Foshan SMT patch processing needs to know
With the development of science and technology, many electronic devices are developing in the direction of small and fine, which makes the size of many SMT components smaller and smaller. Not only the standard of processing environment is constantly improving, but also there are higher requirements for SMT SMT SMT processing technology. Next, let's introduce in detail the key points that need to be concerned about SMT patch processing.
First, when processing SMT patches, we all know that solder paste needs to be used. For the solder paste just purchased, if it is not used immediately, it must be placed in an environment of 5-10 degrees for storage. In order not to endanger the use of solder paste, it must not be placed in an environment less than zero degrees, and it cannot be placed higher than 10 degrees.

Second, during the mounting process, the equipment of the mounter must be inspected frequently. If the equipment is aging or some parts are damaged, in order to ensure that the mounter will not be skewed and high throwing, the equipment must be repaired or replaced with new equipment. Only in this way can we reduce production costs and improve production efficiency.
It can be said that the technical level of SMT patch processing is very high. We must pay attention to these key points in the processing process. If you don't pay attention to these key points and blindly want to improve production efficiency, the quality of processed products will have problems, and the sales volume of goods will be greatly affected.

『中山SMT贴片加工』焊锡注意事项
随着时代的不断进步，许多厂家里面都有SMT贴片加工这类技术，这类技术得到了很大的反响，但是其中有一些问题是需要注意的，比如在加工焊锡方面就有很多注意事项：
SMT贴片加工焊接加热桥的过程不正确。SMT贴片加工中的焊接热桥是阻止焊料形成了桥接，要是这一流程操作不得当，就会造成冷焊点或焊料流动不充份。因此正确的焊接方式应当是将烙铁头摆放在焊盘与脚位中间，锡线靠近烙铁头，待锡熔时将锡线移至对面，或者是将锡线放置于焊盘与引脚之间，烙铁摆放于锡线之上，待锡熔时将锡线移至对面;这样才能够产生良好的焊点，防止对贴片的加工造成不良影响。
SMT贴片加工转移焊接操作不当。转移焊接是指将焊料先加在烙铁头，然后再转移到连接处。而不恰当的转移焊接会损伤烙铁头，造成润湿不良。所以正常的转移 焊接方式应当是烙铁头放在焊盘与引脚之间，锡线靠近烙铁头，待锡熔时将锡线移至对面。将锡线放置于焊盘与引脚之间。烙铁放置于锡线之上，待锡熔时将锡线移至对面。

SMT贴片加工助焊剂的使用不当。据有关统计，许多工作人员在SMT贴片加工的过程中习惯使用过多的助焊剂，其实这不仅无法帮助你得到一个好的焊点，而且还特容易引发下焊脚是否可靠的问题，比较容易产生腐蚀，电子转移等问题。
SMT贴片加工温度设定不正确。温度也是焊接过程中的一个重要因素，如果温度设定过高会造成焊盘翘起，焊料被过度加热以及损伤电路贴片。因而设定正确的温度对贴片加工的质量保证特别重要。
在SMT贴片加工的时候，对引脚焊接用力过大。很多SMT贴片加工厂的工作人员认为用力过大能够促进锡膏的热传导，加快焊锡的效果，因而习惯在焊接时用力往下压。其实这是一个坏习惯，容易造成贴片的焊盘出现翘起、分层、凹陷，PCB白斑等问题。所以在焊接的过程用力过大是完全没必要的，为了确保贴片加工的质 量，只需要将烙铁头轻轻地接触焊盘就可以了。

珠海SMT贴片加工技术与特点
SMT贴片加工是表面组装技术（表面贴装技术），是电子组装行业里最流行的一种技术和工艺。电子电路表面组装技术，称为表面贴装或表面安装技术。SMT贴片加工它是一种将无引脚或短引线表面组装元器件（简称SMC/SMD，中文称片状元器件）安装在印制电路板（PCB)的表面或其它基板的表面上，通过再流焊或浸焊等方法加以焊接组装的电路装连技术。
SMT贴片加工哪家好
SMT贴片加工的特点：
SMT贴片加工组装密度高、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，通常采用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，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。
SMT贴片加工其作用是将表面组装元器件准确安装到PCB的固定位置上。SMT贴片加工所用设备为贴片机，位于SMT生产线中印刷机的后面。SMT贴片加工厂就是将贴片元器件安装到PCB的固定位置上。就同以前的插件线一样。
