Pressure Testing Kit

An Analytical Tool for Testing and Viewing the Amount and Distribution of Pressure Across a Printed Circuit Board

A PRESSPROBE Test provides a quick, simple and accurate in-house procedure for checking for "high" and "low" pressure zones due to (1) press platen misalignments or (2) the design configuration (pads, high density circuitry, ground planes, etc.) of the circuit board itself. Pressures, distributed unevenly, can lead to circuit board manufacturing problems and rejects.

Implementation of a PRESSPROBE Test will help the laminator view potential pressure-related laminating problems even before they occur.


Actual Pressprobe Test Results


  • A PRESSPROBE Test can be used routinely to check press platens for parallelism.
  • A PRESSPROBE Test provides an accurate way to pinpoint where and how pressure is distributed across the surface of the circuit board. The laminator can easily identify the presence of "high and low" pressure zones prior to actual lamination, which can impact scrap rates.
  • A PRESSPROBE Test can show uneven pressure distribution across the nip rollers of a Dry Film Laminator and can detect imperfections on the nip rollers themselves. PRESSPROBE testing can also highlight possible surface patterning on inner-layers (due to glass style) and therefor can characterize the possible affect that such irregularities may have in connection with the imaging of fine-lines.

A PRESSPROBE Pressure Testing Kit contains two separate rolls of testing film. These pressure-sensitive films react together to convert pressure into a measurable color hue or density and provide a graphic representation or "picture" of both the distribution and amount of pressure across the area being tested.
