Abstract
Methods and apparatuses for attaching metal stencil foils to screen mesh using thermoplastic materials. Mechanical, rather than adhesive, attachment of metal stencil foils to screen mesh is accomplished by melting thermoplastic material so as to encapsulate portions of metal stencil foils and screen mesh resulting in faster, less expensive, and more durable bonding.
Claims13
A stencil assembly comprising a metal stencil foil having peripheral apertures attached to a screen mesh by means of a mechanical bond with a mechanical bonding material able to be melted by heating and to harden after removal of said heating.
A method of attaching a metal stencil foil, having peripheral apertures, to screen mesh using a mechanical bonding material, having greater length and width than the length and width of said metal stencil foil and having a large central open area, said method comprising the steps of;
- (a) placing said mechanical bonding material in a template and positioning said metal stencil foil such that each edge of said metal stencil foil lies within the length and width of said mechanical bonding material and said apertures of said metal stencil foil are outward of said large central opening of said mechanical bonding material,
- (b) placing said screen mesh over said metal stencil foil and said mechanical bonding material,
- (c) applying sufficient heat and pressure to soften or melt said mechanical bonding material and force said mechanical bonding material into said apertures of said metal stencil foil and into openings of said screen mesh above said apertures and above said mechanical bonding material to the outside of said metal stencil foil,
- (d) removing said heat and pressure so as to cool and harden said mechanical bonding material.
A method of attaching a metal stencil foil, having peripheral apertures, to screen mesh using a mechanical bonding material, having a length and width less than or equal to the length and width of said metal stencil foil and having a large central open area, said method comprising the steps of;
- (a) placing said mechanical bonding material in a template and positioning said metal stencil foil over said mechanical bonding material such that said peripheral apertures of said metal stencil foil lie outside of said large central open area of said mechanical bonding material,
- (b) placing said screen mesh over said metal stencil foil and said mechanical bonding material,
- (c) applying sufficient heat and pressure to soften or melt said mechanical bonding material and force said mechanical bonding material into said apertures of said metal stencil foil and into openings in said screen mesh above said apertures of said metal stencil foil,
- (d) removing said heat and pressure so as to cool and harden said mechanical bonding material.
