SMT chip processing of smart coffee machine circuit board
What is SMT chip processing?
SMT processing is surface mounting technology, which is to place components with a chip structure or miniaturized components suitable for surface assembly on the surface of the PCB board as required, and then use soldering processes such as reflow soldering to complete the electronics. Component assembly technology.
On the SMT chip processing circuit board, the solder joints and components are on the same side of the board, so on the SMT chip processing PCB board, the through holes are only used to connect the wires on both sides of the circuit board. The number of holes must be Much less, and the diameter of the hole is much smaller. And such a design can greatly increase the component mounting density of the PCB board.
Which is better for SMT patch processing
The size and volume of the chip components used in SMT chip processing are much smaller than those of traditional plug-in components. Generally speaking, they can be reduced by 60% to 70%, and may be reduced by 90%. The weight is reduced by 60% to 90%. This can meet the development needs of miniaturization of electronic products. The components processed by SMT patch are usually leadless or short lead, which reduces the distribution parameters of the circuit and thus reduces the radio frequency interference.
The PCB board processed by SMT patch has a compact structure and high mounting density, which can achieve the effect of short connection and small delay, and then achieve high-speed signal transmission. At the same time, it can make electronic products more resistant to vibration and shock. SMT placement processing simplifies the production process of electronic complete machine products, effectively reduces production costs, effectively shortens the entire production process, and improves production efficiency.
SMT贴片加工的操作注意事项
SMT贴片加工的好坏决定了电子产品的品质,因此SMT贴片加工的操作过程非常重要,那么该怎样进行操作?SMT贴片加工操作注意事项又有哪些?下面来让我们一起去了解下:
SMT贴片加工哪家好
SMT贴片加工工作区域内不得有食物或饮料,严禁吸烟,不得放置与工作有关的杂物,维持好干净整洁。对于SMT贴片加工敏感的部件和产品,必须适当的进行标记,以防止与其他部件混淆。检查好SMT贴片加工转接线,以确保它们的功能性。
焊在SMT贴片加工表面上的贴片不能用手或手指进行拾取,因为手部的油量会使焊接产生缺陷。最大限度地减少操作步骤和部件,以防止危险。在必须使用手套的组装区域,不可使用脏手套,脏手套会造成SMT贴片加工的污染,需要根据实际情况更换手套。
DIP插件后焊加工工艺与注意事项
DIP插件后焊加工是PCBA贴片加工中非常重要的一到工序。加工质量直接影响PCBA板的功能特性,因此必须要注重DIP插件后焊加工付哦成。 DIP插件后焊加工有很多准备工作。首先是对电子元器件进行加工。工作人员按照物料清单领取物料,检查物料型号和规格是否正确,并根据PCBA模板进行生产前的预处理。
DIP插件后焊加工哪家好
DIP插件后焊加工注意事项:
1、DIP插件后焊加工时,元器件引脚伸出至PCB焊盘的距离不要太大,零件需要利用治具成型,以提供机械支撑,以防焊盘翘起。
2、PCBA加工在进行DIP插件后焊加工工艺时,工作人员必须佩戴防静电手环、防静电手套,穿防静电鞋,头戴防静电帽,防止发生静电,按照元器件BOM清单及元器件位号图进行插件,DIP插件后焊加工时按顺序有序进行,要仔细一点不能出现差错。
