Circuit Board Technology for Critical Manufacturing Points
We have increased our production capable layer count
exponentially since 2002. With multi-layer
PCB technology there are many critical manufacturing points
that need to be addressed.
Multilayer Registration Control
Prediction: Layer-to-Layer Alignment
One primary characteristic is layer to layer alignment. In addition to our MultiLine
tooling systems, we have purchased and implemented the use of the
system to fine tune our process and achieve highly accurate scale factor predictions for a variety of material types
and core thicknesses.
Saturn has purchased and installed four Olec AT-30 automatic alignment exposure
units. These units use four cameras to align artwork top to bottom, and then use panel motion systems to automatically
adjust the panel position to a best fit to the artwork. Furthermore, these units have hybrid-collimated light units that
ensure exposure light attacks the panel at 90 degree angles to the artwork, which is critical for fine line resolutions.
Microvia Formation Capabilities
We have installed advanced PCB drilling systems (Excellon Century
2001 and Mania Micronics 86) capable of up to 180k RPM spindle speed, which is critical for microvia formation.
Furthermore, our advanced systems use linear motion technology for X, Y, and Z axis motion. This results in not only a
higher throughput, but also increased registration accuracy.
Standard Production and Blind Microvias
Saturn has built a custom automatic PCB plating line that has been
designed and constructed primarily in-house. The intent was to minimize plating variation, which is the main goal of
production plating. To address issues with plating small and blind holes we use mechanical agitation to allow
chemical to flow through holes and vibration to remove air from
microvias and blind microvias.
2 Mil Line & Spacing
Saturn has installed a new Hollmuller SES line. This line incorporates the latest in
spray technology that minimizes chemical puddling. This is line capable to accurately and uniformly etch down to 2 mil
lines and spaces.
