Solder flux storage in a nail polish jar

Nail polish jars are useful for storing solder flux for daily use. The brush is resistant to all kinds of chemicals.

Applying minimal tin to solder tip with solder balls

With solder wire it is difficult to apply a very small amount of tin to a solder tip, that's easier with solder balls:

Small raised SMD work table

With small parts such as SMD you have to sit with your eyes close to the work. To be able to do this comfortably, I made a small raised work table of wood:

Double lens loupe for SMD

I use a loupe with 10x magnification. But keep in mind: the loupe must have a double lens to see the small SMD components well. Unfortunately, almost all loupes use just one lens.

High temperature grease for Hakko soldering irons

To prevent seizing of the nozzle screw, apply high temperature grease to the thread:

You can use Hakko 800-026 Anti Seize Lubricant or just any high temperature fauset grease.

Micro Soldering Microscope

I came across an interesting website Microsoldering that sells all kinds of tools and stuff needed to repair smartphones. For example, here is a microscope:

Tweezers

Small SMD parts such as the 0402 require tweezers with a curved pointed tip:
