Recommended Soldering Tips for Micro-Soldering

Microsoldering

The recommended tip size for micro-soldering is one that matches the width of the micro-component (A), or (A-0.1)mm, as shown in the image below. Tips that are slightly larger than "A" can be used if it does not come into contact with the adjacent components. 

Width of micro components

Once the size has been determined, the various applicable shapes below can be selected, depending on your preferences. However, there may be instances where problems occur, such as cracking on multiple ceramic capacitors due to the thermal stress of soldering and insufficient heating on multi-layer printed wiring boards (PWBs). To avoid such issues, use a Nitrogen (N2) gas soldering iron to pre-heat before soldering.
