In the printed circuit board (PCB), semiconductor, and precision electronics manufacturing industries, controlling the thickness of plated layers such as Gold (Au), Nickel (Ni), Copper (Cu), or Palladium (Pd) plays a decisive role in product quality and durability. As components continue to shrink, conventional measurement methods no longer meet the strict accuracy requirements at extreme locations.

To solve the challenge of inspecting ultra-small measurement points and ultra-thin coatings, Maxlab proudly introduces a premium equipment line: X-ray PCB Coating Thickness Gauge iEDX-150µWT from the reputable brand Sense Instruments. This is a breakthrough technological solution that delivers outstanding measurement performance for today’s circuit board manufacturing and chip packaging plants.

The iEDX-150µWT coating thickness gauge is an enhanced tall version (加高版) featuring a specially designed sample chamber combined with today’s most advanced X-ray optical technology. Unlike conventional X-ray thickness gauges that use traditional collimators, this model utilizes a polycapillary optical system to focus the X-ray beam down to micrometer sizes.

The letters “WT” in the model name represent the slotted sample chamber design and the elevated stage. This allows the equipment to easily accommodate large PCB panels or components with complex geometric structures without being restricted by the measurement chamber space.

To become a leading device in the electronics industry, the iEDX-150µWT is equipped with a series of powerful technological innovations:

This is the most valuable feature of the iEDX-150µWT model. Thanks to the micro-capillary guide tube system, the emitted X-ray beam is focused to create an extremely small light spot (光斑) ranging from 15 µm to 50 µm.

In the PCB manufacturing industry, panel boards are often large. A standard sample chamber either cannot fit them or makes it difficult to move the stage. The iEDX-150µWT completely solves this problem thanks to:

The device integrates an advanced Silicon Drift Detector (SDD), providing an ultra-high pulse count rate and excellent energy resolution. This allows the machine to clearly separate the energy peaks of metals located close to each other in the periodic table, thereby accurately analyzing complex multi-layer coatings (e.g., Au/Pd/Ni/Cu) without confusion.

With its ability to measure ultra-small spots and analyze ultra-thin layers, the iEDX-150µWT X-ray PCB coating thickness gauge is an indispensable quality control link in many fields:

On high-density interconnect boards (HDI PCB) or flexible printed circuits (FPC), areas with electroless nickel immersion gold (ENIG), electrolytic gold, or nickel plating usually have very small footprints. The iEDX-150µWT precisely measures the thickness of ultra-thin gold layers (only a few nanometers) and the underlying nickel layer, ensuring the electrical conductivity and solderability of the circuit board.

Semiconductor lead frames require uniform plating to protect and connect the chip. The device supports rapid inspection of coating thickness at ultra-small transition zones on the Lead Frame, preventing coating peeling defects during the packaging process.

In the era of microprocessing chips, coatings on chip surfaces require atomic-level precision. The iEDX-150µWT perfectly meets these strict standards, helping engineers tightly control the electroplating process in cleanrooms.

The machine is also widely applied to inspect connectors, plugs, and MLCC (Multi-Layer Ceramic Capacitor) components – places with uneven surfaces where the target measurement points are deep within the hardware structure.

If your business is deciding between a conventional collimator-based X-ray machine and a polycapillary machine like the iEDX-150µWT, here are the compelling reasons:

Investing in the iEDX-150µWT model helps businesses reduce the rate of defective goods (NG), optimize the amount of precious metals used in plating (avoiding over-plating which wastes capital), and enhance competitive capacity when entering the global supply chains of major corporations.
