Microwave Oven AC Noise and ESD TEST

A. AC Line NOISE ( common mode ) : + Loads / Microwave oven operationally.
一. Impulse noise simulator test condition :
1. Noise output voltage : +-1200Vmin. ~ +- 2000Vmax.
2. Pulse width : 50ns/100ns/200ns/250ns/400ns/1us max.
3. Line phase : 90∘/ 270∘.
4. Variable : slow ~ fast.
二. Loads :
把1000g +-5g的水倒入到空試驗用容器中,測得實際倒入的水質量,把試驗用容器立即放到微波爐內腔的擱架上,擱架處於微波爐內腔中最低正常位置,接通電源.
B. AC Line NOISE ( Normal mode ) : + Loads / Microwave oven operationally.

一般OTP 與Mask版本差異的主要原因及改善方式 :

一般OTP 與Mask版本差異的主要原因及改善方式 :

1. I/O sink 與driver current 因製程不同所產生的差異:

透過Standard IO 制度的建立, 往後將可選擇最接近的IO來改善此一狀況.

2. 單一OTP產品支援多種近似mask時程式相容性的問題:

先由Spec 差異表列出OTP與Mask 差異, 再由 Application Note 列出程式注意事項. 最後再由ordering form 做最後確認.

3. 相同function , OTP與mask結果不同:

若是差異可利用軟體解決者, 則在Spec中將提出軟體寫法; 若是無法由軟體避免, 則將差異詳述於Spec中.

4. Electrical Characteristic:

Spec中僅列出該產品規格.

5. 產品改版造成的差異:

由Spec history 敘述每個版本之間的差異.

6. mask 產品改版處理流程:

RP前: 更新客戶SPEC, 並註明差異.

RP後: 更新客戶SPEC, 註明差異, 請客戶針對修改部分做程式修改,並重新投OTP與mask code.
