greets,
I've bought a Photoresist Roll+Developer+Resist Remover kit on eBay.
http://www.ebay.com/itm/262575896863
The two zip baggies don't have anything written on them, so I don't know which one is the developer and which one is the resist remover. The seller from China does not seem to understand English so I was not able to get an answer from her/him. Perhaps someone can tell me which one is which from the attached photo?
Thanks!
If it's just negative dry film photoresist, the 'developer' is probably sodium carbonate (washing soda), and the stripper sodium hydroxide (lye, caustic soda, draino). I wouldn't use what they provided if you don't know which is which, you don't want an unknown solution that might be sodium hydroxide, nasty stuff.
You can use sodium carbonate or percarbonate/peroxyhydrate to both develop and strip. 30g/L room temp is about right, not too critical, develop about 3-5 mins, strip about 15mins, warming a bit for stripping helps. Have a look in your laundry, you might have some already, usually those "oxygen whitening action" powders (i use Sard Wonder Oxy Plus) are just percarbonate and a surfactant, works great. Acetone will also strip, 30 seconds in an acetone bath and the resist will all shrivel and float off.
