Semi-Flex PCB

Semi flex PCB is a flex-rigid PCB, typically 4 layers, made entirely of FR4. Unlike conventional flex-rigid PCBs, the flexing element is not polyimide but a thin FR4 core with two layers of copper specially treated to flex without cracking. A less robust solution uses a depth-milled layer rather than a core.

While this type of flexible circuit may be more expensive to design and produce, it does offer a number of important advantages. For instance, the reduced size makes it easier to fit more components into a smaller space. This can actually help to lower overall system costs. Additionally, because they require the need for fewer interconnects and related parts and components, these semi flexible pcb can also prove to be more reliable and require less maintenance in the long run.

As with all types of flexible circuit boards, the semi-flex PCB will perform well in even the harshest environments, especially those featuring extreme heat. A semi-flex  board is also easy to test, making it well-suited for prototyping.

    Wonderful blog! The noble act of removing PCBs from the Hudson river will motivate PCB manufacturers in Canada to adopt eco-friendly materials. This will promote the message of maintaining a clean and green Earth.

IoT and Smart City: éolane and the Chinese town of Dongguan Sign a Strategic Partnership

Recently, the Dongguan Chinese delegation signed a cooperative agreement with éolane, paving the way for a partnership between the municipality and the group to work together on a smart city project. The agreement was signed at the éolane headquarters in the Maine & Loire, in a friendly atmosphere, followed by a site visit and a photo session. The day continued with a visit to the IoT City in Angers, of which there has been a replica in Suzhou, near éolane China subsidiary, since April 2016. Emilie Blanchon, business manager for éolane Supply Chain Management in China , participated in the success of the organisation of the meeting. She ensured the smooth unfolding of the event, especially in terms of protocol. A path for the development of joint projects Boosting cooperation between Chinese companies and éolane in Europe, this partnership is very promising for the development of new practices for emerging or well-established companies. It is a great opportunity to demonstrate...
