The basic working principle of quartz crystal oscillator

Quartz crystal oscillators utilize high-quality piezoelectric crystals, harnessing the piezoelectric effect to generate stable oscillations. The crystal's quality factor (Q) directly impacts frequency stability—a higher Q provides a more accurate and reliable clock signal. The vibration frequency characteristics are determined by three key factors: crystal thickness, crystal geometry, and cutting method.

Effect of thickness on frequency

The frequency of a quartz crystal is inversely proportional to the thickness of the crystal:

Thin wafers: Support higher oscillation frequencies, ideal for high-frequency applications.

Thick wafers: small vibration amplitude and excellent resistance to mechanical shock

Technological breakthrough : Overtone crystal technology enables a chip with a fundamental frequency of 20MHz to reach 100MHz through the fifth overtone, allowing medium and low fundamental frequency chips to meet high-frequency requirements of hundreds of megahertz.

In industrial automation, robotics, and precision instruments, connector performance is often the “invisible bottleneck” that limits system reliability. Traditional connectors can be hard to route in tight spaces, difficult to service, and prone to interference. WAIN’s MI Series miniature high‑density connectors give engineers a space‑saving, easily maintained, high‑reliability alternative.

Break the Space Barrier 

· MI connectors feature a compact form factor that is smaller than conventional products while integrating three functional modules—signal, power, and brake—into a single unit. This eliminates cable clutter and frees up valuable enclosure space, making the connectors easy to embed in robot joints, AGV control bays, or precision-instrument compartments.

· A partitioned, removable-module design allows users to detach either the signal or power section independently. If one module fails, the entire connector does not need to be replaced, dramatically reducing maintenance time and cost. Compared with traditional one-piece connectors, service efficiency is significantly improved.

Five Core Technology Innovations

1、One-Second Quick-Release — Latch Mechanism
MI connectors use an elastic latch-lock design that mates or unmated with a single press, cutting installation time. Anti-mis-mate coding ensures precise, reliable connections.

2、Vibration-Resistant Cold-Crimp Contacts
Contacts are cold-crimped—no soldering—delivering high-strength conductivity. Tested to withstand 500+ mating cycles, ideal for high-vibration environments such as industrial robots and rail systems.

3、360° Electromagnetic Shielding + Partitioned Isolation
Dual-layer protection:
• Outer full-metal shell blocks external EMI.
• Inner isolation chambers physically separate power and signal sections, eliminating crosstalk and guaranteeing zero-packet-loss data transmission.

4、Dual-Cable Exits for Flexible Routing
Independent power and signal channels exit through Ø 7.5 mm ports, accommodating large-gauge power and fine-gauge signal wires. The plug supports 180° dual-direction swivel, adapting to varied equipment layouts.

5、Visual Assembly — Top + Side Inspection Windows
Technicians can verify pin alignment in real time, preventing bent pins from blind mating. During service, windows enable rapid fault location, lowering technical complexity and downtime.

The open-source RISC-V instruction set architecture has rapidly evolved from a niche academic project into a global force reshaping the processor market. Over the past few years, semiconductor companies, research institutions, and startups alike have embraced RISC-V for its flexibility, reduced licensing costs, and potential for highly customized chip designs. Its adoption is accelerating in sectors ranging from data centers to low-power embedded systems, driven by the need for scalable performance and open innovation.

One of the fastest-growing areas for RISC-V implementation is AIoT (Artificial Intelligence of Things). As smart devices integrate AI capabilities at the edge, processors must handle both machine learning inference and complex sensor data processing locally. This trend is mirrored in embedded control systems, industrial automation, and edge computing platforms—where low-latency decision-making is essential. The modular nature of RISC-V allows chip designers to fine-tune cores for specific workloads, from high-performance neural processing to ultra-low-power microcontrollers.

Yet, no matter how sophisticated the processor architecture becomes, its performance is inherently tied to the accuracy and stability of its clock source. This is where crystal oscillators play an irreplaceable role. A crystal oscillator generates a precise and stable frequency signal, ensuring that instruction execution, peripheral communication, and data synchronization occur with consistent timing. Without such stability, high-speed data buses, wireless communication modules, and real-time control loops would be prone to errors and latency spikes.

In AIoT devices, for example, a small deviation in the processor clock can lead to cumulative timing mismatches between sensor inputs and AI algorithms, affecting recognition accuracy. In embedded systems such as automotive controllers or medical devices, clock instability could disrupt safety-critical operations. Even in edge computing nodes handling distributed workloads, accurate timing signals are crucial for coordinating processes across multiple devices in a network.

RISC-V processors, particularly those targeting wireless connectivity standards like Wi-Fi, Bluetooth, and 5G, rely heavily on low-jitter crystal oscillators to meet stringent communication protocol requirements. The frequency precision determines not only the processor’s internal timing but also the synchronization of RF transceivers, ADC/DAC converters, and external memory interfaces. For industrial and defense-grade applications, temperature-compensated crystal oscillators (TCXO) or oven-controlled crystal oscillators (OCXO) are often paired with RISC-V chips to maintain stability in extreme environments.

The future of RISC-V will likely see even more integration with diverse hardware ecosystems—heterogeneous computing modules, AI accelerators, and advanced security enclaves. Regardless of these innovations, every design still begins with the same foundational requirement: a reliable, accurate, and stable clock source. The crystal oscillator remains the silent but indispensable enabler, ensuring that RISC-V’s open-source vision is matched by uncompromising operational precision.

In essence, the global rise of RISC-V is not just a story of architectural freedom and innovation; it is also a reminder that at the heart of every advanced processor lies a humble yet essential timing device—without which the promise of the architecture could not be fully realized.

In enterprise applications, charging and power supply stability determine system availability and productivity.

For researchers and engineers, understanding the core specifications of a Scanning Electron Microscope (SEM) is essential for obtaining accurate results. Among the most important parameters are SEM resolution, SEM magnification, and SEM imaging modes. These three factors define the level of detail, scale, and type of information that can be captured from a specimen. Knowing how they work and how they interact helps you select the right SEM for your application.

What is SEM Resolution and Why It Matters

SEM resolution describes the smallest distance between two points that can still be distinguished as separate. It is typically measured in nanometers. Higher SEM resolution means you can capture finer details, which is critical in nanotechnology research, semiconductor inspection, and advanced materials analysis.

The main factors affecting SEM resolution include electron beam spot size, accelerating voltage, electron source type, and vacuum conditions. For example, a field emission SEM generally achieves higher resolution than a thermionic SEM. Low accelerating voltage improves surface detail for delicate samples, while low vacuum operation enables better imaging of non-conductive materials.

Understanding SEM Magnification

SEM magnification is the ratio between the displayed image size and the actual area scanned on the sample. Unlike optical magnification, SEM magnification is controlled electronically by adjusting the scan area. Most modern SEMs offer magnification from about 10x to several hundred thousand times, making it possible to study both large structures and nanoscale features in the same instrument.

The Link Between SEM Resolution and SEM Magnification

While increasing SEM magnification enlarges an image, the level of meaningful detail still depends on the SEM resolution. If the resolution limit is reached, higher magnification will not reveal additional structural details. For example, a system with 1 nm resolution provides much clearer images at high magnification than one limited to 5 nm.

Common SEM Imaging Modes and Their Uses

Modern SEMs feature multiple imaging modes, each designed to provide specific information:

• Secondary Electron Imaging (SEI) – Delivers high-resolution surface topography, ideal for morphology studies.

• Backscattered Electron Imaging (BSE) – Reveals compositional contrast based on atomic number differences.

• Energy Dispersive X-ray Spectroscopy (EDS) – Identifies and quantifies elemental composition.

• Low Vacuum or Variable Pressure Mode – Allows imaging of non-conductive or hydrated specimens without metal coating.

Switching between different imaging modes enables comprehensive analysis of a single sample.

Choosing an SEM Based on Resolution, Magnification, and Imaging Modes

When selecting an SEM, consider the balance between SEM resolution, SEM magnification range, and available imaging modes. High-resolution capability is essential for nanometer-scale research. A wide magnification range ensures flexibility for different sample sizes, and multiple imaging modes increase versatility for both research and industrial applications.

How CIQTEK SEMs Excel in Resolution, Magnification, and Imaging Modes
