Information

The SMT chip processing production process must have a strict standardized process to avoid errors in the process of high-frequency line replacement and material replacement. In addition, in the process of processing, the placement machine equipment must be checked regularly. Next, the editor of Tongsen Electronics will introduce the relevant content to you in detail.

 

1. The process of producing SMT patch

 

1. Remove the feeder from the SMT placement machine and take out the used paper tray.

 

2. The SMT operator can reclaim the material from the material rack according to his own station.

 

3. The operator checks the removed material using the job number sheet to confirm that the specification and model are the same.

 

4. The operator inspects the new pallet and the old pallet, and checks that the specifications and models of the two pallets are exactly the same.

 

5. The operator checking its material can tell if the business is consistent with the pallet.

 

6. If there is any abnormality, the SMT patch operator should immediately notify the delayed processing.

 

7. Take a sample from the new pallet and park the material on the old and new pallets.

 

8. Take the newly installed Feida material, paste it on the refueling process record sheet, and fill in the refueling working time, operator management and other relevant data.

 

9. Put the feeder back into the mounter according to the SMT mounter station; you need to fill in your supplementary information record effectively.

 

10. The operator should notify the engineering quality management personnel for material matching and testing, and for material modification and inspection.

 

11. IPQC checks whether the data information can be correctly developed and whether the site is correct according to the site number table.

 

12. Before the start of production, the operation inspection of the above placement machine has been completed.

2. Precautions for SMT chip processing

 

1. When processing SMT patches, everyone knows that solder paste is basically used. For the newly purchased solder paste, if the SMT factory does not use it immediately, it needs to be stored in an environment of 5-10 degrees so as not to affect the use of the solder paste. It must not be placed in a sub-zero environment. It is not possible if it is higher than 10 degrees.

 

2. During the placement process, the placement machine equipment must be checked regularly. If the SMT factory equipment is aging or some parts are damaged, in order to ensure that the patch will not be bent and high throwing occurs, it is necessary to repair or replace the equipment in time. Only in this way can production costs be reduced and production efficiency be improved.

 

3. During SMT chip processing, if you want to ensure the quality of SMT chip processing and welding, you need to pay attention to whether the setting of the technical parameters of the reflow soldering process is reasonable at any time. If there is a problem with the parameter settings, the quality of SMT patch welding cannot be guaranteed. Therefore, in general, the furnace temperature needs to be twice a day.

 

The above is all the content that should be paid attention to when SMT chip processing and production. If you have any questions or suggestions, please contact us.
