    摘要: A chip-on-flex HDI module is fabricated by dispensing encapsulant material onto the components of a populated dielectric film or sheet in an interrupted pattern which leaves the backsides of selected components free of encapsulant. The dispensing is accomplished by relative motion of the dispenser tip and the populated film, with the dispenser tip at a height slightly above the desired liquid fill height during dispensing. At the locations of the components which are to be free of encapsulant, the dispensing stops, and the tip may be raised to prevent residual viscous matter on the dispenser tip from contacting the backside of the exposed component.
