QG What is ICTH AG ICT, In Circuit Tester, is an auto-testing equipment of assembly board. It can detect most of manufacturing defects of PCB assembly. QG What devices can be tested by ICT? AG Resistor, Capacitor, Inductor, Diode, IC Clamping Diode, Open or Short defects and so on. Also, by adapting TestJet technology, ICT can detect SMT IC pin open defect. QG Is ICT a kind of meter? AG ICT is a kind of auto-high-performance meter, and it can measure precisely the actual value of each device because of its guarding function. QG What's the difference between ICT and meter? AG Meter tests only one independent component, while ICT can test all the components on the assembly board via fixture. However, ICT needs Guarding function to have testing more accurate. QG What's the difference between ICT and ATE? AG ICT is Power Off testing, and it means there is no power applied on assembly board. ATE is to test if the components on assembly board function well, so the board should be powered on. Especially when ATE is sending signal, the component's characteristics should be concerned or it may be damaged.

QG ICT Press unit acts normal before computer been changed, but why after changed, press unit cannot work, while the main set self-check is OK. AG It is because IRQ 10 is conflicted. In BIOS, IRQ10 should be assigned to ISA, if using Windows version, you should set IRQ10 as "reversed" in system. QG The computer is almost with PCI Slot now, so can my ISA DIO card be upgraded to PCI DIO card? AG The PCI Digital I/O card of 518 series is available now. QG When using windows version ICT software, and why the computer happens to break down after testing is hold for a while? AG It is because the computer execute power saving. It maybe:1.The "Power Manager" is not set "Disable" in BIOS.2.The "Turn off monitor" and "Turn off hard disk" are not set "Never" in Power Schemes. QG Is it possible to have sound alert for the testing result? AG In Windows OS, it is only need to add sound card and speaker to your computer, and the good or defective one can be identified by sound. QG Can the Dos version ICT system software be upgraded to Windows version? AG TR-518FE&FR can be upgraded to Windows version without compatible problem, but DIO card needs to be changed if the main set platform is TR-518F.

QG Should the main set of ICT be calibrated regularly? AG ICT will self check when turned on, so it is no need to be calibrated. Also, ICT is to check short, open, component error, missing and so on, and the precise value is not necessary. Thus, ICT emphasizes the comparing value not actual value. If the user requests to have calibration, TRI still provide the service and report. QG If I want to use Agilent TestJet technology to detect SMD IC open, what hardware should I buy? AG The hardware needed includes IC Open Test Control Board, Mux Card, and TestJet License. QG What kind of hardware should I buy for testing Crystal? AG Counter Board and Universal Buffer Board. QG I want to have auto-stamping function, but don't know how to jump and connect the wires. AG 518F JP8 ON, JP1 OFF. 518FE JP2 ON, JP5 OFF. 518FR STPA ON, TLTA OFF. Connect the valve's positive end to +24V and the other end to the 9th pin of D-Type. QG How to jump and connect the wires if using photo senor protecting function. AG 518F JP2 ON, JP6 OFF. 518FE JP6 ON, JP1 OFF. 518FR INFA ON, MSWA OFF. Photo sensor's signal source connects to +24V and ground signal to ground pin and the other to the 12th pin of D-Type.

QG If my DUT can be connected to switching board without fixture, how can the board be tested without press unit? AG You can use F5 (Keyboard) to execute testing, but the Fixture Type in the software should be changed to "In Line" mode. QG How to maintain the press unit? AG At ordinary times, the press unit needs attention to keep it clean, and filter's water should be drained. Besides, don't put other things in the cylinder. QG Does the sensor of the press unit need to be adjusted frequently? AG It is no need to adjust the sensor unless the fixture size is varied often. QG How many types for TR-518 series ICT fixture? AG 1.Press Unit 2.Vacuum 3.In Line.

QG Can mode 2 save debug time when the resistor in parallel with capacitor (3mF above)? AG Yes. QG Can mode 1 solve the resistor's low value problem when resistor in parallel with diode? AG Yes. QG Can mode 3, 4, and 5 make the test value more accurate when resistor in parallel with inductor? AG Yes. QG When a capacitor in parallel with another one and capacitance value is 10 times different, can the missing of the small capacitor cannot be tested? AG Yes. QG Is big capacitor (3mF above) tested by direct current and mode 4? AG Yes.

QG How to determine the press down depth of press unit in order to make UUT contact well? AG Usually 2/3 of the maximum stroke of probe is the best. Fewer will cause bad contact and more will damage the tip of probe. QG What situation will cause bad contact between UUT and fixture probe? AG 1.he press bars are not distributed evenly. 2.The press down depth is not enough. QG How to testify if the fixture pin is exactly contacted to the UUT test pin? AG 1.Use film pin diagram to compare fixture pin and UUT test pin.2.Cover a UUT bare board with blue transparent tape and put it on the fixture. Let the press unit down to stab through the tape and contact to the test pin, and then the contact can be testified. QG What is the advantage of DUT loader board of fixture? AG 1.To protect fixture pin.2.To load or unload UUT conveniently. QG When should the Japanese pin be used? What is the difference of the fixture height? AG For the long component pin such as Power Board, Mother BoardK that need longer pin stroke should use Japanese pin. The fixture height is 7.5cm.
