Abstract
The invention discloses a preparation method of a superfine noble metal extrusion flat die and relates to the technical field of die production. The die is prepared in a metal workshop by taking natural diamond as a core and pure stainless steel as a housing. The method has the benefits that the method is concise in process flow and reasonable in raw material ratio, the pure stainless steel is taken as the housing and the natural diamond is taken as the core; internal refinement of the die is ensured; and the die can prepare a refined lead wire easily, is a metal extrusion flat die irreplaceable by other dies, can be widely used for manufacturing various flat ribands made of noble metals such as gold, silver, a platinum-rhodium wire, an aluminum-silicon alloy and single crystal copper, and is convenient to popularize and use.
Description
Technical field
The present invention relates to mould production technical field, be specifically related to the flat molded Preparation Method of a kind of super thin noble metal extruding.
Background technology
Bonding wire is widely used on LED, semiconductor integrated circuit, and as civilian consumer goods IC: computer, mobile phone, on the chips such as television set.Industry IC: large server, motor, intelligence instrument instrument, holder, the chips such as medical apparatus and instruments, and photovoltaic, the Electronic Packaging such as diode triode.
Along with the development of market and technology, chip functions constantly strengthens, lead-in wire is more and more, and volume is more and more less, pad area ratio shared in whole chip is caused constantly to rise, therefore, Studies of The Superfine spacing bonding techniques solves the miniaturized key technology that must solve of chip, but the performance of this kind produced in the market and thin bonding wire still compares poor, basic reason is that the design of mould is reasonable not, cannot complete operation, mold material selection and material mixture ratio thereof all can not obtain rationally simultaneously.
Summary of the invention:
It is reasonable that technical problem to be solved by this invention is to provide a kind of methodological science, the flat molded Preparation Method of preparation technology's super thin noble metal extruding simply and easily.
Technical problem to be solved by this invention realizes by the following technical solutions:
The flat molded Preparation Method of a kind of super thin noble metal extruding, is characterized in that, comprise following processing step:
A, select high-quality rough diamond to be raw material, the rough diamond raw material chosen are had openning hole through micropore laser machine specification as required, for subsequent use;
B, take stainless steel compound, comprise in compound nickel, titanium, chromium, Tong, ?, the interior nickel of compound, titanium, chromium, Tong, ? proportion be 18:9:1:12:8, be then processed into overcoat base by metalworking workshop, for subsequent use;
C, the rough diamond had openning hole through micropore laser machine specification as required handled well by step a adopt adhesive glue maxxaedium as inner core, then after bushing welding powder, in the overcoat base prepared by the progressive rapid b of high pressure bushing machine edge;
D, be then processed into coarse semi-finished product with ultrasonic wave and draw point after, carry out refine, coarse semi-finished product ultrasonic wave selected diamond mould powder carried out retrofit to required specification;
After e, steps d process terminate, adopt polishing machine be processed into further high accuracy semi-finished product then further in-depth be processed into finished product, pack after oil surface.
The invention has the beneficial effects as follows: present invention process flow process is succinct, reasonable raw material proportioning, with pure stainless steel for shell and rough diamond are for heart, ensure that its internal fine, can prepare easily for meticulous lead-in wire, the flat moulds of other irreplaceable extruding metals, the manufacture of various noble metal flat filament band can be widely used in, e.g., gold, other noble metals such as silver, platinum-rhodium wire, aluminium silicon, single crystal Cu, are convenient to promote and use.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
