Film Series for IMD and FIM Process
LonghuaPC-1801-OMF is a polished/polishedultra-thin FIM film, which is produced by ultralow stress techniques in cleanroom. It offers advances in thickness tolerance, tensile strength andformability, etc., which make it the ideal choice for FIM applications likeslim battery cover of mobile phones, and top cover of mouse, etc.
