PCB flexibles (flex)

La demanda de PCB flexibles está aumentando en todos los sectores, especialmente en los mercados médico, militar e industrial. Los volúmenes para estos mercados son relativamente bajos, por lo que NCAB trabaja con una serie de fábricas asiáticas especializadas en pequeños volúmenes para una gran variedad de productos (HMLV, por sus siglas en inglés), que responden perfectamente a estos criterios tecnológicos y de volumen.
