1. Overview of the Hitachi CMI500 System<\/h2>\n

The Hitachi CMI500<\/b> is a multi-functional coating thickness gauge system. Its primary strength lies in its modularity; the base unit can be equipped with different probes depending on the measurement task. Whether you are using the CMI500 ETP Probe for through-holes or the SRP-4 Probe for surface copper, the system provides a unified interface for data collection and analysis.<\/p>\n

2. Core Functionality and Modular Probe Technology<\/h2>\n

The CMI500 is famous for its “Plug-and-Play” probe architecture. By switching probes, the device toggles between different physical principles, such as Micro-Resistance and Eddy Current.<\/p>\n

The ETP (Electromagnetic Through-hole) Probe<\/h3>\n

For measuring copper thickness inside a hole, the ETP probe<\/a> for CMI500 is the industry standard. It uses eddy current technology to measure the barrel of the hole without being influenced by the surface copper. This is critical for determining if the PCB hole copper is thick enough to handle the electrical load.<\/p>\n

The SRP-4 (Surface Resistivity) Probe<\/h3>\n

When the task shifts to Surface Copper Thickness<\/b>, the system utilizes the SRP-4 measurement probe<\/a>. This probe uses a Four-Point Probe micro-resistance method, ensuring that the thickness reading is substrate-independent. It doesn’t matter if there is copper on the other side of the board; the SRP-4 only measures what is directly beneath the pins.<\/p>\n

3. Industrial Applications in Electronics Manufacturing<\/h2>\n

The CMI500 serves as a critical thickness tool<\/b> across various stages of the fabrication process.<\/p>\n

Plating Through-Hole (PTH) Inspection<\/h3>\n

The most common application is Plating Thickness Testing in through-holes<\/a>. If the copper in the hole is too thin, it can lead to “knee cracks” or open circuits during soldering. The CMI500 provides the High Precision Thickness data needed to approve or reject a batch before it moves to final assembly.<\/p>\n

Surface Finishing and Solder Measurement<\/h3>\n

Beyond copper, the CMI500 can be used for Solder Thickness Measurement and checking other surface finishes. In the Surface Finishing<\/a> Industry, ensuring that the unit of thickness for gold or tin plating is correct is essential for both cost control and functional reliability.<\/p>\n

Multi-Layer Board Analysis<\/h3>\n

For Multi-Layer Coating<\/b> boards, the CMI500 can measure the thickness of individual layers during the build-up process. This ensures that the core thickness and the overall standard pcb thickness remain within the design window of 1.6mm or other custom specifications.<\/p>\n

Plated thru-hole copper thickness with temperature compensation<\/p>\n

RAPIDLY MEASURE PLATED THRU-HOLE COPPER THICKNESS PRIOR TO, AND AFTER ETCHING<\/p>\n

The CMI511 has an exclusive temperature compensation feature for in-process thickness measurement to reduce scrap and costly rework. Its automatic temperature correction makes it highly accurate even for measurement on boards that have just been lifted from the plating tank.<\/p>\n

This gauge is an ideal choice for:
\nPCB manufacturing and assembly.
\nThru-hole copper thickness.<\/p>\n

The CMI511 does not require additional standards because it is factory calibrated ensuring its performance is always highly accurate. It is ideal for double-sided and multilayer boards, even plated with tin and tin\/lead. The CMI511\u00ae provides instantaneous measurements, and is so easy to use that no operator training is necessary.<\/p>\n

Our CMI511 comes complete with a carry case that features a plastic window which allows use of the gauge even without removal from the case<\/p>\n

FAQ<\/h2>\n

1. Can the CMI500 measure blind vias or microvias?<\/strong><\/p>\n

Do not assume that a through-hole probe can measure blind vias or microvias. Limited access and different geometries may make the method unsuitable. Ask the supplier to evaluate representative samples before specifying the gauge for these applications.<\/p>\n

2. How does the CMI500 measure through-hole copper thickness?<\/strong><\/p>\n

It uses the eddy-current principle. The instrument evaluates the probe\u2019s electromagnetic response and applies the sample settings to calculate hole-wall copper thickness. It is not a four-point surface microresistance measurement.<\/p>\n

3. Which probe does the CMI500 use?<\/strong><\/p>\n

The CMI500 uses an ETP probe for through-hole copper measurements. Hitachi lists ETP part number 10003192 for the CMI500 and CMI700 series. Confirm compatibility with your instrument before purchasing a replacement.<\/p>\n

4. Can the CMI500 measure surface copper thickness?<\/strong><\/p>\n

The CMI500 through-hole system should not be selected for surface copper measurements. Its ETP probe is designed for hole-wall copper. If you need to inspect copper foil, laminates, or traces, specify a suitable surface-measurement gauge separately.<\/p>\n

5. What is the measurement range of the CMI500?<\/strong><\/p>\n

The range depends on the exact model and probe configuration. Request the specification sheet matching the instrument\u2019s model number and serial number. Do not automatically apply CMI511, CMI700,<\/a> or CMI760 specifications to a unit described only as \u201cCMI500.\u201d<\/p>\n

6. What is the minimum hole diameter the CMI500 can measure?<\/strong><\/p>\n

The minimum measurable hole diameter depends on the probe and sample geometry. Provide the finished hole diameter and board thickness when checking suitability. The probe must enter freely; forcing it into an undersized hole can damage the tip.<\/p>\n
