A list of PCB Manufacturers who can fabricate CEM-1 Printed circuit boards. PCB Directory is the largest directory of CEM-1 PCB suppliers and manufacturers on the internet. Use the filters provided to find companies based on their capabilities.
What are CEM-1 Printed Circuit Boards?
PCB boards which use two layers of woven glass fabric and paper (cellulose) along with epoxy as the substrate material are called CEM-1 PCB boards. This material is milky white or milky yellow in colour with a smooth finish and used for single layer PCB fabrication only since it’s not compatible with plated through hole (PTH) technology.
CEM-1 provides excellent electrical and mechanical properties and is compatible with the lead-free reflow technology since it has a higher transition temperature than FR-4. It also has a superior flexural strength i.e. the ability of the dielectric to handle physical stress without breaking. CEM-1 is non-toxic and halogen-free and doesn’t contain phosphorus and antimony. It also holds good dimension stability as well.
The main disadvantages of the CEM-1 substrate when compared to FR4 are its mechanical characteristics which result in very fragile boards.
PCB Directory has listed the leading CEM-1 PCB fabricators and manufacturers and made them searchable through their location and capabilities. You can select the country or state to narrow down on local CEM-1 PCB manufacturers or companies that can develop your printed circuit boards who are close to where you are located. In addition to this, you can also select the capabilities that you are looking for in a CEM-1 PCB supplier, like - Number of Layers, Type of Board, board thickness etc. - We narrow down the list to show you the companies who can cater to your requirement.
