Abstract:
The purpose of this independent study is to examine the sequence of influence factors in tooling
maker selection for electronics manufacturing companies. The study was focused on the influence
factors in tooling maker selection which were used for electronics manufacturing companies and
requires high precision tooling for their processes. The precision of tooling requires tolerance
between plus minus 3 microns (plus minus 0.003 millimeters) to plus minus 100 microns (plus minus 0.100 millimeters)
which requires high performance machining processes and ordinary machining processes respectively. Such the
precision, some of electronics manufacturing companies classified their suppliers based on the
tolerance defining in drawings due to the different in precision control and process limitation of
tooling makers. The tolerance between plus minus 3 microns to plus minus 5 microns was defined as class 3, The
tolerance between plus minus 5 to plus minus 100 microns was defined as class 2 and the tolerance more than plus minus 100
microns was defined as class I respectively.
The result of this study is determined based on the data collection from 3 departments of 10
electronics manufacturing companies. they are procurement, quality control, and engineering
departments. The result suggested 27 factors were influenced in tooling maker selection. Top 3
factors were concluded based on the data collection, procurement and quality control departments
defined quality, delivery, and price as extreme importance factors respectively. Engineering
departments defined modem technology, quality, and price as extreme importance factors
respectively. The result from this study are suggested to be used as a business guide line for tooling
makers to develop their organization in the future.
