What is the difference between an average, range or minimum plating thickness specification and how do I properly call out my thickness requirement on a print? There are five (5) methods most commonly used for defining plating thicknesses. Proper coating thickness is crucial in both functional and decorative plating. Here are some common problems and ways to measure .
The non-destructive coating thickness measurements can be taken on either magnetic steel surfaces or non-magnetic metal surfaces such as stainless steel or aluminium. Digital coating thickness gauges are ideal to measure coating thickness on metallic substrates. Electromagnetic induction is used for non-magnetic coatings on ferrous substrates .

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 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 .
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 .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.
The sheet metal supplier applies the zinc coating either by galvanic deposition or in a zinc dip bath. If the zinc coating thickness is uniform, the thickness of the subsequently applied paint coating can be measured using a conventional magnetic induction coating thickness measurement instrument.
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% . 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.”
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. Consistent plating thickness is necessary to ensure proper performance during assembly.
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 .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.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 .
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".It is the economical choice that retains the uncompromising quality of DeFelsko coating thickness and inspection instruments. PosiTector 6000 — The rugged, fully electronic PosiTector 6000 Coating Thickness Gage uses magnetic and eddy current principles to measure coating thickness on both ferrous and non-ferrous metals, accurately and quickly.

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)The PosiTector 200 Ultrasonic Coating Thickness gage non-destructively measures a wide variety of applications using proven ultrasound technology. Measure paint and coating thickness over wood, concrete, plastic, and more. Advanced models measure up to 3 layers with graphics. Conforms to ASTM D6132 and ISO 2808. Proper specification of gold plating thickness for connector and contact applications is a key design consideration. Gold plating is an exceptional finish for connectors of that demand both high reliability and durability; however, the thickness of the gold plating will impact the durability and ultimate cycle life of the connector. Gold plated .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 .
Measurements of coating thickness are based on the fact that the time required for this process is proportional to the plating thickness. Can measure thicknesses of many types of plating, and can determine individual film thicknesses for multilayered plating. Cannot measure small items or sites with complex shapes.range of plating thickness on an item is a direct function of the standard deviation of the distribution. The goal is to strive for small standard deviations (leptokurtic . This assumes that the measurement location of deposit thickness is consistent from item to item. Significant Surface In addition to being normally distributed, the deposit .

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 .A reversible anvil lets you adapt the gauge to the shape of the object you are measuring. Use the round face on the anvil to measure the wall thickness of pipe, tubing, and other curved surfaces. Use the flat face to measure sheet metal, paper, and other flat stock.
