Hello all,I'm working on a small electronic circuit myself here ---->>>
http://www.elektor.com/magazines/200...r.531629.lynkx

I just have three question if anyone can help
1:I have 3 boxheader components here supplied by "spc multicomp",it says on the board that pin 10 and pin 1 of K1,K2,K3 should be opposite each other but i can't find a datasheet for the component I have so I don't know which pin is which,any ideas??

2:B1 and B2 on the board.I think the "+" pin of B1 and B2 is the goes on the bottom left on the board.Is this right?

3:T1BD139:Looking directly down on the board I think it placed pin 1 first,then pin 2 then pin 3,is this right?

Sorry i'm never very good at this so any help is appreciated

The pin numbers are printed on the board.
K1 is rotated but follows the same pin layout
for K2 and K3: Pin 1 is the upper right-most pin then they go counter-clockwise. pin 10 is lower right-most pin, below pin 1

5  4  3  2  1
6  7  8  9 10

The pin 1 and 10 are printed on the board, so you should be able to follow from there.

 

Ya I got that just the thing thats confusing me are the pins on the boxheader component
Like on this one http://www.equinox-tech.com/Products/details.asp?ID=359
(thats the only data sheet i could find)
It says the that pin2 is opposite pin1 but on my board I need pin 10 to be opposite pin1 if ya get my drift

 

Ahh... Are you wiring the header? Because it doesn't care, as long as the wires are in the proper order for the PCB.

O right,I thought the pins had to match up and what not.
One problem down,two to go....
