CASE STUDIES (DIAG. TOOL)
Case studies by usage
PC Manufacturer C
"QuickTech Professional" installed
- Cost reduction of quality control & lower defect ratio
- Information sharing by using same tool with customers
PC manufacturer, company C has used her own developed diagnostic tool for current product inspection in manufacturing process.
She has felt her own tool cannot satisfy requirements because new product development cycle time has been shorten
based on recent faster technology revolution speed and frequent customer requirement change.
In addition, defect detection ability has not been enough though diagnostic
tool development cost has been increased. Now cost reduction and defect ratio reduction have become top management priority.
By using QuickTech Professional,this company could
reduce quality assurance cost drastically. In addition,
defect ratio could be reduced.
Internal developed diagnostic tool is "Confidential" and it could not be used at customer site.
QuickTech Professional is free from such control. By using the same
tool at customer, testing with the same standard is possible both the company and the customer.
It also leads customer satisfaction increase by sharing the same test data.
White Box PC Manufacturer F
"R.S.T. Pro 2" installed
- Returned system has been reduced day by day.
- After 3 months of installation, defect caused by memory became zero.
Company-F has started to sell new BTO computer which accepts memory configuration
change based on customer request.
After first shipment, many claims, "system unstable", have arrived and it became hard to handle shipping operation
due to customer claim management for the defect.
Based on failure analysis of collected systems, the cause was on memory module.
Memory module, however, has been worked well on mother board for evaluation. In some combinations, its unstable symptom has been detected.
Then they have added memory test using R.S.T. Pro 2 at inspection process before shipment.
As a result, returned PCs has been reduced day by day. And
3 month after of process change, return by memory defect became zero.
PC Manufacturer D
- Users can run diagnostic program by themselves.
- As a result, support cost could be reduced drastically.
PC Manufacturer D's profit has been compressed due to PC price reduction trend and customer support cost increase though their customers have been increased year by year.
Support cost reduction was Company D's top priority.
By embedding UltraPOST diagnostic tool in their PC,
their customers became to run diagnostic program when trouble is occurred at customer site.
Since it has ease of use icon interface
, customer can check if the trouble is due to hardware failure or not. Then the manufacture D became not to collect systems without hardware failure.
Call center also became to know customer's failure status and the tool could lead to
reduce calling time per customer and save telephone line fee
. As a result, drastically support cost was reduced.
In addition, since UltraPOST is embedded tool in system, it never been lost by customer..
Requirement：To shorten development period, To detect error speedy or To focus Memory testing
For new product development, wide variety of commodities such as CPU, memory, HDD, chipset and so on,
should be tested and their combinations needs to be tested also. Recent business cycle requests shorten development period
and Ultra-X's diagnostic tools are very important for effective commodity qualification and compatibility testing.
As same as bus analyzer or synchroscope, Ultra-X's "P.H.D. PCI 2" (Professional Hardware Diagnostic) and
"R.S.T. Pro 2" (RAM Stress Test) have become "must item" for development engineers.
For example, P.H.D. PCI 2 has three diagnostic modes. "P.H.D. mode" tests hardware at chipset level.
"Extended mode" tests commodity like CPU or memory.
"Forced mode" can test system even without memory.
Especially "Forced mode" is strong and it can be used for mother board testing without BIOS or system test which OS cannot boot.
Requirement：To improve manufacturing quality, To perform effective inspection in short time or To automate inspection
Yield improve, Process standardization, Effective procedure, and so on.
Computer manufacturing organization is facing many issues to solve.
Especially commodity combination issue is non-avoidable and hard to solve item. it is easy way of thinking that such test has been completed in developmentphase.
In manufacturing process, there are some quality confirmation stages like parts receiving inspection, assemble, inspection, aging and shipment.
With effective quality control for each stage, total system quality is secured.
"QuickTech Professional" has ability to detect commodity combination issue effectively.
And it can be used for aging process also. "QuickTech Professional" has self testing mode called as Burn-in script.
It can designate test contents, sequence and time as required. Repeat test for specific period makes stress to computer system and hidden issues could be detected.
In case monitor is not prepared for each test systems in manufacturing process, Burn-in status can be notified using keyboard LED blink for example.
Requirement：To solve customer issue quickly, To standardize operation or To have common diagnostic tool in company
Ultra-X's diagnostic technology has focused on development and manufacturing purposes, but it has been used in support field.
Good example is system embedded technology "UltraPOST".
Since it is stored in BIOS on mother board, diagnostic is possible if OS does not boot due to HDD trouble.
In support business, it is necessary to get customer error symptom correctly and quickly.
For the purpose, it is very important to identify if the cause is on hardware or software.
"UltraPOST" can be used by customer easily, they can do self check.
Operator in support center can ask customer test result of "UltraPOST" and guide correct solution way.
In service and support field, Ultra-X's diagnostic tool is convenient.
It can be used not only in repair center, but also onsite repair or maintenance at customer site.
Requirement：To reduce education cost, To check specification easily or To have same process among shops
Based on "Law for the Promotion of Utilization of Recycled Resources" from October 2003,
PC recycle has been started officially for consumer personal computer too. With the trigger, in addition to existing recycle service company,
PC manufacturer, consumer electronics shops, etc have joined recycle business. Ultra-X has provided "QuickTech 3R"
as recycle business solution before the law. "Quick test in 5 minutes", "Ease of use"
and other features focus on recycle are available. Once "QuickTech 3R" is started, hardware testing,
specification confirmation, I/O device testing like keyboard and display, and other testing can be performed.
Using this tool, operator can assess and purchase operations without special skill and it is possible to reduce education cost
for specialist of such operations. Total recycle process can be covered by Ultra-X's solution to add "QuickTech HDD Clean Pro",
"QuickTech Professional" and "W.S.T."
