Excellent Ultra thin core pcb factory: Flexible printed circuit boards (PCBs) are so named because they are flexible enough to fit any electronic device irrespective of its size or shape. With miniaturization as a growing trend as far as electronics equipment is concerned, the importance of flexible PCBs cannot be overstated. The significant advantage that Flexible Circuit Boards offer includes the fact that they help keep the size and weight of the equipment under control besides improving their ability to withstand high temperatures. Some of the characteristics that differentiate flexible printed circuit boards include their distinct circuitry, unique component arrangement, and use of malleable base materials.

Generally speaking, aluminum is the most economic option considering thermal conductivity, rigidness, and cost. Therefore, the base/core material of normal Metal Core PCB are made of aluminum. In our company, if not special request, or notes, the metal core refer will be aluminum, then MCPCB will means Aluminum Core PCB. If you need Copper Core PCB, Steel Core PCB, or Stainless steel core PCB, you should add special notes in drawing.
What is Ultra-Thin HDI PCB? High-Density Interconnect PCB is simply an ultra-thin PCB having more counts of interconnections, covering minimal space, leading to circuit board miniaturization. The components of HDI PCB are positioned closer, reducing the board space significantly but not compromising its performance. HDI is among the fastest advancing PCB technologies, capable of integrating smaller capture pads and vias and higher densities of connection pad. HDI PCBs have buried and blind vias and usually comprise of microvias with diameter of 0.006 or lower. Extra thin HDI PCBs provide better construction, layout and design choices by integrating outstanding features like microvias.
Let’s take a closer look at the different types of PCBs and how they work. Whether you’re a first-time PCB buyer or a seasoned electronics engineer, read on to learn more about these fascinating components! Single-sided printed circuit boards (PCBs) are the most basic and simplest type of PCBs. They consist of a single layer of conductive material, typically copper, which is etched to form the desired circuitry. The unetched side of the board is generally covered with a non-conductive material, such as solder mask, to prevent short circuits. Single-sided PCBs are for simple applications where the circuitry is not too complex.
Most of our engineer and operators has more than ten years of experience in PCB industry, so we can produce special such as 20 OZ heavy copper board, 4 layers MCPCB, etc. At the same time, we purchased many advanced, art-of-state machines & devices for PCB manufacturing, checking, to improve the quality of our boards.

A single sided flexible printed circuit (1 layer flex circuit) is a flex circuit with one layer of copper trace on one substrate, and with one layer Polyimide coverlay laminated to copper trace so that only one side copper will be exposed, so that it only allowing access to copper trace from one side, comparing to dual access flex circuit which allows access from both top and bottom side of flex circuit. As there’s only one layer of copper trace, so it also named as 1 layer flexible printed circuit, or 1 layer flexible circuit, or even 1 layer FPC, or 1L FPC. The multi layer flex circuit refer to a flex circuit with more than 2 layer circuit layers. Three or more flexible conductive layers with flexible insulating layers between each one, which are interconnected by way of metallized hole through the vias/holes and plating to form a conductive path between the different layers, and external are polyimide insulating layers. Equipment: We purchased many advanced, art-of-state machines & devices for PCB manufacturing, checking, to improve the quality of our boards.
The next layer is a thin copper foil, which is laminated to the board with heat and adhesive. On common, double sided PCBs, copper is applied to both sides of the substrate. In lower cost electronic gadgets the PCB may have copper on only one side. When we refer to a double sided or 2-layer board we are referring to the number of copper layers (2) in our lasagna. This can be as few as 1 layer or as many as 16 layers or more. The copper thickness can vary and is specified by weight, in ounces per square foot. The vast majority of PCBs have 1 ounce of copper per square foot but some PCBs that handle very high power may use 2 or 3 ounce copper. Each ounce per square translates to about 35 micrometers or 1.4 thousandths of an inch of thickness of copper.
Tg means Glass Transition Temperature. As flammability of printed circuit board (PCB) is V-0 (UL 94-V0), so if the temperature exceeds designated Tg value, the board will changed from glassy state to rubbery state and then the function of PCB will be affected. If working temperature of your product is higher than normal (130-140C), then have to use High Tg PCB material which is > 170C. and popular PCB high value are 170C, 175C, and 180C. Normally the FR4 circuit board Tg value should be at least 10-20C higher than working temperature of product. If you 130TG board, working temperature will be lower than 110C; if use 170 high TG board, then maximum working temperature should be lower than 150C.
