Programmer Upa

[matech]

I was thinking of tiling a UPA to my GQ-4X

a strange curiosity?: I just bought a caliper ?m to read the SOIC8 without desoldering, but now I have doubts on the actual reliability? this programming system.

It is reliable?
It is more reliable with a UPA compared with the GQ?

thanks

for reading, you always have to unsolder
otherwise, how do you correct a reading done wrong?

Hello
No, no you have to unsolder, some eeprom you can llere with the caliper, and the other not.
You will only need to asicurartti here the reading is good.

in fact, it was my doubt!

but since I see that these calipers little ones around, I have the imnpressione that many use them without even unsolder....

it always depends on what you need to do,
second, what do you do if a reading is made badly, you notice it immediately
according to what you do instead, you notice it after that maybe the machine nn more
they are certainly comfortable, but you must always be ready and equipped to unsolder

Here, then, such as the eeprom are read with the caliper?

I simply try to read most times and see if the check ? and always the same. But this does not protect you from being able to corrupt the data, but...

you better get to unsolder always, read with the caliper of the chip soldered on the board many times ? busted.

I see so
at least at the beginning you make of the readings is with the caliper that can be seen
then when you're reading done well by a hurt, you can also read directly only with the caliper
p.s. to me pocp time ago and asked for a reading that seemed to be well made, but it has left a string, all ff ff ff ff ff
and was that where there was code key

on purpose to avoid problems of the kind I prefer to unsolder always.
