Method for fixing small column-shaped metal body arrays

Abstract

The invention discloses a method for fixing small column-shaped metal body arrays. The method comprises the steps as follows: (a) regularly inserting the small column-shaped metal body arrays (1) into a paraffin layer (2) and exposing root parts (4) of small column-shaped metal bodies (3) to the surface of the paraffin layer (2); (b) plating the surface (5) of the paraffin layer, to which the root parts (4) of the small column-shaped metal bodies (3) are exposed, with a metal layer (6) having certain thickness; and (c) removing the paraffin layer (2) by melting. According to the method, low-cost, soft and easily-molten paraffin is taken as an early positioning medium for the small column-shaped metal bodies, the column-shaped bodies are fixed and bonded through low-temperature metal electroplating or chemical plating, the operation is simple, the technological process has small force and heat effects on the small column-shaped metal bodies, the fixing operation is efficient and reliable, the cost is low, and mounting and fixing problems of the small column-shaped metal body arrays are satisfactorily solved.

Description

technical field [0001] The invention relates to a method for fixing and installing a columnar body array, in particular to a method for fixing a metal tiny columnar body array. Background technique [0002] In the practice of industrial production and scientific research, it is often necessary to regularly fix several metal micro-pillars together to form an array to achieve certain specific purposes. For example, bioelectrode arrays for measuring biological signals. Another example is an EDM / ECM columnar electrode array or a mechanical stamping head array for forming tiny group holes. Due to the small size, low rigidity, and often large number of metal micro-pillars used in the above practice, it is extremely difficult to effectively and reliably fix them regularly and form an array by conventional methods. "method" to manufacture these metal micro-column arrays, such as EDM reverse copy method, electrolytic machining reverse copy method and wire electric discharge wire cu...

Problems solved by technology

Due to the small size, low rigidity, and often large number of metal micro-pillars used in the above practice, it is extremely difficult to effectively and reliably fix them regularly and form an array by conventional methods. "method" to manufacture these metal micro-column arrays, such as EDM reverse copy method, electrolytic machining reverse copy method and wire electric discharge wire cutting method, etc.

However, due to the above-mentioned manufacturing method, which is particularly affected by factors such as flow field, electric field, and processing product exclusion, it is impossible to achieve uniform distribution of flow / electric field and efficient removal of processing products when processing metal micro-columnar bodies. In addition, the processing gap is small. The control factors are complicated, and the small metal cylinders produced and formed are often of different sizes and lengths, which seriously affect the use effect

Obviously, the method of fixed integration after single-piece manufacturing can largely solve the geometric shape and size differences between the individuals in the array of metal micro-pillars, but how to make these tiny metal columns that are easy to be stressed and deformed by heat reliable And it can be fixed and integrated to form an array with mutual conductive connection, which is very difficult
