metal core pcbs factory manufacturer right now? Flex printed circuit boards (PCBs) are flexible sheets of insulating material, typically polyimide, with copper traces etched into them. The finished panel can be bent or flexed without damage. Flex PCBs are for applications where space is limited, and flexibility is required, such as in mobile phones and wearable electronics. There are many different types of printed circuit boards (PCBs), each with advantages and disadvantages. The type of PCB that is best suited for a particular application depends on the requirements of the application. Find more info on fr4 pcb manufacturer.
Sometimes people will use abbreviation “MCPCB”, instead of the full name as Metal Core PCB, or Metal Core Printed Circuit Board. And also used different word refers the core/base, so you will also see different name of Metal Core PCB, such as Metal PCB, Metal Base PCB, Metal Backed PCB, Metal Clad PCB and Metal Core Board and so on. MCPCBs are used instead of traditional FR4 or CEM3 PCBs because of the ability to efficiently dissipate heat away from the components. This is achieved by using a Thermally Conductive Dielectric Layer.
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.
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.
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.

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.
