All About ICT HP3070
Many of our boards these days have TIC controller (MSP430F155IPM) to control power supply inputs – One of the requirement for our ICT is to program this TIC on board. We need a main board that has the CPU to check and program the TIC controller if it’s blank or wrong firmware version. It does …
If our test boards have some push button switches that need to be tested, we used to use manual hand push rods, it’s time consuming and the operators do make mistake when their fingers are tired from pushing them. Some fixture vendors offer pneumatic solenoid push rod which are very reliable and extremely quick to …
As an HP3070 engineer, I have to transfer files from/to between my PC and HP3070 quite often. I used both cuteftp and coreftp for these tasks. Here is how I set up these programs for my Windows PC, all you need is the ip address of your HP3070 and your username and password.[non-members]please log in …
Since I’m an OEM developer, I kept our system software rev at the lowest since HP3070 software is not backward compatible. Sometimes, when we need to re-do the software for a fixture, we get the program folder back, we have to convert everything down to our system rev level. Our system software is 3.6 compares …
Many times we have to add additional tests that requires adding wires in the fixture. My board has 3 pressed fit mounting washers need to be tested at ICT for presence. The fixture vendor put 3 switches there with wires ready to be wired to the fixture. I do have the mounting hole with the …
All shorts test fail on all boards and yesterday they’re fine. Before we debug our fixture, run diagnostic for the system and find out one of the hybrid cards we used for the fixture has bad relays. We swapped the hybrid card and it moved to the new slot. While waiting for the service people …
ICT test engineers in smaller OEM companies normally wear many hats, system maintenance is one of them. We may have the luxury of having a system in the company and it does fail once in a while although HP3070 is extremely reliable. When we run diagnostic for the whole system and we see failures on …
I had to program PIC28F8722 micro controller at ICT test station. I found a solution for less than $300. and some custom fixture designs. The main board design must have a 5 pins header which has ICT test points. MCLR, DATA, SCLK, GND, VCC. I found a PIC program to go on the internet for …
