Excellent pcb assembly factory? 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. See extra information on pcb assembly service. The next layer is a thin copper foil, which is laminated to the board with heat and adhesive. On common, double sided PCBs, copper is applied to both sides of the substrate. In lower cost electronic gadgets the PCB may have copper on only one side. When we refer to a double sided or 2-layer board we are referring to the number of copper layers (2) in our lasagna. This can be as few as 1 layer or as many as 16 layers or more. The copper thickness can vary and is specified by weight, in ounces per square foot. The vast majority of PCBs have 1 ounce of copper per square foot but some PCBs that handle very high power may use 2 or 3 ounce copper. Each ounce per square translates to about 35 micrometers or 1.4 thousandths of an inch of thickness of copper.
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. 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.
In order to provide one-stop-services to customers, we can also provide FPC and Rigid-flex PCB Assembly service (also named SMT: Surface Mounting Technology). We can purchase all components from abroad or domestic market, and provide full products to you with short lead time. High Density Interconnects (HDI) board are defined as a board (PCB) with a higher wiring density per unit area than conventional printed circuit boards (PCB). They have finer lines and spaces (<100 µm), smaller vias (<150 µm) and capture pads (300, and higher connection pad density (>20 pads/cm2) than employed in conventional PCB technology. HDI board is used to reduce size and weight, as well as to enhance electrical performance.
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.
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.

Metal Core PCB means the core (base) material for PCB is the metal, not the normal FR4/CEM1-3, etc. and currently the most common metal used for MCPCB manufacturer are Aluminum, Copper and steel alloy. Aluminum has good heat transferring and dissipation ability, but yet relatively cheaper; copper has even better performance but relatively more expensive, and steel can be divided into normal steel and stainless steel. It more rigid than both aluminum and copper, but thermal conductivity is lower than them too. People will choose their own base/core material according to their different application.
