Abstract
- Quality built-in Computer Aided Process Control
is very important for the Electronic industry to stay the competitive
advantage. The purpose is to maintain and achieve the target of six
sigma quality levels. The paper presents the total quality improvement
in a closed loop model that reflects the management and operational
personnel to ensure the continuous improvement to perfecting the quality.
The four main components of the model are:
-
- 1.) Pyramid effect program
- 2.) Building a SPC learning organization
- 3.)Internally and Externally focused quality
- 4.) Real-time quality feedback by computer aided
process control that is the main study to improve the manufacturing
process and achieve a high process capability index (Cpk & gt;
1.33) for all critical parameters.
- The four synthesis best suited to address downstream
activities include those goals to manage:
-
- Computer networking, equipment interfacing,
and real-time program multi-tasking as critical resource development
- Strategy and policy issues relevant to employee
and management involvement of total quality system
- Operation of closed loop process control
of internal and external customer/supplier concept
- System implement dealing with the integration
built in computer aided proecess control.
- The purposed project is being implemented and tested
at Advance Micro Device (Thailand) ltd. The expected results can provide
the additional insight into the quality management in the computer
and engineering management field.
- Objective
of the study
- The overall objective is to study the entire
process control with computer technology and statistic methodology.
the study has some specific objectives that are listed as follows:
-
- Study the current statistic principle for
process control of each manufacturing steps.
- Developing an automatic SPC using an up to
date computer technology and statistical process control technique.
- Study the results that effects to the automatic
SPC chart implementation
- Scope of study
- This study is confined to a particular manufacturing
process of integrated circuit assemble which produces PLD and NVD
product with variable process specification.
- Non-Volatile Memory and Programmable Logic
- NVD ( Non-Volatile Memory Division ) the Non-Volatile
Memory Division manufactures a broad range of high performance EPROM
and Flash memory products. Unlike volatile memory which loses data
when power is turned off, non-volatile memories permanently store
information. This is critical for applications such as desktop and
portable computing, electronic games, memory cards, medical instrumentation
equipment, cellular phones, laser printers and many others. AMD NVD
products include EPROMs (Eraserable Programmable Read Only Memory),
OTP (One Time Programmable ) EPROMs, ExpressROM devices and Flash
memories. Flash memories have become an increasingly attractive alternative
to other types of memory chips.
- PLD ( Programmable Logic Division )
- Programmable logic devices are part of the
glue that makes electronic system operate coherently. Microprocessors
and microcontrollers may form the brains of an electronic system such
as computer, but that brain will be useless without the nervous systems,
and its neurons and synapses that carry the brain's messages to the
body's muscles, eyes, ears, and other operational centers. Programmable
logic devices are important parts of the nervous systems of modern
electronic systems.
- What distinguishes PLDs from other electronic components
is the fact that designers themselves decide what functions a PLD
will perform, and usually also program the devices. Because PLDs are
programmable, they give system designers an unparalleledamount of
flexibility and freedom in their work. And they allow manufacturers
to change key system components almost immediately to meet shifting
market demands. AMD is manufacturing a variety of PLDs ranging from
4.5nc to 25ns.
