Pcb assembly provider today? 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. Read additional information at thin core pcb. 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.

A single sided flexible printed circuit (1 layer flex circuit) is a flex circuit with one layer of copper trace on one substrate, and with one layer Polyimide coverlay laminated to copper trace so that only one side copper will be exposed, so that it only allowing access to copper trace from one side, comparing to dual access flex circuit which allows access from both top and bottom side of flex circuit. As there’s only one layer of copper trace, so it also named as 1 layer flexible printed circuit, or 1 layer flexible circuit, or even 1 layer FPC, or 1L FPC. The multi layer flex circuit refer to a flex circuit with more than 2 layer circuit layers. Three or more flexible conductive layers with flexible insulating layers between each one, which are interconnected by way of metallized hole through the vias/holes and plating to form a conductive path between the different layers, and external are polyimide insulating layers. Capability: We are continued to improve our MCPCB, FR4 PCB & FPC & Ceramic PCB manufacturing level to get satisfactory result from customers and ourselves.

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.

Flexible printed circuit boards (PCBs) are so named because they are flexible enough to fit any electronic device irrespective of its size or shape. With miniaturization as a growing trend as far as electronics equipment is concerned, the importance of flexible PCBs cannot be overstated. The significant advantage that Flexible Circuit Boards offer includes the fact that they help keep the size and weight of the equipment under control besides improving their ability to withstand high temperatures. Some of the characteristics that differentiate flexible printed circuit boards include their distinct circuitry, unique component arrangement, and use of malleable base materials.

Best Technology wholesale fr4 pcb manufacturer specialized in many kinds of fr4 board and provides fr4 pcb assembly service since 2006. Please contact Best Technology fr4 board suppliers anytime and get quotes! FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). After add copper layer on one or each side FR4, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal printed cricuit board (PCB). Printed circuit board using FR4 as core material will be named as “FR4 PCB”. Wholesale fr4 pcb board is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on. Discover even more information at https://www.bstpcb.com/.

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.

Flat Flexible Cable (FFC) is made of PET insulation material and extremely thin tinned flat copper wire, it has free bending and folding, thin thickness, small size, simple connection, easy to solve electromagnetic shielding (EMI). Common ffc cables’ specifications are 0.5mm, 0.8mm, 1.0mm, 1.25mm, 1.27mm, 1.5mm, 2.0mm, 2.54mm and other various pitches to match different types of connectors. Rigid-flex PCB is a circuit board combined of rigid board and flexible circuit, from 2 layer to 50 layers, has the advantage of rigidness, flatness, flexibility and bendability. You can see advantage of rigid flex circuit such as design high density, less components need, less space, and stack up. Welcome to visit Best Technology rigid flex pcb manufacturers.

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.

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.
