Homebrew PCBs

Hi,

This is something I have done a few times using LineArt in Photoshop to get
a clear black/white image. At the time I didn't have toner paper and used
printer paper sprayed with Transparantiser and coated PCB boards. It worked
but was a lot of messing.

Regards,

Terry


| Hi all,
|
| Didn't see any discussion on this topic in past posts, so I thought
| I'd throw this out to the group...
|
| I am trying to reproduce a circuit board for a very old arcade game
| from 1975.  Its an old style pitch and bat game, so the electronics
| are fairly simple, but the board is huge (approx 13x19") with about
| 100 TTL Logic chips and various resistors/capactors.  Double
| sided...  This board is no longer available and I have not been able
| to locate a board for quite some time...  I was able to borrow a
| board from a fellow collector, but it is only on-loan.  I also have
| the schematics...
|
| My question to the group:  Does this sound like a resonable process
| to reproduce this board:
|
| 1) Remove all components from board
| 2) Scan in both sides (double sided board)
| 3) Touch up artwork and output to transfer paper
| 4) Transfer images to copper clad board
| 5) Etch, drill, populate...
|
| Is this the process most of you would follow to reproduce a board?
| Or am I missing an easier process?  I actually thought about re-
| designing the board a little smaller, but I cannot afford the cost of
| an auto-routing software package to do a board of that size.
|
| Any thoughts or suggestions?
| Thanks!
|
| Tony
