Title:
APPARATUS AND METHOD FOR COMPUTING LOAD
Document Type and Number:
Japanese Patent JP2008241432
Kind Code:
A
Abstract:

To appropriately compute loads of electronics substrates.

Detection values of a sensor for monitoring the state of an electronic component mounting board to which electronic components are mounted and performance characteristics acquired by a tool for monitoring the performance of the electronic component mounting board are acquired as monitoring variables. Intermediate variables are determined, from a first statistic model which is any one of a regression model for determining intermediate variables from the monitoring variables, an occurrence frequency distribution on the monitoring variables and the intermediate variables, or a probability distribution on the monitoring variables and the intermediate variables, and the monitoring variables acquired by a variable acquisition part. The physical quantities of one part or more on the electronic component mounting board are determined on the basis of a second statistic model which is any one of a regression model for determining physical quantities, on the basis of the intermediate variables; an occurrence frequency distribution on the intermediate variables and physical quantities; or a probability distribution on the intermediate variables and physical quantities and the determined intermediate variables.
