haha this is such a Finnish presentation with barely enough information. I've got great friends from Finland and they're great at what they do and funny and genuine people BUT they're not the one's who wears your ears out, I'll tell you! :D But as an overview it was a great video! I know what I need to search for and I think I will like the process with chemicals and stuff.
I know im asking randomly but does anybody know a tool to log back into an Instagram account?? I was stupid lost my login password. I would appreciate any tricks you can offer me!
@Chad Elliot Thanks for your reply. I got to the site thru google and im trying it out atm. Takes quite some time so I will reply here later with my results.
Je n'ai jamais obtenu que des résultats moyens avec cette méthode de film. Je suis revenu avec mon Bungard. Un peu plus cher, mais gain de temps et précision.
Never mind I found this page: www.chegg.com/homework-help/definitions/percent-solution-6 Which has this example: Example: A 7% (w/v) NaCl solution means that a mass of 7 g of NaCl is dissolved in a solution containing volume 100 mL. (b) Percentage by volume, v/v
No, normal indoor lights will expose the film very slowly. I usually work in a room with warm-white LEDs and I haven't had a problem this far. I don't think it is necessary but I cover the PCB with an upside-down plate or some aluminum foil (just placing it on top, no wrapping or fancy stuff) if i have to leave the PCB for a few minutes.
A bit of an old question but yes. A warmer solution will work faster. But if it is to warm it will start affecting parts that it shouldn't, make sure that it doesn't get to hot, I'd it below 60c mostly for your own safety
Help please, I am running into an issue where sections on the board just refuse to etch, the etchant removes most of the parts but there are some areas that refuse to come off
@@Berghiker while a dedicated PCB mill is indeed simpler for small batches this process is what is used for every single large scale PCB manufacturer where .3mm precision is pretty much the base-line precision. But yes, it takes some time to learn and a bad if your printer can't get the transparency dark enough it is allmost impossible to get a good result.
@@Berghiker that's probably the better option for rapid prototyping. if you need lots of pcbs then just better to use a company to make and ship them to you
I'm no nature hippie... but one definitely should NOT be rinsing any amount of ferric chloride down the drain. Not only is it somewhat toxic, it's byproducts (copper compounds) are even more toxic and it puts load on sewer and septic systems. If that wasn't already bad enough, it's highly corrosive to your pipes... which are often made of iron or copper... One should first react it with one of the two other chemicals you have, then evaporate all the water. The solids you have remaining can safely discarded with the rest of your municipal solid waste. Bottom line, it's so easy to deal with the right way that there is no excuse for being too lazy to do it right.
"Don't you want to wait for the pcb delivery for weeks? With these instructions, you make the pcb yourself in an hour." yeah but then we still have to wait for the necessary materials to arrive. i dont have ferric chloride, or dry film in my dollar store.

Holly crap this is beautiful!
Great video! Thank you.
you just changed the way I do etching. thx
Very informative, precise and simple video. Hope more videos from you.
Nice video!
Thank you
how do you size the print for this to fit components
very cool

@Chad Elliot It worked and I now got access to my account again. Im so happy!
Thank you so much, you really help me out :D
please give wattage of lights
Can I handle dry film photoresist witj 7 watt light? or do I need red light to handle it? :)
yellow is probably fine like a low pressure sodium lamp

How many grams of each substance per liter of water? Please answer.
Never mind I found this page:
www.chegg.com/homework-help/definitions/percent-solution-6
Which has this example:
Example: A 7% (w/v) NaCl solution means that a mass of 7 g of NaCl is dissolved in a solution containing volume 100 mL.
(b) Percentage by volume, v/v
good video information is appreciated. the film is positive or negative?
Negatif.
How to make the Sodium Carbonate solution: Mix 1 gram NaCO3 with 100ml water.
can acetone be used instead of sodium hydroxide?
Yes
Do you need a darkroom for the film when working?
No, normal indoor lights will expose the film very slowly. I usually work in a room with warm-white LEDs and I haven't had a problem this far. I don't think it is necessary but I cover the PCB with an upside-down plate or some aluminum foil (just placing it on top, no wrapping or fancy stuff) if i have to leave the PCB for a few minutes.

thank you, excellent video tutorial!!! thumbs up and a sub from me. mike
Does the temperature of the developer solution matter?
A bit of an old question but yes. A warmer solution will work faster. But if it is to warm it will start affecting parts that it shouldn't, make sure that it doesn't get to hot, I'd it below 60c mostly for your own safety

do you use vellum as a replacement for transparent film?
Can i use a inkjet printer and trasparent sheet (for inkjet) to make the master?
Yes you can
Why you cut two piece of film?
One piece is not dark enough.
mine got gelo,..
What does it mean by 1.5% , 25% and 5% plz answer
Strenght of the solution.
I agree too! What the hell does 1.5% mean? Rather give how many grams of this with how many ml of water! Much better!! Anyone can understand that.
@Printax Chennai Ok.
someone commented that 7% means 7 grams of substance per 100 mL water. Agreed that percentage is annoyingly ambiguous.
How many minutes to develop the PCB? Is 10 mintues enough?
@David Wanklyn I'm done with this unreliable and inconsistent process. I'm buying a small CNC machine!

Sorry, I can't hear what you say...
Too complicated
I'm no nature hippie... but one definitely should NOT be rinsing any amount of ferric chloride down the drain. Not only is it somewhat toxic, it's byproducts (copper compounds) are even more toxic and it puts load on sewer and septic systems. If that wasn't already bad enough, it's highly corrosive to your pipes... which are often made of iron or copper...

sodium persulfate is so much better for etching. it lasts 10x longer and is non-corrosive. just don't get it on your clothes!
"Don't you want to wait for the pcb delivery for weeks?
With these instructions, you make the pcb yourself in an hour."
yeah but then we still have to wait for the necessary materials to arrive. i dont have ferric chloride, or dry film in my dollar store.
Very low grade work
