DIY Printed Circuit Board PCB Making HHO PWM Part #1

[zomgwtfbbqbagel]

so how does this stop the whole board from being conductive?

if you printer paper is thin and semi transparent then i guess that would work just as well as film, may take a few more mins to develop but should still produce same results.

[LauxHawk]

Do you need to use laser for this method?

[cristian3131]

Can I print the artwork with the HP inkjet ? Or it will just spill all over the transparent film ?

[X2YeZCAMCNC]

no to sure I have never tried that way

[pat60606]

@cristian3131 Use Vellum paper, available from any stationary store. UV Light passes through it just as well as it does transparancies. You can also get there, a felt tipped pen you can use to touch up any place where the ink is a little thin!!!

[X2YeZCAMCNC]

@pat60606 I use the transpariency because it works. Not interested in changing the method. I don't need to use a felt tip marker because the blacks are always solid.

@cristian3131 you cant use any inkjet printer because it uses ink, you should use laser printer and photocopy machine because it uses toner and toner can melt using ordinary iron, you can print it on inkjet and copy it in your photocopy machine!

These videos are great. I wonder, can this process be used for a (high) power amplifier PCB? Let's say a 200w x2 @ 8ohm/1000w x2@ 1.5 ohm continuous power direct coupled amplifier? Feed +75/-75 volts. I'm guessing either no, or the traces would have to be wide etc.

Thanks

[X2YeZCAMCNC]

Yes you could make any kind of electronic device with through hole or surface mount components

[djhesit8]

@PureBrew1 take in calculation your amperage...

[birdysim55]

So that print of the circuit board just fell down from the sky? Why cant anyone tell how to do this from start to finish?

Everybody has a print.

You have to start with a drawing program.

[X2YeZCAMCNC]

I made the artwork on the computer and had it printed at UPS Store or you could get done at any copy shop.

If the same artwork PDF was printed on glossy inkjet paper, I could have done toner transfer but this way I get a better copper trace (no pits) and I can make many boards from this one artwork.

Thanks for your comments.

You can run laser grade transparency sheets in a laser printer and do the same as you are now paying someone else to do.

[X2YeZCAMCNC]

Do you have a four color laser printer? Staples and UPS Store does...there is a big difference if you try it.

[rhblakeman]

Since I repair printers for a living I have all kinds of printers - inkjet, solvent ink, color and BW lasers, solid ink, etc but if you are happy with what you get at the copy place then by all means - my intent was to make note that you only need a BW laser and transparency sheets to do them yourself with the photosensitive copper. If you print black on a 4 color laser it still uses black toner only though.

[X2YeZCAMCNC]

OK you may want to check on that!

[RetroRepair]

You can use a cheap old laser printer to do the same job on transparancies.

[dumyyyyyy]

too complicate! the toner transfer method works better and much cheap! And the results are very good!

[armed23ogm]

What brand PCB did you use?

[X2YeZCAMCNC]

Injectorall or MG Chemicals 609

[redrooster424]

Thank you for the vid, was curious to see if you have tried adding the photoresist to plain copper clad and if so what have you found, in name brands, easy to work with? thanks again and keep up the great work, would love to see the components added and soldered to your boards.

[X2YeZCAMCNC]

In my early year of making PC boards I did use LENLINE BLUE PC pens and still have a dozen of them. Never use anymore. I can layout a board, burn to disc, go to UPS store and print on transparency, come home and within a hour or so have my project built on a quality home brew printed circuit board. Would not do it any other way.

[ayearofholidays]

Great video! Could you please list the names and brands of each of the liquids that you use? Also is the light in the beginning UV? Thanks!

[X2YeZCAMCNC]

The lamp is UV sun tanning lamp from early 80's

275W Sylvania bulb

Will try to list the chemicals in video info section

Thanks for your comments. Give me a rating if you can.
