Hi thunder,

If the equipment has a name and number on it try to Google it and you might find a manual for it. Or go to the manufacturer’s homepage and you will find the necessary info. 8)

Thunder, since this is an International site and many, perhaps most members, do not use English as their first language, perhaps it would be easier for others to know what you are saying if you do not use slang or abbreviated synonyms and numbers for words. You might get more help with requests. Just a suggestion.

Thanks,

Hi Thunder,

I've been using China made Hot-Air Rework Station AEOLUS brand model 850C to do some SMT/BGA soldering and desoldering..
There is NO PERFECT setting for this since it is dependent on:
1. Line Voltage
2. Nature of Soldering (with groundplanes, heatsinked?)
3. Precised setting can only be determined by experience  ;D

As a rule of thumb, I start at 5 for AIR and  5.5 for HEATER

Good luck

Rhonn

high kasa miko,
look !  tell me how should be the position of the heat gun , should i start from the corner of chipset or apply it to all sides? and the other question is till wut tempreture the ic can resist?
thanks!!!!!!!!!!!!!!!!!!!!!

Don't direct the heat ing the MIDDLE of the chip..if it is a BGA type..use a good quality flux and rotate the nozzle around the side dont stay in one position..
Heat only the the pins of the chip..
