What Is a Microvia PCB? A Microvia PCB is an advanced type of HDI (High Density Interconnect) printed circuit board that uses laser-drilled microvias, typically with a diameter of ≤150 μm, to interconnect PCB layers. Unlike traditional mechanical vias, microvias are designed for shorter signal paths, higher routing density, and compact layouts, making them essential...
What Is a High Reliability PCB? A High Reliability PCB is engineered to deliver stable electrical performance, mechanical durability, and long-term consistency under extreme operating conditions. Unlike standard commercial PCBs, high reliability PCBs are designed to withstand high temperature, thermal cycling, vibration, humidity, and continuous operation without performance degradation. These boards are widely used in...
A Multilayer PCB is a printed circuit board composed of three or more conductive copper layers laminated together with insulating materials. As electronic products continue to demand higher functionality, faster signal speeds, and smaller form factors, multilayer PCBs have become the backbone of advanced electronics, semiconductor testing, communication systems, and industrial control equipment. Compared with...
A Low Loss PCB is a specialized printed circuit board designed to minimize signal attenuation, dielectric loss, and insertion loss in high-speed digital and high-frequency RF applications. As modern electronics operate at multi-GHz frequencies and multi-gigabit data rates, signal loss caused by PCB materials and structures becomes a critical limiting factor. Low loss PCBs are...
A Fine Pitch PCB is a printed circuit board specifically designed to support high pin count ICs and ultra-small component spacing, commonly found in modern semiconductor devices, high-speed electronics, IoT modules, automotive electronics, and advanced test boards. As electronic products continue to shrink while integrating more functions, fine pitch PCB technology has become essential for...
A High Density PCB (HDPCB) is a specialized printed circuit board designed for compact, high-performance, and high-pin-count electronic applications. HD PCBs are widely used in semiconductor test boards, IoT devices, wearable electronics, automotive systems, and high-speed communication modules, where space constraints, signal integrity, and reliability are critical. High density PCBs combine fine-pitch component layouts, multilayer...
An IoT IC Test PCB is a specialized printed circuit board designed to validate low-power, high-density, and high-functionality IoT integrated circuits. These ICs combine analog, digital, RF, and sensor interfaces in compact packages, often operating at low voltages and requiring precise timing for wireless communication. IoT IC test PCBs are widely used in Automated Test...
An Automotive IC Test PCB is a specialized printed circuit board used to validate automotive-grade integrated circuits, including power management ICs, microcontrollers, ADAS sensors, RF modules, and in-vehicle communication ICs. Automotive ICs must meet stringent reliability standards due to harsh operating environments, temperature extremes, and safety-critical applications. These test PCBs play a critical role in...
A 5G IC Test PCB is a specialized printed circuit board used to validate 5G baseband ICs, RF transceivers, power amplifiers, and mmWave front-end modules. As 5G technology operates at sub-6 GHz and millimeter-wave frequencies, the performance requirements for test PCBs are significantly higher than those for conventional IC testing. 5G IC test PCBs play...
A High Speed IC Test PCB is a specialized printed circuit board designed to support high-frequency, high-data-rate, and fast edge-rate integrated circuit testing. As modern ICs operate at GHz-level frequencies and multi-gigabit data rates, traditional PCB designs are no longer sufficient to guarantee accurate test results. High speed IC test PCBs are widely used in...
