Abstract
The invention discloses an SMT printing template. The SMT printing template comprises an anti-scraping layer. The anti-scraping layer is made of rolled steel and is arranged on the surface of the SMT printing template. A composite material layer is arranged below the anti-scraping layer. The composite material layer is made of high polymer materials and photosensitive materials in a mixing mode and has certain viscidity. Reinforcing ribs are arranged in the composite material layer. The reinforcing ribs are made of alloy steel. A carrier plate is arranged below the composite material layer and is made of rolled steel. A template hole is formed in the SMT printing template. The cross section of the template hole has a certain gradient. The hole diameter becomes larger and larger from the periphery to the center. The SMT printing template is reasonable in design, and easy and convenient to manufacture, template cracking is well prevented, and working stability is improved.
Description
Technical field
The present invention relates to print field, particularly a kind of SMT printing stencil.
Background technology
Hyundai electronics industry develop rapidly, electronic product towards less, gentlier, thinner future development, more and more application of thin space, mould printing technique is more and more in electronics manufacturing application.In producing, electronic product electronic component kit PCB to be welded, first need tin silk to soften on PCB, and on PCB, have a lot of pads need to go up tin, the corresponding electronic component in position of each pad, adopt mould printing technology exactly the best approach of disposable pad that need to go up tin accurately upper tin.
The most simplicity of design of existing printing stencil, single with material, usually there will be the defects such as template cracking, print solder paste off normal, affect product quality.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of SMT printing stencil, and pattern hole cross section becomes certain gradient, and Yue Wang center, aperture is wider, has avoided the problems such as generation tin sweat(ing), to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of SMT printing stencil, comprise anti-scratch layer, composite layer, support plate, reinforcement, pattern hole, described SMT printing stencil comprises that anti-scratch layer is made up of steel, be located at SMT printing stencil top layer, anti-scratch layer below is composite layer, composite layer is mixed by macromolecular material and photosensitive material, there is certain viscosity, in composite layer, be provided with reinforcement, reinforcement is made up of steel alloy, composite layer below is support plate, support plate is made up of steel, SMT printing stencil has pattern hole, pattern hole cross section becomes certain gradient, and Yue Wang center, aperture is wider, anti-scratch layer, composite layer, support plate, between layers by adhesive bond.
Preferably, described pattern hole upper surface and lower surface are all provided with rounding, and in pattern hole, center is provided with protruding convex arc.
Preferably, described reinforcement is manufactured by steel alloy, and reinforcement is that cross section is circular steel wire, is evenly applied in composite layer inside.
Adopt the beneficial effect of above technical scheme to be: this SMT printing stencil adopts multiple material Integrated using, anti-scratch layer is made up of steel, composite layer is mixed by macromolecular material and photosensitive material, reinforcement is made up of steel alloy, support plate is made up of steel, the combination of multiple material, improve the mechanical property of SMT printing stencil, anti-scratch layer is made up of high-carbon steel, hardness is large, and anti-wear performance is good, has prevented well the defects such as template cracking, the use of reinforcement, has improved the tensile strength of composite layer.SMT printing stencil has pattern hole, pattern hole cross section becomes certain gradient, and Yue Wang center, aperture is wider, in pattern hole, center is provided with protruding convex arc, use the pattern hole of this kind of structure to prevent the print solder paste off normal that plain bore easily occurs and easily produced the problems such as tin sweat(ing), simple in structure, easy to manufacture, serviceability and the life-span of having improved printing stencil.
