less dangerous photoresist striper chemical

manojroy123

We have to use caustic soda as a stripper for striping photoresist. It is a very dangerous chemical and it eats away our hand and skin. Can anyone suggest better photoresist stripper chemical which is less expensive and less dangerous.

    I've never used it. I gave up making my own PCBs a very long time ago.

    Can't you find somewhere local to make (or import) your boards - if your process is at the stage where your hands are getting into the chemicals you will get much better results if you buy in.

    "We have to use caustic soda as a stripper for striping photoresist. It is a very dangerous chemical and it eats away our hand and skin. Can anyone suggest better photoresist stripper chemical which is less expensive and less dangerous."

    It's an industrial process, the chemicals won't be completely friendly. If you're DIY'ing for a prototype then you're not using a lot anyway. Isn't caustic soda about the cheapest chemical ever? I can't imagine significantly cheaper chemicals. It might be sold under other names (check your household DIY stores, it's a consumer item).

    If it's eating hands and skin perhaps you're using too much. Just a teaspoon of granules is usually enough. If you're not using gloves then wash any accidental splashes immediately. Wear eyewear too.

    What is the concentration of the solution? Do you prepare it or it is commercial?

    If preparing it, be careful with the heat generated. Also, shelf life is short.

    Talking about concentration is important. Usually acid chemicals are considered dangerous but basic ones not, and a really basic chemical can cause severe damage. If concentration is low you should be ok with appropiate gloves, glasses.
