VAATLAMINERINGSPROSESS OG -INNRETNING.

摘要

Apparatus for wet laminating a photopolymerizable film (12) onto circuit board panels (14) or other substrates. The apparatus is easily and quickly convertible from dry laminating to wet laminating with the rollers (22,23) therefor mounted in bearing blocks which are insertable in slots (92) in brackets (86) at each end and removable therefrom. The lower roller (23) thereof has a gear (118) the teeth (120) of which are meshable with the teeth (112) of an idler gear (114) for transmission of rotation power thereto. Elongate tubes for applying a fluid, which suitably comprises between 0.1 and 10 wt.% of a heterocyclic metal-chelating agent, to the wet insertion rollers for application thereof to the panels are contained in a yoke which is adjustable next to wet insertion rollers for wet laminating or away from dry insertion rollers for dry laminating.
