Preface

The PT-55 SMD Peel Force Tester is built with the following features:
• Optional Windows 7/XP laptop with security bracket and software for controls
• Automated home and calibration positioning
• USB communications interface
• Easy design allows operator calibration in minutes
• Standard EIA peel speed (microprocessor controlled)
• Handles all tape widths from 8mm to 120mm and 35.5mm pocket depth
• Measures in grams or newtons
• Customizable data fields
• A sampling rate of 550 times a second
The intended use of the PT-55 SMD Peel Force Tester is to measure the peel force of sealed
SMD tape. Use of this equipment in any other way is not recommended.
This Operator's Manual describes how to setup and operate the PT-55 SMD Peel Force Tester. It
should be read and thoroughly understood before operating the machine.

Theory of Operation

Operation of the PT-55 is simple. The operator enters customer/tape data and peel force settings
into the PT-55 software. A sealed tape sample with a small portion of cover tape peeled back is
loaded into the adjustable carriage track between the idler wheel and the sprocket wheel. The
tape must be positioned so the sprocket holes of the tape placed over the pins of the sprocket
wheel.
The operator attaches an alligator clip from the load cell chain to the edge of the loose cover
tape. The test is begun by pressing the Start button on the HMI.
During the test, results are displayed on the computer HMI. Upon completion a PASS or FAIL
message will appear on HMI. The completed pull test may be saved or printed or reset to run a
second sample.
