Tips and Tricks & F.A.Q.


Here we will try to bundle some of the most important Information about the TORNADO INFRA Tools

FIRST STEPS in USING THE TORNADO INFRA

"Please read the atached pdf document to get a better idea how to use the tool.

http://www.gsm-tool.com/Infrabasics.pdf

Also - FIRST take some time and old -bad pcb and play with the infra station on them, untill you get the practical skills to use it on the phones. Then you will see all ok."

regards,
Gobi

Problem:
On few handel units, the Power supply unit is working ok, but the Handel is NOT HEATING


Solution:
So - the small problem is now identified: On few pieces, INSIDE THE HANDEL, 1 of the 2 connectors that connects the wires from the Heating element to the siliconic-cable was not crimped well. Jost use a crimp tool to fix that and all will be ok.

However, before you open the handel, please ask your reseller if he allows it, or he repair it for you, so you don't void the warranty.

regards,
Gobi

Some More Tips ...

Verry important:
http:///vbb/showpo...07&postcount=1
There you will find the first steps for using this tool.

To melt to soldering material you need over 200 degree Celsius - for "old"=nonROHS PCB.s and a bigger temperature for "new" PCB's - the lead free ones i mean.


You can hardly get some universal settings pattern since every PCB will behave different; the one will need more energy and the other less in order to melt the solder on the working area. This is why you need the Thermometer there.
In the package you have received a Thermometer --> use it, by fixing the thermocouple element on the area where you are working--> then you can see the REAL TEMPERATURE on the working area, and adjust the preheater and the handheld in order to obtain the needed temperature there.


1 - Preheater
It is used to heat the PCB from DOWNSIDE to a temperature UNDER the melting point of the soldering material. After the PCB area is preheated, you will have to apply less energy (compared with the situation if you would not have preheater) to the PCB Upper part, with the Handheld unit - so it will work faster, the "stress" for the PCB and the components will be also less.
SO - the temperature ON THE PCB, produced by the preheater should be somewhere 100 - 200 Celsius, DEPENDING on the technology (ROHS) used for the PCB. If you overheat, then the solder will melt and the components will fall down from the downside of the pcb.

On some Preheater it is used for adjustment just one potentiometer, on some others it is a programable control unit - both constructive alternatives doing actually the same job.
The control unit has 2 displays:
- big red display showing the REAL TEMPERATURE of the coil(heating element) inside
- smaller, green display - showing the Temperature of the coil - that you are setting
There are 4 buttons on the programmer: It is really verry easy and intuitive to work with them.

2 - On the Handheld Unit, there is one Potentiometer for adjustment and one display showing a scale (not Celsius).

As sayed - the Thermometer on the PCB is the one who give you the information if you need more "power" from the handheld or not for one or other PCB.

At the end: MOST IMPORTANT: Take your time to make FIRST some testings on old PCB's untill you get the necessary experience and skills.
Use more and use less power; don't care if you may also "toast" some old NON-working PCB's during the tests. It is verry important to learn what the tool can do, in order to be able to apply later the right working parameters on the phones PCB's.
Then you can start using your new Tool also for the repair works on the phones, without dammaging them.

regards,
Gobi

Using the Thermometer

The thermometer is used to monitor the actual temperature of the PCB. The temperature changes with regards to heat and time when heating element radiates infrared heat. The preheater can radiates heat around 100°C,and the handheld heater up to maximum of 800°C(but dont try to use this when reworking as it may toast/damage your pcb).

Just place the thermometer's end wire near the reworked IC or a metal plate near to it.

For better and safe results it is always recommended to use the thermometer when reworking.
