Problem & Solution
Micro-soldering and BGA reballing on modern smartphone logic boards require precise thermal control to avoid damaging heat-sensitive integrated circuits (ICs) and multi-layer PCBs.
Using general-purpose high-temperature or non-eutectic solder formulas can lead to thermal stress, board warping, or cold solder joints due to uneven melting ranges.
The MECHANIC 183℃ XGZ40 Solder Paste addresses this challenge by utilizing an Sn63/Pb37 alloy matrix with a sharp eutectic melting point at 183℃. Combined with built-in flux, it simplifies precise component reflow and BGA stencil application during phone repair tasks.
Who Is It For?
Designed for smartphone logic board repair technicians, micro-soldering professionals, and BGA reballing specialists who require a predictable 183℃ melting solder paste.
It is also suitable for hardware hobbyists working on fine-pitch SMD micro-electronics rework where Sn63/Pb37 solder characteristics are preferred.
