Q:Can aluminum solder be used without soldering flux?

There are a lot of aluminum tin answers online, but can not fundamentally solve the problem of aluminum oxide at. Is not high enough to solder iron temperature, there are non professionals that use direct welding method and rosin, the most close to the aluminum solder is using flux solder, also provide pictures to prove how good the effect of solder, flux is actually used to weld several months before solder oxidation quality directly effect of aluminum products.No soldering flux, no flux, no harmful gas, and a clean working environment. The utility model can effectively prevent bubbles and pinholes, does not need cleaning procedures after welding, reduces the bad rate, reduces the welding time and improves the welding quality.Penetration soldering aluminum to improve sealing.

Q:Eldest brother, please tell me: steel slag pressure welding special flux, commonly known as "drug residue"?.Do you have a friend who can give me a detailed information about the dregs?!In addition, some say that automatic welding flux is called "drug residue". Please help me explain! ~ urgentOh, yes, I asked a steel worker today. What he told me is that the official name is "vertical welding flux", commonly known as "slag", which is used for automatic welding, that is, plastic welding, but I still can not find information about the residue of the medicine. However, I found a lot of slag data, there is no residue of drugsYour elder brother can help me, I will appreciate it!

Yes, that's what they call "slag". That's epoxy. They're right. But it's too complicated. It's not necessary

Q:Because of my article is aluminum solid core, it is not with the flux? Is there any need to add it?I am the aluminum tube in the fridge and welded to the aluminum tube

What is your key wire? Do you use flux or flux? Most solid wires are made of flux

Q:What are the rosin flux formulas?

There are many types of flux, different types, and no ingredients inside

Q:The core wire twisting wire peeling after soldering, using disposable flux, lead-free solder, tin products place several days will be black, what is the problem? How to solve?

Where the tin is stained, the product is oxidized,Abnormal handling of the product: re - oxidize the product to the tinIf the terminal is to solve this problem, only professional wire flux will be changed

Q:How about Jin Yuancheng's soldering flux and bath water?

The company had not heard of, as for welding plate washer water use, and how to be used to know, and any one of the flux, and the washing water can not be used directly, but to see not suitable for good, suitable for use, not for bad.

Q:In the product after SMT, the performance test is no problem, but to the customer after two or three months or more, that one of the key chip resistor 0603 package resistance becomes smaller and smaller from 24K to about 21K, I put all the lines around this resistance are disconnected, found resistance or 21K, then I the resistance from the board removed, the resistance is not bad, or 24K, use high-powered magnifying glass, the intermediate SMD package with flux residue and more, is not because of the flux and the residues have internal resistance, request the master answer!

Look at your soldering flux type and content. Should the alcohol base be better?

Q:What's the soldering flux inside the solder wire?

Rosin come, if it will splash is too large if rosin, rosin too much not only will splash and residue of black objects, strong solder can be free for you to solve this kind of problem

Q:When I was in training, I was glued to every eye. Why is it a big chunk when it's welded?.

A large piece of solder is expected to point to the solder jointGeneral understanding, the activity of flux is not enough, two is the temperature setting, temperature 250 degrees as the standard, taking into account the dip, instantaneous temperature loss, it is set to 280-300 degrees.

Q:Urgently!!! The plating of nickel plating meets the soldering flux when soldering. The reaction result in the surface of the electroplated parts is pale yellow and black. How can I deal with this problem effectively and make the electroplated parts come back to its original appearance? Online results

It's definitely not going to be the way it is. It's the next thing to do, not the first time
