Interface Definition for TTL Card
TTL Card is used to stablish the communication between PC and Handler
T1—T5 Setting
•T1 is the delay time of sending out BIN signal after the test finishes. The process needs no delay time usually (Suggest setting 0) •T2 is 1ms longer than T4 at least, and make sure T2 cover T4 (Handler determines the width of T2 and T4) •T3 is suggested to set between 0 and 1ms, in order to send BIN signal before EOT signal •T5 is the delay time between BIN and the next SOT (decided by Handler) •T5 is slower than Handler‟s operating time
Introduction:
•BIN : product classify information
•EOT: end of testing •SOT: start of testing
BIN and EOT are output signals（TTL Card set out to Handler） SOT is input signal（Handler set out to TTL Card） figure1

Interface & Setting for Handler
TTL Card Fuse
TTL Card Fuse is 0.5A
Note: If handler offers 5V itself， 5V port of TTL Card must not connect Handler .Or else it will break TTL Card Fuse
Mapping Settings Description(Ⅱ)
LocationCode select”5-8”, the setting relationship between DIE and SITE as left picture.
Mapping Settings Description(Ⅲ)
Mapping Settings Description (Ⅰ)
Tick it , then be set. Location Code: used to set the position relationship between DIE and DIE, DIE and SITE. By drop-down menu to select, the following detailed description
Export Setting button is used to save handler configure
Signal Debug Setting
1. Site and BIN choice
2. Relay time after receive the SOT
3. single test 4. Circle test
Die Size Setting Description
Tick it , then be set. WaferSize: used to set the size of Wafer through the drop-down menu. Width(Y): Set the width of DIE, units of mm. Length(X): Set the length of DIE, units of mm.
Multi-Site Synchronous Wait Time
Synchronous wait time: It is the reservation intervals after
receiving the SOT(1) during the multi-site test . If tester receives the new SOT(2) during the interval, Tester will test the sites which received the SOT(1) and SOT (2). Example: When we run a quad-site program, after receiving the first SOT(1) signal (site 1),Tester receive another SOT(3) in the synchronous wait time .Test Site(1) and Site(3) only. Note: When testing in multi-site (assumed dual site , synchronous wait time is 20ms),if TTL Card received two SOT signals in less than 20ms ,Tester run right now (NO waiting to 20th ms) .
SOT Signal Setting
Setting mode is decided by the SOT signal of Handler. If the effective signal is low level, select “Negative Logic”
SOT is low level
5. Stop test
6. Selected, tester send SOT by itself, and automatically send EOT & BIN. Interval is decided by (2)
7. Clear the window

EG Prober Connection Setting
Test Site: Station number, it‟s the test DIE number at the same time. Set it through the drop-down menu, including 1,2,4,8,16.The number should be consistent with the median of probe cards work. Address: The hardware address of the probe station.
Location Code select”9-12”, the setting relationship between DIE and SITE as left picture.
Mapping Settings Description(Ⅳ)
Coordinate Code: Used to set Prober X, Y axis direction of growth through drop-down menu, corresponding increase in the direction of the content as shown on the left picture. Mobile CHUCK, the focus Prober provided on the display X, Y coordinates, which can confirm the direction of its growth.

TTL Card Driving
Pull out and insert TTL Card will make TTL fail , suggesting to install TTL driving again
Location Code select”0”, corresponding to a single station set; Location Code select”1-4”, the setting relationship between DIE and SITE as left picture.
TTL Card Defining of Dual Station
If system configuration is Dual Station, there are two TTL Cards, upper for STATION-A, below for STATION-B
