yes.My current hurdle.
Searching the library for parts.
My relay does not exist in the library. Do I build one and add it?
it will make a difference on how close to other components the IC can be placed.My IC's are in sockets. I dont think that makes a difference.
There are pcb symbols named "DISC04' and "DIOD04" in the discrete library that can be used for all 1/4 resistors and 1N4148 diodes. The pads are spaced 0.400" apart. I typically use 0.200 pad spacing for 0.1u-0.47u caps, but you'll need to check the datasheet for the caps you use.I'm using the discrete library to select caps, diodes, and resistors but I'm not sure if they are physically the right size. Mainly the caps. They are all different sizes.
You'll need to choose a part and look at its datasheet. You'll be working with close tolerances, so you'll need to check the footprint on the datasheet against the library footprint you use.I'm using "header" to indicate the inputs but some of my pins are 2.54mm apart and others are 5mm. Not sure how to be sure that the pins i've selected are the correct dimensions.
Thank you very much. I am making some progress.Some advice, if you have to make circuit changes, always change the schematic and forward the change
These are the connectors (input / output) for power, fan, buzzer, and signal in.You'll need to choose a part and look at its datasheet
make sure the discrete library is enabledFor some reason the "wizard" did not include any of the resistors.
Make the change at the schematic. if you don’t like the result you can ctl-z to reverse the change. Then forward the change to the PCB when ready.If I replace the 8, 14, and 16 pin IC'S with the sockets will I need to remap all the connections? I assume I make these changes in the pcb and not the schematic.
My library files do not have sockets or DIP's I do not have a prolib. i have a pcb lib but no DIP's only DIL's. Generic IC'sMake the change at the schematic. if you don’t like the result you can ctl-z to reverse the change.
That's ok...as long as you are aware there will be a socket and account for the space when placing parts.My library files do not have sockets or DIP's I do not have a prolib. i have a pcb lib but no DIP's only DIL's. Generic IC's
What I can do is
1) don't place components too close to the IC
2) edit the component and put a 1mm rectangle around it.
Sorry....i don't know what "SPLICE" is.Components that did not merge with the PCB wiz were SPLICE. The wiz does not like SPLICE. i changed them to R 0.25W 5% MCF (470k) from the resistor library.
Most pin layouts (footprints) on parts are designed to fit on a 0.100 inch grid. So...if you use mm then set the PCB grid to 2.54mm (=0.100 inch). If you don't do this, then pins will be difficult to connect with traces when routing traces on the PCB. I use "inches'" or "mils" but it doesn't matter as long as you manage the grid correctly.To help with sizing I put a grid on the PCB and set it to 2.5mm. So when i add a component i can see that it is the correct size as the ones i have.
I am having difficulty locating the variable pot.
If I am in the library manager I can see it but it is not available when selecting components. Ive tried many things. Re-indexing, copy, move, make my own with the wiz. They just won't show.The "prolib" is one of the many libraries that comes with DSPCB, so you probably don't have it enabled
Cool.I find that from the pcb tab I can alter a component and it applies my changes to all matching items. So I changed the sizes of the resistor from the discrete library and the 3pin trimmer from another. It looks good. The center pin on the trimmer is off by .5mm and the resistor the same. So far the board layout is 85x55mm. Thats just 5mm from my original. I can toy with it and probably get it to 80x50 but its not critical.
Good news. All thoes errors are gone.
I'd like to be sure that the net router did things correctly but that may be difficult.
Did you mean to you uploaded files?Files for project with extra circuits removed
I removed the external fan/buzzer circuityou mean to you uploaded files
I do not have that but I did aquire one from Loader. CD4013BEE4.I think there is an exiting schematic symbol "DTYPE03" you can use
You can "fix" a track (lock it in place) so that the router doesn't affect the track.I removed the external fan/buzzer circuit
I do not have that but I did aquire one from Loader. CD4013BEE4.
I removed the auto routing, changed the component, then re ran the auto router. It changed a bit. I think everytime i run that feature the routing is different.
HERE is my final file. i hope. ive cleaned it up a bunch. the rule checker is upset about overlapping screens but it visually looks ok to me. Can you recommend a developer for this PCB i need 20. 50x80mmI never use the autorouter because they never do a good job of routing
