INFARED IC HEATER OVEN, is it good?

[MC Harami]

im interested in purchasing this machine which looks like an grey shape oven in which u insert the PCB into for 5 minutes, it gets heated then u can remove SMD/BGA and then u put a new piece on and then it will put it back on the PCB!
IS this machinery a good tool to use and does it always work when u put a new BGA/SMD?
Also what are the prices for these machines?
Please find the picture for it below!

[spectrum]

I have one, but I am not very impressed.

[Scaramouche]

More information please!!! Why are you not impressed? What can't it do? Why is it a worthless purchase?

:)

[leosedf]

It doesn't look fine to me. I prefer my hot air with my hand. the best combination.
How to move the board after heating??? if you move it you will move also many parts on the phone

[Scaramouche]

hehehe hand is good. I dream of buying a proffesional model like a Sniper II which features automatic solder & desolder, split system optical alignment of BGA PC control, etc, etc.. Nice to dream.,,,,

China crap is just that.. CRAP...

[leosedf]

dreams are good. everyone has them, me also. But stick to the real thing. You can control the situation better with your hand :)

[hakumatsuo]

above pictureof IC heater u posted, is NET501. contact me for price.
www.aoyue.com to check AOYUE710 which is best for Ic heater.

@Scaramouche
I did not say it was a worthless purchase.
What I meant is, it has not performed anything extra-ordinary the other equipment such as Ultrasonic, Heat guns and jigs wouldn't do.

But my main problem is to localise the heat in a small area, where component needs be removed. Any idea on how to do this?

[Scaramouche]

Spectrum, i have these questions.

1) Can it heat the ENTIRE PCB to the point where its possible to remove ANY IC immedietly? or does it cool down so quckly when you eject the phone from the over it teras BGA pads?

2) Does it damage Epoxy Glued IC like CPU, UEM, etc, ie makes solder bubble from the sides? or is it safe to use?

[Scaramouche]

Well, i dream to have proffesional workshop similar to Nokia Level 3 / 4. I started from china jig, and slowly 1 by 1 i acquire top quality equipment like genuine MJS, Cadex, HP 8922. So the best way is to start off with cheap tools & simply invest when money comes in.

It's sure that the quality is really not the same than chinesse products but prices of this stuff aren't really the same too !

Just click on attachements and enjoy ;)

I have not tried it on removing components.
Because I am scared of heating up the entire surface area of the board.
And thats why I asked, if there is a method of isolating areas.

@Scaramouche.
I am still yet to get the Memory card for my HP 8922M
Searching for it frantically.
Because without this card, this piece of equipment is useless.
Can anybody out there HELP?

And by the way whats an MJS?
What does it do? Can you give me a link
Thx

[Scaramouche]

Spectrum, iam still looking. as soon as one comes up at a good price, i will buy it for you.

[MC Harami]

yeh so guys overall i need a machine to change UEM chips but im not very good at soldering manually! i have tried afew times but still i think im abit dodgy! Any suggestions?

[Scaramouche]

YES, i have a suggestion!!!

An auto-soldering machine usually costs more than $12000 US, so if you have this sort of cash go ahead & buy iy, you will be very impressed with the results :)

However if you dont have such money, you simply must learn how to solder properly. Take some old phones like 3210 or 3310, and practice, practice, practice. it will be difficult & frustrating, but you will soon become profficient.

[MC Harami]

u know what thats what im gonna do, im gonna buy myslef a re-work station n just practice until i get it right!
I have some experience in soldering i just need perfection!
Thank u

[Scaramouche]

Make sure you buy a digital temperatre control station, like a 850D

[MC Harami]

where can i view this 850D? i was thinking of a AOYUE SMD REWORK STATION 968

[Scaramouche]

850D is a generic type - its a clone of the Hakko 850D. So many china companies have their "850D" type soldering iron.

The 968 will do the job well too.

[spectrum]

Spectrum, iam still looking. as soon as one comes up at a good price, i will buy it for you.

I am ready to pay what is offered. Afterall it will not be more expensive than what the local Agilent rep charged and a wrong stuff was still delivered!

[Titcher]

Looks good. . . . . .

[Mansoor]

Hi Max B were can i buy the machine you hard displayed above and at how much can it cost me it is my first time tro se that type of machine

[zaymoun]

hi evrybody,
i need a crack for the new qualcomm's Qctest cait , if somebody can help plz contact me
I'am ready to pay for it , thx .

reply at zaymoun@yahoo.fr

if there is something semilar that can treat with wcdma phone ,I take also, it's really urgent and important so guys bring out some ideas

[leosedf]

???

I think you are posting on a wrong threat

[hakika]

Can anyone advise how much this costs?

[hakumatsuo]

this one 10Kg, very expensive.
not the right one for a new guy.

[leosedf]

around 700$ dollar.
Not recomended for a bit unexperienced. Stick to the old 850D
:D

@MC Harami

Not the sort of statement you want to be making on a public forum, since such activities are illegal in the UK.

Anyway, bga replacement in general, best thing to help is practice. Get some 3310 boards etc and practice removing the ics etc, there are some guides around or go on a repair course. There are a few courses within the UK that provide training for bga repairs.

[YourPhone]

Do you know of any in Sus***? JIC is so far for me

[MC Harami]

what statement u talking about mate??

[mobymaster]

yeh so guys overall i need a machine to change UEM chips but im not very good at soldering manually! i have tried afew times but still i think im abit dodgy! Any suggestions?


The one refering to UEM changing.

[YourPhone]

what statement u talking about mate??
sorry i didnt press quote button the remark was in respect of mobymasters comment "there are some guides around or go on a repair course. There are a few courses within the UK that provide training for bga repairs" the best I have found is JIC but they are miles from me. Does anyone know of any places in East Sus***?

[mobymaster]

@YourPhone

JIC are probably the closest to you, excell is even further.

2 spectrum's question of pointing heat 2 wards particular IC r PA;s, I use a small piece of card board covering the entire board cut only in the place where the ic is located so that heat is focussed only to the ic.In this way I remove ic' PA &any thing that's on board.

[spectrum]

Good idea!
Any other good heat-isolating material?

[GsMen]

proper way to solder is to slowly heat up the board. You may also heat up the entire board, its no problem. Also extra "underheating" is better, cause youre going to spread the heat.

The biggest fault "hand" solder man make is they want to be fast. They heat up a small part of the board to 300 degrees and want to pick up the IC within 20 seconds.

Take your time to slowly heat the board, if you dont do that, your board will heat up and cool down to fast and it will bend resulting in cracks in various layers.

Any machine (professional rework station like weller wqb, martin, airvac etc) wil need approx 2 minutes to gently heat up board on top and on bottom, before you can lift up the IC, than it needs at least another minute to gently cool down. The advantage of this kind of equipment is that it have solder profiles, so you cannot make mistake of "soldering to hot" or "soldering to fast"

regarding the IC oven. I think people that sell it DONT know what it was intend for. Its not made to put in entire boards. If you read many service manuals you will learn nokia uses it to baking ic's like PA. Some parts must be baked for mor than 24 hours (but I have doubt any service center uses it)

[Motoroller]

anyone can advise about R&S GSM mobile testers? Where to buy it cheaper, maybe second hand, with proper calibration and with all necessary seals?

[::Yasir::]

Can't understand?? You are experienced! so, which equipments did you find best in desoldering surface mounted IC's in PCB??

[arif_tual]

Thanks GsMen !
That's make i realize why sometimes i change COBBA several time with new one but still CONTACT SERVICE. May be they are " well done cooked = COBBA STEAK " ???? He...hee thanks you've give me a candle.
