Embodiment Construction

[0164] like Figure 1-4 , the DC-DC power supply module selected by the present invention is a high-reliability DC-DC converter of a certain type, which adopts a push-pull structure and can work at an input voltage of 28V, with a maximum power of 45W. The circuit shell is fully sealed with metal Structure, without fixed terminal, adopts single-layer thick film substrate, does not use chip assembly technology and multi-layer wiring process, due to insufficient space, the circuit adopts component stack welding process, and the circuit adopts the process of welding aluminum sheet on the substrate, Avoiding the gold-aluminum bonding point on the aluminum wire in wire bonding, combined with specific actual cases, a method for evaluating the technical maturity of a DC-DC power module according to the present invention is described in detail, and the method flow chart of the present invention like image 3 As shown, its specific implementation steps are as follows:

Abstract

A method for evaluating the technical maturity of a DC-DC power supply module, the steps are as follows: 1: Construct the technical maturity evaluation system framework of the DC-DC power supply module; 2: Establish a technical maturity evaluation model for the DC-DC power supply module; 3: Calculating the technical maturity of DC-DC power modules: get the maturity measurement value of the technical elements of technology dimension, material dimension, design dimension and manufacturing dimension, so as to calculate the technical maturity of DC-DC power module, and then its technical maturity The results are analyzed and evaluated; the invention provides decision makers with quantitative data support, comprehensive evaluation parameters and high reliability. Using the KPA evaluation method, it is concise and easy to operate, and can calculate and evaluate the technical maturity of DC-DC power modules, which has the value of popularization and application.

Description

(1) Technical field: [0001] The invention relates to a method for evaluating the technical maturity of electronic components, in particular to a method for evaluating the technical maturity of a DC-DC power supply module. It is a combination of Analytic Hierarchy Process (namely AHP) and key process area method (namely KPA), to build a technology maturity evaluation model, to calculate the technology maturity of direct current to direct current (namely DC-DC) power module, and thus to its The method for evaluating maturity belongs to the field of technology maturity evaluation of electronic components. (2) Background technology [0002] In recent years, with the rapid development of military technology and weaponry in various countries, not only the demand for electronic components is increasing, but also the reliability requirements are getting higher and higher. However, at home and abroad, there are more researches on the technical maturity of systems and equipment, and ...
