Some doctors said. If you inhale the smoke when you are doing soldering, it's like you are having a tattoo in your lungs after you inhaled it.

Try to touch your Soldering Iron. If it's hot, then it's working.

Yes, so it is advisable for everyone to wear facemask while soldering.

You are soldering your wires to connect them.

Maybe a minute? But it depends on what your outlet's current output, the higher the Ampere, the faster it will heat.

What kind of solder should I use with delicate materials such as wires and metals?

Fri Aug 24, 2018 8:43 pm

What is the chemical composition of a solder? What makes them have a low-melting point?

Fri Aug 24, 2018 8:46 pm

Hello! I have read the whole forum and I would like to add another question about fluxes. Is a flux similar to a brazing paste? If not, how do you differintiate them? Thank you

For many applications, the flux included in the core of the solder wire is sufficient. However, there are several applications where additional flux is extremely beneficial, such as surface-mount soldering and desoldering. In all cases, the best flux to use is the least acidic (least aggressive) flux that will work on the oxide on the components and result in a good solder bond.

Rosin Flux
Some of the oldest types of flux are based off pine sap—refined and purified—called rosin. Rosin flux is still used today, but modern rosin flux blends different fluxes to optimize its performance.

Organic Acid Flux
One of the more common fluxes is water-soluble organic acid flux. Common weak acids are used in organic acid flux, including citric, lactic and stearic acids. The weak organic acids are combined with solvents like isopropyl alcohol and water.

I have a follow-up question for this, How long is the shelf-life of a flux? When is it applicable to use?
