scratch BPA200 pcb lay out

[digi01]

the PCB lay out is a pretty crazy DIY things for me

this is my BPA200 projects,the chips +/- rail and ground track has not finished yet,any suggestions??

the sch is based on the original BPA200 article,use DC serv.and the amp pcb is not including the push stage.

 

[carlosfm]

No need to use servos.

 

[digi01]

mmm...
because those 3886 chips need to leave certain distance.it happens that there is space of serv parts on the boards,I put it.

I think it's wise to provide the board space for serv circuit.If you do not like the BPA200 work at serv mode,just leave the serv chip socket empty.

optmize version,including input buffer.
the pdf file show top and silk layer

My matrix power supply boards,for BPA200.
a couple of typical unregulated bipolar power supply,and big caps of supply reservoir capacitance for each supply voltage rail.

the PCB board can mounting 300/400mil pins,44mm(max) diameter caps.

Do you not have ANY psu decoupling caps on the mainboard?

 

[digi01]

The main board was not set up any bypass caps.I have leave a series holes near the chips for mounting the mother rails of power supply.

Hey digi01-

Will you be offering these boards for sale too?

I have the perfect chassis for a pair!

rabstg,thank you for your interest.I am not very satisfied with the layout.this project has been stopped temporarily.if there are a lot of interested,I will continue revising it and offering PCB.

Hi Zang-

Ok.. If you do persue this project and eventually have boards made please send me a set and a bill.

I would wish view your pcb for BPA200

Do you have images of your BPA 200 pcb project, please?

 

[Kravchenko_Audio]

Me to!!

Definitely interested in how this turns out! Your design may finally get me off my butt and build one of these.

[digi01]

thank you

It is early when I saw BPA-200_Application_Note of NS,I had a good mind to design a pcb board for myselfs interest.Later NS released AN1192 article again,but there is still not a official layout available.So I think this layout of DIY to have realistic meaning.

my project is total base on these two articles of NS.the BOM list is same.

Bridge/Parallel Amplifier (BPA-200) Documentation

AN1192

At the same time I will thank DIYAUDIO, this LAYOUT revised is a New Year present that I gave DIYAUDIO.

I have not manufacture the board.I accept pre-order(over 20PCBs)then I will work them out.

the attached photo is the final board silk layer,double side board,160x33mm.you can build BA100/PA100/BPA200 AMP.

if you have interest,can drop me a mail.

I have got the boards a moment ago

the upper thing of the photo is a chinese pencil the PCB size is 160x33mm.
