Premium metal core pcbs supplier? 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. Discover additional details at metal core pcbs.
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.
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.
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.
When the board has only copper tracks and features, and no circuit elements such as capacitors, resistors or active devices have been manufactured into the actual substrate of the board, it is more correctly referred to as printed wiring board (PWB) or etched wiring board. Use of the term PWB or printed wiring board although more accurate and distinct from what would be known as a true printed circuit board, has generally fallen by the wayside for many people as the distinction between circuit and wiring has become blurred.
Since beginning, as the printed circuit board manufacturers with best pcb assembly service 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. 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.

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.
The layer on top of the copper foil is called the soldermask layer. This layer gives the PCB its green (or, at PCB & MCPCB, red) color. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers. In the example below, the green solder mask is applied to the majority of the PCB, covering up the small traces but leaving the silver rings and SMD pads exposed so they can be soldered to. Soldermask is most commonly green in color but nearly any color is possible. We use red for almost all the PCB & MCPCB boards, white for the IOIO board, and purple for the Best Technology boards.
