Braze welding of electronic components
In welding processes of electronic components with PTH or SMD techniques, a rise in the melting temperature of leadfree alloys accelerates oxidation of the alloy leading to greater defects and waste. InerSOL E technology injects nitrogen into the crucible in wave soldering machines and in the pre-heating and melting areas in furnaces to control the amount of oxygen in the melting areas of the welding alloy.
The inert gas is injected through sprinkler systems designed and made on the basis of the type of SMD furnace or the wave soldering machine and the Crucible on which they must be installed to optimise the inertisation of the environment reducing the consumption of nitrogen to a minimum. An inert atmosphere makes it possible to:
- reduce joint defects and waste formation
- reduce costs thanks to lower consumption of lead-free alloy, crucible maintenance and a reduction of the time taken to correct defects;
- reduce the number of short-circuits and solder balls;
- obtain shinier soldering
