Ultra thin core pcb factory manufacturer today? But sometimes, limited to space or margin, or needed by design purpose, people need much thinner thickness such as 0.25 mm, 0.20 mm, or even 0.15 mm, so that the PCB can be used in such as SIM card, sensor card, and so on. Because of extreme thickness, extra thin PCB, or very thin PCB name came out. Different with the flexible PCB, extra thin PCB refers to a PCB substrate made by FR4 materials. But if you need board thickness less than 0.10 mm, then you should use flexible circuit which can be 0.06 mm for 1L FPC or 0.10 mm for 2L FPC. Find extra details at best pcb manufacturer in china.
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.
What we provide is not only PCB & MCPCB manufacturing, but also including PCB duplicating, Engineering & process design, components management & sourcing solution, PCB in house assembly & full system integration, surface mounted technology (SMT), full products assembly & testing.
Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.
The design, as well as the manufacture of flexible PCBs, is a very nimble job. Seemingly minor errors such as two metal traces not being insulated on a high-voltage board, for example, can result in an arc leading to the destruction of the circuit. Errors in manufacturing can come by way of wrong selection of materials, improper design, and other such factors that can result in the capability of the flexible PCB to bend and take the required shape. If the PCB tends to fall from a height or any other external forces such as frequent plugging and unplugging of the PCB, it can cause damage to your PCB. Unreliable and faulty components can damage the board in many ways. One of them is the fact that they are unable to protect the PCB from overheating.
According to different manufacturing method, current there’re three basic types for ceramic board: A) Thick Film Ceramic Board Thick Film Ceramic PCB: Using this technology, the thickness of conductor layer exceeds 10 micron, more thick than spurting technology. The conductor is silver or gold palladium, and was printed on ceramic substrate. More for Thick Film Ceramic PCB. B) DCB Ceramic Board DCB (Direct Copper Bonded) technology denotes a special process in which the copper foil and the core (Al2O3 or ALN), on one or both sides, are directly bonded under appropriate high temperature and pressure.

Double sided flex circuits consists with double sided copper conductors and can be connected from both sides. It allows more complicated circuit designs, more components assembled. The major material used are copper foil, polyimide and coverlay. Adhesiveless stack up is popular for better dimensional stability, high temperature, thinner thickness. Dual access flexible circuit board refer to the flex circuit which can be accessed from both top and bottom side but only has only layer of conductor trace. Copper thickness 1OZ and coverlay 1mil, it similar with 1 layer FPC and opposite side FFC. There’re coverlay openings on both sides of flex circuit so that there’re solderable PAD on both top and bottom sides, that is similar with double sided FPC, but dual access flex circuit board has different stack up because of only one copper trace, so no plating process is need to make plated through hole (PTH) to connect between top and bottom side, and trace layout is much more simple. Currently our mouthy capability is 260,000 square feet (28,900 square meter), more than 1,000 different boards will be completed. We also provide expediate service, so that urgent boards can be shipped out within 24 hours.
A PCB is sort of like a layer cake or lasagna- there are alternating layers of different materials which are laminated together with heat and adhesive such that the result is a single object. The base material, or substrate, is usually fiberglass. Historically, the most common designator for this fiberglass is “FR4”. This solid core gives the PCB its rigidity and thickness. There are also flexible PCBs built on flexible high-temperature plastic (Kapton or the equivalent). You will find many different thickness PCBs; the most common thickness for PCB & MCPCB products is 1.6mm (0.063″). Some of our products- Best Technology boards and Arudino Pro Micro boards- use a 0.8mm thick board.
In order to provide one-stop-services to customers, we can also provide FPC and Rigid-flex PCB Assembly service (also named SMT: Surface Mounting Technology). We can purchase all components from abroad or domestic market, and provide full products to you with short lead time. High Density Interconnects (HDI) board are defined as a board (PCB) with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces (<100 µm), smaller vias (<150 µm) and capture pads (300, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology. HDI board is used to reduce size and weight, as well as to enhance electrical performance.
