I have a hobby/business making guitar effects pedals both new circuits and clones of vintage circuits. I started out using the toner transfer method to etch my boards and I thought I was getting pretty good results. Oh how wrong I was. I switched to the photo resist method and will never look back. My circuit boards are sharp and clean and above all, quiet. This 500ml bottle of MG Pos Dev is much cheaper than what I had been buying and does a great job of removing the resist on the boards I'm using. (GC Tech Printed Circuit Board) I keep what I need in a pyrex dish with a lid and store it in a dark room for long life.

Not much to say here except that it works as expected. The solution is concentrated so it makes a sizable amount. I used a 8x8 Corning baking tray to hold my project and gently swirled it for a few minutes. The pattern developed quite nicely and I was surprised at how delicate of lines I could use on my project. I'm thrilled with the results.

My daughter and I used several of the MG Chemical products to make a custom PCB.
The PCB products worked perfectly the first board we made.
I would buy MG Chemical products again.

This is the developer used with the 600 series presensitized boards. I have no complaints about it. This formula is very strong, it will develop a board in less than 20 seconds, using the 1:10 mix. Great product!

Like one of the other reviewers I used to use the toner transfer method. But I was very frustrated with how inconsistant the results were. I just etched my first board with this and one of MG Chemicals presensitized boards. I was stunned by how well the board came out. Very sharp traces and no pitting. For the UV light source I used a cheap fluorescent fixture form the home improvement store.
I highly reccomend this product!

I don't know why they call it developer. It the same stuff as the drain cleaner (sodium hydroxide) a few pennies worth.

Hey this stuff works great it takes the stuff right off the circuit boards leaving a perfect circuit on the board for the copper to be eaten away!!!!!!!

Ordered by mistake. All chemicals I've gotten from MG have been good so no reason to think this is not the same. Will pick up sensitized boards at Frys and try the developer out.
