We look forward to your inquiries so that all of our readers can learn
some valuable information.
1) Q. What is the advantage of the
four slot over round holes for lamination tooling?
A. The four slots allow any error due to
dimensional stability to be split from the center of the panel, the slots
also make it easier to lay up on the lamination pins without wrinkling
or tearing the inner layer.
2) Q. What are the benefits of soft
tooling plugs in drilling?
A. The soft tooling plugs eliminate any build
up of error from the tooling plate to the drill spindle. It actually zeros
the spindle to the tooling.
3) Q. Why use a Post Etch Punch?
A. Post etch punching of inner layers has many advantages as compared
to pre-etch registration methods. The tooling pattern is punched in the
inner layer after etching. All material movement resulting from artwork
instability, etching, black oxidizing, etc. is compensated for. Tooling
holes and/or slots that are punched before etching are subject to movement
during the etching process. This results in buckling or stretching of
the inner layers when pinning on the lamination plates which can cause
misregistration. Post etch punching eliminates this problem insuring an
accurate match between the inner layer tooling holes and lamination plates.
Since the layer to layer registration is achieved after etching, inner
layer artworks only need to be aligned front to back during exposure.
This can be accomplished with simple book printing methods. Book printing
eliminates the need for pinning of the artwork to the laminate. Artworks
are registered front to back and the panel is simply placed between the
artworks during exposure.
4) Q Why do I need to X-Ray drill
my drill tooling holes if I laminate on the four slots?
A. The advantage of Post-Processing laminated
panels are obvious. Panels lost during final drilling are extremely costly.
Post-Processing panels after lamination eliminates the requirement for
drilling test coupons or secondary X-Ray measurements to calculate drill
offsets. These calculations are usually based on a small sampoling of
panels, with the assumption that all panels are the same. This is not
the case however in production panels.
Variation from panel to panel can occur during lamination. Post- Processing
these panels in preparation for drilling requires X-Raying and drilling
new tooling holes in every panel based on the panels individual registration
characteristic. The result of this Post-Lamination is faster setups, no
program offsets, and increased thruputs on the drilling machines. The
downtime on the drill due to waiting for offset information is completely
eliminated.
