VTEP/TestJet Testing

VTEP/TestJet Testing

Before beginning test development, determine if a VTEP1 test is appropriate for each device (see Table 6). Consider the following:

  • There must be metallic surfaces (pins, leads, or leadframes in the device) to which the VTEP probe can couple.
  • iVTEP enhances VTEP’s ablility to make reliable measurements where metallic surfaces (pins, leads, or leadframes in the device) to which the VTEP probe can couple are minimized. You should consider adding a VTEP test for all ICs.
  • Signal, sense, and digital probes for through-hole devices need to be placed at locations other than on the device; otherwise, you can test only for bent pins that are not inserted in the PC board.
  • Due to physical characteristics, some devices might require special fixturing.
  • Standard and small VTEP probes can be used on either side of the fixture, top or bottom; VTEP connector probes can be used only on the top side.

Also consider the VTEP/TestJet fixturing requirements.

To use VTEP to test devices on the board, there are four approaches to consider. They are:

  • VTEP Test Only — Test appropriate devices with VTEP to verify only the presence and connectivity of the device.
  • VTEP Test with Disable Information — Test devices with VTEP and include setup-only library tests with disable information for devices that need to be disabled for powered tests of downstream devices.
  • VTEP Test and Powered Test — Test devices with VTEP and include library tests for powered testing. To release the test and fixture to production as soon as possible you can test devices with VTEP only, but include setup-only tests and add powered testing later.

 

If you plan to add VTEP probes to your fixture in the future, specify them as you develop the board test so that space and resources are provided in the fixture. Adding VTEP probes later without the necessary space and resources may be very difficult or even impossible.

  • VTEP Test and NPM Test — Test connectors with additional coverage for power, ground and fixed pin coverage. You do this by specifying a connector model from Table 5.
  • To request for a library file for a new connector not currently in your ICT software, go to www.agilent.com/see/npm and click the link under New NPM Connector Library File Request.

Perhitungan & Cara Merubah Kumparan Blender Dari 220 V Menjadi 12 V

          Seperti yang telah dijelaskan pada buku “menggulung motor listrik arus bolak-balik, servis peralatan listrik rumah tangga kelompok penggerak dan perbaikan peralatan listrik pertukangan”, bahwa motor penggerak yang digunakan pada perlatan listrik rumah tangga dan pertukangan seperti blender, mixer, bor tembak, gerinda dsb menggunakan jenis motor universal. Motor universal adalah jenis motor listrik yang dapat disuplai dengan sumber listrik arus bolak-balik (AC) dan arus searah (DC). Jadi peralatan-peralatan listrik rumah tangga dan pertukangan tersebut yang biasanya kita suplai dengan sumber listrik AC dari PLN atau Genset sebesar 220 V sebenarnya dapat juga kita suplai dengan sumber listrik DC yang tentunya tegangan juga harus sama yakni 220 V.           Yang menjadi permasalahan bagaimana kalau peralatan listrik rumah tangga atau pertukangan tersebut, sebagai contoh misalkan blender yang ingin digunakan atau dioper...

BT-BASIC command line

8.8       At the BT-BASIC command line type the command  msi  and the directory path, then press the “ENTER” key on the keyboard.  Example:                   msi ‘/hp3070/boards/aspect/main’ 8.9       At the BT-BASIC command line type the command  get ‘testplan’ and press the   ENTER” key on the keyboard.  You should now see the body of the testplan file displayed in the work space of the BT-BASIC window. 8.10     Some of the most frequently used BT-BASIC commands used are:

Testhead

4.3         Testhead The testhead is that portion of the tester that supports the PIN, ASRU and Controller cards.   The testhead is divided into two BANKS and each BANK is divided into two MODULES, see figure 2 below.  Bank 1 contains modules 0 and 1, bank 2 contains modules 2 and 3.  The test fixtures are placed on the banks of the tester and locked down for board testing.  The testhead cards interface to the test fixture through the spring loaded pogo pin “nails” at the top edge on each of these card types. 4.4       Support Bay The support bay is a stand-alone cabinet that houses the power supplies for the Unit Under Test.  This bay also houses the test station power distribution unit and test station controller on earlier models. 4.5       Emergency Shutdown Switch The emergency shutdown switch is the large red button located at the lower left corne...

Kelebihan dan Kekurangan Saluran Listrik Jenis Saluran Udara dan Saluran Bawah Tanah

Berdasarkan pemasangannya,   saluran distribusi dibagi menjadi dua kategori, yaitu : saluran udara (overhead line) merupakan sistem penyaluran tenaga listrik melalui kawat penghantar yang ditompang pada tiang listrik. Sedangkan saluran bawah tanah (underground cable) merupakan sistem penyaluran tenaga listrik melalui kabel-kabel yang ditanamkan di dalam tanah. 1.    Saluran Bawah Tanah (Underground Lines) Saluran distribusi yang menyalurkan energi listrik melalui kabel yang ditanam didalam tanah. Kategori saluran distribusi seperti ini adalah yang favorite untuk pemasangan di dalam kota, karena berada didalam tanah, maka tidak mengganggu keindahan kota dan juga tidak mudah terjadi gangguan akibat kondisi cuaca atau kondisi alam. Namun juga memilik kekurangan, yaitu mahalnya biaya investasi dan sulitnya menentukan titik gangguan dan perbaikannya. Kedua cara penyaluran memiliki keuntungan dan kerugian masing-masing. Keuntungan yang dapat diperoleh dari suatu jaringan bawah...
