I think I've killed my Flexdriver.

[LBPark]

I have soldered Micro Flexdriver for set the ampere to 500mA-1.5A.

and wires were also soldered.

And after that I was in contact with the diode for the test.

However, the diode did not respond.:cryyy:
(The diode is a new one.)

This was my first soldering though.

but I thought I did it well....what the problem:thinking:

Overheating the board or what else?

 

[foulmist]

can you post a detailed photo of your driver setup and solderings :beer:

 

[jander6442]

did you short out the caps before soldering the diode?

 

[LBPark]

sure I did
but I didn't soldering the wire with diode

I wrote this post in mobile so I can't upload the pic

the soldering is look bad but I think connecting is well done.

you mean you operated the driver without load?

 

[LBPark]

o <- diode
||
ㅁ <- driver
/ \
1.2v aa x3

looks like this

Is this wrong connection?

What he is asking is did you power the driver and then connect the diode. If so you for sure have killed your diode and possibly the driver as well. Also if you are not using soldered connections to your diode you again have probably killed the diode.:cryyy:

Any loss of connection to the diode even for a microsecond will charge the cap and then discharge into the diode killing it.:yabbem:

How can I check the diode is dead?

I think it's dead but there is hope isn't it?:cryyy:

I think it's dead but there is hope isn't it?:cryyy:

if you have a constant current PSU you could try connecting it directly to the diode. Be Sure that it is off first

you mean this?

How should I set?

I don't have much knowledge about this
I am really hard to make a laser.

just thank you for your help.

No. Thats a multimeter. A very handy tool to have as well.

Power Supply Unit, Something like this >>>

I got it

thank you very much:thanks:
