Workflow of SMT mounter:

The work flow function of the SMT machine is mainly through the PCB board fixing -> component suction -> displacement -> positioning -> component placement and other operations.

First, the PCB board to be mounted enters the work area and is fixed in the predetermined position;

Second, the component material is installed in the feeder, and according to the position set in the program, installed to the position of the sticker head;

Third, the sticker head will move to the position of picking up the component, open the vacuum, the suction mouth is lowered to absorb the component, and then through the vacuum sensor to detect whether the component is sucked;

4, component identification, read the component characteristics of the component library and pick up components to compare, if the comparison evaluation does not meet, then the component is thrown into the scrap box, if the comparison evaluation meets the center position and Angle of the component calculation;

5. According to the Settings in the program, the rotation Angle of the component is adjusted through the Z-axis of the sticker head, and the position set by the program is moved through the sticker head, so that the center of the component coincides with the PCB board mounting position;

Six, the placement machine nozzle will drop to the height set by the program, close the vacuum, the component falls, and the sub-component mounting operation is completed;

7. After all the components are installed, the nozzle is placed back in place and the PCB board is transferred to the set position. Complete the entire PCB board mounting operation.

SMT reflow soldering workflow:

Manual, semi-automatic or automatic paste presses can be used to print solder paste onto the printed board as a mimeograph, and then manually or automatically attach the components to the printed board. The welding paste is heated to reflow by heating furnace or hot air, and the heating temperature needs to be controlled according to the melting temperature of the welding paste. This process includes preheating zone, reflow zone and cooling zone. The high temperature in the reflow area causes the solder paste to melt and the adhesive and flux to vaporize into smoke.

SMT solder paste printing machine process workflow:

For the operation method of solder paste printing machine, the part is to turn on the switch, let the machine zero, then select the operation procedure you need; This is the step of preparation work, we summed up the 8 words called open zero, select the program;

After the step is done, it begins to install the support frame, and then adjust the required width and adjust it directly to the point you need. If it is not adjusted well, it will affect the later work, and then start to move the baffle, turn on the switch, note that the switch is not the machine, but the transport switch, so that our board is placed in the middle, and then reached the designated position;

When the above installation program is ready, start adjusting the computer interface to correspond to the "ten" in the middle. Confirm that your data is correct, and if it is wrong, you can click the OK button.

Then install the scraper, the scraper is installed to adjust the position, the adjustment before and after, and so on to determine the correct installation, open the mediation window, then the production begins;

Why is the solder paste printing machine called this name, it can be reflected in this step, then start to add the solder paste, the principle of adding is to be higher than the position of the scraper three points, not more and not less, to grasp this amount;

When the solder paste is added, it is checked, and it is necessary to check whether the printed solder paste is biased, or even tin. Of course, pay attention to whether the thickness is even, which need to pay attention to. If you do not pay attention to good, then the printed products are not qualified, so it is necessary to check the perfection of the product.

In order to reduce the waste of costs, we should first brush out the piece to check whether the product is qualified. If it is found that it is qualified, it can be printed, but if it is not qualified, it needs to be adjusted again, do not blindly print more than N, if the piece is not checked, if it is unqualified, the following are unqualified, then the waste is more serious, so it is necessary to check. The workflow of the solder paste printing machine is not difficult, but we need to be careful, each step needs to be carefully operated, and then step by step to ensure that each step is correct, so that the printed product is perfect.

The three kinds of SMT machine and reflow soldering and solder paste printing machine are SMT production process equipment, and the relationship between them is the sequence of the production line, the circuit board is printed by the solder paste printing machine, and then the circuit board of the patch components is reflow soldering. The quality of the products produced by SMT and solder paste printing machine, patch machine, reflow soldering these three kinds of SMT production equipment production process is good or bad, the previous production equipment production product quality is not up to standard behind the production equipment can not make good products.
