PosiTector 200 - Coating Thickness Measurement on Rough Surfaces. . A PosiTector 6000 probe is generally recommended over a PosiTector 200 probe for measuring coating thickness on metal substrates because – . Measurement of Conformal Coating on Printed Circuit Boards.
Conformal coating (CC) is widely used to protect printed circuit board from corrosion, mold growth, and electrical failures. To ensure effective protection, the thickness of the CC layer needs to be well controlled. However, to date, the coating thickness is usually measured in a destructive way under microscopes. In this paper, we proposed to use optical . Chase Global Operations Center and Corporate Headquarters . 375 University Avenue Westwood, MA 02090 Tel. 781.332.0700 Fax 781.332.0701
Current practice for measurement of the thickness of conformal coating typically involves measurement with a mechanical gauge with a least count of 25µm (0.001 inches) or 12.5µm (0.0005 inches). . There are many available techniques for measuring coating thickness, but most were found to have significant limitations that made them .
People then take averages to estimate the coating thickness. These are just two of the many avenues to take. The goal is to find at least one measurement technique that helps a company maintain tight PCB quality control. The correct PCB coating thickness matters. Failing to use enough conformal coating could result in the component not getting .Dry Conformal Coating Thickness Measurement An alternative method to wet film measurement is using an eddy current system like the Positector 6000. This system is extremely quick and accurate to ±1 um. Placing the test head on the surface of the conformal
Conformal Coating Thickness Measurement Methods The measurement of the conformal coating thickness on a printed circuit board (PCB) to ensure internal and international standards are met is now a critical factor in .

Conforms to ISO 2178/2360/2808, ISO 19840, ASTM B244/B499/D7091/E376, BS3900-C5, .AN001 Au/Pd coatings in the nm range on printed circuit boards 0.48 MB AN007 Thickness measurement of conformal coatings on printed circuit boards 0.99 MB AN034 Measuring the copper thickness in plated through-holes on PCBs 0.57 . Hardness measuring instrument for determining properties such as indentation hardness and the depth-dependent .
The galvanize coating is applied by the sheet metal supplier either by hot-dip galvanizing or by electrogalvanizing. If the zinc coating thickness were uniform, the thickness of the subsequently applied paint coating could be measured using a conventional magnetic induction coating thickness measurement instrument.Conformal coatings are usually applied as very thin coatings, providing the maximum protection possible using the thinnest amount of material. This minimizes heat entrapment, additional weight addition, and a variety of other concerns. Normal thickness with most conformal coatings is anywhere between 1 to 5 mils (25 to 127 microns) with some coatings applied at an even .

Typically, conformal coating is applied between 1 to 5 mils (25 to 127 microns). There are three main ways to measure the thickness of a conformal coating: Wet film thickness gauge-Wet film thickness can be measured directly by using gauges that have a series of notches and teeth - each tooth having a calibrated length. The gauge is placed .Fig. 1 a) Confocal measuring setup, b) interferometric coating thickness measuring principle (zoom) Fig. 2 a) Frequency modulation of the intensity signal. b) Corresponding thickness peak in the Fourier spectrum. a b . Conformal coating thickness inspec-tion in the production process The combination of the camera basedThe Positector 6000 N0 S1 is a precision instrument designed for the measurement of conformal coating thickness. With a coating range thickness of 0–25 mils (0–625 µm), it offers versatility across various coating applications.Fig.1: A 6000-NS1 measures on an acrylic coated printed circuit board with a solid copper ground plane . Solution #2 : For PCBs without copper ground planes. Our ultrasonic PT-200 B/Std gage measures conformal coating thickness on some printed circuit boards without a copper ground plane. Ultrasonic measurement has limited application on PCBs because the probe cannot be .
Ultrasonic Testing: Ultrasonic thickness gauges use sound waves to measure the thickness of the coating. The device emits ultrasonic pulses, and the time taken for the waves to bounce back from the substrate-coating interface is used to calculate the thickness. X-ray Fluorescence (XRF): XRF can be used to measure the thickness of conformal .An IBM circuit board from a NASA Space Shuttle computer with a conformal coating applied. Conformal coating is a protective, breathable coating of thin polymeric film applied to printed circuit boards (PCBs).
