Top printed circuit board factory? Rigid flex printed circuit boards (PCBs) are a combination of rigid and flexible boards. The rigid board is typically made from fiberglass, and the flexible board is generally polyimide. Both are etched with copper before they are bonded together with an adhesive. The finished panel is very strong and can flex without damage. Rigid flex PCBs are for applications where space is limited, and flexibility is required, such as in mobile phones and wearable electronics.

The main difference between a FR4 board and MCPCB is the thermal conductivity dielectric material in the MCPCB. This acts as a thermal bridge between the IC components and metal backing plate. Heat is conducted from the package through the metal core to an additional heat sink. On the FR4 board the heat remains stagnant if not transferred by a topical heatsink. According to lab testing a MCPCB with a 1W LED remained near an ambient of 25C, while the same 1W LED on a FR4 board reached 12C over ambient. LED PCB always be produced with Aluminum core, but sometimes steel core PCB also be used.
Best Technology, establish on June 28, 2006, is a Hong Kong registered company whom focused on one-stop solution provider of FPC, Rigid-flex, MCPCB, FR4 PCB, Ceramic PCB, Special PCB such as Heavy Copper (up to 20 OZ), extra thin PCB (0.10, 0.15mm), and PCB assembly service.
Heavy Copper Board does not have a set of definition per IPC. According to PCB industry, however, peopel generally use this name to identify a printed circuit board with copper conductors 3 oz/ft2 – 10 oz/ft2 in inner and/or outer layers. And Extreme heavy copper PCB refers to 20 oz/ft2 to 200 oz/ft2 printed circuit board. Heavy copper normally used for a various products but not limited to: high power distribution, heat dissipation, planar transformers, power convertors, and so on.
While Flexible PCBs offer significant advantages, they are also prone to damages. Broadly damages can accrue from two factors: environmental factors and problems that account for issues at the design/fabrication stages. Let us look at both these aspects in some detail. Several environmental factors can cause damage to PCBs, including moisture, static electricity, dust, extreme temperatures, chemical corrosion, and pests. For example, if the PCB is stored in an environment with a lot of moisture, it can destroy the flexible PCB. Moisture can result in a short. Also, given that molds can grow in a damp environment, it will result in a circuit failure. The storage area must be free of any static creating agents. Storing PCBs in carpeted rooms, for example, can result in damage to printed circuit boards on account of the static electricity generated.

Best Through Hole Technology assemble more than 50 kinds components Factory Price. We offer a complete range of through hole PCB assembly capabilities in compliance with IPC quality standards. We provide Through Hole Technology (THT) PCBA service at the highest quality level and in a cost-effective manner. Our through hole technology (THT) PCB Assembly services includes both manual and automated techniques. While our manual soldering techniques can handle complex assemblies, the automated ones are best suited for high volume production as well as reduced material handling. We provide THT PCBA service at the highest quality level and in a cost-effective manner. Art-of-state Technology: 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 layer MCPCB, etc.
Cheaper PCBs and perf boards (shown above) will be made with other materials such as epoxies or phenolics which lack the durability of FR4 but are much less expensive. You will know you are working with this type of PCB when you solder to it – they have a very distictive bad smell. These types of substrates are also typically found in low-end consumer electronics. Phenolics have a low thermal decomposition temperature which causes them to delaminate, smoke and char when the soldering iron is held too long on the board.
