Update: To get the best results, spray water on the copper clad PCB before applying the dryfilm sticker. This eliminates the bubbles easily. Push the bubbles away as if you were installing a phone screen protector. You may proceed with the clothes iron or laminating machine afterwards. Thanks for your tips in the comments!
What if I need to make the pcb double sided would I do the same thing on the other side
How do i do it with iron instead of laminating machine, my film dissolves too quickly in the lye
I love how you made your own UV exposure box and agitator
