hi all,ive been trying without any luck to get the attached schematic onto a pcb layout ready to print without any luck so far,would it be cheeky of me to ask if someone can do it for me,im on a time limit with it,all resistors are 2 watt and the first two transistirs are to39 footprints,the blockind diode is mounted off board,cheers paul,btw the pc board i have is 7cm x 10. |
| m3vuv:
forgot to sat the relay will be mounted offboard as well as the 2n3055. |

* Is the "blockind" diode the 100A diode at the top? * I don't see that any of the resistors need to be bigger than 1/2W. * Is this your design? It's not good to put two diodes in parallel. * What is the coil? What size is it? * What is the capacitor? Radial/Axial, hole spacing? * The parallel resistors 4K7 and 680 could be combined into single resistors. * Is the max voltage 24V? Is this AC or DC? Is the fuse off-board? * Mounting hole locations and size. * How do you intend to connect all the off-board parts. Connectors, terminal strips, solder to trough hole, etc? |

What is exactly your problem? It shouldn't be an issue on a double sided board. Is your pcb single sided? There's too many details missing ... At least specify all the footprints for the components :palm: :-// |
| MarkF:
Your circuit does not look right. But, here is half of the circuit without the needed information. PCB 70x70mm The relay could fit in the upper right corner (depending on size). |
