| B0101 | Has anyone used dry film photoresist? | 05:47 |
|---|---|---|
| azonenberg | Yes, but not at these feature scales | 05:55 |
| azonenberg | only on PCBs | 05:55 |
| azonenberg | i did hit 5um features with dry film on copper PCB experimentally using projection lithography | 05:55 |
| azonenberg | but was unable to etch the 35um copper layer obviously :P | 05:55 |
| B0101 | I found that dry film photoresist is much cheaper than liquid based photoresist | 06:04 |
| B0101 | Well, I'm not sure if I can be used for making working devices | 06:05 |
| azonenberg | It can be used but you have to know some of the quirks | 06:06 |
| azonenberg | for example it stays flat when you apply it | 06:06 |
| azonenberg | which means it won't have step coverage | 06:06 |
| azonenberg | this may be good or bad depending on the application | 06:07 |
| B0101 | ok, thanks for your info | 06:19 |
