Hi, 

 

I have a uspcb but am a little concerned about shielding, internally between the power and data lines, and externally - a simple heatshrink will not block anything from being picked up. What is your take on this? 

 

Thanks. 

The PC board in the USPCB is a 4 layer board. Layer 2and layer 4 are solid shield planes. The VBUS, GND and data wires are on layer 3 which sits between the shield planes on layer 2 and 4, thus no external metal shell is needed, the embedded traces are fully shielded by the shield planes.

 

On layer 3 there are wide shield traces in between the data pair and the VBUS/GND traces. The result is the data wires sit inside a "tunnel" of shielding blocking external interference and interference from the VBUS/GND wires.

 

The connectors themselves are shielded and the signals via down to layer3 right at the connectors.

 

The result is that the design is quite well shielded and doesn't need external shielding. All an external metal shield would do is triple the price.

 

Now if everybody WANTS to pay triple the price for a fancy CNC machined shell just so it looks nicer, we can certainly do that, but it goes against our philosophy of the best performance for the lowest cost.

+1 for a longer length option, for ability to use between streamers and DACs

Can you guys get together and define what you mean by "longer", and please specify what the length refers to ie "tip to tip" or some other reference.

 

I'm not guaranteeing this will happen soon, I am working VERY hard on the etherREGEN. Things like this just add to the wait time.
