Member: 29669 Status: Offline Thanks Meter: 1 | preheater and ... manual I have just got full Tornado Infra Station. There was no manual inside package. So here I have a few questions : -what temperature is shown on preheater and on main hand with lamp, I mean F(arenhait) or C(elsius) -I think that little manual for preheater is needed for programing specially here are some buttons and two indicators and diodes and buttons -it would be great if we got some instructions about settings of preheater and hnd lamp ( I mean time , temperature, and distance between handlamp and PCMB) wbr diStefano |

Member: 6328 Status: Offline Thanks Meter: 3,595 | 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 |

The new tornado infra is using infrared heating, it directly heats and melt the lead on ic for rework purposes. NO more ****n out small ic's for there's no air used unlike those hotair stations. For best and faster rework it is recommended NOT to use nozzle so that all infrared heat can dissipate directly to the reworked ic. In the new batch of handheld stations, the nozzles were not included so as not to confuse users on how to use it. regards, ren Last edited by ren77; 08-04-2007 at 06:30. Reason: spelling | |

Thanks Meter: 1,350 | Hi REN77 I am asking you for perfect work of PA replacing , in hot airgun we heat the PA for fixing underside of the pcb but in most cases PA become faulty, so I ask you is this irstation replace PA without damage ? can we directly heat PA via this irstation? pl give me more details on it |

In working with PA, the idea is to apply less heat and always apply good flux to shorten the melting point of the lead. Last edited by ren77; 08-09-2007 at 03:36. | |
