What Is a Multilayer PCB? A multilayer PCB is a printed circuit board composed of multiple copper layers separated by prepreg and core materials. Unlike single-sided or double-sided PCBs, multilayer boards provide additional routing layers, allowing engineers to design high-density circuits with improved electrical performance. Typical multilayer PCB configurations include: 4-layer PCB 6-layer PCB 8-layer...
What Is a Fine Pitch PCB? A Fine Pitch PCB is a printed circuit board designed to support fine-pitch components, such as fine-pitch BGA, QFN, CSP, and high pin count ICs, where the spacing between pads and traces is extremely small. Fine pitch PCB technology is essential for modern electronics that demand high density, compact...
What Is a High Density PCB? A High Density PCB (High Density Printed Circuit Board) is designed to accommodate more components, higher pin counts, and finer routing within a limited board area. It is widely used in applications that require compact size, high performance, and complex signal routing, such as semiconductor testing, telecommunications, automotive electronics,...
What Is a High Pin Count IC Test Board? A High Pin Count IC Test Board is a specialized printed circuit board designed to support integrated circuits with a large number of I/O pins during semiconductor testing. It serves as the electrical interface between the device under test (DUT) and automated test equipment (ATE), enabling...
A High Pin Count PCB is designed to support electronic components with a large number of I/O pins, such as high-density BGAs, processors, FPGAs, and ASICs. As modern electronic systems demand higher performance, faster data transfer, and increased functionality, high pin count devices have become increasingly common. Manufacturing a reliable high pin count PCB requires...
What Is a High Layer Count PCB? A High Layer Count PCB refers to a multilayer printed circuit board containing a large number of copper layers, typically 12 layers and above, designed to support highly complex circuit routing and high-speed signal transmission. High Layer Count PCBs are widely used in advanced electronic systems that require...
What Is a Blind Via PCB? A Blind Via PCB is a multilayer PCB that contains vias connecting an outer layer to one or more inner layers without going through the entire board. Unlike through-hole vias, blind vias enable high-density routing and space-saving designs, which are critical for HDI PCBs, high-frequency applications, and compact electronics....
Automated Test Equipment (ATE) PCBs are critical components in high-precision testing systems for semiconductors, modules, and electronic assemblies. Unlike standard PCBs, ATE PCBs must support high-density routing, controlled impedance, fine-pitch interconnects, and reliable signal integrity, ensuring accurate and repeatable test results. Why ATE PCBs Require Specialized Materials ATE systems often operate under high-speed digital or...
A BT Epoxy PCB is a specialized organic substrate widely used in IC packaging, semiconductor interposers, and high-density electronic modules. BT (Bismaleimide Triazine) epoxy resin materials are engineered to provide enhanced thermal stability, low moisture absorption, and excellent dimensional control, making BT Epoxy PCBs a preferred choice for fine-pitch and high-I/O-count packaging environments. Unlike standard...
What Is a Fine Line PCB? A Fine Line PCB is a high-precision printed circuit board manufactured with ultra-thin trace width and tight trace spacing, enabling high-density routing for advanced electronic products. Compared with standard PCB technology, Fine Line PCB fabrication focuses on achieving smaller line/space (L/S), higher wiring density, and improved signal performance in...
