DuPont has sold over 100 automatic laminators (ASLs) over the
last decade. Sixty percent of these were originally equipped
with wet lamination capability.
Although, the number of PCB fabricators using wet lamination is
small, this is misleading because wet lamination:
* Should only be used in print and etch.
* In practice is only used in fine line acid print and etch.
* Is mainly used by large fabricators.
In reality, the amount of resist that is wet laminated for acid
print and etch is much higher than responses to TechNet would
indicate.
>From our view, wet lamination clearly improves conformation,
which reduces opens and nicks for print and etch. Most shops
would prefer not to use wet lamination because of the performance
and equipment related problems that can occur. However, the
bottom line is that for some fine line fabricators, yields are
higher with wet lamination.

Address,
Thanks for the responses on the Wet Lamination Questions. Here's
the second part: Most Automated Cut sheet laminators I've come
across are Dry Lamination versus Wet. Does anyone run a Cut Sheet
Laminator using the Wet Lamination process or are all Automated Cut
Sheet Laminators Dry Lamination? It would explain why the overwelming
responses did not use Wet, if the last statement is true. Please advise.
Thanks
John Gulley
