flux
It takes a long time and is used many times. such
flux
Preservation is different from those large production lines that use one bottle, several bottles or even dozens of bottles at a time.
One:
flux
Basic principles of use and storage
The basic principle is to have as little contact with air as possible, and the less the better.
flux
After long-term exposure to air, it will cause
flux
The ratio of oxidation and flux is unbalanced. The consequences are:
flux
There are crusts, lumps, refractories and a lot of tin balls.
Two: a bottle.
flux
Precautions for repeated use
1: The opening hours should be as short as possible.
The opening time is as short as possible, and it is enough to take it out on duty.
flux
Immediately after that, the inner cover should be covered. Don't use a little, always open the lid or always open the lid.
2: Cover the lid.
take out
flux
Immediately after that, cover the inner cover, press it hard, and squeeze out the cover and.
flux
Between all the air, make the inner cover and
flux
Close contact. After ensuring that the inner cover is tightened, tighten the outer cover.
3: Take out
flux
Print as soon as possible
unlike
flux
It is necessary to carry out printing as soon as possible. The printing work should be continuous, and the PCB boards to be processed on duty should be printed in one breath, and placed flat on the workbench waiting for the SMD components. Do not stop printing.
4. Redundancy that has been removed
flux
Processing of
After all the printing is finished, the rest
flux
It should be recycled to a special recycling bottle as soon as possible and stored in isolation from the air according to the precautions (2). Don't put the rest
flux
Put the unused ones back.
flux
In the bottle! In case "a bad piece of meat spoils a pot". So I'm taking it.
flux
Estimate the offset as accurately as possible.
flux
Take as much as you need.
Step 5 Deal with the problem
If it appears.
flux
Never stir when the surface crust becomes hard! ! It is necessary to thoroughly remove crusts and lumps, among others.
flux
Before the official use, we should do a test to see how the trial effect is. If not, it will have to be scrapped.
