Conformal Coating for Electronics Protection

The Fill Factor (FF) is a key parameter that determines the quality of a solar cell. It is the ratio of the maximum power a cell can produce ([latex]P_{max}[/latex]) to the theoretical power if it were an ideal voltage and current source ([latex]V_{oc} \times I_{sc}[/latex]). A higher fill factor indicates lower parasitic resistance losses and a more 'square' I-V curve.

The Toyota Production System is founded on the complete elimination of waste, categorized into 7 types, 3 main being described here: Muda (non-value-adding work), Muri (overburden), and Mura (unevenness). While Muda is the most commonly discussed, TPS recognizes that Muri and Mura are often the root causes of Muda and must be addressed first to achieve a truly lean system.

Good Manufacturing Practice (GMP) is a system of regulations and guidelines ensuring that pharmaceutical products are consistently produced and controlled according to quality standards. It covers all aspects of production, from the starting materials, premises, and equipment to the training and personal hygiene of staff. GMP is designed to minimize the risks involved in any pharmaceutical production.

The use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software allows product designers and engineers to create precise 2D and 3D models, replacing manual drafting. This technology dramatically increases productivity, improves the quality of design, and facilitates better communication through detailed visualizations and simulations.

Solid modeling in CAD represents objects as unambiguous, voluminous 3D shapes. Two primary techniques dominate: Boundary Representation (B-rep), which defines a solid by its bounding surfaces (faces, edges, vertices), and Constructive Solid Geometry (CSG), which builds complex shapes by applying Boolean operations (union, subtract, intersect) to simpler primitive solids like cubes, spheres, and cylinders.

A design methodology where 'X' represents a specific product life cycle objective. DFX encompasses a collection of guidelines and techniques aimed at optimizing a product's design for a particular goal, such as manufacturability (DFM), assembly (DFA), reliability (DFR), or sustainability (DfS). This proactive approach addresses potential issues early in the design phase, reducing costs and improving quality.

A structured methodology for creating new products, typically involving analysis, concept development, and synthesis. It is an iterative cycle where designers research user needs, brainstorm ideas, create prototypes, and test them to refine the final product. This process ensures that the end product is both functional and meets market demands effectively before full-scale production.

Heijunka is the principle of production leveling or smoothing within the Toyota Production System. It involves averaging out the production volume and mix over a fixed period to eliminate peaks and valleys in workload. This creates a predictable and stable manufacturing environment, which is a prerequisite for implementing Just-in-Time (JIT) and standardized work effectively.

Takt time is a theoretical calculation representing the pace of customer demand ([latex]Available Time \div Demand[/latex]). In contrast, cycle time is an empirical measurement of the actual time taken to complete one unit of work at a specific process step. A core principle of lean manufacturing is to ensure that cycle time is consistently less than or equal to Takt time.

Chemical Vapor Deposition (CVD) is a coating process where a substrate is exposed to one or more volatile chemical precursors. These precursors react or decompose on the substrate's surface in a reaction chamber, producing a high-purity, high-performance solid thin film or coating. Temperature and pressure are critical process parameters that control the deposition rate and film quality.

FTA is a top-down, deductive failure analysis technique. It starts with a potential undesired event (the "top event") and uses Boolean logic gates (AND, OR, etc.) to determine the combinations of component failures or human errors that could cause it. It provides a graphical model for understanding and quantifying system risk, identifying critical failure paths.

Passive solar design is a building design strategy that uses a building's components—walls, floors, windows, and orientation—to collect, store, reflect, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. Unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.

The Buying Center is a model representing all individuals and groups within an organization who participate in a purchase decision. It's not a fixed unit but a set of roles assumed by different people for different purchases. These roles include initiators, users, influencers, deciders, approvers, buyers, and gatekeepers, each impacting the final decision through their specific function and authority.

Total Quality Management (TQM) is a management philosophy where all members of an organization participate in improving processes, products, services, and the culture in which they work. It aims for long-term success through customer satisfaction. TQM integrates quality-discipline into the culture and activities of a company, moving beyond simple product inspection to a holistic, organization-wide approach.
