Introduction
When working with hardware, it is often necessary to make changes during the design process or repair procedures. While these tasks may seem simple at first glance, they can get very complicated. In this post, we will present a few chemicals from our arsenal that we believe are crucial to have on hand for physical hardware modifications, based on our experience with the situations we faced with.
Situations
Cleaning
Isopropyl alcohol (>99.8%) and Ethanol (95-96%) are crucial for cleaning PCBs, especially when dealing with stubborn contaminants like black dirt, flux residue, or other grime. Their effectiveness in dissolving residues and evaporating quickly without leaving traces makes them essential tools for maintaining clean and functional circuits.
Soldering
When soldering, it is a good idea to use this kind of Solder paste mixed with some kind of Flux gel.
Desoldering
We encountered situations where it seemed impossible to desolder a component. No matter how much we increased the temperature, the component didn’t want to move a bit. In such cases, this one can save the day:
