1. The daily maintenance of reflow soldering is to check the amount of lubricating oil in the automatic oiler, the lubrication of the transportation chain and whether there is dirt in the oiler;

Second, the weekly maintenance content of reflow soldering is divided into:

1. Check the transportation part of reflow soldering

Check the operation of gears, bearings, drive motors, wind motors, etc.

2. Check the cooling area of ​​reflow soldering

Check whether the cooling zone pipeline is leaking or cannot reduce the temperature of the cooling zone;

3. Check the oxygen analysis filter for reflow soldering (optional)

Check or replace the filter installed at the inlet or outlet of the oxygen analyzer;

4. Check the reflow soldering heat exchanger

Check the debris and debris accumulated in the cooling area, and clean the air distribution plate of the heat exchanger;

Third, the monthly maintenance content of reflow soldering:

Monthly heating wire test for reflow soldering

Test the furnace temperature, including the heating time, the temperature difference at the sampling point, the resistance value of the heating wire, etc.

4. Quarterly maintenance content of reflow soldering (grandseed.com)

Conduct one-time oxygen analyzer water inspection for reflow soldering every quarter: check the oxygen analyzer pool to ensure that the water volume is between the maximum and minimum indicator lines to avoid excessive water volume

5. Maintenance of reflow soldering every six months

Semi-annual inspection of reflow soldering transport rails

Check the spacing of the transport rails for changes, check the adhesion of the flux on the rails and the chain, and the deformation and wear of the rails.
