Multilayer PCB Fabrication
Multilayer PCB Fabrication
E3PCB has grown dramatically over the last decade, from a small PCB manufacturer with a select group of clients back in 2005 to a full feature PCB manufacturing operation that is one of the most preferred PCB solution providers in China today, with clients from all over the globe in a wide range of industries.
We are continually upgrading our full feature PCB service with better equipment, more training and more efficient techniques to provide the highest quality, full feature PCB manufacturing and assembly for our clients. We hold ourselves to the highest standards of quality and efficiency, and our clients know it, coming to us from industries like military, aerospace, medical, telecommunications and education, to name a few.
We continue to expand and challenge ourselves to make sure we can help make your printed circuit board-using company as successful as it can be.
The E3PCB Advantage
What makes E3PCB the preferred choice for full feature printed circuit board manufacturing? For one thing, it’s the variety of our offerings and the flexibility of our solutions. We can make just about any printed circuit board you can think of, from Flex PCBs to heavy copper PCBs to ceramic PCBs and more. Shape and size considerations are of no concern for us, nor is the size of your order.
We can supply you with RoHS-compliant boards, high-frequency features or high-temperature features – simply let us know what you need, and we’ll put our expert designers and fabricators to work creating boards just for you.
That’s the best part of the E3PCB advantage – we have experts in every phase of PCB development. We are a start-to-finish, turnkey, full feature PCB manufacturing solution that can help you with the design, fabrication and assembly of your board, all the way through testing to packaging and shipping. When you’re working with E3PCB for your printed circuit board manufacturing, you won’t be talking to three different companies to get everything done.
