Btw. can you see any solder in the bottom sides via drills right under the chip? Looks like they haven't soldered the thermal pad to the board.


if i understand you right....no there are no extra holes to hold the chip down.
just the big ones for the heat sink to push the chip down to the pcb.


can you show a correct imlementation with a nice pic?...please...thx
 
What i mean is, that i can't see any through-soaked solder at the vias coming from the powerpad at the other topside.

Hi!

I am in the process of building a six channel TPA3255 amplifier (three "chinese" tpa3255 modules with three switch mode supplies).

I would like to use a speaker protection and turn on delay module.
I have some UPC1237 stereo protection modules at hand, however, they use a common ground between the left and right channels.

Is that ok for the bridged stereo TPA3255 module, or will I have to use seperate modules for each channel?

Thank you,

Arndt
