These days, not many cad software exist, Test Expert seems to be the only one that majority companies use. One of my friends asked me how to use the Test Expert to generate board and board_xy and DFT. I created this video to show the basic of Test expert. It has a lot of bugs, […]
Sometimes we do have to replace probes for any reason, especially smaller x-probes. The best way for not to miss or make mistake is to do it systematically. This is how I did mine. I had to replace 94 x-probes (No sockets). We should have a Mylar with color marked probes locations. Pull all the […]
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 […]
Beside changing tolerances using unix, sometimes I edit many files using F8 and re-save\compile file for quick modification sometimes.
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 […]
I’m sure there are many ways to detect LEDS at ICT. Many would use these color sensor inside the fixture. The only draw back for this type is the reliability and the costs of sensors themselves, also the fixture must be totally seal dark for the light sensors to work properly. I’ve never used any […]
I never like Test Expert, but since there are not many cad software out there and my company’s bought it already, I have to use it. The set up is also not very user friendly. Anyhow, I document this in case I get a new computer (mine is only 8 year old) with Windows 7 […]
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 […]
