TABLE OF CONTENTS
Before a PCB can move from design to production, electrical engineers are typically tasked with a slew of work: select and qualify components, manage alternates, release an accurate electronic bill of materials (eBOM), prepare fabrication and assembly files, document revisions, and communicate changes to everyone from mechanical engineering to procurement and manufacturing. The design of the board is often the easy part!
All this work extends well beyond the electrical CAD (ECAD) environment and often to a mashup of spreadsheets, shared drives, email threads, and manually copied data. Product lifecycle management (PLM) brings those processes together. It connects component data, PCB releases, approvals, sourcing decisions, and manufacturing documentation so engineers can move a design forward without losing context or control.
Key takeaways
- ECAD is where electrical engineers create schematics and PCB layouts. PLM manages how those designs are released, changed, shared, and incorporated into the complete product record.
- PLM helps teams control eBOMs, component data, approved alternates, board revisions, engineering changes, and manufacturing release packages.
- Connecting ECAD and PLM reduces duplicate data entry and helps keep engineering, sourcing, manufacturing, and other stakeholders aligned.
- Duro’s Altium 365 integration connects electrical design data with the broader product lifecycle, allowing teams to synchronize components and publish project and manufacturing information into PLM.
What is PLM for electrical engineering?
Product lifecycle management (PLM software) the information, decisions, and processes associated with a product from its initial design through production, service, and retirement.
For an electrical engineer, that can include:
- Electronic bills of materials
- Internal and manufacturer part numbers
- Approved manufacturers and alternate components
- Schematics, PCB documentation, and source files
- Gerber, ODB++, NC drill, pick-and-place, and assembly files
- Board and product revisions
- Engineering change requests and change orders
- Release status and approval history
- Sourcing and supplier information
- Documentation shared with procurement and contract manufacturers
ECAD is the design environment that gives engineers the tools to capture schematics, lay out circuit boards, maintain design rules, and generate the outputs required to build the board. Meanwhile PLM governs the broader product record. It connects the released electrical design to the parts, assemblies, approvals, people, and downstream systems involved in delivering the complete product.
An engineer may work primarily in ECAD, but the rest of the company needs access to their work, from procurement to manufacturing to leadership. To facilitate this, PLM creates a shared, controlled source for that information without requiring every stakeholder to work inside the electrical design tool.
Why electrical engineering teams need PLM
Most engineering teams need PLM, and electrical engineers are no different. As an example, both electrical and mechanical engineering teams need revision control, structured product data, formal releases, traceable changes, and coordination with other teams. The difference lies in the details of the engineering information being managed.
Electrical teams face their own version of the product data problem: component libraries containing thousands of records, fast-changing availability and lifecycle statuses, design outputs that must remain synchronized, and assemblies in which a seemingly small substitution can create electrical, mechanical, firmware, compliance, or manufacturing consequences.
Component data is constantly changing
Say a capacitor that was available during prototyping becomes constrained, obsolete, or too expensive before production begins. A new part may look equivalent on paper but differs in footprint, temperature rating, tolerance, firmware requirements, or compliance status. How are you tracking these types of changes?
Teams need more than a list of manufacturer part numbers. They need a controlled record of which components are approved, which alternatives can be used, where each part appears, and what review was completed before a substitution was accepted.
Without that record, engineers can end up repeating qualification work, leading to wasted time and higher costs. A PLM platform’s major ROI comes directly from eliminating this type of rework.
A PCB release is a coordinated package of data
A board cannot be manufactured from a schematic alone. The contract manufacturer will also require fabrication files, assembly drawings, test documentation, and an accurate BOM. And of course, all of those outputs must correspond to the same approved revision. If the BOM comes from one revision and the Gerber files come from another, the build is already in trouble.
PLM gives teams a way to publish and control the complete release package rather than asking downstream partners to cobble it together from individual files and messages.
Electrical changes affect the rest of the product
Electrical engineering never happens in isolation. Changing a connector can affect an enclosure opening or cable assembly. Replacing a power component may change the product’s thermal behavior. A PCB revision may require new firmware.
A PLM workflow makes those relationships visible. It gives the affected teams an opportunity to review the change before it reaches production and preserves the reasoning behind the final decision.
Manual handoffs create avoidable risk
Exporting an eBOM to a spreadsheet and then re-entering its data in another system may work for an early prototype, but this workflow typically leads to compounding errors as the product grows, the number of boards increases, and the team moves through repeated revisions.
Manual handoffs introduce opportunities for incorrect quantities, mismatched part numbers, missing alternates, outdated files, and simple copying errors. They also consume engineering time without improving the design. Connecting ECAD and PLM reduces this manual administrative work while giving other teams faster access to accurate information.
How PLM improves electrical engineering workflows
PLM gives teams a reliable process for moving electrical product data from design through approval and into production.
Build a controlled electronic BOM
The eBOM is one of the most important links between electrical design and the rest of the company. In a PLM system, the eBOM becomes a structured, revision-controlled product record rather than a static spreadsheet export. Component records can include descriptions, manufacturer part numbers, approved part choices, sourcing information, lifecycle data, and supporting documentation. The team can always see which revision is current and trace how the BOM has changed over time.
For example, let’s say you have a control board that uses a voltage regulator selected during prototyping. If the regulator must be replaced before production, PLM can connect the proposed substitute to the affected board, document the reason for the change, route it for review, and preserve the approved result as part of the next revision.
Centralize component and part-choice information
Electrical teams often accumulate component data in several places: an ECAD library, sourcing spreadsheets, distributor websites, ERP records, and often simply inside the brains of individual engineers. When those sources disagree, it becomes difficult to know which record is authoritative.
PLM centralizes the product context around each component. Engineers and sourcing teams can work from the same internal part number, manufacturer information, approved alternatives, and usage history. Before adding another connector or capacitor to the library, an engineer can determine whether the company has already qualified a suitable part. This improves design reuse and reduces unnecessary component proliferation.
Control PCB revisions and engineering changes
Suppose a key component reaches end-of-life. The team can identify the affected assemblies, propose a replacement, evaluate electrical and cross-functional impacts, and document the decision through an engineering change order. When the change is approved, the updated eBOM, PCB documentation, and manufacturing outputs can be released together.
A modern PLM system provides a consistent path from a proposed change to an approved release, with the affected data and reviewers attached to the decision. The result is a clear history of what changed, why it changed, who reviewed it, and which revision entered production. That traceability becomes especially valuable when a field issue appears months later or a team needs to understand why a previous design decision was made.
Respond faster to shortages and obsolescence
When a component becomes unavailable, the first questions are usually where it is used, whether an alternative has been approved, what products are affected, and which teams need to review a change. A connected product record in your PLM makes those answers easier to find. Engineering can evaluate the replacement with the relevant context, while sourcing, manufacturing, quality, and other stakeholders follow the same controlled process.
Connecting Altium 365 and Duro PLM
Duro’s Altium 365 integration connects ECAD data with PLM so teams can synchronize components and project information, automatically generate a structured eBOM in Duro, transfer manufacturing documentation, and support releases and change orders.
From Altium Design to a controlled product record
An electrical engineer can design the board in Altium Designer and manage the project through Altium 365, then sync component and project information with Duro. When the project is ready for release, the eBOM and associated production documentation can be published into PLM for review and use by the rest of the organization.
This creates a clean division of work. Engineers continue designing in the ECAD environment built for that purpose. Duro manages the product structure, release status, change history, and cross-functional access surrounding the design. Mechanical engineering and other reviewers gain visibility into the released product data without requiring access to the engineer’s working environment.
Less copying and fewer disconnected records
Without an integration, component and project information must often be entered in both ECAD and PLM. In addition to taking time, duplicate entry creates the possibility that the records will diverge.
The Altium 365 and Duro integration supports bidirectional synchronization of component information, helping teams maintain consistent part records across both systems without having to duplicate entries in both platforms.
Duro’s detailed guide to the Altium 365 and Duro PLM integration explains the synchronization and release workflow in greater depth.
Give electrical engineers more time to actually engineer
Electrical engineers should spend their time engineering instead of spending hours reconciling spreadsheets, copying component data, or determining which manufacturing file matches the latest BOM.
A robust PLM like Duro provides the structure around the design work. It turns eBOMs into controlled product records, connects component decisions to the assemblies they affect, coordinates engineering changes, and gives downstream teams a reliable release package.
For teams using Altium, Duro extends that workflow through a direct Altium 365 integration. Electrical engineers can continue working in their ECAD environment while Duro connects their designs to sourcing, approvals, manufacturing, and the rest of the hardware lifecycle.
