VACUUM EVAPORATION APPARATUS
20180207677 · 2018-07-26 ·

The invention provides a vacuum evaporation apparatus, wherein the magnetic plate comprises a plurality of magnetic units respectively corresponding to different areas of metal mask to attract the corresponding areas of metal mask to low surface of substrate by magnetic force, the driving mechanism comprises a plurality of driving units correspondingly one-to-one to magnetic units, and the magnetic units are driven by corresponding driving units to move upward/downward independently so that the stress generated during the mask sheet of metal mask attached to substrate is fully released by adjusting the movement order of magnetic units to reduce difficulty on metal mask design and improve yield rate. Moreover, the corresponding magnetic units are adjusted in real-time according to the color mixing situation of products to improve the equipment utilization rate, and the magnetic force on corresponding area of metal mask is independently adjusted according to product color mixing situation.

Stencil set and system for printing solder paste for printed circuit boards

A method of printing solder paste in a component board and a stencil set for doing the same are disclosed. In one embodiment, the method includes using a first stencil having a first thickness to print solder paste into at least one through hole in the component board. The method further includes using a second stencil having a second thickness to print solder paste for at least one surface mounted part on the component board, subsequent to using the first stencil.

MASK FRAME ASSEMBLY AND EVAPORATION APPARATUS
20180196343 · 2018-07-12 ·

A mask frame assembly and an evaporation apparatus are disclosed. The mask frame assembly comprises a frame and a mask plate fixed on the frame. The mask frame assembly is provided with alignment marks, which comprise a first alignment hole arranged in the frame and a second alignment hole arranged in the mask plate. The first alignment hole is a through hole; or the first alignment hole is a blind hole, the deepest position at a bottom of the blind hole does not overlap with an orthographic projection of the second alignment hole on the frame. The mask frame assembly effectively solves a problem in which liquid residuals in alignment holes of the frame interfere with alignment.

DIVISION MASK
20180065143 · 2018-03-08 ·

A division mask includes a main body including at least one opening pattern, and a clamping portion at an edge of the main body, the clamping portion having an increasing width with respect to an increasing distance from the main body, and the clamping portion including a fan-out portion extending from the main body and including at least one dummy pattern, and at least one branch portion having a decreasing width with respect to an increasing distance from the fan-out portion.

DEVICE, METHOD, AND KIT FOR APPLYING STENCIL PATTERNS TO A FABRIC AND FABRIC-LIKE MATERIAL

The present invention relates to devices, methods, and kits for applying stencil patterns to surfaces, particularly to surfaces made of fabric or fabric-like materials.

One-piece foam frame for mounting screen and/or screen stencil film to create screens for manual and small off-contact printing substrates
09573357 · 2017-02-21 ·

A portable one-piece foam frame for use in securing a screen and/or screen stencil film for use in an off-contact stenciling operation. The assembly includes a paper or release covering an adhesive on one side of the frame. A non-skid coating may be applied to the base of the frame to keep it from shifting or moving during a stenciling operation.
