    Etching Department in Electronics Factory: Comprehensive Workflow.
    The etching department in an electronics factory plays a crucial role in the production of printed circuit boards (PCBs). Etching is a chemical process that removes unwanted copper from the PCB, leaving behind the desired circuit pattern. The workflow in the etching department involves several key steps:
    1. Panel Preparation: The process begins with the preparation of the PCB panels. The panels are coated with a photoresist, which is a light-sensitive material that will protect the desired copper areas from etching.
    2. Imaging: The photoresist is then exposed to ultraviolet (UV) light through a photomask. The photomask defines the circuit pattern that will be etched. The exposed areas of the photoresist will harden, while the unexposed areas will remain soft.
    3. Development: The exposed photoresist is then removed using a developer solution. This leaves behind the desired circuit pattern on the PCB panel.
    4. Etching: The PCB panel is then immersed in an etching solution, which removes the unprotected copper. The etching solution is usually composed of a strong acid, such as hydrochloric acid or ferric chloride.
    5. Stripping: After etching, the remaining photoresist is removed using a stripping solution. This leaves behind the finished PCB with the desired circuit pattern.
    6. Inspection: The etched PCBs are then inspected to ensure that they meet the specifications. This involves visual inspection as well as electrical testing.
xposed    7. Storage: The finished PCBs are stored in a controlled environment to prevent contamination or damage.

    电子厂蚀刻部详细工作流程。
    电子厂蚀刻部在印刷电路板（PCB）生产中扮演着至关重要的角。蚀刻是一种化学过程，它去除PCB上不需要的铜，留下所需的电路图案。蚀刻部的操作流程包含多个关键步骤：
    1. 面板准备，流程从PCB面板的准备开始。面板涂有一层光刻胶，这是一种感光材料，它能保护所需的铜区域不被蚀刻。
    2. 成像，然后通过光掩模将光刻胶暴露在紫外线（UV）下。光掩模定义了将被蚀刻的电路图案。光刻胶的曝光区域会硬化，而未曝光区域会保持柔软。
    3. 显影，然后使用显影液去除曝光的光刻胶。这会在PCB面板上留下所需的电路图案。
    4. 蚀刻，然后将PCB面板浸入蚀刻液中，去除未受保护的铜。蚀刻液通常由强酸组成，例如盐酸或三氯化铁。
    5. 剥离，蚀刻后，使用剥离液去除剩余的光刻胶。这会留下具有所需电路图案的成品PCB。
    6. 检测，然后检测蚀刻的PCB，以确保其符合规格。这包括目测检查和电气测试。
    7. 存储，成品PCB被存储在受控的环境中，以防止污染或损坏。
