Wave soldering operation guidelines-Shengdian SMT equipment factory

1. Preparation:

Before carrying out the SMT equipment wave soldering oven, the first thing to do is to make preparations. Including checking the status of the equipment to ensure that all equipment is operating normally; check the solder temperature and flow controller, adjusted to the appropriate working condition; ready for the required soldering materials and auxiliary tools.

2. Check the printed board:

Before installation, be sure to carefully inspect the electronic components on the printed board. Check for damaged, misplaced or missing components to ensure the quality and stability of the soldering.

3. Setting the soldering temperature:

Set the appropriate soldering temperature according to the requirements of the soldering material and the actual situation. Usually, the solder temperature should be maintained between 230-260 ℃, which can ensure the quality and stability of the solder joint.

4. Control the flow of solder:

Proper solder flow is very important to obtain good solder joints. It is usually recommended to control the flow of solder between 40-60 milliliters per minute to ensure that the solder joint is fully wetted.

5. Set the pad height:

Wave soldering uses a wave shape of solder to achieve soldering, so the setting of pad height plays a key role in soldering quality. It is generally recommended to set the height of the pad between 1.5-2 mm to ensure that the solder can fully cover the solder joints.

6. Ensure that the soldering process is stable:

Before starting the soldering process, test soldering is required to ensure the stability and reliability of the soldering process. Check the appearance and strength of the solder joints and make adjustments and optimizations as needed.

7. Pay attention to post-welding treatment:

Immediately after welding is completed, post-weld treatment should be performed. This includes trimming stray solder around the solder joint, removing residual slag, etc. This will help improve the appearance of the solder joint. This will help improve the appearance and strength of the solder joint. Shengdian SMT equipment factory
