PLT Operation Guide

Summary

The Production Line Tool (PLT) executes one or more test plans, for In-Circuit Test (ICT), Final Assembly, Test and Packout (FATP) or other production stations.

With a custom test suite definition, the PLT can also be used for integration testing during development.

It tests interactions over:

  • BLE
  • UART

During the Test plan, the PLT may also perform firmware programming of:

  • RF SoC
  • External flash

Setup

  • Connect the Ethernet port to a local network with (outbound) Internet access.
  • Connect the AC power socket to AC power (110-240VAC, 50-60Hz)
  • (Optional) Connect Zebra label printer to external USB port
  • (Optional) Connect Symbol bar code scanner to external USB port
  • Use power switch on rear of unit to power on the PLT.

Usage

DUT Connection

  • Use Tag-Connect TC2030-IDC cable to connect 6-pin rear-end IDC SWD socket with the DUT.
  • PLT-100A: Use Tag-Connect TC2070-IDC cable to connect 14-pin rear-end IDC Test socket with the DUT.
  • PLT-200A: Use Tag-Connect TC2050-IDC cable to connect 10-pin rear-end IDC JTAG socket with the DUT.
  • PLT-200A: Use HD78 cable to connect 78-pin rear-end ICT socket with the In-Circuit Test Fixture.
