Yes you are 100% right and also we should use flux for lead free soldering
as it is assign for high temprature

For sure solder paste accelerate the melting of the original solder joints like we use to melt hard point specially earth points

excellent hint but also with marker use a led lamp very cheap if you use usb one

But the main problem you make it look very easy-i still find using the hot air gun much easier for me

Please always share with us ,forum members own plenty of Jovy RE 7500
we could discus to make all work easy there are many tips

1- Fast process ( Most of users use it now )
2- proper helping tools ( flux,reflective tape and solder paste )
3- Removing glued ic's ( Most safe tool for this process without damaged any other glued components)

Such post here this section assign for such support also all members could help through their chat programmers (MSN,ICQ or Sonork)

I believe also support @ Jovy-sys.com is very friendly and fast and helpful

YOU ARE WELCOME

Dear Raheeeeb,

Thanks for all the videos you have posted on your site. They are very helpful. One suggestion i have is for each video, do let the others know at what temperatures you finish the process, eg in reballing, desoldering, mounting. From the videos some temperatures are easily understandable, but once the camera is focussed away from the display one doesn't know at wha specific temperature you complete the jobs. Also please mention the height of the heater as per your experience.

Best regards!

I have used these temparatures

For IC removal from 37 to 80 C use preheater in park mode. Between 80 and 90 C pull IR head roun to normal mode then swithch on overheater ir in fast reflow to 180 C then remove IC as in video. Troble is that temp varies du to solder type ie if it is lead free or not that is probably why Raheeeb has omitted temparatures. Little more temp applies to reballing 190 for lead and 240 for lead free. I think you need to use some discretion of heater hight. The lower the temp you want the higher the heater hight the higer the temp you want the lower the heater hight. In other words heater hight and temp are negativly corrilated.

Dear friends, could someone explain to me how BGA placement is done?

Obviously i dont have much experience on that.

I am experimenting with the rework station at the moment and want to remove an underfilled chip and then refit it on board.

I can remove the bga and reball it.

My first problem is how to clean the mess on the pcb.
Second, how do u align the bga with pcb. I would need 2 ir beams, no? Do u locate the centre on both the chip and board?

Raheeeeb thanks ur videos are very helpful, but in the
Easy Uem By jovy RE-7500.wmv the step of actually alligning and placing the chip on the right position is skipped

sorry for the silly questions

It is not silly (ask whatever in this technical support section even you did not have machine from Forum offer )

aligning is the next video

My Friend before Jovy machine arrived we all used to work with hotair and that time it was working fine, but at the same time as the technology is changing and to make yourself more professional and more acurate we should use more professinal tools like Jovy machine. I have tornado machine but you cannot compare Jovy with tornado or hotair these are different machines, near future i will place my jovy order for sure and at the end i would like to say that if you learn some thing from a experienced person like Raheeeeb you should always respect you should never write "RUBBISH" kind of words remember my friend every single day its a new learning experience.

We all are here to share our experience.

Keep it up
