Assembly

Precision Mechanical & Electromechanical Assembly Solutions

At Secondary Solutions Inc. (SSI), we provide contract assembly services that help manufacturers simplify production, reduce supplier management, and improve overall product quality.

Since 1996, OEMs and contract manufacturers have relied on SSI to assemble products ranging from simple subassemblies to highly complex electromechanical systems requiring extensive documentation, quality control, and process discipline.

Whether your project consists of a few components or hundreds of individual parts, SSI develops repeatable assembly processes that deliver consistent quality from prototype through full production.

From Simple Assemblies to Complex Manufacturing

Every product presents unique assembly challenges.

Over the years, SSI has supported projects ranging from straightforward mechanical assemblies to highly sophisticated medical devices involving:

• More than 1,200 documented assembly operations
• Over 480 individual components
• Multiple inspection points
• Functional verification
• Detailed work instructions
• Controlled manufacturing documentation
• Repeatable production processes

Experience with assemblies of this complexity has shaped the disciplined manufacturing approach we apply to every project, regardless of size.

Our Assembly Capabilities

SSI supports a wide variety of assembly operations, including:

• Mechanical assembly
• Electromechanical assembly
• Plastic component assembly
• Medical device assembly
• Electronic subassemblies
• Hardware installation
• Fastener installation
• Label application
• Functional accessories
• Final product assembly

Whether assembling ten parts or hundreds of components, our focus remains the same—accuracy, consistency, and repeatability.

Controlled Assembly Processes

Successful assembly depends on standardized processes.

SSI develops controlled manufacturing procedures that may include:

• Detailed work instructions
• Assembly sequencing
• Torque specifications
• Material verification
• Lot traceability
• In-process inspections
• Final inspection
• Functional verification
• Customer-specific documentation

Our structured approach helps minimize variation while improving production consistency.

Operator-Controlled Manufacturing

Many assembly operations require skilled technicians rather than fully automated production lines.

SSI's experienced operators work with precision tools, fixtures, and documented procedures to ensure every component is assembled correctly and consistently.

This approach provides excellent flexibility for:

• Prototype projects
• Engineering changes
• High-mix manufacturing
• Low-to-medium production volumes
• Medical products
• Industrial equipment
• Complex assemblies

Our experienced technicians can adapt quickly while maintaining the quality standards our customers expect.

Inventory & Material Management

Successful assembly begins long before production starts.

SSI works with customers to help manage:

• Customer-supplied materials
• Purchased components
• Hardware
• Labels
• Packaging
• Lot traceability
• Production scheduling
• Material verification

Effective material management helps reduce delays while improving production efficiency.

Quality Assurance

Quality is built into every assembly process.

SSI incorporates quality verification throughout production, including:

• Material verification
• In-process inspections
• Visual inspection
• Functional verification
• Documentation review
• Customer-specific quality requirements
• Final inspection

Every assembly process is designed to produce consistent, repeatable results.

Integrated Secondary Manufacturing

Many customers combine assembly with SSI's complete range of secondary manufacturing services, including:

• Ultrasonic welding
• Spin welding
• Heat staking
• Adhesive bonding
• UV adhesive application
• Pad printing
• Hot stamping
• Plastic painting
• Conformal coating
• Potting & encapsulation
• EMI/RFI shielding
• Inspection & packaging

Consolidating multiple manufacturing operations with a single supplier simplifies production while reducing transportation, lead times, and administrative costs.

Why Manufacturers Choose SSI

Manufacturers choose SSI because successful assembly requires more than putting parts together—it requires organization, documentation, process control, and attention to detail.

Whether your project consists of a simple mechanical assembly or a highly complex electromechanical product, SSI provides the manufacturing discipline needed to produce consistent, high-quality assemblies.

Customers benefit from:

• Manufacturing experience since 1996
• Complex assembly expertise
• Prototype through production support
• Experienced assembly technicians
• Controlled manufacturing documentation
• Flexible production volumes
• Responsive customer service
• Competitive pricing
• Minnesota-based manufacturing
• Consistent manufacturing quality

Production Experience

SSI has assembled products ranging from simple subassemblies to complex electromechanical systems with over 1,200 documented operations and more than 480 individual components. Since we began tracking, our team has installed over one million brass inserts. These figures are only what we have recorded since we started keeping track; actual production totals are higher.
