Excellent! Very good work!

Do you have the schematic and board diagram available?

[richhagen]

Nice looking board!  Rich Hagen

[ibedonc]

Yes , send me a email , will not post it here because of scc3 copyrite

ibedonc at star-c dot com

also it is done in eagle cad

heatsink from dead PC smps  , you can get transformer cores and heatsinks , maybe some

resistors , I would not trust the big caps

I have a power supply that as ghurd would say 'made magic smoke' the other day, I was looking at scalping the heatsinks for a FET in a low voltage disconnect I am putting together for my 48 volt system for some auxilliary lighting.  My PCB's not going to look nearly as neat as yours though, I'm still using magic markers to mask and ferric chloride to etch.  Rich Hagen

My PCB's not going to look nearly as neat as yours though, I'm still using magic markers to mask and ferric chloride to etch.  

One of the electronics mags here in Australia was suggesting a new technique a couple of years ago:  print your PCB layout in REVERSE on a laser printer (or photocopy it), then place the toner side against your blank PCB and use a hot clothes iron to transfer the image.  You'll probably not be able to peel the paper away dry, so dunk it into some warm water to soften it for a while until you can.  Then etch with FeCl2 as usual.

I haven't tried this yet myself, but it sounds like it'd be a lot faster and neater than the magic marker technique (not that there's anything wrong with that!) ;-)

I use Eagle Cad to print on EPSON PHOTO paper in a HP 6L laser then I iron on the pcboard , even have made double sided boards

[commanda]

Better than an iron is a hot laminator. I've got one at work with adjustable heat & speed. The rollers are movable & spring-loaded, so the pcb thickness is no problem.

are they expenive ?

I setup a the very simple 48v lighting controller layout in illustrator, and reversed the image in photoshop, now I can't wait to pick up some photo paper, print it out on the laser printer at work and give this method a try.  Rich Hagen

tips ::  make sure you clean the board with 0000 steel wool and then with alcohol

DO NOT Touch the cleaned surface and iron it on till the back of the paper turns lite brown rub it good with the iron , put it in cool water then change  it warm (100f)

let it soak it will start to bubble . the brand of paper makes a big difference

Epson glossy Photo works best for me almost falls off in minutes of soaking

even the big boards I am doing

Kodak not good

use a sharpie to fill pin holes

with this process I can layout a board and have it working in a even

it takes a few tries to get the hang of it

also set printer to darkest print and highest quailty

[commanda]

Dunno. Probably. Been looking to buy one like it for myself for a while without any luck.

I did, at one stage, use the heated rollers out of a laser printer. Built a little controller to drive the stepper motor, and control the heat to the lamp. Worked great till the temperature controller failed. Oh well. It was quick & dirty, with an el-cheapo relay switching the lamp. The relay contacts burned shut. I'll use an SCR next time.

Circuit make magic smoke Bad.

More bigger heat sink good.

Less bigger watts good too.

Plastic or rubber burning smell means more fastter running good.
