Wave soldering problems, what do you need to pay attention to in wave soldering, is it easy to opera

Need the product ** to analyze, mainly because of the influence of moisture, PCB, device flux and other reasons, it is recommended to change a flux to see if there is any improvement!!

The main cause of the formation of solder beads.

Damp. 2.Use a no-clean, water-based flux.

3.Tin impurities exceed the standard.

I don't know what your company's product is, IPC-A-610C has written less than 5 tin beads within 600 square millimeters as acceptable, and the premise is that the solder beads do not form a minimum electrical spacing.

You can adjust the slope of the track.

I don't know if you use a mold for PCB, if you use a mold, you can check if there is a gap between the mold and the PCB.

Has the flux ever been changed.

Maintenance, operation, maintenance.

As for whether it is good or not, you will know if you try it.

People with strong receptivity can operate freely in about two or three days, and if they are a little weak, it will take about a week.

It takes at least three months to become proficient and at least one year to become proficient.

It takes two years to know it.

In fact, it all depends on the individual, you work hard to learn everything, and you can be proficient in three months.

You don't learn anything, you're lazy, and you won't be able to master it in three years.

To put it simply, wave soldering is composed of several resistors, several inductors, and several motors.

It's simple, but it's a bit difficult to go deeper.

For example, after maintenance, what are the deficiencies of the wave soldering hardware in the usual work, and how to improve it.

Notes:1High temperature precautions, 2

Whether the entrance is in a straight line.

For the operation, it is now fully computerized, and it is easy to master.

Summary. 1. Common problems of argon arc welding: (1) Insufficient welding current:

It may be that the welding conditions are not set properly, and you can try to increase the current; (2) The welding temperature is too high: it may be that the welding nozzle is too large, and you can try to reduce the size of the welding nozzle; (3) The welding temperature is too low: it may be that the welding nozzle is too small, you can try to increase the size of the welding nozzle; (4) The welding arc is unstable

It may be that the electrode surface area is too small, and you can try to increase the electrode surface area; (5) Unstable welding arc: it may be that there is an interfering electromagnetic field in the welding environment, which can reduce the impact of interfering electromagnetic field; (6) Shrinkage of the welding head: It may be that the welding current is too large, and you can try to reduce the current; (7) Shrinkage holes appear in the welding head

It may be that the welding speed is too fast, you can try to slow down the welding speed; (8) Cracks in the welding head: It may be that the welding conditions are not suitable, and you can try to readjust the welding conditions.

Hello, I'm E-Info, I'm happy to answer for you, the following is the answer I got for you, I hope it will help you with your questions:

1. Common problems of argon arc welding: (1) Insufficient welding current: it may be that the welding strip is improperly set, and you can try to increase the current; (2) The welding temperature is too high

It may be that the nozzle is too large, try to reduce the size of the nozzle; (3) The welding temperature is too low: it may be that the welding nozzle is too small, you can try to increase the size of the welding nozzle; (4) The welding arc is unstable: it may be that the electrode surface area is too small, and you can try to increase the electrode surface area; (5) The arc of the lifting connection before the welding god is unstable

It may be that there is an interfering electromagnetic field in the welding environment, which can reduce the influence of interfering with the electromagnetic field; (6) Shrinkage of the welding head: It may be that the welding current is too large, and you can try to reduce the current; (7) Shrinkage holes appear in the welding head: it may be that the welding speed is too fast, and you can try to slow down the welding speed; (8) Cracks appear in the welding head:

It may be that the welding conditions are not suitable, and you can try to readjust the welding conditions.

Hello, I am very happy to answer 1Wave soldering solution:- You can adjust the wave soldering parameters, such as soldering temperature, time, speed, etc., to ensure the quality of soldering.

Check the status of the welding equipment to ensure the stability of the equipment and the humidity of the metal device. - Inspect the welding materials to ensure the purity and quality of the materials. - Check that the surface of the welded material is smooth, and if not, use sandpaper or a wire brush to smooth it out.

2.Solutions for cold welding:- Increase the welding temperature and time between the lead cars to ensure the complete melting of the metal material.

Check the welding equipment and power supply** to ensure that it is stable and working properly. - Inspect the welding material to ensure its purity and quality, and replace it if it is defective. - Check whether the heating temperature of the welding material meets the specified specifications.

Check the contact area, increasing the contact area can improve the quality of the weld. Hope mine is helpful to you.

Wave soldering: generally large 4500-5500 mm medium town absolute 3000-4000mm small 2000-3000 mm classification In addition, the conventional type on the market is now double wave soldering structure wave soldering, and the traditional single wave soldering and high wave soldering are two unconventional wave soldering.

High-end wave soldering, usually multi-stage wave soldering, spray preheating soldering and separate transmission structure, better control the fine parameter control of the functional area in different early brigades, the disadvantage is high manufacturing cost!

According to the process, it can be divided into leaded process and lead-free process wave soldering.

There are also different extended functions in the market, and DIP soldering equipment can also be regarded as a large category of wave soldering products:

Selective wave soldering: A device for small batch soldering.

Automatic dip welding machine: small and medium-sized batch multi-product Lushan double-sided mixed welding equipment.

Plane jet equipment: long-legged process and small batch welding equipment.

As long as plug-in components exist, wave soldering will not be eliminated. Now you should learn RoHS wave soldering equipment. In March this year, China implemented lead-free electronic products, and the European Union has implemented it in July last year.

The current salary of the wave soldering brother Li Equipment is about 3k.
