: H/C optimization from modify WP process to GUMI’s one
□ separate MAIN process from RWK process
- port gap of each cell in Main process
- RWK Status : 5.5Cell / 3.5 名
□ MIAN □ RWK
□ Unify MAIN with RWK
- Unify Main Prime & RWK
- correlation the number of facility in each cell
□ MIAN □ RWK

□ WP, C/R inputting HDA process.
. Human resource was separated for two station.
. Gumi based, It is just one station and could optimize H/C.
Op : 5 名 → 3 名 , 2 名 ↓
.. B/E, C/R inputting process optimize (5 名 ) → (3 名 )
※ WP, Current 5.2M product based
→ 5 名 (4.5 名 ) Arranged
※ 6.3M Product Based (After H/C)
C/R inputting HDA Cleaning
HDA input to C/R
5 名
□ Gumi based, it could able to one operator for each C/R (D2D
1F, D2D 2F, D2E).

□ C/R inputting process optimization
※ C/R inputting HDA Cleaning + HDA input to C/R
Each C/R 1 operator arrange (6.3M Based)
. SEC (1.55M) : 0.3 名 + 0.3 名 = 0.6 名 arranged
. SEC (6.3M) : 1.2 名 + 1.2 名 = 2.4 名 arranged
. W/P (5.2M) : 3.5 名 + 1.0 名 = 4.5 名 arranged
→ About 3 operator could optimize.
And more reduction of inputting HDA cleaning is need to more discussion.

□ WP, PCBA Rework Process.
. Separated PCB Code D/L process,
PCBA VMI (PCBA Discolor repair)
and PCBA dispose process.
. So, each process arranged operator.

□ WP, PCBA Rework Process improving.
. From the Gumi site based,
PCBA VMI operator control the PCBA dispose process.
( effect : 2 名 → 1 名 )
. cf.) Gumi has not issued PCBA discolor, so VMI process

□ B/E PCBA Process optimization
1. W/P site : Each PBCA Rework process separated.
- PCBA T/D
- PCBA code D/L
- PCBA discolor repair and VMI
- RTV PCBA & MRB material dispose
2. Gumi site : For efficiently operating, some process has combined and simplified.
- PCBA T/D
- PCBA code D/L and VMI
- RTV PCBA & MRB material dispose
※ Gumi has not issued PCBA discolor, so VMI process has combined with PCBA D/L station.
3. From the Gumi’s resource standard, RTV PCBA & MRB material dispose operator has arranged 1 operator.
4. PCBA D/L machine : Need to study for its efficiency (D/L Port increase & Code D/L speed up, etc)
5. Discolor issue : Need to study of root cause for its process removal.
