Electromechanical Assembly From Design to Assembly

Building a fully functional electro-mechanical device involves a highly complex process, from initial concept and design to component sourcing, PCB and electronic assembly, and final testing and inspections. Omini leverages advanced equipment and an experienced team to successfully complete each step of this intricate task, ensuring a high-quality, fully functional final product.

1. Design Process
The design phase of electro-mechanical products follows established industry standards regarding tolerances and design rules. Omini ensures that the optimal design satisfies functional requirements while balancing cost and quality. Computer-aided design (CAD) systems are employed to simulate 3D models of the design, incorporating geometry, tolerancing, and providing graphical and statistical displays. This process enables efficient, automated configuration in robotic cells, ensuring precision throughout assembly.

2. Sourcing of Parts
Sourcing the right materials for electro-mechanical products is a crucial step in the assembly process. Omini carefully selects parts based on their lead times and visual inspections to meet dimensional requirements. Thorough quality checks are conducted early in the sourcing phase to identify any potential issues before the assembly process begins. The materials are chosen for their availability from multiple vendors, ensuring flexibility and cost-effectiveness in the procurement process.

3. Assembly of Electrical and Mechanical Parts
Once the parts are sourced, the next step is integrating the electrical and mechanical components. Omini specializes in PCB assembly using Surface Mount Technology (SMT), where electrical components are mounted onto the printed circuit board through soldering and reflow processes. The assembled PCBs undergo rigorous testing before being integrated into the final electro-mechanical product. While automation is typically used for high-volume, low-mix production, Omini also excels in manual assembly for low-volume, high-mix projects, offering flexibility and efficiency in meeting customer needs.

4. Inspection and Testing
Quality control is a vital aspect of the electro-mechanical assembly process. Omini employs a combination of hands-free, automatic, and manual inspection methods to ensure each component meets stringent quality standards. Automated inspection systems use image-based measurement systems and visual algorithms to compare parts against reference images and specifications. If a part falls outside the acceptable limits, it is immediately rejected. This efficient process, coupled with human oversight, ensures that every part and product meets the highest standards of performance and reliability.

By carefully managing every stage from design to assembly, Omini delivers electro-mechanical assemblies that meet industry standards, ensuring a reliable, functional end product that satisfies customer requirements.

Design Considerations in Electro-Mechanical Assemblies

Electro-mechanical assembly is a highly intricate process that requires careful planning and execution to avoid issues during and after production. At Omini, we ensure that all key factors are considered at the design stage to deliver seamless electro-mechanical assemblies. Below are the critical design considerations that an electro-mechanical assembly company should prioritize:

1. Requirements Definition
The development process for any electro-mechanical product begins with a comprehensive set of requirements, typically derived from the customer. The goal of this stage is to create a clear project management plan, schedule, and technical review framework. These documents will outline product specifications and functionality. At Omini, we emphasize the importance of well-defined requirements, which enable us to design and build a product that meets all functional, quality, and reliability standards. While these specifications may evolve during the design validation phase, it’s crucial to understand the product’s function from the outset to ensure success.

2. Material Selection
Choosing the right materials is a pivotal part of designing electro-mechanical devices. Material selection should be driven by application-specific needs, considering factors like corrosion resistance, cost, machining properties, and availability. At Omini, we ensure that materials used in our assemblies meet strict regulatory standards like RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals). Additionally, for components like solenoids and automotive brakes, electromagnetic properties must also be carefully considered.

3. Thermal Considerations
The thermal performance of each component plays a significant role in electro-mechanical assemblies. Factors like thermal conductivity, heat capacity, and material density must be considered during the design process. At Omini, we use advanced tools like Finite Element Analysis (FEA) to simulate thermal behavior and stress effects. Addressing thermal expansion differences during assembly helps prevent issues like delamination, warping, and other failure modes that could impact long-term performance.

4. Manufacturability
An effective electro-mechanical design balances performance with cost considerations. This is achieved through Design for Manufacturability (DFM), a process that integrates best practices and design rules to ensure that the product can be efficiently produced and assembled. At Omini, we emphasize the importance of classifying design requirements into “need-to-have” and “nice-to-have” categories. The latter addresses secondary considerations, while the former focuses on the critical aspects required for the product’s functionality. DFM principles guide engineers to optimize design for ease of manufacturing, ensuring timely and cost-effective production without compromising product performance.

At Omini, we take a meticulous approach to electro-mechanical assembly design, ensuring that each product is not only functional but also manufacturable, cost-effective, and compliant with industry standards.
