標題: 靜電放電測試 [打印本頁] 作者: ritafung 時間: 2008-4-12 12:55 AM 標題: 靜電放電測試 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?作者: m851055 時間: 2008-4-12 08:07 AM
竹科閎康科技有此業務2 v9 e& h1 h5 x5 h8 s6 s

For ESD test (HBM) / z w: e% I7 H. {# R5 S% lThe following are the test combination: # N2 g8 q- V+ j `* \1. Power to Power + o! }4 {1 N6 V! z; l2. Power to Ground 4 u' I! t7 J1 ^4 k3. IO to Power ; u7 F# ~( l& U7 O; [2 F, ?3 t9 h4. Io to Ground ) U' s+ {7 y8 o; I5. IO to IO9 S! m' M# Q; Z$ G! A
(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.)7 P' \9 d* H! U$ n- Y! H

So for high pin count it will take a lot of time. But it won't take more than a week(for one chip). / R9 X. M: ^: a0 R% [) H! ^- Z* `( d/ Q( A! [* \& Q

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?? & r. V3 i8 O) ^0 [4 ?5 x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~作者: ritafung 時間: 2008-5-26 09:15 PM
thanks wesleysungisme for your answer. m5 L9 F, P0 C5 y/ c9 @ s0 ?as our pin count is over 1000 and no. of power is ~ 20, so it's quite time-consuming. {$ V; I: w; Land 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.
