NEUROCAM® STATISTICS

Data enfolded in database, any time that the system detects misregistration during the test-coupons drilling, are available to be explored selecting:

1) PANEL SIZE
2) LAMINATE THIKNESS
3) TYPE (GROUND/SIGNAL/MIXED)
4) SUPPLIER
5) RANGE OF HISTORY TIME

DATA EXPLORERS 

Statistical data can help the choice of materials and suppliers, enabling more homogeneous lay-ups building.
Really, I found that it's not sufficient to have statistical data in production environments where a lot of new lay-ups are produced everytime.
In any case I confirm the usefulness of them in order to perform a first rough correction on the films, specially when working on a known lay-up.
The goal of this project is to give a solution that behaves in "REAL-TIME" and in "LONG-TIMES", with a very little price compared with x-ray machines. 

ABOUT CONSISTENCY OF DATA INSIDE A LOT

This system is intended more useful in environments where there is consistency of data on innerlayers misregistration inside a lot. Some people working in pcb fabrication tell me that this condition is not present in their process. Really I think that a random error of registration inside a lot can exist, but it must be a fraction of the error caused by material shrinkage. Infact a random error can be generated by flaw in some mechanical registration systems or in wrong procedures, and nobody can accept 0.0005In/In for this cause. I think that a mechanical registration error (random) can be reduced to be:

"mr_err < 20% shr_err"
where
mr_err = mechanical random error and
shr_err = medium material shrinkage error.
There are not "problem solver" systems if some actions are not performed and some rules are not considered during process:

1)Inside a lot all the laminates of the same type must be supplied by the same firm and must have the same characteristics(resin content is the most important).

2)The artworks must be stabilized before use(indipendently from the fact that one can make here a first compensation of laminates shrinkage).

3)Any mechanical registration system involved in the process must be adequate to the required precision.
