**1. What is the process? What are the research fields of electronic technology?**
A: The process refers to the set of procedures, methods, and techniques used by manufacturers to transform raw materials and semi-finished products into finished goods that meet technical specifications. It represents the accumulated knowledge and operational experience of human labor in production.
In the context of electronic product manufacturing, the process involves two main aspects: the technical methods and skills used in production, and the quality control and management throughout the process. These can be thought of as the "hardware" and "software" of the system. Research in this area focuses on materials, equipment, methods, and operators—commonly referred to as the "4M + M" model.
**2. What are the characteristics of electronic technology?**
A: As a discipline closely tied to real-world applications, electronic technology has distinct features. Key points include:
1) **Interdisciplinary nature**: Electronic technology intersects with many scientific fields such as physics, chemistry, electrical engineering, mechanical engineering, materials science, computer science, and more. It also includes business-related disciplines like operations research and systems engineering. This makes it a highly comprehensive field.
2) **Rapid development**: Although widely applied, electronic technology was only formally studied as a subject in the 1970s. Since then, it has evolved quickly, with new methods and materials constantly emerging. This rapid pace means that processes often become outdated before they are fully adopted.
Today, key technologies are protected through patents, and companies often keep them confidential. This makes it challenging to access and collect critical process knowledge.
**3. What is the goal of electronic technology training?**
A: The aim of training is to equip students with the skills and knowledge needed to manage and guide the production of electronic products. They should be able to solve practical problems and understand modern production technologies and equipment. Training also emphasizes the importance of process work and prepares students for high-level roles in the industry.
**4. What is the scope of work for electronic process technicians?**
A: Electronic process technicians are responsible for preparing production plans, writing work instructions, managing quality control, and solving on-site issues. They also design testing tools, review new product designs, and coordinate between departments to ensure smooth production and high-quality output.
**5. How are electronic components classified? What are their main requirements?**
A: Electronic components have evolved through three generations: vacuum tubes, transistors, and integrated circuits. Their main requirements include high reliability, precision, small size, stable performance, and environmental compliance.
**6. What are the main parameters of electronic components?**
A: Parameters include characteristic parameters (describing function), specification parameters (such as nominal values and tolerances), and quality parameters (measuring stability under different conditions).
**7. Does a linear component always have a straight-line V-I curve?**
A: No. A linear component is defined by its constant characteristic parameter under certain conditions, not necessarily by a straight line on a voltage-current graph.
**8. What are the specifications of electronic components?**
A: Specifications include nominal value, allowable deviation, rated value, and limit values, among others.
**9. What is a nominal value series? For example.**
A: Nominal values are standardized to facilitate mass production. For resistors, common series include E24, E12, and E6, each with specific tolerances and values.
**10. What is the difference between allowable deviation, two-way deviation, and one-way deviation?**
A: Allowable deviation refers to the acceptable range of variation from the nominal value. Two-way deviation allows for variation in both directions, while one-way deviation restricts it to one side.
**11. What is the rated value? When should derating be considered?**
A: Rated values define the maximum safe operating limits of a component. Derating is necessary when working conditions exceed these limits to prevent failure.
**12. What are the main quality parameters of electronic components?**
A: Quality parameters include temperature coefficient, noise level, high-frequency performance, reliability, and solderability. These determine how well a component performs under varying conditions.

A concave grating has the advantage of setting up a spectroscopic system without any imaging optics like concave mirrors. For this reason, the concave grating is used in a wide range of applications, such as analytical instruments, optical communications, biotechnology, and medical instruments. Spectroscopes incorporating concave gratings are classified roughly into two categories: polychromators or monochromators. holographic concave gratings are recorded on spherical substrates, with equidistant and parallel grooves.
