holy________!!!

Ok, I have finally got round to building the first version of the clone theory I designed a PCB for, so after a process of etching the board..found I forgot to flip it...etched again.......looks good...get to populating it....I usually do resistors first, then caps, then Trans, then IC's.......right

I have EVERYTHING soldered to the board except for the IC's, its taken me two days in what little spare time I have..........I come in from work tonight, start solderign in the IC's first the duals..soldered str8 to board....then 2 sockets for the CD4047 and the MN3007......ok all looks goood at this point.

I go to ease in the CD4047 and a confused look dawns on my face and curiosity hits me..........................Why are there 2 free pins at the top?

I laid out the circuit for a 16 pin IC when the CD4047 is 14 pin!!1



ARRRGGGHHHH!!!!

I have to start again.... :cry:  :cry:  :cry:  :cry:  :cry:      


and to top it all off, the only cd4047 I have one of the IC "legs" is broken it broke when I took it out of the socket......

:roll:


sorry for the long post need to vent to some people who will understand my frustration.

I'm sorry, I can't relate. NOT!  :wink:

[Arno van der Heijden]

Maybe you can do a quick hack to the pcb so you don't have to start all over again....

I have been known to do that.  :lol:

[zachary vex]

just make a little socket/perfboard daughterboard that re-routes the misaligned pins and solder it into the 16 pin holes.

[nelson]

The Board *just* fits in a 1590BB, if I were to add the daughter board it wouldnt fit.....I did spend 10 minutes working out how I could hack the existing traces to match the chip....would need a bunch of little jumpers under the board which would raise the level of the board too high and would stop me fitting offboard connections.....

I am just going to start again i have a day off tommorow and nothing to do......I will solder a new leg on the CD4047 and etch the corrected board....


Thanks for the understanding and tips guys....


I am thinking of creating a sort of "photo Diary" to post to the forum of an entire build from scratch....never really seen it done before.....seen parts of builds done before...

I wish I had nothing to do on my "day off"!  :lol:
Ain't it fun designing swiss watches?!  :wink:

[aaronkessman]

what about floating the daughter board over the existing board, or up against one side of the enclosure? hate to see all that work gone.

jumper wires, anything?

[WildMountain]

Man, I really feel sorry for you. I'm sure a lot of guys here, including me (in my short life as a pedal builder), have been in this sort of situation.
I hope you can fix it with with Arno and Zachary's suggestions, I hope all is not lost for your project.
Good luck!

not enough depth or length when all the switches/pots etc are in box, for the daughter board at all...

So I am in for a day of Vodka Music, guitar and electronics tommorow......and a few others.....its not as if I have nothing to do....i am just doing things *I want* to do


it makes a change

[Paul Marossy]

The first time that I designed a PCB layout, I mirrored the layout, mistakenly thinking that I had to do that for it to iron on correctly. I proceeded to etch the board, drill it and all that stuff, only to realize that the layout shouldn't have been mirrored! After I kicked myself in the rear, I realized that I could still use the PCB. So, I had this PCB with all of the components on one side and the opamp on the other.  :oops:  :lol:

[nelson]

I will document the build from blank to finished article....if all goes to plan (never happen) and it works, ZeroTheHero has offered to host the layout on his site.

[nelson]

here is the old project file I did, notice the 16 pin CD4047

my poor topic........ :lol:

[Paul Perry (Frostwave)]

I would solder wires to each of the chip legs, then to where they should go.

[petemoore]

if you laid insulation down, then perf a socket, lay that on it's back on the board where resistors are, maybe make one 'scrunch over' by replacing it, I don't see so can't say ...it wouldn't be much higher than an electrolytic.
 I 'wedged' a 4558 in a DS-1, I though it couldn't be done.

[nelson]

Arggghh when correctign my layout, I just noticed the traces around the fet are wrong!!!

I would need to have started again anyway.

Makes me wonder what else is wrong...... :roll:

You guys get days off?  I must be in the wrong line of work!
