Mechanic V4B45 soldering paste is a special type of low-melting soldering paste (tin in the form of a paste) intended for soldering electronic components, i.e. SMD, BGA, e.g. in repair processes. Due to the very low melting point of exactly 138 ° C, the use of the paste in this process allows you to perform complex repairs (e.g. placing the CPU on an iPhone) without exposing the other components of the phone to damage that may result from the need to reach 217 ° C in the lead-free soldering process.
