SMT chip processing technology advantages and development trends
SMT patch processing refers to the abbreviation of a series of technological processes that are processed on the basis of PCB. PCB is a printed circuit board. SMT patch processing is a surface assembly technology, which is the most popular technology and process in the electronic assembly industry. SMT patch processing surface assembly technology is called surface mounting or surface mounting technology. It is a type of surface-mounted components without leads or short leads (referred to as SMC/SMD, referred to as chip components in Chinese) installed on the surface of a printed circuit board or other substrates, through reflow soldering or dip soldering, etc. Method of soldering and assembling circuit assembly technology.
Which is better for SMT patch processing
The advantages of SMT chip processing: high assembly density, small size and light weight of electronic products. The volume and weight of SMT chip processing components are only about one-tenth of that of traditional plug-in components. After SMT chip processing, the volume of electronic products Reduced by 40%~60%, weight reduced by 60%~80%. High reliability, strong anti-vibration ability, low defect rate of solder joints, good high-frequency characteristics, reducing electromagnetic and radio frequency interference. SMT patch processing is easy to automate and improve production efficiency. Reduce costs by 30%~50%. Save materials, energy, equipment, manpower, time, etc.
Which is better for SMT patch processing
Because of the complex process flow of SMT chip processing, many SMT chip processing factories have appeared for this purpose, specializing in SMT chip processing, and also benefiting from the vigorous development of the electronics industry, SMT chip processing has become an industry Prosperity scene. The future development trend of SMT chip processing industry will also be towards smart factories and smart production. Due to the progress of society and the continuous improvement of people's living standards, the cost of labor is also rising. With the continuous maturity of the process and the rapid development of automation and intelligence, labor costs have been reduced and employees have become many factories. The main way to reduce costs is to optimize the process that can be optimized. The process that cannot be optimized is simplified as much as possible, and no one can replace it with equipment and robots.
东莞SMT贴片加工工艺构成要素
SMT贴片加工指的是在PCB基础上进行加工的系列工艺流程的简称,是目前电子组装行业里最流行的一种技术和工艺。在通常情况下SMT贴片加工电子产品都是由pcb加上各种电容,电阻等电子元器件按设计的电路图设计而成的,所以形形色色的电器需要各种不同的SMT贴片加工工艺来进行加工。
SMT贴片加工基本工艺构成要素: 锡膏印刷--> 零件贴装-->回流焊接-->AOI光学检测--> 维修--> 分板。
SMT贴片加工哪家好
SMT贴片加工的优点：组装密度高、电子产品体积小、重量轻，贴片元件的体积和重量只有传统插装元件的1/10左右，一般采用SMT贴片加工之后，电子产品体积缩小40%~60%，重量减轻60%~80%。 可靠性高、抗振能力强。焊点缺陷率低。高频特性好。减少了电磁和射频干扰。易于实现自动化，SMT贴片加工提升生产效率。降低成本达30%~50%。节省材料、能源、设备、人力、时间等。
深圳SMT贴片加工中助焊剂的好处与作用
在深圳SMT贴片加工中助焊剂在焊接中的作用与好处体现在以下4个方面：
１、在SMT贴片加工中助焊剂有利于热量传递到焊接区。助焊剂降低了熔融焊料的表面张力和粘度，从而增加了液态焊料的流动性，从而促进了热量快速有效地传递到焊接区并加快了扩散速度。
２、在SMT贴片加工中助焊剂降低熔融焊料的表面张力，并促进焊料的膨胀和流动。当去除焊料表面的氧化物时，助焊剂会发生某种化学反应。化学反应过程中释放出的热量和活化能可以降低表面张力和熔融焊料的程度，同时获得金属表面的活化能并促进液态焊料的生长。待焊接金属的表面流动，增加了表面活性，从而提高了焊料的润湿性。

３、从SMT贴片加工的焊料表面去除氧化物或其他污染物。 SMT贴片加工处理焊接之前的主要任务是从焊料表面去除氧化物。在活化温度范围内，助焊剂中的松香酸会随着待焊接金属表面的氧化膜而被还原，从而形成松香酸铜，该松香酸容易与不参与反应的松香混合并保留在裸露的金属铜的表面以使焊料流动。湿。助焊剂中的活性剂与氧化铜反应，最终替代纯铜。助焊剂中的金属盐与待焊接金属的表面氧化物发生置换反应。助焊剂中的有机卤化物也与要焊接的金属表面反应以去除氧化物。
４、在SMT贴片加工处理过程中，防止焊料和焊接表面再次氧化。焊剂的比重小于焊料的比重。因此，助焊剂在焊接过程中覆盖焊接金属和焊料的表面，从而使焊接金属和焊料的表面与空气隔离，并且可以有效地防止金属表面在高温下被再氧化、焊接。
