CEM-1 CEM-3 FR4 Single Sided Customized PCB

    The CEM-3 market application UL believes that CEM-3 and fr-4 can be interchanged, so fr-4 dual-panel is usually used as the replacement object.Since CEM-3 is similar to fr-4 performance, it is also possible to substitute on multilayer boards.Because the printed circuit board price competition is very fierce, so the four floor board market has also started to consider the choice of CEM-3.However, for the sheet (<0.8mm), the price advantage does not exist.CEM-3 printed circuit boards are now used in fax machines, photocopiers, instruments, telephones, automotive electronics, household appliances and other products.The earliest domestic development, development and production of CEM-3 manufacturer is shenzhen Pacific insulation materials co. LTD.The CEM-3 produced by the company is generally 10~15% cheaper than FR-4, and the product quality meets international NEMA and IPC standards.In recent years, some other copper foil factories in China have also started to develop or batch production of the new composite substrate.
