Keywords Multilayers, Printed circuit boards, Sumitomo Bakelite
The new APL-D process for producing sequential build-up multilayers, which can be processed in standard technology as well as in micro via technology, creates considerable potential for rationalisation in the PCB manufacturer's production process.
System components, which have been specially developed and adapted to the process sequence, make it possible to produce multilayer circuits continuously. It is also possible to use a UV-curing resin system (APL-5004), which is applied using screen-printing techniques and a resin coated copper foil (APL-1103) which is applied to both sides, using the roller laminating process.
The process can be used to produce:
- •
Micro via multilayers (laser/plasma).
- •
Controlled-impedance multilayers.
- •
Very thin multilayers.
- •
Standard multilayers.
Advantages of the process
- •
Permits laser drilling, plasma drilling and mechanical drilling.
- •
Uniform thin dielectric spacing.
- •
Clean and undamaged copper surfaces.
- •
The glass fibre structure is not transferred to the copper surface.
- •
Solvent-free resin system.
- •
No tension in the material (stress-free and dimensionally stable).
ScopeProducts
- •
APL-1103 resin-coated copper foil.
- •
APL-5004 UV-curing resin system.
