By adopting this method the formation of form belongs to a deposition of metallic atomic level, so that it can form roughness-free opening.
Description
Technical field:
The present invention relates to the making method of a kind of surface mounting technology (SMT) template, this template is mainly used in the assembling of surface mount elements.
Background technology:
Along with hyundai electronics package trade technology develops towards the subminiaturization direction, the components and parts size is more and more littler, and packing density is more and more higher.And the quality quality of printing stencil is the key that influences soldering reliability and product first-pass yield.According to statistics, the reason that caused because of the printing soldering paste during all SMT lost efficacy has accounted for about 90%.As seen solve the quality of SMT template, development is fit to the SMT template of continuous miniaturized device, is one of gordian technique of SMT technology.
The manufacturing of SMT template can be divided into method manufacturings such as chemical corrosion, laser cutting substantially.Chemical corrosion method is because problems such as sideetching can not produce high precision, highdensity template, and laser cutting makes its otch roughness reach the scope of 3 μ m because it belongs to the principle of heating power cutting, also is not suitable for the template of ultra-fine pitches.
Summary of the invention:
Purpose of the present invention is exactly in order to overcome the above problems, a kind of making method of surface mounting technology template is provided, solve the opening Burr Problem that the conventional template manufacturing process exists, make carrot-free SMT template, improve ultra-fine pitches device soldering paste bite rate and homogeneity.
For achieving the above object, the present invention proposes a kind of making method of surface mounting technology template, it is characterized in that may further comprise the steps: 1) preparation electroforming solution; Exposing, developing through pad pasting on the stainless steel substrate of pre-treatment; 2) stainless steel substrate after will developing is put into electroforming solution electroforming nickel dam; 3) electroformed layer is peeled off from stainless steel substrate.
Aforesaid method can be called for short electrocasting, owing to adopted this method, the shaping of template is the deposition that belongs to the atoms metal level, thereby can form the opening of no roughness, the precision that its roughness only is subject to exposure basically, develops, and expose, developing technique becomes visual roughness almost can ignore.
The specific embodiment:
The present invention is described in further detail below by specific embodiment.
Say that briefly the present invention mainly may further comprise the steps: 1) preparation electroforming solution; At the front place of process Pad pasting exposure, development on the stainless steel substrate of reason; 2) stainless steel substrate after will developing is put into electroforming Electroforming nickel dam in the liquid; 3) electroformed layer is peeled off from stainless steel substrate.
