What does the SMT manufacturing shop in the electronics factory do?
Some workers who entered the electronics factory for the first time heard that they were assigned to the SMT manufacturing workshop, so they had a question: what is the SMT workshop? How difficult is the job? Is it dangerous? Are you tired? This article will give you a graphic, easy to understand the introduction of SMT workshop SMT production line and DIP production line.

Doubts about SMT workshop

Today, Xiaobian will give you a brief introduction to the SMT manufacturing workshop according to the information provided by relevant people in the industry. If you have any questions, you can contact me (my micro-number is hechina168).

The SMT workshop in the electronics factory is generally divided into SMT line and DIP line.

SMT workshop production line planning

SMT refers to Surface assembly Technology (also known as surface mount technology) (is the abbreviation of English Surface Mounted Technology), it is the most popular technology and process in the electronic assembly industry. In simple terms, SMT is to attach electronic components to the PCB board through the equipment, and then heated by the furnace (generally refers to the reflow furnace, also known as the reflow welding furnace), and weld the components to the PCB board through the solder paste.

The basic process of SMT is: solder paste printing --> Parts mounting --> reflow welding -->AOI optical inspection --> Maintenance --> sub-board.

DIP is the plug-in, DIP pipeline is the plug-in welding pipeline, and some enterprises are also called PTH and THT, which are the same meaning. DIP has some large connectors, the device is not able to hit the PCB board, then it is necessary to plug into the PCB board through people or other automation equipment.

The main process of DIP plug-in is:

DIP plug-in main process flow

SMT line mainly includes solder paste printer, material worker, pre-furnace eye inspection, post-furnace eye inspection, packaging and so on.

DIP line mainly includes board casting personnel, plate removal personnel, plug-in personnel, furnace workers, after the furnace welding spot eye inspection.

SMT workshop working environment

Question 1:

Is SMT workshop work harmful to human body?

SMT workshops generally need to be ventilated, and employees need to wear overalls and protective gloves during work, because they will be exposed to some chemical agents during work. In the case of good protection, there is no major harm to human health, but if it is allergic, it is necessary to report and test in advance to prevent accidents.

Question 2:

How about SMT work?

SMT production line solder paste printing machine, patch machine, reflow welding (such as Haobao automatic lead-free reflow welding machine) and other equipment has been basically automated, the operator is basically standing guard, during the work is able to walk, because the need to take materials and other items. The labor intensity of the post is general, you need to understand some professional knowledge of machine operation, if you take the initiative to learn the maintenance of equipment through your own efforts, then there is also a skill in the future job search, which can be regarded as a technical post.
