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.
, N/ p- J# ]  l* m& B+ b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

測試多Pin需要花費時間比較長久，可是你們HBM是使用JECDE

my company is pursuading to MIL-Std ...
actually any company need MIL-Std? Our application is not for military purpose....

For ESD test (HBM)
The following are the test combination:
1. Power to Power
2. Power to Ground
2 P! a, t! o9 Z7 J1 y, x3. 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.)

- D: h$ G# ^0 r' w: U3 A$ Pthe 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)

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.
" r0 R! k2 P  ]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.
