Mcpcb manufacturer from China? The best fr4 board series is available in a wide range of types and specifications. Best Technology fr4 manufacturer carefully selects quality raw materials. Production cost and product quality will be strictly controlled. This enables us to produce fr4 PCB which is more competitive than other products in the industry. It has advantages in internal performance, price, and quality. If you’ve ever wondered what those green, brown, or black boards inside your electronic devices are, you’re not alone. These boards are called printed circuit boards (PCBs), and they play a vital role in the function of nearly all electronic devices. See more information at mcpcb manufacturers.
Advantage of MCPCB: Some LEDs dissipate between 2-5W of heat and failures occur when the heat from a LED is not properly removed; a LED’s light output is reduced as well as degradation when the heat remains stagnant in the LED package. The purpose of a MCPCB is to efficiently remove the heat from all topical IC’s (not just LEDs). The aluminum base and thermally conductive dielectric layer act as bridges between the IC’s and heat sink. One single heat sink is mounted directly to the aluminum base eliminating the need for multiple heat sinks on top of the surface mounted components.
Since beginning, as a printed circuit board (PCB) vendor in Asia, Best Technology is dedicating to be your best partner of advance, high-precision printed circuit boards, such as heavy copper boards, ultra thin PCB, mixed layers, high TG, HDI, high frequency (Rogers, Taconic), impedance controlled board, Metal Core PCB (MCPCB) such as Aluminum PCB, Copper PCB, and Ceramic PCB (conductor Copper, AgPd, Au, etc) and so on.
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.
Today printed wiring (circuit) boards are used in virtually all but the simplest commercially produced electronic devices, and allow fully automated assembly processes that were not possible or practical in earlier era tag type circuit assembly processes. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB Assembly (PCBA). In informal use the term “PCB” is used both for bare and assembled boards, the context clarifying the meaning. The IPC preferred term for populated boards is CCA, circuit card assembly. This does not apply to backplanes; assembled backplanes are called backplane assemblies by the IPC.

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. Quality Policy: PCB Quality is the core of products. All of engineer & vital department guys has more than five years expenrience in PCB industry, we follow up the default PCB standard, as well as with clients’ special request.
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.
