Wet Lamination Process And Apparatus

This paper covers the effects of this process on wrinkles in the dry film resist and on the dimensional stability of clad laminate.

Wet lamination process and apparatus.

The lower roller thereof has a gear the teeth of which are meshable with the. Another lamination process uses a lamination press after materials are combined in a thicker structure than film. The ceraso and miyake patents discuss the lamination process and apparatus in greater detail. Further discussed are the techniques for avoiding wrinkles and dimensional.

The glass is protected during all wet chemical processing. The improved resist adhesion to the gold metallization surface is attributed to a complexation or chemisorption mechanism. The process and apparatus for dry lamination is commonly known to those of ordinary skill in the art to which this invention pertains. As an example azdel a glass reinforced thermoplastic composite made with continuous glass mat is produced using an extrusion lamination operation film continuous random orientation glass mat and molten resin are combined in a lamination process using a sandvik double belted.

Previously lamination cavities have been milled into the electrical package to about half of the thickness in the areas of the optical windows. It s hard to find a paper film or foil product that isn t a laminate whether the layers are from adding coatings or combining two or more substrates. A process is disclosed for improving the adhesion of a polymeric resist to a gold metallization surface. Specific processes differ primarily by how the adhesive is applied and converted from a liquid to a solid.

The present specification describes improvements in such apparatus for wet laminating. Apparatus for wet laminating a photopolymerizable film onto circuit board panels or other substrates. There are several laminating processes that can be easily adapted to production. Wet laminating machine suitable for laminating all types of paper film and aluminum foil such as cigarette box wrapping lunch and cake boxes and etc.

The laminating process has become ubiquitous on converting machines. Wet and dry lamination the manufacture of film laminates is a relatively simple continuous process of coating and bonding. Tension problems during the drying process are eliminated by use of the micro location offset via dancing roller control systems which allow for foil 6 micron to laminate with other. 1 16 of 931 results for lamination scotch thermal laminating pouches 200 pack 8 9 x 11 4 inches letter size sheets clear 3 mil tp3854 200 4 9 out of 5 stars 5 100.

The process includes the use of a chelating silane as an adhesion promoter between the resist and the gold metallization surface. The dry film lamination process involves adhering a composite structure of photopolymer and polyester film to a metal clad dielectric laminate.
