Our Testing Experience
First Impressions
When I first got the MG Chemicals 415-4L Ferric Chloride Copper Etchant Solution, I was curious about how well it would work compared to other etchants I had used before. The bottle itself was a good size, easy to handle with its 4-liter capacity, and the dark brown liquid inside looked quite concentrated. I set up a small test with a copper board to see how quickly and cleanly it would etch. Right away, I noticed it was faster and more aggressive than the persulphate etchant I usually use, which was impressive. It felt like this product would save me a lot of time on my projects.
Daily Use
Using the solution daily for a few small PCB etching jobs was straightforward. The etchant worked consistently each time, and I liked that I didn’t have to keep mixing new batches. Because it’s more aggressive, it etched away the copper faster, which meant I could move on to the next steps quicker. I also appreciated how easy it was to store the bottle without worrying about the solution losing strength. I simply covered it tightly and put it aside for the next day.
Key Features in Action
One of the best things about this etchant is how aggressive it is. It really cuts down the etching time, which is great when you have multiple boards to work on. Another feature I found very useful was that the solution can be reused multiple times. After each use, I filtered the liquid and stored it back in the same bottle, and it still worked well for several sessions. This made it feel like a more cost-effective option compared to other single-use etchants.
Long-Term Performance
After a few weeks of regular use, the MG Chemicals ferric chloride solution maintained its strength and effectiveness. I didn’t notice any drop in performance or the need to replace it often. The bottle’s size also helped because I had enough solution to handle bigger projects without constantly needing to reorder. Overall, it proved to be a reliable and efficient product that I would happily recommend to anyone looking for a strong copper etchant that lasts.
