So Chris what do you intend to use this for? Not something I would put my hand into for long . Heaps of illumination
Curing false teeth repairs ;D , or PCBs?
Or erasing old UV eprom chips?
Lefty
And here I was thinking it was a Tanning bed for dolls..
Maybe frying ants? Checking to make sure his counterfeit money passes?
I feel like my eyes are going to get damaged just looking at the pictures of those things.. lol I really hope you're using some eye protection when you're looking into those.
Photosenthising (think i spelled it right). for making pcbs. the toner transfer method kinda sucks and plus the laminate sheets that are printed with a laser printer are reusable ;).
Well, good luck with this then. I've heard many people say they aren't successful with light-exposure pcbs, but I hope you figure it out :). Let us know how it goes.
ill post pics when i get one made... i got alot of copper clad boards off ebay for cheap. and so far so good on the test strip
need a new drill bit... one i got messed up the board startin over again... least got plenty play with
success today :). now I just need drain cleaner to take the photoresist off.
The materials I use are:
My light box built from an instructable on instructables. Any uv around the rated nm required to expose the image of the laminate should work . I generally smoke a cigarete when im exposing the light (approx 4 mins). It can do double sided boards compared to the 50 dollar mg chemicals little setup which can only expose 1 single side at a time.
Cost: 50-60 bux but if you can scavenge the mdf, router stuff, glass, etc it'll be way cheaper.
3M negative laminate film (bought off ebay) comes with developer. Mix developmer 1/2 tsp to 1 cup warm water. Instructions come with it.
Cost: 20 bux
Laminator - to laminate negative film onto cleaned copper clad board
Cost: I won an auction and paid 8 bux for a like new laminator that heats to 300 degree f.
Etching tank I made out of lexan, fish tank bubbler & tubing. Takes about 10-15 min to etch maybe less but the times vary on how much you are etching.
Cost: 15 bucks
Clear overhead projector paper. Its awesome if you got a layout made you can re-use your design over and over. (I've noticed 3M's is best to use since toner adhears and doesnt leave any if at all missing dpis)
Cost: about 50 bux for a whole box or around 50-75 cents if the office supply store will do this for you.
Copper etchant: Don't use floric chloride, its messy, expensive, and takes longer to etch. What I do is mix 2 parts hydrogen peroxide (I got it at walgreens for 1 dollar; also bought at the local farmacy, wal-mart, drug store, etc) to 1 part muriatic acid.. any hardware store should have I got 1 quart for like maybe 9 bux. This stuff is reusable and it dilutes with water very well so its not as bad as an enviromental hazard as floric chloride.
Cost: 10 bux
Copper clad board off ebay single sided 12 pieces 4x6
Cost: 9 bux. Not bad for 12 boards compared to radio shacks prices of around 8 bux for just 2 double sided boards.
The whole setup I spent about 100 bucks, but if you have any of the pieces then this price can be quite cheaper :).
Edit: If you guys need any help or info let me know. Making your own boards let alone your own circuits is quite an accomplishment and price isnt bad at all. You can use an inkjet printer with the clear paper just make sure its rated for inkjet (its rough on one side, smooth on other),
You can also use UV tubes from a facial sun. And a home built box to hold it all in.
