KAIZEN
DIRECTIONS FOR AUTOMOTIVE ELECTRONICS PRODUCTION
1. Eliminating
Defects in the Devices (Semiconductors, Electronic Parts, Boards and
Sensors etc.)
- Much of the total volume of electronic devices is not self-manufactured
but purchased.
- QCD Improvement comes from the engineering ability of Tier 1 manufacturers.
- Kaizen in the Circuit Design greatly increases the level of QCD
improvement.
2. Eliminating
Defects in the Device Solder-Mounting on the PCBs (Printed Circuit
Boards)
- These are the most serious problems in the ECU manufacturing process.
- QCD Improvement comes from improving operators' soldering and mounting
skills.
3. Eliminating
Defects in the PWBs (Printed Wiring Boards)
- Much of the total volume of printed wiring boards are purchased.
- QCD Improvement comes from the manufacturing ability of Tier 2 manufacturers.
- Kaizen in the Board Design greatly increases the level of QCD improvement.
WHAT
CAN GO WRONG IN QCD IMPROVEMENT

STEPS
FOR QCD IMPROVEMENT
[Quality Statement]
Quality is created in the manufacturing process. If the causes leading
to defects are eliminated beforehand, the burden to eliminate defects
are not passed on during the respective processes.
[Procedure]
| Education
& Training |
|
1
|
Check
the on-site data. Analyze the emerging pattern. Understand why
defects come out. [Literature Review]
- Experiment Design & Data Survey.(Refer to Fig.1. as below)
- Practical Use of Test Boards. |
|
2
|
Visualization
of Defects.
- Practical Use of your Digital Camera. |
|
3
|
Microscopic
Observation of Faulty Points.(Refer to Fig.2. as below)
- Practical Use of Analysis Tools (e.g. Microscope) |
| Cultivation
of Self-prescription |
|
4
|
Feedback
Nonconformance Reports to the Mfg. Process.
- Accumulation of Fault Examples |
|
5
|
Revision
of Checklists & Manuals on site. |
|
6
|
Launch
the Site-Remediation Movement.
- Review the Authority & Time Allocation of Operator
- OK if "Shorter working hours" less than "Existing".
|
|
7
|
Follow
up the Improvement Actions. |
|
8
|
Supervise
the Tier 2 Suppliers' Improvement Actions.
- Defects in Board Manufacturers have large influence. |

EXAMPLES
OF THE DELIVERABLES
Assessment
Reports
(on individual site)
|
MarkLines
will document the results of survey, on-site assessment, and cause-and-effect
analysis and the Manufacturing Implementation Plans for the individual
site.
|
[Contents
of the reports (examples)]
- Manufacturing process flowchart
- Cause-effect diagram of problems
- Solutions & Implementation
- Improvement Results etc. |
Manufacturing
Technology & QC Checklists
(on individual Mfg. process)
|
Since
there are determinants of the quality for every mfg. process,
MarkLines will improve the checklists used on site, which will
be more useful for the improvement on manufacturing technology
and quality control. MarkLines will teach the fault analysis theory
and practices to key persons and operators, who can do improvement
activities spontaneously by themselves.
The documented record of MarkLines instruction activities is a
deliverable.
