Powerful administrative functions. Real time alert systems (option): Statistical systems: ICT console (option): Remote access test results data and their statistic charts to support manager analyze production problems, adjust the engineering process or trace back fail components to meet the key issue, original problem solving strategy. Edit and debug test program at remote side. Automatic generate useful production administrative charts, such as components test value distribution charts, daily charts, period charts, test pins fails ranking, failure component ranking and test coverage rate analysis…etc. PRG.

ICT360AT supports 7 kinds of charts: Statistical charts. Daily chart. Period chart. Distribution chart. IC measure value distribution chart. Rank for bad pins of the bed of nails. Rank for fail components. Coverage rate analysis chart.
Statistical charts Performance. Test program tuning as well as upper/lower limits setting for each test step. Tested board quality monitoring and production problems real time tracking. Components quality monitoring and problems trace back (ISO9001). Test pins quality monitoring and probe replace indication of the Bed of Nails.
Fixture convert for TAJ and HPJ. HPJ wiring.TAJ wiring MUX Card SWC Decoder Card
Convert TAJ to HPJ: CASE 1 HPJ TAJ (HPJ fixture wiring application on ICT360AT.) No such as Intel north bridge package IC, connector plug to SWC of ICT360AT directly. I.e. 100% HP pad compatible.
Convert TAJ to HPJ: CASE 2 HPJ TAJ (HPJ fixture wiring application on ICT360AT. Board pasted with IC package such as Intel North bridge. Drilling 3 rd hole for TA pad application and pull HP pad down then replace TAJ pad up. Then i. Pin+ / Pin- connect to Decoder Card of ICT360AT. ii.Connect 3 rd pin(Sync pin) connector to Switch Card of 360AT.
Convert HPJ to TAJ: CASE3 TAJ HPJ (TAJ fixture wiring application on HPJ fixture. Replace TAJ pad to HPJ pad. Connect TAJ pad Pin+ / Pin- fixture connector of ribbon cable to MUX Card connector. Leave 3rd Pin connector open circuit.
Test Programming Preparation The preparation for fixture making 1.CAD file or Gerber file of DUT 2.BOM of DUT 3.Bare board and assembled board (For high precision or multi-layer board, CAD file is recommend) Check list for fixture making 1.The probe for ECJ test should be Spherical type with long stroke and low spring force, the location of the probe should be precise. 2.The pitch of probe tube and the connection of the array-pin for TAJ test should be correct and can easily convert to HPJ test.

EC Jet On board electrolytic capacitor polarity and missing parts inspection. ECPD Technology ( E lectrolytic C apacitor P olarity D iscriminating T echnology.)
The challenges on production line. Traditional ICT test systems. 1.Very low Electrolytic Capacitor polarity discriminating rate(30%-50%). 2.Unable to find out the capacitor miss part during the test. Missing Parts. Wrong Orientation.
Challenge on production line. Inspecting by human eyes not only waste of time and money but also un- reliable as well.

Test limitations of EC Jet. Temperature. Parallel Capacitor Explosion free capacitor DUT with normal temperature between 0° ~ 55°C, failure rate = 0, 100% able to test. DUT with temp > 80°C, failure rate : about 20% DUT with temp >60°C, failure rate : less than 5% Huge value of capacitor affect the testing time (15-20ms /PCS), due to sampling time is a little longer. Explosion free capacitor needs long testing time. Due to the polarity characteristics of explosion free capacitor is not so clear as normal capacitor. Testing time as long as 200 ms/ pcs.
Benefits of EC Jet. Use old ICT: JET300 TR518. Use EC Jet. Instead of human Eyes Inspection. Getting higher quality. Use EC TestJet Save 2 ~ 3 Operators. Less Effort. Higher Quality.

Benefits of TA Jet Up to 100% BGA pins of solder joints Contacted/ Open inspection. Up to 100% Intel 845 BGA pins of solder joints Contacted/Open inspection. Up to 100% SCSI / PCI SMD connector solder joints Contacted/Open inspection. Make sure where the true BGA failures are.
Parallel pins. If circuit impedance small than 10ohms, the stimulus signal can not apply to almost a short circuit. Logically BGA parallel pins are same circuit, we can not discriminate if one of them is open circuit. Circuit impedance. BGA relative components. If the BGA relative component in O/S, missing part, wrong part fail, it may affect the test value of BGA. Limitations of BGA Open/contacted test.
