Span length 2. span Angle corr3. 2nd kink smoothness4. 2nd HT Factor 5. Last kink Bump Factor 同左3rd kink parameter 1. slope length 2. contact Angle corre

2、ct3. 3rd kink smoothness 4. Twist motion Motion parameter 1. Y-compensation (%)2. Loop Top Above 1st bond 3. Y-compensation delay 4. loop top Dec sample 5. loop Time offset 同左同左Reverse Motion 1. 1st reverse Mode Linear 1. 1st Rev. Mode 2. 2nd Rev Mode linear 1. 1st Rev Mode 2. 2nd Rev mode 3. 3nd Re

4、HCRDALHRDRHLHC (loop height correct ) 2nd kink parameter 6. span length unit ( % , um , mil , Sum , Smil , Aum , Amil )Span length Remark : a. % =% of wire length b. Span length um , mil = fix Span length Slope length c. Sum, Smil =fix slope length d. Aum , Amil = 從pad 作平台至die 的邊緣處，開始計算Aum 的補償 (如選擇A

5、um ，Amil 其software 會自動要求設定die 框) 適用於 die pad 與die elge 距離不同 AumAum2.span Angle correct (Flat , Slan ) Flat與Slan 之差異: Flat Slan 1st kink = 2nd kink 1st kink height than 2nd kink -Ve+Ve-Ve+ VeSpan Angle Correction =03. 2nd kink smoothness =-30% =0% =30 % 4. Last kink Bump Factor 3. Span Length RHRDSpa

6、n angle +span angle correct RD2 (由S/W計算)5. 2nd kink HT Factor 原理: 其原理同wire length factor 以下用wire length factor 作說明 close close LHC=+Ve close LHC= -Ve WL WL WL LHC=0 LHC=2 LHC= -2Total WL = ( WL + WLF ) + LHC 例: 在同一group 中比較不同WLF其實際線長有何不同，其變化為何 LHC 1step =10umWireWL(um)LHC (um) WLF (%) Total WL 11000

Slope length 定義：slo

8、pe length 為最後一個kink 之說明，故只針對最後一個kink Slope length Slope length 2. contact Angle correct Contact angle Correct 50 more 3rd kink height R 故在拉弧時可能擠壓，造成倒線If Bond Top above 1st bond 選六linear , convex 因其動作移至R 位置，其依等半徑運動，比較不會多放線3. Loop Top Time offset Y compensation Pre Delay Loop Top DEC sample Convex Y c

9、ompensation pre delay Linear If loop top above 1st bond convex 則 Y compensation pre delay =10 (default ) Linear =04. loop Top DEC Sample default setting =255. loop Top Time offset 此功能原理同sync offset Remark : If bond top above 1st bond 選Convex loop top DEC Sample =/= 0 (S/W自動計算) loop top Time offset =

10、/=0(S/W自動計算) Y compensation pre delay =/=0 (須手動key , default =15) Idea 實際實際Idea Trajectory parameter 注意：採用manual Tuning 其實際曲線須在idea 上方，否則會線弧不良例：採用manual Tuning 時, 可用此功能預先觀察looping 此圖可看出sync offset , DEC 可能發生錯誤因為此區低於idea 值 Pull Motion W/C open 2nd search height WLNo Pull motion BHXY table no move Pull ratio XY table Vertical pull level & Time BH pull Ex : If WL =1000Pull ratio =25% , 則試計算，pull 多少距離Pull Ratio =25% x (0.1) =1.5% of WL =(2.5/100) x 1000 =25um Remark : If pull Ratio 2nd bond SH 會導至滑針 Feed Power USGEnding USG Ending USGEnding Time =20 Time=20 Time =20
