5 Principles of Design for Electronic Manufacturing Which Lead to 10 Levels of Savings

Many electronic products perform well during development but become expensive or difficult to manufacture once production begins. This article is written for engineers, OEMs, and product development teams evaluating design for manufacturing (DFM) as part of their product development process. The perspective reflects Levison Enterprises’ experience helping customers optimize electronic designs to reduce production costs, improve manufacturability, and support a smoother transition from prototype to full-scale manufacturing.

Bringing a new electronic product to market is exciting. It’s also where many companies unknowingly create costly problems.

A design may look great on paper and meet all performance requirements during development. But once production begins, unexpected challenges can emerge. Components may be difficult to source. Electronic assembly may require excessive labor. Testing may reveal reliability issues. Compliance requirements may be overlooked. Every one of these problems adds cost, can delay production, and impact profitability.

The good news is many manufacturing challenges can be prevented with design for manufacturing (DFM) long before the first product run.

What Is Design for Manufacturing?

Design for manufacturing is a structured process used to evaluate a product design before production begins. The goal is simple: create a product that performs as intended while being efficient, reliable, cost-effective, and practical to manufacture at scale.

Rather than waiting until production uncovers problems, DFM identifies opportunities for improvement during the design phase, when changes are significantly less expensive to make.

For electronic manufacturers, DFM involves collaboration between engineering, manufacturing, sourcing, quality, and compliance teams. Together, we review the design from every angle to uncover risks, eliminate inefficiencies, and improve manufacturability.

The result is a product that is easier to build, easier to scale, and less expensive to produce.

Why DFM Matters

The cost of fixing a design issue increases dramatically as a product moves through development. A change made during design may take only hours to implement. The same change discovered after production begins can require redesigns and additional testing.

DFM can help you avoid these costly setbacks by answering important questions early:

• Can this product be assembled efficiently?
• Are the materials appropriate for the application?
• Will the design perform reliably in its operating environment?
• Are there unnecessary costs built into the product?
• Does the design meet all applicable industry standards and regulations?

Addressing these questions upfront helps teams launch products faster while reducing risk throughout the product lifecycle.

The Five Areas Evaluated During DFM

Manufacturing Process

The most effective manufacturing process is not always the most complex one.

During a DFM review, engineers evaluate available manufacturing methods to determine which approach delivers the required quality at the lowest cost. Production volume, assembly requirements, materials, testing needs, and future scalability all factor into this decision.

Selecting the right process early can significantly reduce labor costs, production time, and unnecessary complexity.

Product Design

A design that functions well isn’t necessarily easy to manufacture.

DFM looks at drawings, tolerances, component placement, assembly requirements, and production workflows to identify opportunities for simplification. Even small adjustments can improve assembly speed, reduce defects, and increase overall reliability.

The goal is to create a design that works well in theory and on the production floor.

Material Selection

Choosing materials is often a balancing act between performance and cost.

Many products are initially designed with materials that exceed actual requirements, adding unnecessary expense. A DFM review evaluates material strength, thermal performance, electrical characteristics, environmental exposure, and durability to determine whether more cost-effective components can achieve the same results.

The right material should support performance requirements without inflating electronic manufacturing service costs.

Environmental Performance

Products must perform reliably in the conditions where they will be used.

An electronic assembly operating in a climate-controlled office faces very different challenges than equipment exposed to moisture, vibration, dust, extreme temperatures, or outdoor environments.

DFM evaluates these operating conditions to verify that the design, components, and materials can withstand real-world use over the product’s expected lifespan.

Compliance Requirements

Compliance issues discovered late in development can be expensive and time-consuming.

Whether a product needs to meet safety regulations, industry certifications, customer specifications, or quality standards, those requirements can be incorporated into the design from the beginning.

A thorough DFM review helps identify compliance concerns early, reducing the risk of failed testing, redesigns, or delayed product launches.

How DFM Creates Cost Savings

Many companies view DFM as an additional step in product development. In reality, it is often one of the most effective ways to reduce total manufacturing costs.

Here are some of the biggest ways DFM creates savings:

Reduces Part Count

Every component adds material costs, assembly time, inventory management requirements, and potential failure points. Simplifying a design often reduces costs across multiple areas of production.

Minimizes Custom Components

Custom parts frequently increase tooling expenses, lead times, and procurement challenges. Whenever possible, DFM identifies opportunities to use proven standard components that are readily available and cost-effective.

Improves Assembly Efficiency

Products designed for straightforward assembly require less labor and are less prone to manufacturing errors. Faster assembly translates directly into lower production costs.

Eliminates Unnecessary Fasteners

Reducing screws, brackets, adhesives, and other fastening methods can significantly shorten assembly time while simplifying production processes.

Reduces Handling and Rework

Designs that require fewer manual adjustments, repositioning steps, or special handling improve throughput and reduce opportunities for mistakes.

Supports Product Standardization

Using common components and design modules across multiple products can simplify inventory management, reduce procurement costs, and accelerate future product development.

Improves Quality and Reliability

When products are designed with manufacturing realities in mind, they tend to experience fewer defects, less rework, and fewer warranty issues after deployment.

DFM Helps You Build Better Products

The temptation to move quickly from design to production is understandable. However, skipping a thorough design for manufacturing review often results in higher costs, production delays, and avoidable frustrations later in the process.

DFM provides an opportunity to optimize a product before those problems occur. By evaluating manufacturing processes, materials, environmental requirements, design efficiency, and compliance needs, electronic manufacturers can create products that are easier to build, more reliable, and more cost-effective.
