靜電放電測試

ritafung

剛剛研究了靜電放電（ HBM ＆ MM） JEDEC標準，實在需要很長的時間去進行測試。假設該IC具有數以百計的pin，很可能將需要超過1個月完成整個測試。這裡是否有任何人負責做ESD測試？

竹科閎康科技有此業務
電話在網頁就查的到了.......................

很多實驗室好像都有,但都在台北.
儀特好像就有可以去查ㄧ下

目前新竹地區有"宜特"與"閎康"兩家比較大

For ESD test (HBM)
The following are the test combination:
1. Power to Power
6 H' \/ ^1 E" O# v' p6 y0 N: i2. Power to Ground
3. IO to Power
4. Io to Ground
5. IO to IO
(different power domain need to be treated as different power. For ground usually you can treat as one group_silicon use substrate as common ground. But if you measure two different ground pin/ball > 2ohms. It should be seperated as 2 grond.)

the total zap time fomula will be~ 2(+/- polarity) X (IO#X(P#+G#)+IO#+P#X(P#-1)X(P#-2)X...X1+P#XG)
For example: You have IO1/IO2/IO3/P1/P2/G1
2x((3X(2+1)+3+2X1+2X1)=25(multiple the zap interval)
So for high pin count it will take a lot of time. But it won't take more than a week(for one chip).

樓上的Jason...據我所知大部分的IC設計都會跑去宜特做ESD...為什麼你要特別建議去閎康做呢??
有什特殊原因嗎??會比較適合的邏輯是什麼??是否可分享一下心得??感恩~

thanks wesleysungisme for your answer.
as our pin count is over 1000 and no. of power is ~ 20, so it's quite time-consuming.
and there is technical issue about bonding all the dies into COB for ESD zapping, i wonder if anyone could share their practise? we feel difficult to strictly follow JEDEC standard.
