Measuring plating thickness is an essential part of product development in dozens of industries. PlatingThickness.com – Your source for measuring instruments in plating industry +1 860 683-0781 Step 4: Measurement of Coating Thickness. Step 5: Correction for Base Metal Reading (if acquired). Each of these five steps will be described in this article. Some History. SSPC-PA 2, was originally published as a temporary standard over 40 years ago in 1973 (73T) as “Measurement of Dry Coating Thickness with Magnetic Gages.”SGS MSi can perform plating thickness testing using SEM and optical microscopy and testing to ASTM B748, B747, E3-11 and A90. Contact our lab to learn more. . ASTM A90, is the analytical method for measuring the amount of zinc coating applied to a steel product for a specified surface area. Zinc coatings protect steels against corrosion .
An additional, method that can be used to measure coating thickness is the Atomic Force Microscopy. It is included here as it shares similar principles as nanoindentation. AFM relies on a cantilever/ indenter to be brought to the surface of the material and dragged in a straight line across the surface. Any peaks or valleys are detected as the .
An electroless nickel coating is uniform; it will not build up on corners or projections. The deposited metal layer has an even thickness over all surfaces of the component regardless of its shape; this cannot be achieved with electrodeposited coatings. Typical thickness of electroless plating can be as thin as .0005" and up to.010".
The primary reason for measuring coating thickness destructively is to determine the thickness of the individual coating layers after multiple coats have already been applied. Nondestructive gages measure thickness cumulatively. That is, they cannot distinguish layers. While some ultrasonic gages can distinguish the thickness of individual .
atomic number of the coating layer, and the energy of the emitted lines used. In the past, XRF has been used to measure coat-ing thickness using stationary or benchtop instru-ments. However, the specimen must be brought inside or close to the analyzer chamber for analysis using stationary XRF methods, making measuring coating thickness on large .METAL PLATING PROCESSES AND METHODS OF MEASURING SURFACE HARDNESS AND THICKNESS OF COATINGS Technical Report TR-#105(Rev.Ø) 19650 Pauling Foothill Ranch, CA 92610-2610 . the purity, the substrate, the pre treatment, and the thickness of the coating. Electroless nickel solutions operate in a pH 4 - 9 medium at a temperature of . Precision Measurement: Plating thickness gauges offer high precision, ensuring that the thickness of the coating meets the exact requirements for the intended application. Non-Destructive Testing: These gauges typically employ non-destructive testing methods, which means they can measure the plating thickness without damaging the underlying .
Anodizing Coating Thickness Measurement Solutions The PosiTector 6000 "N" series of eddy current gages are ideal for non-destructive measurement of nonconductive coatings on non-ferrous substrates. The PosiTector 6000 NAS probe is specifically designed for high resolution measurement of anodizing on aluminum. Though capable of measuring up to 625 μm (25 . Overview of magnetic and eddy current measurement principles. When it comes to coating thickness measurement, two commonly used principles are magnetic induction and eddy current.Let’s take a closer look at each of these principles: 1️⃣ Magnetic Induction: Magnetic induction is a widely employed method for measuring coating thickness.It operates based .
The issues that determine what method is best for a given coating measurement include the type of coating, the substrate material, the thickness range of the coating, the size and shape of the part and the cost of the equipment. Commonly used measuring techniques for cured organic films include nondestructive dry film methods such as magnetic, eddy current, .One common method is to use a thickness gauge, which can be a handheld device used post-plating or an inline measurement system integrated into the plating line for real-time monitoring. Inline systems are particularly beneficial for continuous processes as they allow for real-time adjustments to ensure the consistency of the plating layer.Measuring Plating Thickness . Plating used on electrical component leads and as printed-wiring-board finishes is usually thin, less than 300 micro-inches, and it is important to verify that the plating thickness meets specifications. .DeFelsko paint thickness gauges for magnetic grades of steel. PosiTest — Magnetic pull-off thickness gage (banana gauge) for the non-destructive measurement of non-magnetic coatings (paint, enamel, galvanizing, .
Ultrasonic coating thickness gages (e.g. PosiTector 200) emit a high frequency sound pulse that travels into the coating via a coupling gel and reflects from ANY surface that is different in density.Paint thickness readings are obtained by measuring the time taken for the ultrasonic signal to propagate from the probe to the coating/substrate interface and back.
Example A: Imagine you take a measurement on a steel coil coated with zinc galvanize using a PosiTector 6000 F gage and obtain a single-side thickness reading of “0.35 mils.”This can be easily converted to oz/ft² using the following method: Multiply the gage reading of 0.35 mils by 2 to account for both sides of the panel (0.70 mils)

Selecting the appropriate plating thickness measuring instrument is crucial for industries where coating quality and adherence are paramount.Understanding Your Application: Before diving into the selection process, it's essential to have a clear understanding of your application. Different industries and scenarios may require specific features . What is Electroless Nickel Plating? Electroless Nickel Phosphorous (ENP) is a nickel-phosphorous alloy (NiP) deposited by a chemical process, unlike the galvanic process of nickel electroplating that requires an electric current. Phosphorous content (%P) ranges from 2%P to 14%P, and specific plating bath formulations produce deposits with low phosphorous (2% .XRF coating thickness measurement is a necessity for the billion metal finishing industry. It is also the technology tool that allows contract platers, whose margins are always under pressure, to deliver high quality coatings at lowest cost, knowing they are avoiding the risk of producing below spec, and the cost of wasting valuable material.

IPC-TM-650 Number 2.2.13.1 Subject Thickness,PlatinginHolesMicrohmMethod DateTable 1: Methods for measuring plating film thickness Description Features; Microscope cross-sectional observation methods: A cross section of the sample is sliced, embedded in resin, polished, and etched, and a vertical cross section of the plating is observed using a microscope to determine the coating thickness. The image may be recorded and .For most plating applications, the most common methods of measuring plating thickness are X-Ray Fluorescence (XRF), Optical Emission Spectroscopy (OES), and Eddy Current Testing (ECT). XRF is a highly accurate technique that can measure the thickness of a plated layer up to 10 mm thick. OES is less accurate than XRF, but is still a reliable .AN017 Automated coating thickness measurement in production facilities 0.73 MB AN030 Saving costs by using inline measurement for electroplating reel-to-reel applications 0.89 MB AN091 Different ways to achieve valid measurement values and optimize measurement performance 0.20 MB AN092 How to choose an XRF instrument 1.29 MB AN094 XRF analysis .
X-Ray Fluorescence Spectroscopy (XRF) allows for accurate quality control of printed circuit boards and electronics, by measuring plating thickness non-destructively. It can measure the plating thickness on large and fine-pitch conductors of a variety of plating finishes: tin-lead (Sn-Pb), immersion silver (ImAg), immersion tin (ImSn .
