This makes it ideal for control systems, embedded systems, robotics, and similar time-sensitive systems.
Ruggedized
The design and construction of components to withstand harsh operating environments and conditions. This can include protection against shock, vibration, temperature changes, and exposure to moisture, dust, and other environmental factors. Ruggedized devices are built to maintain their performance and function in challenging conditions, making them suitable for military, industrial, and outdoor use.
Shielding
Shielding is the process of reflecting electromagnetic radiation. The purpose is to protect components and wiring from outside interference and reduce any signal radiating outward from the cable or device.
Signal integrity
Signal integrity (SI) is a set of measures that quantify the quality of an electrical signal over long distances, through multiple devices, and under various conditions. Key aspects of signal integrity include transmission speed, ringing, crosstalk, distortion, power supply noise, and signal loss.
Smart Factory
An advanced manufacturing facility that uses a range of digital technologies, such as the Internet of Things (IoT), artificial intelligence (AI), and machine learning, to optimize the production process and improve efficiency, productivity, and quality. A Smart Factory aims to create a more agile and flexible production process that can adapt to changing market conditions and customer demands in real time while reducing waste, improving resource utilization, and increasing sustainability.
SMT – Surface Mount Technology
A method of attaching electronic components onto a printed circuit board's surface instead of through holes, resulting in compact, high-density circuits with improved electrical performance, reduced size and weight, and increased production efficiency.
Software engineering
Designing, developing, and maintaining software systems that support and optimize manufacturing processes. It applies engineering principles and methodologies to create reliable, scalable, and efficient software solutions that enhance operational efficiency and enable automation within the manufacturing environment.
Solder Paste Inspection
A process utilizing high-resolution cameras and image processing algorithms to analyze the volume, shape, and alignment of solder paste deposits to verify the accuracy and consistency of these deposits on printed circuit boards (PCBs) before reflow soldering.
Solderability Test
Solderability testing is a destructive test used to verify that the solder adheres to the leads adequately. Two typical testing methods are “dip and look” and Surface Mount Process Simulation.
Source Controlled
When the customer or some situational incident dictates the specific use of a component or commodity source due to contractual arrangements, tooling considerations, security classification requirements, or other controlling circumstances.
Supply Chain Evaluation
A comprehensive assessment of a company's entire supply chain network, from raw material sourcing to product delivery, and includes analyzing efficiency, risks, and costs and identifying opportunities for improvement. The evaluation process considers factors such as supplier performance, logistics, inventory management, and sustainability, resulting in an optimized supply chain that improves a company's competitiveness, costs, and overall performance.
Supply Chain Evaluation
A systematic assessment and analysis within a supply chain to gauge its efficiency, effectiveness, and overall performance, involving evaluating supplier capabilities, quality control measures, lead times, logistics, cost structures, and overall supply chain resilience. Through this comprehensive evaluation, businesses gain insights to identify areas for improvement, optimize processes, mitigate risks, and enhance collaboration with suppliers.
Supply Chain Management
A supply chain is the network of all the people, organizations, resources, activities, and technology involved in producing and selling a product. A supply chain includes everything from source materials to the manufacturer through end-user delivery.
Supply Chain Risk Management
Supply Chain Risk Management involves implementing best practices to mitigate risks and disruptions in the supply chain, including creating strategic partnerships with suppliers, accurate demand planning, leveling demand fluctuations, understanding product lifecycles, and establishing long-term commitments. By adopting these practices, businesses can achieve improved inventory availability, supplier performance, production planning, cost planning, and revenue actualization.
Surface Mount Process Simulation Solderability Test
Surface mount simulation testing is carried out by screen printing a specific solder paste onto a ceramic plate and then placing the component on top of it, after which you apply a specified convection reflow profile.
System Validation Report
This report confirms that all activities specified in the validation plan have been marked as completed. It summarizes the testing results and provides confirmation that all acceptance criteria have been met and the product is ready for deployment.
Through Hole Auto Insertion (Axial, Radial, DIP)
An automated manufacturing process to attach electrical components to printed circuit boards (PCBs). This process is used for components such as axial resistors, radial capacitors, and dual in-line package (DIP) ICs. Through hole auto insertion offers precise component placement and soldering, ensuring secure and reliable connections between components and PCBs, enhancing manufacturing efficiency, reducing assembly time, and maintaining high-quality standards in electronic products manufacturing.
Tombstoning
Tombstoning is a surface mount passive component, such as a resistor or capacitor, that lifts from one pad on one end in the case of a PCB design.
Trace routing
Designing the layout of a PCB’s wiring structure, which defines the copper paths and vias on a PCB.
Transmission
The action or process of passing on a property, including electrical currents or data signals, or the condition of being transmitted.
Upper Level Assemblies
A combination of board-level and system-level assemblies. A higher level bill of materials structure consisting of components and sub-assemblies.
Vertical Manufacturing
Vertical manufacturing refers to the integration of a value chain by a producer in order to gain a strategic advantage. Vertical integration is achieved when manufacturers have control or ownership over aspects of a value chain that are beyond the main manufacturing component.
Vertically Integrated
The practice of a company extending its operations throughout its supply chain. A vertically integrated firm will bring previously outsourced activities back in-house. The vertical integration process may be either upstream (backward) or downstream (forward).
Vias
A via is a copper connection between printed circuit board layers. A via is a tiny drilled hole that passes through two or more adjacent layers, which is plated with copper to create an electrical link between the copper sheets.
Wire and Cable Harnesses
An arrangement of wires and cables, usually with many breakouts, which have been tied together or pulled into a rubber or plastic sheath, used to interconnect an electrical system.
