一.PCB演变1.1 PCB扮演的角色PCB的功能为提供完成第一层级构装的组件与其它必须的电子电路零件接合的基地,以组成一个具特定功能的模块或成品。

所以PCB在整个电子产品中,扮演了整合连结总其成所有功能的角色,也因此时常电子产品功能故障时,最先被质疑往往就是PCB。

图1.1是电子构装层级区分示意。

1.2 PCB的演变1.早于1903年Mr. Albert Hanson首创利用"线路"(Circuit)观念应用于电话交换机系统。

它是用金属箔予以切割成线路导体,将之黏着于石蜡纸上,上面同样贴上一层石蜡纸,成了现今PCB的机构雏型。

见图1.2ﻫ2. 至1936年,Dr Paul Eisner真正发明了PCB的制作技术,也发表多项专利。

而今日之print-etch(photoimage transfer)的技术,就是沿袭其发明而来的。

1.3 PCB种类及制法ﻫ在材料、层次、制程上的多样化以适合不同的电子产品及其特殊需求。

以下就归纳一些通用的区别办法,来简单介绍PCB的分类以及它的制造方法。

1.3.1 PCB种类A. 以材质分a. 有机材质ﻫ酚醛树脂、玻璃纤维/环氧树脂、Polyimide、BT/Epoxy等皆属之。

b. 无机材质铝、Copper-invar-copper、ceramic等皆属之。

主要取其散热功能ﻫ B. 以成品软硬区分a. 硬板 Rigid PCBb.软板 Flexible PCB见图1.3 ﻫc.软硬板 Rigid-Flex PCB 见图1.4ﻫC. 以结构分ﻫa.单面板见图1.5 ﻫb.双面板见图1.6ﻫ c.多层板见图1.7D. 依用途分:通信/耗用性电子/军用/计算机/半导体/电测板…,见图1.8 BGA.另有一种射出成型的立体PCB,因使用少,不在此介绍。

1.3.2制造方法介绍ﻫ A. 减除法,其流程见图1.9B. 加成法,又可分半加成与全加成法,见图1.101.11ﻫ C. 尚有其它因应IC封装的变革延伸而出的一些先进制程,本光盘仅提及但不详加介绍,因有许多尚属机密也不易取得,或者成熟度尚不够。

電路板進化史
PCB(Printed Circuit Board)中文稱為印刷 電路板,也有稱為PWB(Printed Wiring Board)印 刷線路板。它取代1940年代前,電器產品以銅線配 電的方式,使大量生產復制速度加快,產品體積得 以縮小。 早期的電路板是將金屬熔融覆蓋于絕緣板表 面,作出線路。1936年以後轉向將覆蓋有金屬的絕 緣基板以耐蝕油墨作區域選別,將不要的區域蝕刻 去除,叫做“Print & Etch”。 1960年以後,電唱機/錄音機/錄影機等產品 市場,陸續采用了“雙面貫通孔”的電路板制造技 術,于是耐熱及尺寸安定的“環氧樹脂基板”被大 量采用,至今仍為電路板的主要樹脂基材。

pcba工艺流程介绍大纲

pcba工艺流程介绍大纲

pcba工艺流程介绍大纲英文回答:Introduction:PCBA (Printed Circuit Board Assembly) is a crucial process in the manufacturing of electronic devices. It involves the assembly of electronic components onto aprinted circuit board (PCB) to create a functionalelectronic system. The PCBA process consists of several steps, including component placement, soldering, inspection, and testing. In this article, I will provide an outline of the PCBA process.Component Placement:The first step in the PCBA process is component placement. This involves placing electronic components,such as resistors, capacitors, and integrated circuits,onto the PCB according to the design specifications. Thecomponents can be placed manually or by using automated pick-and-place machines. The goal is to ensure the accurate and precise placement of components on the PCB.Soldering:Once the components are placed on the PCB, the next step is soldering. Soldering is the process of joining the components to the PCB using solder. There are various soldering techniques, including wave soldering, reflow soldering, and hand soldering. Wave soldering is commonly used for through-hole components, while reflow soldering is used for surface mount components. Hand soldering is typically done for components that cannot be soldered using automated methods. The soldering process ensures a reliable electrical and mechanical connection between the components and the PCB.Inspection:After soldering, the PCB goes through an inspection process to check for any defects or errors. This is done toensure the quality and reliability of the assembled PCB. Various inspection techniques, such as visual inspection, automated optical inspection (AOI), and X-ray inspection, can be used to detect defects such as solder bridges, missing components, or misaligned components. Any defects found during the inspection process are rectified before proceeding to the next step.Testing:Once the PCB has passed the inspection process, it undergoes testing to ensure its functionality. Testing involves applying electrical signals to the PCB and checking if the desired output is obtained. Functional testing, boundary scan testing, and in-circuit testing are some of the commonly used testing methods. The goal is to verify that the assembled PCB meets the required performance specifications.Packaging and Shipping:After the PCB has been tested and verified, it is readyfor packaging and shipping. Packaging involves protecting the PCB from physical damage during transportation. This can be done by using anti-static bags, foam inserts, or custom packaging solutions. Once packaged, the PCB is ready to be shipped to the customer or the next stage of the manufacturing process.中文回答:简介:PCBA(Printed Circuit Board Assembly,印刷电路板组装)是电子设备制造过程中的关键环节。

pcb生产流程培训英文版Here is the English essay on the topic of "PCB production process training" with a word count of over 1000 words:The production of printed circuit boards (PCBs) is a crucial process in the electronics industry, as these components serve as the backbone for a wide range of electronic devices, from smartphones to industrial equipment. Ensuring the proper training and understanding of the PCB production process is essential for maintaining high standards of quality and efficiency. In this essay, we will delve into the various stages of the PCB production process, providing a comprehensive overview for trainees and professionals alike.The first step in the PCB production process is the design phase. This involves the creation of a digital schematic or layout, which outlines the placement and interconnections of the various components that will be mounted on the board. The design phase requires a thorough understanding of electrical engineering principles, as well as the specific requirements and constraints of the intended application. Designers must consider factors such as component size, heat dissipation, and signal routing to ensure the PCB will function asintended.Once the design is complete, the next step is the fabrication of the PCB itself. This process begins with the creation of the base material, which is typically a thin, rigid substrate made of fiberglass or other insulating materials. The substrate is then coated with a thin layer of copper, which will serve as the conductive pathways for the electronic components. The copper layer is then etched away, leaving behind the desired circuit patterns.After the basic PCB structure has been created, the next step is the drilling process. This involves the use of specialized machinery to create the necessary holes and vias that will allow the components to be mounted and interconnected. The drilling process must be carried out with a high degree of precision, as the placement and size of these holes can have a significant impact on the overall performance and reliability of the PCB.Following the drilling process, the PCB undergoes a series of cleaning and preparation steps to ensure that the surface is ready for the next stage of production. This may include the application of a solder mask, which is a protective coating that helps to prevent short circuits and corrosion, as well as the application of a surface finish, such as gold or tin, to improve the solderability of the board.Once the PCB has been prepared, the next step is the component placement and soldering process. This involves the use of specialized equipment, such as pick-and-place machines, to accurately position the various electronic components on the board. The components are then secured in place using a process called soldering, which involves the melting of a metal alloy to create a strong, conductive bond between the component and the PCB.After the component placement and soldering process, the PCB undergoes a series of quality control checks to ensure that it meets the required standards for performance and reliability. This may include visual inspections, electrical testing, and even more advanced techniques such as automated optical inspection (AOI) and X-ray analysis.Finally, the completed PCB is packaged and prepared for shipment to the end customer. This may involve the addition of protective coatings, the installation of connectors or other hardware, and the labeling and documentation of the PCB.Throughout the entire PCB production process, it is essential that workers and trainees receive comprehensive training on the various techniques and equipment involved. This training should cover not only the practical aspects of the production process, but also the underlying principles and best practices that guide the industry. Byensuring that all personnel involved in the PCB production process are well-trained and knowledgeable, companies can ensure that their products meet the highest standards of quality and reliability.In conclusion, the PCB production process is a complex and multifaceted endeavor that requires a deep understanding of electrical engineering, materials science, and manufacturing techniques. By providing comprehensive training to all personnel involved in the process, companies can ensure that their PCBs are produced to the highest possible standards, helping to drive innovation and advancement in the electronics industry.。

pcb生产流程的理解

pcb生产流程的理解英文回答:PCB Production Process.The PCB production process involves several sequential steps, each playing a critical role in creating afunctional and reliable printed circuit board. The primary stages of the process include:1. Design: The initial phase involves designing the PCB layout using specialized software. Designers consider factors such as component placement, signal routing, and power distribution.2. Artwork Generation: Once the design is finalized, artwork files are created representing the PCB's structure. These files serve as instructions for subsequent production steps.3. Photolithography: The artwork files are used to create a photomask, which is a transparent film with opaque areas representing the copper traces on the board. The photomask is placed over a copper-coated board, and ultraviolet light is used to expose the copper through the transparent areas.4. Etching: The exposed copper is then removed using an etching process, leaving behind the desired copper traces.5. Drilling: Holes are drilled into the board for component placement and through-hole connections.6. Lamination: A solder mask is applied to prevent solder from bridging between traces, and a silkscreen is used to label components and provide other markings.7. Solder Paste Application: Solder paste is applied to the pads where components will be placed.8. Component Placement: Components are placed onto the board using a pick-and-place machine.9. Reflow Soldering: The board is heated to a temperature that melts the solder paste, forming electrical connections between the components and the PCB.10. Inspection and Testing: The finished PCB undergoes thorough inspection and testing to ensure functionality and reliability.中文回答:PCB 生产流程。
