PCB Technology

A microvia PCB uses laser-drilled vias with a 1:1 aspect ratio to interconnect adjacent HDI layers. Here is how microvias are formed, filled, and made reliable.

HDI PCB manufacturing builds boards through repeated laser drilling, plating and sequential lamination cycles. See the full process and its quality limits.

An HDI PCB packs more interconnect into less board area using laser-drilled microvias, blind and buried vias, and sequential lamination. Here is how it works.

1 layer PCB, also known as single‑sided PCB, represents the most basic form of printed circuit board. Conductive copper foil exists only on one side of the dielectric substrate, and

FR-4 glass-fiber reinforced epoxy laminate is the most widely used base material for printed circuit boards (PCBs). Its material properties have a significant influence on the reliability, electrical insulation, mechanical

What is copper clad laminate? Copper Clad Laminate, abbreviated as CCL, serves as the core fundamental substrate for Printed Circuit Board (PCB) fabrication. It directly governs circuit boards’ insulation performance,

What is FR 4? FR 4 is the common abbreviation for glass fiber-reinforced epoxy resin materials widely adopted in the printed circuit board (PCB) industry. Strictly speaking, FR 4 is

A motherboard is a highly complex and integrated printed circuit board (PCB), which specifically refers to the mainboard installed inside core devices such as personal computers (desktops and laptops), servers

FR4 ranks as the most widely adopted copper clad laminate substrate in the field of printed circuit board manufacturing. Many practitioners simply define it as glass fiber reinforced epoxy sheet,

Solar panel PCB board serves as core photoelectric conversion components within the new energy sector. These devices directly convert light energy into electric energy by leveraging the photoelectric properties of

SMT refers to a complete set of standardized production workflows that rely on Printed Circuit Boards (PCBs) as substrates to automate component mounting, soldering and integrated assembly of electronic parts.Circuit

Flexible RF coaxial cables are pliable transmission lines engineered exclusively for high-frequency signal conveyance, featuring fully compliant internal and external structural materials. Their outermost layer consists of a highly elastic

RF coaxial cables are core components for high-frequency signal transmission in wireless communications, microwave testing, radar, aerospace, and related fields. The mainstream market offers three categories: flexible, semi-flexible, and semi-rigid.

What is a glass substrate? A glass substrate is a circuit board that uses glass as its core substrate material. It has replaced the FR-4 epoxy glass fibre boards long

Any layer HDI is an abbreviation for ‘Any layer High Density Interconnect’ and represents one of the most advanced forms of HDI PCB technology, embodying the most cutting-edge interconnect architecture

As optical modules are employed for high-speed data transmission and optoelectronic conversion, the manufacturing quality of their PCBs directly impacts the performance, stability, and reliability of the optical modules. Key

High Tg FR4 is a flame-retardant glass fibre reinforced epoxy resin substrate with a glass transition temperature (Tg) ≥170°C. It serves as a commonly used high-temperature resistant base material for

Rogers materials usually refer to a series of high-performance copper-clad laminates (CCLs) produced by Rogers Corporation, mainly including Rogers RO4000 series, RO3000 series, RT/duroid series, etc. This type of material

Electroless nickel immersion gold (ENIG) and electroplated nickel-gold plating represent the two predominant surface treatment solutions for LTCC ceramic substrates. Whilst both employ a core principle of ‘nickel underlay with

LTCC, which stands for Low Temperature Co-fired Ceramic, is, as the name suggests, a technology that co-fires multilayer ceramic materials with metallic conductors at relatively low temperatures (typically below 900°C).

As a core component within microelectronic packaging and interconnect technology, the evolution of co-fired ceramic technology profoundly reflects the escalating demands for performance, integration, and reliability within electronic systems. From

The main advantages of FR4 substrates are practical rather than universal: broad supply availability, mature fabrication processes, electrical insulation, and mechanical reinforcement for many rigid PCB designs. Those strengths can

FR4 substrate refers to printed circuit board substrates manufactured using FR4 material. FR4 is a glass fibre reinforced epoxy resin laminate offering excellent mechanical strength and electrical properties. Composed of

What is FR4? It is a designation used for a family of flame-retardant glass-fibre-reinforced epoxy laminates commonly used to build rigid printed circuit boards (PCBs). The glass fabric reinforces the
