i have to get other paper for the exposure when i expose say 10 or 15 seconds too long all small traces are gone.
the transparancies, even 2 on top do not block uv light enough.

all vias done with a simple copper wire.

Looks good for a home made board. Well done.

Now get that thing all soldered up and tested.

Sometimes, when you are working with prototypes, it makes alot of sense to stuff only one channel and test.

wise advice, should have thought about that but i am over excited .
everything is almost on the board.
spent 15 minutes looking for a 10ohm resistor just to find out it wasnt in stock and it would be delivered later.
this delivery was 4 weeks ago and i still dont have the resistor.
for now i will settle with 2*20ohm.

everything on the board accept the ad834s and the smb sockets.



not using the beads yet instead of the 4.7ohm but i do have them.

decoupling= 1nf-10nf-100nf-1uf-6.8uf-tant all cogs.

Can i see the inside diameter, the Jack is about 1/8 diameter.

here it is.

[dvh99]

im afraid that is too small.
are you sure that is an smb.
the inside diameter is 5 to 6mm.

yours is 3.75mm

[dvh99]

my connector has to go 5mm over the socket.

Its the link you gave me in my PM, J520-ND is the number on the package sticker.

From the drawing and what i see here it look like the diameter of the teflon insert is 2.08 mm, so the round teflon cylinder inside your plug
must be 2.08 mm.

Yep same part number and data sheet.. PN: 131-3701-621 I am trying to see which plug they suggest for it.

here is the interactive catalog.

i should have had this one but what i do not understand is that my connector isnt right, it is a smb.
