PCB based invert 3886 chipamp assembly and comments

[digi01]

this thread is build for talking about 3886inv gainclone and assembling.any suggestion is welcomed.
feel free to post your finished gc.

Series PCB design tips:
AN-1192
BPA200 Application Note
LM3886 DATA SHEET
LM338 regulator
LT108* DATA SHEET
DRV134 DATA SHEET
and,much information comes from Chip Amps forum,thanks everybody

Pcb boards detail:
BLD driver
Regulaotr power supply
LM3886 INV AMP
The size of these three PCBs is totally the same,I like the layout style of tight & compact pattern.I think this way is mentality of designing of GAINCARD too.
I have not designed the unregulated power supply PCB.
If you want to assemble a PCB based unregulator igc,there are two very good unregulator pcb design:
BrianGT's rectifier PCB
peranders ultra fast rectifier bridge
bigparsnip's ultra fast rectifier bridge

3886igc and regulator psu connections.

The file releasing attached zip package includes 3886igc +regulator+BLDdriver,gerber output files and nc drill output files.
for gerber viewer,
I recommend CAMtastic,the CAMtastic DXP free viewer supports a wide range of import formats, including ODB++ and Gerber viewer...

Going to be printed tonight and put into book : O ) thanks digi.


I also need to email you about some ideas and questions.

10x for sharing this with us !

to assemble an integrated stereo amp with regulator power supply.
step by step pic
first,for 3886inv boards.
because it is a regulated gainclone,so small caps is all right
finally,I use 4x 330uf/50V silmic caps for decoupling.

[digi01]

all resistors is KOA SMD for gain setting.

[digi01]

second,for regulator PCB.
pic,screw the liner regulaotr on the heatsink first.

[digi01]

then solder the big caps finally.the big caps that I used is nichicon 6800uf/50V.
