Nothing to ask guys, sorry, have only to tell.
So, today had to learn a DFN tablet soldering process. Damn tricky, but as technologies progress, must have to go along em.
Thus the biggest problem is that they arent solderable by normal methods.
They have a thermal pad in the middle, what must be well soldered without of any touch possibility.
They have a numerous contact feets covered completely by body, thus untouchable.
First I just applied an air solder (hot air blower) and failed of course. Tablet was dead after procedure.
So, after a bit reading how the things must be done I applied the thermoregulator to the 150 C, wait an about 5...10 seconds and then set the temperature above to 260 C, keep a 4...5 seconds and Voila!.
So, the 150 regime gives the time to tablet to warm up mildly to avoid the crystall thermal shock.
That is extra important.
Im happy with the result.
Use this experience if count it useful.
Thats all. How radio code says to say, Over! and then Out!.
