Introduction: DIY Flexible PCB

Picture of DIY Flexible PCB

Some Months ago, I tested idea about flexible PCB. and results were good.

I just uploaded some pics on instructables but rejected cause there are not enough documentation.

i'm Korean so editing documentation in English is some hard. and So busy long times.

now i re-publish this.



there are very Thin copper plate in train model shop(or other model shop,.. anyway)

about 0.001~0.003" are good. I used 0.001 and 0.002.


Step 1: Toner Transfer

do the same way just Toner Tranfer Method. do on copper sheet.

but you must STICK KAPTON TAPE BEFORE ETCHING.

after etched, you can solder like normal PCB


The most important part, is to adhere tightly the copper plate and tape here.

If you miss small gap between tape and copper sheet,

there will be etching acid and copper sheet cannot protected.

Step 2: Result

this test was some months ago, it was cold so etching time takes long.

while do something i forgot this so it takes about 3 hours.,

the pattern is almost gone but not 100%.

so i wired LEDs and power. and it's glowing!

Hi .. I have a question. The pic 1 shows Brass shim but what about using Copper shim instead ??

I cannot find that thin(0.001") copper shim. if you can that'll be good.

After the iron,under the copper it's all black, is it possible that my
iron is too hot, the iron settings is before steam. What do you suggest?
thank you!|

i always use highiest temp. and high pressure(press copper with your body, not just hand)
