How many test stations can be interfaced? |
| A. |
Standard Test System can interface two stations and as an option (at extra cost) maximum upto four test stations can be interfaced with one test system. Each test station can run independent separate test programme. |
| |
|
| Q. |
What device testing capability are provided in the standard tester configuration? |
| A. |
Standard configuration can test Diodes, Zeners, Schottkys, Rectifiers and Transistors. |
| |
|
| Q. |
What testing capabilities are available as options? |
| A. |
AC Parameter (VZ(AC) and hfe ), VCEX and ICEX, Delta Vbe Testing, FETs, MOSFET, IGBT, SCR/Triac and Voltage Regulators are available as options. |
| |
|
| Q. |
What is minimum test system configuration? |
| A. |
Minimum operational test system configuration is Tester, Manual Test Station or Handler Interface (Head Box) and Accuracy Check Unit (one per location) along with a user provided PC. |
| |
|
| Q. |
Is PC included along with the test system? |
| A. |
No, the PC is required to be supplied by the customer. |
| |
|
| Q. |
What is the required PC configuration? |
| A. |
Any Standard PC Pentium or higher, Monitor, Keyboard, Serial Port (9 pin), Printer Port. |
| |
|
| Q. |
What is operating system required for PC? |
| A. |
Windows 98 or Windows 2000 or Windows XP (Service Pack2). |
| |
|
| Q. |
What hardware modifications are done to test optional parameters? |
| A. |
For testing optional parameters, additional card(s) are required to be mounted in the tester, such as, for testing MOSFET parameters - GMP card is required; for testing SCR and Triac - three additional cards are required; for testing Delta Vbe - IE card is required. |
| |
|
| Q. |
Can we have all optional testing parameters at a time, that is, in one test system? |
| A. |
No. Three slots are available in the card cage for adding options. |
| |
|
| Q. |
How to test HV parameters up to 2.5 KV? |
| A. |
Additional hardware module is available, to be interfaced with the standard tester to enhance the test system capability to 2.5 KV. |
| |
|
| Q. |
Can we test Voltage Regulators? |
| A. |
Yes, for Voltage Regulators with maximum Voltage Input of 20V and Output Load Current 1A. |
| |
|
| Q. |
Can we save test data in Excel format/file? |
| A. |
Yes. |
| |
|
| Q. |
Will test socket(s) be provided? |
| A. |
Yes, user needs to specify the package outlines/dimensions. |
| |
|
| Q. |
What is speed of testing? |
| A. |
Tester speed depends on programmed tests and soak time. Tester takes default test time as per the test condition. Soak time for low leakage tests would be more and high current tests are tested at low soak time. Soak time can also be programmed by user from 400uS to 9S. |
| |
|
| Q. |
How to calibrate the test system? |
| A. |
The OnTest Test System does not require frequent calibration. When first installed, the accuracy of the system can be checked once a month using the accuracy checker unit. Subsequently calibration check once in six(6) months is suggested. Components used in the Checker Box are low drift high accuracy components and readings don't drift with time. Golden samples (components with readings taken on any reference Test System) can be kept for comparison purpose. However, calibration procedure for each card is given in the Operational Manual.
Accuracy checker unit has precision resistors whose value can be checked at any Standards Lab once a year so that test system is traceable to National/International Standards. |
| |
|
| Q. |
Can OnTest T-201 test surface mount devices (SMD)? |
| A. |
Yes, the OnTest Tester has three test pins available (Collector, Base, Emitter) for testing. SMD package outline specific test socket(s) has to be used for testing the Discrete Semiconductors in surface mount package(s). |
| |
|
| Q. |
Can OnTest T-201 be interfaced with Automatic Handler and/or Wafer Probers? |
| A. |
Yes, all standard makes and models of Automatic Handler and/or Wafer Prober can be interfaced with the OnTest Tester. The OnTest Tester has standard interface signals like Tstart, Tend, Bin Signals (14 parallel lines) for interfacing. |
| |
|
| Q. |
Can we test separate devices on the two stations (or four stations, with additional multiplexing option)? |
| A. |
Yes, separate devices can be tested on each station, like diodes on Station A and transistors on Station B can be tested simultaneously or different diodes or different transistors can be tested simultaneously on the two test stations. |
| |
|
| Q. |
Can we have station A with a Manual Interface and station B interfaced with an Auto Handler? |
| A. |
Yes. Station A and Station B can have any of following configurations:
- Both Manual Stations
- Both Handler/Prober Interface.
- One Handler and One Manual Station.
