What People Say’s About Us

"I am Mr.Matthew Roth from UK. Today I would like to share my shopping experience with you about E7circuits,At first, I just gave it try,but it is amazing. It takes me three days to receive the boards,very fast! Only two minutes order online, 1day production,2days air shipping. Price is very economical,It saved me a lot!!!The PCBs are best, Jeff is really helped with me, Thanks for E7circuits very much!!!, You can try them If you would like! Happy China Lunar New Year to All E7 guys!"

Mr. Mathew

“Ioften order components from E7 since they can offer me a best price!!!That is why I have been ordering components at their house since 2012. The parts are original and best!”

Mr. Grisha

Electronic Designer

“Everything worked perfectly. Very proffessional work.Very good quality and confiability.”

Mr.Gaston

Founder in a factory

Guess I'm the only one (yet) using e7circuitsJust took delivery of the biggest PCB's I ever have designedMy job for the last 32+ years have always been to design stuff that are getting smaller and smaller, it was very nice to do a design where you have to search on the PCB to find a specific componentI can say that the quality of the PCB from e7circuits is absolutely perfect! I have done lots of designs thru the years, used many different factories, but I would not hesitate to use these guys again (and no, I'm not sponsored or anything like that, just a happy customer !!)A couple of pictures of the gigantic board....
