PCBflow: Revolutionizing PCB Design and Manufacturing with Cloud-Based Technology

Steph Chavez, Siemens EDA

The electronics industry is constantly evolving, and the need for faster, more efficient, and accurate PCB design and manufacturing has never been greater. Traditional PCB design processes can be cumbersome, requiring multiple iterations, back-and-forth communication between designers and manufacturers, and often lead to costly errors.

In the PCB design and manufacturing process, here are three major stumbling blocks that can hinder project completion:

1. Technical Queries (TQs) – TQs arise when manufacturers encounter significant issues in the design package that prevent them from proceeding with fabrication. This causes delays, requiring the design team to address problems urgently. It leads to increased costs and schedule delays as the team must resolve these issues before production can continue.

You probably dread hearing (or seeing) the words: Technical Queries (TQs). This often means that your design package (data content) needs to be addressed ASAP before proceeding with fabrication. In many cases, this usually results in loss of time in the project schedule and increased engineering cost to address these TQs (issues).

• Communication Gaps between Designers and Manufacturers – Traditional PCB design processes often suffer from poor communication between designers and manufacturers, which leads to errors and inefficiencies. Misalignment between design expectations and manufacturing capabilities can result in costly rework, delays, and compromised designs.

• Manufacturability Issues – Failing to optimize PCB designs for manufacturability before sending them for production is a common stumbling block. Without proper validation, designs may not meet the specific requirements of manufacturers, leading to fabrication errors, wasted materials, and additional costs.

Enter PCBflow—a cloud-based platform that aims to revolutionize the way PCBs are designed and manufactured. It’s a game changer for PCB designers and manufacturers alike. PCBflow helps overcome these challenges by offering cloud-based real-time feedback, manufacturability checks, and improved collaboration between designers and manufacturers.

What is PCBflow?

PCBflow is a cloud-based platform developed by Siemens Digital Industries Software that facilitates collaboration between PCB designers and manufacturers. It is indorsed by IPC, which is the industry trade association that sets all industry standards for electronic systems design, fabrication, and assembly. PCBflow enables designers to seamlessly validate their PCB designs using real-time manufacturability feedback, ensuring that the designs are optimized for production before they reach the fabrication stage. This Design for Manufacturability (DFM) validation helps identify potential issues early in the design process, reducing errors, speeding up time to market, and lowering production costs.

By leveraging the cloud, PCBflow offers a streamlined approach to PCB design, allowing users to access the platform from anywhere, collaborate with manufacturers in real time, and benefit from automated design checks.

Key Features of PCBflow

1. Cloud-Based DFM Validation – PCBflow offers real-time DFM validation in the cloud, allowing PCB designers to upload their designs and receive immediate feedback on potential manufacturing issues. This feedback is tailored to the specific capabilities and constraints of the manufacturer, ensuring that the design is fully optimized for production.

By catching potential problems early, designers can make adjustments before sending the design to production, significantly reducing the risk of delays and costly rework.

• Instant Feedback from Manufacturers – One of PCBflow’s standout features is its ability to provide instant feedback from manufacturers. PCB manufacturers can upload their process capabilities, allowing designers to validate their designs against the specific manufacturing requirements. This ensures that designs meet all necessary criteria, such as trace widths, spacing, hole sizes, and more.

This manufacturer-specific feedback is crucial because different manufacturers have different capabilities and limitations. PCBflow ensures that designs are perfectly tailored to the chosen manufacturer’s specifications, improving the chances of first-pass success.

• Design Rule Checks (DRC) – PCBflow performs automated Design Rule Checks (DRC) that analyze the PCB design against predefined rules for manufacturing. These checks include verifying that the design adheres to industry standards as well as the manufacturer’s specific constraints, reducing the risk of fabrication errors.

• Collaborative Platform – PCBflow allows for seamless collaboration between designers and manufacturers. By enabling real-time communication, the platform fosters a closer working relationship, where both parties can work together to optimize the design for manufacturability. This is especially important when dealing with complex designs or specific manufacturing requirements.

• Security and Data Protection – PCBflow ensures that sensitive design data is protected through secure cloud technology. Designers can confidently share their design files knowing that their intellectual property is safe and secure. The platform follows industry-standard security protocols to protect data from unauthorized access or leaks.

Benefits of PCBflow

1. Same benefits of ValorNPI – PCBflow is powered by ValorNPI, the leading industry DFM provider. Easily upload and preview your designs in a wide range of formats, including ODB++, IPC2581, Gerber 274x and other common EDA formats.

• Instant access to participating manufacturing DFM rule-sets – DFM profiles span the electronics landscape, addressing design rules for everything from off-the-shelf electronics to human-life-critical electronics, from easy-to-produce printed circuit boards to high-density circuits.

For Assembly DFM, we merge accurate part geometry provided by Valor Parts Library into your design, to provide comprehensive placement and solderability analysis.

• No need to absorb full expense of tool to use – Pay as you go or purchase a specific set of analysis’ reports according to your company’s project expectations and or anticipated forecasting.

• Cloude based – No need for local install and to maintain. A web-based platform that lets you quickly implement IPC DFM in your designs. Set up a company account and connect with IPC and participating manufactures in the PCBflow network.

• IPC Standards Alignment – Extracted design requirements from IPC standards and combined with industry research and established a generic ruleset for DFM: profiles have been created according to Performance Classes 1, 2, and 3 (IPC-A-610) and Producibility Levels A, B, and C (IPC-2221).

PCBflow in Action: How it Works

1. Upload the Design – Designers can upload their PCB design files (such as Gerber files or ODB++ format) to the PCBflow platform. The platform supports a wide range of design formats used in the PCB industry.

• Select a Manufacturer – PCBflow allows users to choose from a network of manufacturers who have provided their process capabilities. Designers can select a manufacturer based on their specific requirements or preferences.

• Run DFM Analysis – Once the design is uploaded, PCBflow runs a comprehensive DFM analysis based on the selected manufacturer’s capabilities. This analysis checks the design for potential issues such as trace widths, spacing, hole sizes, via placements, and more.

• Receive Feedback: The platform provides real-time feedback on any issues found during the DFM analysis. Designers can review the feedback, make necessary adjustments to the design, and resubmit the design for further analysis.

• Optimize and Finalize – Once the design has passed all manufacturability checks, it is optimized and ready to be sent to the manufacturer for production.
