Compact inline hybrid selective soldering machine FLEX-i2

Manufacturer E-therm
Model Flex-i2


The number of working modules (total) - 4 pieces;

Fluxing module - 1 piece;

Preheating module - 1 piece.

Principle of operation:

1. The PCB sequentially moves through operations (fluxing, preheating, soldering)
2. The PCB enters the fluxing zone, stops
3. Fluxing of the programmed solder points
4. The PCB enters the preheating zone, stops
5. The infrared pre-heating zone is switched on.
6. The PCB enters the soldering zone, stops
7. Soldering programmed soldering points
8. The PCB gets out of the machine
