That's excellent work pasanlaksiri. How did you achieve the component layout artwork, using silkscreen?

well i dunno how pasanlaksiri does it. But one way is that u print silk screen/component layout on self adhesive label and voila.
or other way is use hot iron technique (read toner transfer) also works but not so neat and clean but it's safe for the circuit. Moist (air) -> paper label or plastique is not nice combination with electronics.

it have been almost 10 yrs. when i first time try it.

Hmm no links actually. I learn it from some local dude

But did u see this video

Nope no thinners. There is special inks for screen printing.

And im using this UV sensitive chemical to make screens ( Autotype PLUS 1 SR )

So let me see if I get this right...

Your using the technique in the video to create the screen itself of your PCB and Silk
The question I think most of us have is what kind of ink are you using to do the resist on the copper side?
What technique are you using to do actual etching?

My questions to you would be

1) Are you silk screening both sides and then etching?
2) Once your done with a screen can you remove the burnt emulsion and make a new screen on it?
3) For someone new who wanted to do screening what kind of cost are you looking at for the screen, emulsion, tools (Squeegee and Emulsion spreader) and ink? (Am I missing any supplies?

I'm impressed with the quality of your copper etching.  Looks top notch to me.

I've never been able to produce quality like that at home.  What kind of trace widths do you think you can get and what kind of spacing between pads?

Nice work!

Cheers

i did the screen printing earlier with cheaper PVC glossy ink (Rs. 45 per 200 gms) without thinner. this scheme also worked fine if you have all fixtures like table etc.


After seeing your post i enquired about special ink available for pcb works, cost are as follows and also i am mentioning cost for all other tems required for geting started in screen printing ( Cost in Indian Currency)

1. PCB ink for making tracks etc - Rs. 375 / Kg
2. Thinner for above ink (Thiner is always required) - Rs 260 / litre
3. Silk creen print ink - Rs. 610 / Kg
4. Thinner for above is same as a mentioned in sr 2
5. 12 inch x 14 inch screen cost - Rs. 150 (Screen can be reused)
6. Screen coating sollutin - Rs. 90 / litre
7. Film - Rs. 45 / meter (210 mm wide)
8. Decoating sollution - Rs. 5 (powder to be mixed with 1 litre water)
9. Squeezee - Approx Rs 20 per ince length
10. PVC glossy ink only - Rs. 45 per 200 gms
11. 500 Watts halgen bulb - Rs. 20
12. Frame holder for hlding halogen lamp - Rs. 70
13. glass and table - Approx Rs. 200
14. Good quality water sprinkler (ne we can see in hair cutting shop) - Rs. 45

Dont use PVC inks. It will dry quickly but its paint layer is very thin, easily it can be peel off.
