Unknown chip that looks blown

[Gsc1ugs]

Hi

Trying to find out what this chip is that looks like its cooked, its off a snapon scanner that packed up and someone with sharp eyes spotted this please see pic

Why don’t you de-solder that chip and take a photo that’s in focus at different angles we need to see the markings on the chip.
If you cannot de-solder then you will not be able to solder a replacement chip.

Well i managed get a great shot - see pics, other pics are what its out of, snapon scanner that stopped working

 

[danadak]

Is that a hole blown out of chip top or something you can scrape off to get
a good pic of the markings ?

Hello,

I see the chip has 10 pins.
There are some microcontrollers with 10 pins.
You can likely not replace the microcontroller, as it likely has a custom program running on it.

WOW truely blown

As Bertus said, if it is a micro-controller, you would have no idea of the firmware that has been programmed into it
That's a real killer for repairs like this

 

[Gsc1ugs]

So its not repairable?

 

[danadak]

Contact manufacturer and see if you can get a replacement part ?

Is sun still in business or absorbed by another company ?

Any groups.io support site for obsolete sun stuff ?

Any mechanics sites you can post on looking for info ?

 

[poormystic]

Electronics manufacturers feel pressure to sell.
Accordingly they use bespoke components, and make the equipment hard to fix.
If not all manufacturers are like that then some must go broke fast.

(I hear that if huge money is involved, the equipment is not only impossible to fix without the manufacturer's blessing but requires a constant supply of new parts and/or software fit to pay 3 mortgages.)


Why do you want to fix it? Is it the cost of getting a new one?

 

[Gsc1ugs]

Yes the cost is considerable - this unit was £350 ive contacted snapon waiting for reply

 

[Martaine2005]

Snapon, at least with hand tools carries a lifetime guarantee.
Surely a mechanics scan tool should be covered too?

 

[Gsc1ugs]

You would think so, im still waiting for contact

 

[Martaine2005]

I had a Snapon lorry parked near my work. He was in a café. I went inside to see him and he met me afterwards. He rebuilt my 1978 3/4” ratchet there and then.
Free of course! What a super star.

 

[Gsc1ugs]

Ok spoke to snapon rep who said the mem stick at the back is used to update the unit so hes saying, for a £1 chip is said worth the gamble, is this chip easy remove because i think ive found one

 

[Gsc1ugs]

Is this the chip ?

[bertus]

Hello,

Yes, that is the correct chip.
It says 6714 in the datasheet as on the chip.

Is it worth a go and is this chip easy remove ?

 

[Martaine2005]

Is it worth a go ?

Absolutely not. Snapon has a lifetime guarantee. Fight it!!.

If it fails, Snapon’s guarantee will filter through their buyers and hopefully STOP their over priced rubbish.

As a side note. A YouTube channel checks the consistency of strength and durability of Snapon. It is shamelessly advertising £300 screwdriver bits when a £24 bigger set was stronger. Absolutely disgusting.

See post #2
If this is the first time you’ve ever soldered or de-soldered a (SMD)surface mount electronic component, it would probably be the last time as well if you’re not a hobbyist so it would not be worth it. This is what you will need.
It cost $35 US plus solder paste, a pair of tweezers or forceps & the component itself. It’s a hot air gun. should only take a novice five seconds to remove & another five
Seconds to align and solder in place.

If contacting (snap on)fails, They do sell kits for practicing desoldering and soldering SMD /SMT components.
Once you’re confident.
With Rosin flux applied to the pins & heat the area with the heat gun & gently lift the component with tweezers.
Then with at least 90% isopropyl alcohol, clean the rosin flux residue.
Add your solder paste sparingly orientate the component with the tweezers and apply heat.
Shop around it would cost you less than $60 US for everything which is much less than the value you stated.
