Stainless steel plate anti static wave soldering

Hehe, your leaders have money, shop it, there is no problem, but the cost is a little higher. However, anti-static is not only solved by laying stainless steel floors, first of all, your stainless steel plates should be connected to each other and reliably grounded. The main thing is that the clothing of the workers working inside should be anti-static.

It is best to establish appropriate anti-static measures as needed.

Stainless steel plate can be used, regardless of the cost but need to consider safety issues, especially the design of grounding and daily operation, hard grounding is prone to problems, need to use soft grounding, and at the same time pay special attention to the safety protection of personnel.

This layer of iron sheet is mainly used to dissipate heat and eliminate electrostatic charges, and it is generally grounded.

The main thing is to prevent rats or metal shavings.

I can't see **, I can only guess, it is estimated that it is anti-static, or it is connected to the spilled tin slag.

Wear anti-static overalls.

Do anti-static flooring and test it regularly.

Wear anti-static overalls, shoes and other protective equipment.

PCB board soldering DXT-398A flux, some products do not need to be soldered, you can use some materials to stick up or patch up after soldering.

The industrial practice is generally to use solder mask tape to paste the parts that do not need to be soldered, and tear them off after wave soldering.

Solder mask tape is generally yellow and resistant to high temperatures, with a paper feel, which is different from ordinary tape, so don't get confused.

Protect the area with high-temperature resistant tape first. After walking the solder, on the screws.

Remove the stainless steel screws from the PCB board and then go.

Coating stainless steel screws with plaster will do.

Please contact me with a careful inquiry.

First, how to repair wave soldering.

The tin inside gets out.

1.A number of stainless steel basins are prepared, the number is generally not less than ten, when the container is used to cool the tin; a pair of high-temperature gloves and a stainless steel spoon;

2.Use a spoon to scoop it out of the tin tank and cool it in a stainless steel basin, otherwise it will be very troublesome when you put it back in the furnace.

3.The agglomerated and cooled tin can be poured out of the stainless steel basin for cooling, and the stainless steel basin can continue to be recycled;

Second, the wave soldering furnace can't get in after it comes out.

The height of the chain needs to rise, and the height of your tin bath needs to be reduced, or there will be no interference, because the height of the tin bath and the height of the tin bath nozzle can be adjusted at any time, so it will be changed during the production process or when you maintain it, so when the change is not guaranteed, when you have to go back again, you must lower the tin bath to the original height to put it in.

Third, the wave soldering furnace crest can not be hit because there is a problem.

1.There is too much solder in the solder pot nozzle, so it is recommended to clean it once a week.

2.The tin guide groove is perforated, and the general life of the tin guide is about one and a half years, if it has been determined that it is a tin guide tank, it is recommended to replace the tin guide groove.

3.The motor coil is aging, and it is recommended to replace the motor. You can debug the inverter to check, hit the peak to the number of revolutions you usually pass the PCB, if the motor stops automatically, or overload, it means aging.

4.The inverter is damaged.

Generally, synthetic stone is used as the cover plate, and the bottom plate is generally made of fiberglass board or bakelite, not metal materials, otherwise it will be hot after the furnace, and no one will dare to take it.

Bakelite is made of imported glass fiber material, stainless steel material and carbon fiber board (synthetic stone).

High temperature resistance 350 degrees without deformation.

FR4 materials can be used for small yields, and synthetic stone materials can be used for large yields.

Details plus specific materials and uses should be analyzed in detail.

Most of the soldered circuit boards are analyzed in detail about failure analysis and reliability analysis.

There are many reasons for continuous welding, and too much flux is also one of them. Retrofit the spray device, and you're good to go!

Our professionally developed motor sprayer can save 30%-50% flux!

Power saving: no gas source (no gas compressor, reduce investment cost, can be used when connected to the power supply);

Time-saving (the nozzle does not need to adjust the air pressure, which eliminates the defect of unstable flow caused by air pressure changes, reduces the manual adjustment process, and improves the work efficiency and product qualification rate);

Material saving (spray balance can meet the production requirements without large flow, because the FLUX sprayer on the market sprays more flux, so it needs a larger pressure, and the reason for spraying more is that FLUX is easy to block the nozzle, resulting in unstable spray volume, which needs to be solved with larger pressure and more flux), saving about 30% of flux on average;

Clean (no gas compressor is used, which eliminates the pollution of air pressure and moisture, improves the brightness and fullness of the solder joints of the circuit plate and the clean layout, improves the work efficiency and product qualification rate, and improves the utilization rate of the machine);

Environmentally friendly (the right amount is uniform, no odor, the dosage is easy to control, the natural volatilization of flux is reduced, and the smoke during dip soldering is reduced);

Stable and durable (using imported components, all stainless steel shell, corrosion resistance, beautiful and practical).

Apply high-temperature adhesive tape before wave soldering.
