Cleaning Process of China Turnkey PCB Assembly

1. Fully automated online cleaning machine

A fully automatic on-line cleaning machine, the cleaning machine is aimed at the residual rosin flux, water-soluble flux, no-cleaning flux/solder paste and other organic and inorganic pollutants on the surface of SMT/THT China turnkey PCB assembly after welding. Thorough and effective cleaning. It is suitable for large-volume turnkey PCB assembly cleaning.

2. Semi-automatic off-line cleaning machine

A semi-automatic off-line cleaning machine, which thoroughly and effectively cleans organic and inorganic pollutants such as rosin flux, water-soluble flux, no-clean flux/solder paste, etc. remaining on the surface of SMT/THT turnkey PCB assembly after welding cleaning.

3. Manual washing machine

A manual cleaning machine (also known as a constant temperature cleaning tank), which is aimed at the residual rosin flux, water-soluble flux, rosin flux, no-cleaning flux/solder paste on the surface of SMT/THT turnkey PCB assembly after welding thorough and effective cleaning of organic and inorganic pollutants.

China Turnkey PCB Assembly Processing

1) According to the customer's Gerber file and BOM list, make the process file of SMT production, and generate the SMT coordinate file

2) Check whether the production materials are ready, and confirm the PMC plan for production

3) Carry out SMT programming, and make the first board for checking to ensure that it is correct.

4) According to the SMT process, make laser steel mesh

5) Carry out solder paste printing to ensure that the printed solder paste is uniform, good in thickness, and consistent.

6) Mount the components on the circuit board through the SMT placement machine, and perform online AOI automatic optical inspection if necessary

7) Set the perfect reflow soldering oven temperature curve, let the circuit board flow through the reflow soldering, the solder paste will transform from paste, liquid to solid, and good soldering can be achieved after cooling.

8) IPQC intermediate inspection

9) The DIP plug-in process passes the plug-in material through the circuit board and then flows through wave soldering for turnkey PCB assembly welding.

10) Post-furnace process, such as cutting feet, post-welding, board surface cleaning, etc.

11) QA conducts a comprehensive inspection to ensure the quality is OK.
