How to Address IoT Eco-security in the Era of Digital Transformation?22 April 2022
This document was written by PSA Certified and Microsoft to illustrate the common goals of PSA Certified's 10 Security Goals and Microsoft's Seven Attributes of High-Security Appliances.
Optical Transceiver Guide: How It Works, Types, Form Factors, and Selection24 June 2026
An optical transceiver is the replaceable interface between electronic network equipment and an optical fiber link. It converts electrical data from a switch, router, server, storage system, or transport platform into modulated light, then converts received light back into electrical data.
IATF 16949 for Automotive Electronics: Quality Requirements, Standards Alignment, and Certification Guide04 September 2026
This technical guide details IATF 16949 quality management requirements for automotive electronics, semiconductor, and PCBA manufacturing. It explains how to synchronize the standard with AEC-Q qualification, ISO 26262 functional safety, and Automotive SPICE frameworks. Covering the 5 Core Tools, shop-floor environmental controls, IATF Rules 6th Edition updates, and certification pathways, it provides quality teams with a practical roadmap to achieve zero-defect compliance.
Electrical Symbols & Electronic Symbols: A Practical Guide to Reading Circuit Diagrams17 June 2026
Electrical symbols and electronic symbols are simplified graphical marks used in circuit diagrams, wiring diagrams, schematics, and technical drawings. They represent components, connections, power sources, protection devices, measurement points, and signal functions without drawing the physical shape of every part.
Decoding AEC-Q100: A Sourcing Guide to Automotive Grade Semiconductor Qualification and Temperature Ratings11 August 2026
Sourcing automotive grade semiconductors requires understanding AEC-Q100 qualification standards beyond mere marketing claims. This guide covers how ICs earn reliability through rigorous stress testing across specific temperature grades (0 to 3). Learn why compliance relies on supplier-provided Production Part Approval Process (PPAP) documentation rather than central certificates, how to verify part suffixes, and why substituting industrial components introduces catastrophic risk.
MLCC DC Bias Derating: How to Calculate and Compare Effective Capacitance Before Component Selection11 September 2026
Class II ceramic capacitors suffer significant capacitance loss under DC voltage due to ferroelectric domain saturation and high electric field intensity. This comprehensive engineering guide explains how to calculate true worst-case effective capacitance by compounding DC bias, temperature, tolerance, and aging. It provides multi-vendor simulation workflows, benchtop impedance measurement techniques, and practical guidelines to maintain power supply stability and avoid costly design failures.
Sourcing Silicon Capacitors and MLCCs in the AI Hardware Era13 August 2026
Modern AI hardware requires a hybrid Power Delivery Network (PDN) to maintain low-voltage stability under extreme transient currents. Deep Trench Silicon Capacitors (DTCs) integrate directly into advanced packages to deliver ultra-low ESL and stable performance for high-frequency transient suppression. Meanwhile, Multilayer Ceramic Capacitors (MLCCs) provide essential bulk energy storage on the motherboard, making both technologies complementary across the AI power stack.
High-Capacity HDDs in the AI Era: Sourcing Massive Storage for Cold Data04 July 2026
As generative AI and LLMs drive an explosion of unstructured data, high-capacity enterprise HDDs remain the most cost-effective solution for cold storage. Despite rising prices and supply chain bottlenecks, mechanical drives offer a massive cost-per-gigabyte advantage over SSDs. Technologies like HAMR and SMR enable capacities beyond 24TB, though deploying these drives requires robust RAID 6 strategies and secured IC supply chains to mitigate rebuilding and procurement risks.
The Proactive Playbook for EOL Component Sourcing: Managing NRND Without Adding Risk09 June 2026
Managing component obsolescence (EOL/NRND) requires a proactive strategy that aligns procurement and engineering. Rather than reactively buying risky surplus stock, hardware teams should build obsolescence risk registers, use structured decision matrices, and pre-qualify Form-Fit-Function alternates using modern CAD tools. When redesigns are impossible, executing precise Last Time Buys stored under JEDEC and NASA nitrogen standards preserves supply chain continuity.
Pull-Down Circuit Guide: Working Principle, Resistor Value, Circuit Design, and Applications26 June 2026
Learn how pull-down circuits work, how to choose a pull-down resistor value, and how to design reliable microcontroller inputs, MOSFET gates, reset pins, and sensor interfaces.
Decoupling Capacitor Placement Guide: Maximizing Power Integrity in High-Speed Digital PCBs12 August 2026
This technical guide details how to optimize decoupling capacitor layout to maximize Power Integrity (PI) in high-speed digital PCBs. It explains how switching ICs induce power rail noise, the physics of parasitic loop inductance, and the impact of stackup plane separation. Layout engineers will find practical strategies for via placement, anti-resonance mitigation across multi-value capacitor networks, and sourcing reliable low-ESR MLCCs.
Magnetic Sensors for Position Detection: Hall Effect vs. AMR vs. TMR Engineering Guide21 August 2026
This guide compares Hall effect, AMR, and TMR magnetic sensors for position detection in motor control and robotics. It explains their physical principles, key performance metrics, and selection criteria. Hall effect suits low-cost commutation, AMR offers high-speed angle sensing, and TMR provides maximum precision and low power, with practical integration advice.
