Stacked PCB connector ideas ?

[Jan Dupont]

I have new solid state amp in mind, and just from looking at the block diagram, I can see that I (due to size limitation) need to stack the VAS stage PCB on top of the Output section PCB.

The distance between the stacked PCBs must be 15-20mm (0.6-7.9"). The signals going through the connector are mixed control signals, low Current audio and power signals (max 1A).

Is there out there who knows of some good audio "PCB to PCB" connectors ? I have thought of just making wire connections, but would like the easyness of the connector type connection.

Any help appreciated.
Thanks in advance 🙂

Hi friend Jan

I have used many times those pin strips gold plated. Simply you can broke each pin from the strip to use it seperately. I don't know if you want the pcbs will be pluged between them so as can seperated easily. Me, i preffer to solder the pins in each pcb for the purpose to avoid any parasitic capacitance. You know what i mean.
Also, take a look in Farnell site, there are gold plated Molex as i remembered.
Also in "Selectronic.FR" site, there are many types of gold plated connectors and other goods for audio use. It is a nice store.

I agree with the pins.... I buy them on long strips or a few cents...
and of course you get the strips in female too...

They come in a variety of pitches and lengths and you even get angled ones.

Hello fotios 😉

I do know these gold plated pin headers (use them a lot for jumper purposes), however I havn't came across ones that are long enough (20mm). However the short pin headers may be used, if the receiption is a vertical connector like on the attached picture (however I do not need this big space between PCBs.
Thanks for the link 😉

Thanks Nordic 😉

Anyone know if these are good and where to get these?

 

[Nordic]

I'll grab a few for you from the shop when I go on Monday... They definatly have them in longer versions, I think the long one is about an inch... It has two plastic strips to keep the pins seperated over the full lenght, instead of just the one strip at the base...

Waith they must be even longer, as I found a small piece from the medium sized pins... and they are 22mm

P.S. super neat pins in your picture...

Sometimes the breadth of their catalog can be confusing, but Samtec specializes in this stuff, and will usually ship small quantities quickly.

Thanks Nordic 😉

Anyone knows the Farnell or RS part no. ?
I have browsed their websites for hours, but didn't find the long ones that Nordic presented.

Thanks for the tip, Conrad 😉

I get those from a small retailer... would hate to know what RS charges for them... as you could see from the picture the pins are completely untarnished after 2 years, even just lying in a little drawer... (I live by the sea)... I remember them being quite cheap... like cents I think....

 

[Jan Dupont]

Yes they look just great, Nordic 😉

I just hate to make a PCB layout with "hard to get" components...
It could nice if they could be purchased locally later 😉

 

[Nordic]

I will let you know what they cost... I think you could buy a lifetime supply for less than $10...

 

[Jan Dupont]

That would be nice. Thanks Nordic 😉

Just found this at RS;

I sent you a message this morning...

I can get 21 and 35mm lenght, they come in snapable strips of 40
and are about .33EUR in single strips and .25EUR each in 100 strips (4000 pins).

RS calls it WIRE WRAP HEADERS, and charge 10 times that...

 

[Jan Dupont]

Thank you, Nordic 🙂

I have replied 😉

Nordic, i've sent you email... I'm also interested with the 35mm headers.. thanks
