Shenzhen SMT chip processing services
SMT patch processing plants can be found everywhere, especially in Shenzhen. As we all know, Shenzhen's electronics and electrical appliances are famous all over the world. Many large and medium-sized companies must also quietly launch SMT production lines in order to cooperate with commodities. Among many SMT chip processing plants, how to choose the SMT chip processing plant with better service? Good service SMT chip processing factory has the advantages! Next, Xing Enyu will give you a brief introduction!
1. SMT chip processing products have small volume and light weight
The volume of SMT components is only about one tenth of that of traditional plug-in components. Generally, after SMT chip processing, the volume of electronic products is reduced by 40% ~ 60%. The weight of SMT components is only 10% of that of traditional plug-in components. Generally, after SMT is adopted, the weight is reduced by 60% ~ 80%.

2. SMT chip processing has high reliability
Due to the high reliability of chip components, small and light components, it has strong seismic resistance. It adopts automatic production and high mounting reliability. Generally, the rate of defective solder joints is less than 10 parts per million, which is one order of magnitude lower than the wave soldering technology of through-hole plug-in components. The MTBF of electronic products assembled with SMT is 250000 hours on average. At present, almost 90% of electronic products adopt SMT process.
3. SMT chip processing has high productivity
SMT automatic Mounter adopts vacuum nozzle to absorb and release components. The vacuum nozzle is smaller than the component shape, but improves the installation density. In fact, small components and fine spacing QFP devices are produced by automatic Mounter to realize automatic production of the whole line. SMT chip processing is easy to realize automation, improve production efficiency, save materials, energy, equipment, manpower and time, and reduce the cost by 30% ~ 50%. At present, in order to realize the complete automation of the perforated installation printed board, it is necessary to expand the area of the original printed board by 40%, so that the inserting head of the automatic plug-in can insert the components, otherwise there is not enough space gap, and the parts will be damaged.

4. SMT chip processing cost is low
The reduction of the number of holes drilled on the printed board saves the cost of repair; Moreover, due to the improvement of frequency characteristics, the cost of circuit debugging is reduced; Due to the small volume and light weight of chip components, the cost of packaging, transportation and storage is reduced. Therefore, using SMT chip processing technology can save materials, energy, equipment, manpower and time, and reduce the cost by 30% ~ 50%.

广州DIP插件后焊加工的流程
DIP插件后焊加工的方法具体有浸焊、波峰焊、回流焊三种。
1、浸焊
浸焊是将插装上元器件的印制电路板在熔化后的锡槽内浸焊，一次完成印制电路板诸多焊点的焊接方法。不但比手工焊接更有用，并且可清除漏焊的现象。浸焊也分成手工焊接和机器自动焊接两种方式。
2、波峰焊
波峰焊是选用波峰焊机一次完成印制电路板上全部焊点的焊接。通常用来自动焊接生产。机械泵持续的从喷嘴中压出液态锡波，当印制电路板利用时，焊锡以波峰的方式持续的溢出至印制电路板面进行焊接。波峰焊分成单波峰焊、双波峰焊、多波峰焊和宽波峰焊等。

3、回流焊
回流焊是利用重新熔化事先分配到印制电路板上的焊膏，实现外表组装元器件的焊端或引脚与印制板焊盘之间的机械与电气连接的一种焊接方法。通常用来自动生产中，进成组或逐点焊接。
回流焊的技术优点取决于元器件接到的热冲击小、高温受损的几率小和很好的控制焊料的施加量。依据加工方法的不一样，回流焊分成气相回流焊、红外回流焊、热风循环回流焊这些。
看到这里，大家针对DIP插件后焊加工的流程多多少少应当都有所了解了吧？针对有需求的顾客来讲，只有选好DIP插件后焊加工厂，才可以确保电子产品品质和交期，真正地做到省心省力。

SMT贴片加工的优势及注意事项
SMT是表面组装技术，是现阶段电子组装行业里最盛行的一种技术和工艺。SMT贴片加工主要指把元件利用贴处设备贴到印有胶或锡膏的PCB上，随后过焊接炉。smt贴片加工以组装密度高、电子商品体积小、高频特性好等优势获得厂家认同。
由于SMT贴片机高效的工作效率和稳定的性能为我们的生产带来了很大的优势，有了SMT贴片机，就能进一步提高生产率和能提供高质量的商品给顾客。SMT贴片机想当于一个贴片机器人，是较为精密的自动化生产设备，因此SMT贴片机操作注意事项必须要了解。
SMT贴片加工操作及注意事项：
SMT贴片加工
1、SMT贴片机器操作之前必须先了解贴片机的常用标示标签；
2、SMT贴片机开机前操作人员要做好机器的全方位检查；
3、必须严格遵守SMT贴片机的开机操作顺序；要有具体的SMT贴片机作业指导书；
4、要及时按时的对SMT贴片机进行故障排查及保养工作。
SMT贴片加工的优势：
SMT贴片加工
1、电子商品体积小（贴片元件的体积只有传统式插装元件的1/10左右，通常SMT贴片加工过后，电子商品体积缩小40%~60%）。
2、功效且成本低（SMT贴片加工容易实现自动化，提升生产率，节约材料、能源、设备、人力、时间等，控制成本达30%~50%）。
3、重量轻（贴片元件的重量也只有传统式插装元件的10%，通常选用SMT过后，重量降低60%~80%）。
4、可靠性高，抗振能力强。
5、高频特性好，减少了电磁和射频干扰。
6、焊点缺陷率低。
