puedeng gumamit ka ng transparency... or the other method is baby oil...print mo circuit sa magandang printer... tapos apply mo ng baby oil, hangnag magign translucent ang paper..punasan mo excess oil... ready na ipatong sa photopcb. this is applicaple sa medyo makakapal na traces up to 25 mil (based on my experience)
I have done this but using laser printer.I used GLOSSY paper from magazines. You could use your new FHM issue. Needs the PCB to be cleaned and sanded well so that toner will stick.Print the positive mirror image of the design.Place the paper on the sanded/cleaned PCB with the toner marking touching the copper of the PCB.I placed another clean bond paper (without printings) on top as protective layer.Iron the paper. Slide the iron without moving the magazine paper.If you feel it already sticking. Just estimate it or do trial and error for the exact time because this depends on your clothes iron.Then dip it in cold soapy water. Wait for a few minutes until the paper is partially dissolved.Rub the paper off with your thumbs but carefully not to include the toners stuck on the copper.The difficult part to the remove is the holes on the pad. So bigger pad holes is better.After, you could directly dip this to your Ferric chloride of Cupric chloride solution.
Pde po bang instead na laser printer ay XEROX?may nabasa kac ako sa net
Madali lang ito. Ang PCB design i-print mo using inkjet or laser. Tapos ipa-clear photocopy mo, several copies. Tell the attendant to set to "very dark" setting para oki ang result. Pwede mo gamitin yung special na bondpaper. Tapos plantsa-method na
i use backing sheet of wallpaper stickers, mas kumakapit talaga sa PCB pag-iron mo within 20 seconds of full settings ng electric iron mo.mas maganda ang transfer kung kaka-labas lang ng printout sa laser printer/xerox machines at iplantsa mo na.
Hoy Lito!! bat mo naman siniwalat yung process natin?? bwehehehe...nice to see you here boz...I totally agree...used the sticker backing paper..yung madulas na paper na naiiwan after removing the sticker..print with laser printer or any copier machine (toner type ha) then iron it on habang mainit-init pa!!RBT
sabi ko na ikaw yan rhonnz!akala ko kasi hindi mo sikreto yan, kasi sinabi mo sa akin HEHEHEHEHE!!!okey laang yan, at least naibulgar natin na sayo nagmula yang process or teknik na yan:CORRECT or BEST MEDIUM for Iron-On transfer sa PCB etching!
