FR4 HDI PCB Printed circuit boards
High Density Interconnect
HDI PCBs are printed circuit boards with a much higher wiring and pad connection density than a traditional PCB. HDI PCBs are characterized by finer lines, closer spaces, smaller capture pads, and micro-sized vias. HDI PCB manufacturing is a growing area since the market demand for lightweight and thinner PCBs that can handle high-speed signals with reduced signal loss has steadily increased as consumer electronic end-products are produced in smaller form factors.
As a result of the market demand for HDI PCB manufacturing, XCEPCBhas served clients from many industries, including:
Automotive (Engine Control Units, GPS, Dashboard Electronics)
Computers (Laptops, Tablets, Wearable Electronics, Internet of Things - IoT)
Communication (Mobile phones, Modules, Routers, Switches)
Digitial (Cameras, Audio, Video)
FR-4 is the primary insulating backbone upon which the vast majority of rigid printed circuit boards (PCBs) are produced. A thin layer of copper foil is laminated to one or both sides of an FR-4 glass epoxy panel. These are commonly referred to as "copperclad laminates."
FR-4 copper-clad sheets are fabricated with circuitry interconnections etched into copper layers to produce printed circuit boards. More sophisticated and complex FR-4 printed circuit boards are produced in multiple layers, also known as "multilayer circuitry".
When ordering a copper clad laminate board, the FR-4 thickness and the copper foil thickness must be specified separately.
In the USA, FR-4 thickness is specified in thou or inches, and common thicknesses range from 10 thou (0.010 in, 254µm) to 3 inches (76 mm).
In the USA, copper foil thickness is specified in units of ounces per square foot (oz/ft2), commonly referred to simply as ounce. Common thicknesses are 1 oz/ft2(300 g/m2), 2 oz/ft2 (600 g/m2), and 3 oz/ft2 (900 g/m2). These work out to thicknesses of 34.1µm (1.34 thou), 68.2µm (2.68 thou), and 102.3µm (4.02 thou), respectively. Some PCB manufacturers refer to 1 oz/ft2 copper foil as having a thickness of 35µm (may also be referred to as 35 μ, 35 micron, or 35 mic).
1/0 - denotes 1 oz/ft2 copper one side, with no copper on the other side.
1/1 - denotes 1 oz/ft2 copper on both sides.
H/0 or H/H - denotes 0.5 oz/ft2 copper on one or both sides, respectively.
2/0 or 2/2 - denotes 2 oz/ft2 copper on one or both sides, respectively.
