Yelp, or Yellow Pages.
• Attend local trade shows or maker faires to meet PCB manufacturers in person.
• Ask for recommendations from colleagues, friends, or online communities.

When working with a local PCB manufacturer, you’ll typically need to provide your PCB design files and discuss your project requirements in detail. Local manufacturers may offer more personalized support and faster turnaround times, especially for prototypes or small batch orders.

However, local manufacturers may have higher prices and limited capabilities compared to online manufacturers, so it’s essential to carefully evaluate your options before deciding.
