[@SwitchAndLever]

If you print the laser toner onto either glossy magazine paper (cheap thin glossy ad magazines work great), or onto glossy inkjet paper, getting it to adhere to the metal is much less time sensitive, you can leave it for days no problem before laminating if you wish, and it comes off from the paper much more easily once you soak it in water. I've done this quite a few times etching plaques and they come out perfectly. Printing directly on copy paper is a bit of a hit and miss though, and the structure of the paper can impart in the toner and make it not stick as well to the metal. I have a video on this very process as well.

[@MrCarlsonsLab]

Tried this, and it works ok. The paper in this video was the result of "a lot" of research, and works much better than magazine paper. (at least the magazine paper I tried.) I prototype a lot. Thanks for sharing your experience.

[@SwitchAndLever]

@@MrCarlsonsLab different strokes for different folks I guess. I too prototype a lot 😄 Copy paper has never led to any great success for me. Ultimately whenever I used that I got bad adherence to the metal and had to do lots of touch-ups with a Sharpie to fill in where the toner didn't stick. Best all around result was glossy inkjet paper in the laser printer, but since that's a bit expensive glossy magazine paper is I'd say 90% as good. I guess the principle is that the less the toner adheres to the paper it's printed on the better it will stick to the metal 🙂 Have you tried the etching films which you expose with UV and then wash off the unexposed film? While a bit more finicky I know a lot of people making custom circuit boards who swear by it.

[@ixamraxi]

@@SwitchAndLever I believe he uses some kind of glossy photo paper, not copy paper. There is some paper specifically designed for the pcb transfer method, though I have not tried it personally. If it works well, it would be a reasonable cost depending on the volume and size of boards a person makes: www.amazon.com/Circuit-Board-Thermal-Transfer-Special/dp/B01CGRL2G0 I have a laser cutter at home, which I have used it to do circuit boards by spray painting the board with an even coating of black paint, then using the laser to burn away everything except the traces. This method works, but can be finicky depending on paint, residue, cleaning method, etc. I have also purchased some 'Photosensitive Dry Film' for PCB production from eBay that I intend to try, not sure if you've seen that stuff but it seems like an interesting method. Basically it lets you apply a photo-resist film to any board. I am still experimenting to see which method I like best, I expect I will settle on whichever provides the best work vs results vs cost ratio. :P

[@dalemettee1147]

Watching you complete these PCB's reminds me of the company I used to work for. The bottleneck was ordering and receiving the boards in a timely fashion. It got so bad that they decided to buy a close by PCB manufacturer. The process was the same only on a much bigger scale. Positives were produced in the photographer's dept. and 'shot' on the raw boards, developed and plated in rather large tanks hung in the solutions and then processed. A design change could be turned around in a couple of days instead of a couple weeks. Big difference. A simple change could scrap a whole trashcan full of old boards. Typical government expenses and over runs, plenty of over runs. Good job Paul!

I use Diptrace for artwork and schematics. Cheap (actually free for small boards) and it outputs all the data a fab house needs. I find Bay Area Circuits is a good source for small board quantities. I have no financial ties to either of these. I first built boards in the 60's by manual taping the artwork, getting a negative made, exposing the board coated with Kodak Photo Resist, and then etching with ferric chloride (that part hasn't changed!) Now, I'd rather let someone else deal with the chemicals plus the boards come back conformal coating which is hard to do at home.

Wow! Nice work. I used to do this back in the 1970's. All I had was an etch-resist pen. Nice to see Ferric Chloride is still used. My hand drawn circuits were crude but effective for the simple projects I did.

[@hestheMaster]

Bought a printed circuit maker kit from Radio Shack 40 years ago. It had a large plastic tank which doubled as a case to hold the equipment and the Ferrous Chloride bottle. Funny how I actually forgotten ( when I was seventeen ) what I made but had to do with a model train diesel horn. The kit had very precise black self adhesive tabs for making pads for IC legs (used a LM555 timer IC )which after etching was off a little on two of eight places!

[@Murgoh]

I did the etch-resist pen ("Dalo"-brand) thing in elementary school back in the 80:s and did some still in the 2007 or something like that when building guitar pedals. Works just great for through hole components where great precision or fine lines are not needed. I still have the big pickle jar of ferric chloride somewhere, I've not used it for over a decade though so might as well get rid of it.

Excellent! This video gave a ‘blast-from-the-past’ as back in the late 1980’s to early 1990’s, I used the toner-transfer method, using a clothes iron, then vinegar and water for removing the paper, along with finger rubbing for the course, then a brush for the finer paper fuzz removal. The thinner the paper as tracing paper, the easier for removing. Ferric Chloride enchant and yes it stains everything and open fumes will corrode nearby medal tools when warm, if not sealed up. I never used the tinning solution but tinned manually with solder soaked desoldering braid and it was not an easy job as the chemical way. Wonderful video Mr Carlson, it surely brought back pleasant old memories. Also, a fish tank air bubblier helps with etching agitation if doing lots of boards. Additionally, Muriatic-Acid and Hydrogen-Peroxide is said to be a decedent enchant but I’ve only used it once when was out of Ferric Chloride and yes, it did work, only taking longer to etch but gave a good ending result.

We did this differently - way back in to 80's. We designed the layouts with tape and dots on plastic film back then. We used double-sided precoated resist board. First expose one side in the blacklight box, this created an image on the resist that was clear enough to align with. We'd drill through the location points then use them to align and expose the reverse side. Rinse the exposed resist off with caustic. We'd then wet one side with ferric chloride and float the board on the etch. Rinse, flip, repeat. Clean resist with caustic soda. Drill the board. Created DS processor boards like this - I did a few Z80 projects this way.

[@mike94560]

I have done this several times. I would add a step. Run board through laminator 2 times to get it hot before attempting the transfer. Then put your print on it and run it through 10x. This way the toner transfers on the first pass through and holds things in place. It kind of sticks the print to the board. Otherwise it doesn't do that on the first pass. And you can have misalignment problems. Or broken prints. I also printed labels to put on my laminator so I would remember the important steps in the future.

[@BrendaEM]

When I was a kid, we used to make boards the hard way by cutting rubylith, and using photosensitive boards. Some single-use templates were made by putting water-proof glue over magazine articles, and then soaking them. Back then the only printers we had were dot-matrix, so the transfer method was still years off. You might be able to use a plastic clip such as those strips used to bind the edges of book-reports. Perhaps, something could be 3D printed. It seems that a lot of people were using cupric chloride because it can be regenerated, but I haven't tried it, personally. Good videos, as always. Thank you.
