Kingpak Corp's main production is CMOS image sensors. Over the past 5 years, they have built up their internal image sensor testing capabilities by: 1) Designing and implementing their own auto image test systems using self-designed test kits, software, and an auto handler. 2) Working with customers to define image specifications and test requirements. 3) Saving costs by developing their own test equipment rather than outsourcing, reducing the cost of test sets from NT$500K in 2006 to NT$50K in 2012.

1. Kingpak Corp.
● Main production is CMOS sensor
component.
● Currently responsible for contact w/
customer for realizing and meet their
test requirements. Also need to
coordinate 5 engineers (H/W and S/W)
to accomplish the job.
● My subject is to provide a stable, reliable
and automatic image test system for
customer

2. In 2006, the image sensor test status
● Inspect by eyes
● Out sourcing SW
● Purchasing test system
● As AMIDA test system

3. Present, Test system
● Self-designed test kits
and light box
● Self-designed image
test SW
● Self-designed auto
test system by
Handler
● Build up image
laboratory

4. What progress during 5 years?
● Saved the cost of test equipments

7. What have done for this change?
● Built up Kingpak CIS test
capability for Mass production
● Designed and implemented CIS
auto handler test system.
● Conduct test system to backend
stage of mass production.
● Correlated w/ customer for
defining image specification and
requirements

Example :
Defect Test Definition:
• Dead Pixel, < > 30%.
• Wounded Pixel, Btw 30 ~ 15%.
• Line Defect, <> 30%.
• Cluster, Btw 30 ~ 15%.
• Blemish, <> 14 ~ 4%.

11. Designed and implemented CIS auto handler test system
● Collaborate w/
handler vendor to
extend semi-auto
test system to full

14. Air meter products
● Due to the quality of air is a
huge matter for the human
health, so people think
there’s an air indicator to
alert bad condition is more
important issue.
● Our development are from
sensor module, MCU
selection to firmware
coding and algorithm
derive.
● Currently we have
developed TVOC and
Alcohol Meters.

15. Bio-Meter products
● Health is important.
Most way to know the
health is by blood.
Through it there are
many indices show the
status of Health.
● Currently we focus on
developing Glucose
meter. Due to the more
and more diabetes
patients, the meter can
help them to control
meal.
