Why is an INFRA machine needed?
•	What more can it do than a hot air?
•	First since 2006 June all PCB’s made all over the world must be lead free PCB’s
•	The melting temperature for lead free solder is 225 °C
•	Also if you have a PCB with lead free solder wire and if you try using hot air to repair it the PCB tracks can go bad.
•	So there is no other choice but to use INFRA heating station

How does this infra work?
•	The Infra rework consists of two units; one is the Pre Heater and the second one is a Hand Held unit.
•	The Pre Heater is used as a base on which the PCB is placed and kept in place with the help of small magnetic foot.
•	The Pre Heater is used to preheat the PCB up to a suitable temperature from the lower side. Approx mate temperature for preheat is 100 degrees which will display on the unit 300 in meter in the preheater
•	Once the PCB is preheated to the required temperature the Hand Held unit is used to heat the required part to a higher temperature (sufficient to melt the solder) and the required part can be removed.
•	Another new part can be also be fixed in the same way – after proper application of flux

A couple of TIPS
•	The hand held unit should not be used at maximum temperature. The peak temperatures are quite high and can damage the PCB.
•	Moreover different types of IC’s require different working temperatures depending upon size, if it is glued and various similar factors.
