Printed circuit board factory manufacturer right now: Today printed wiring (circuit) boards are used in virtually all but the simplest commercially produced electronic devices, and allow fully automated assembly processes that were not possible or practical in earlier era tag type circuit assembly processes. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB Assembly (PCBA). In informal use the term “PCB” is used both for bare and assembled boards, the context clarifying the meaning. The IPC preferred term for populated boards is CCA, circuit card assembly. This does not apply to backplanes; assembled backplanes are called backplane assemblies by the IPC. Find even more information at best pcb assembly.
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.
There are ultra-thin rigid PCB materials for applications requiring a 2D printed circuit board. They are usually applied as packaging substrates for integrated circuits, in which they aid in making the whole component extremely thin. You can attain 25 microns wide spaces or lines, pitches below 175 microns, and 50 and 100 microns vias and pads diameters respectively. Also referred to as flex ultra-thin PCB, this is a type of extra-thin PCB manufactured using flexible laminates.
Multilayer printed circuit boards (PCBs) consist of three or more layers of conductive material, usually copper, separated by insulating layers. Small holes filled with conductive material called vias interconnect the layers. Multilayer PCBs offer the same advantages as double-layer PCBs but have even more routing options and the ability to place components on multiple layers. Rigid printed circuit boards (PCBs) are solid sheets of insulating material, typically fiberglass, with copper traces etched into them. The finished boards are very strong and can withstand high temperatures and mechanical stress. Rigid PCBs are for applications where reliability and durability are critical, such as in military and aerospace applications.
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.

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. Quality Policy: PCB Quality is the core of products. All of engineer & vital department guys has more than five years expenrience in PCB industry, we follow up the default PCB standard, as well as with clients’ special request.
A significant advance was the development of wire wrapping, where a small gauge wire is literally wrapped around a post at each connection point, creating a gas-tight connection which is highly durable and easily changeable. As electronics moved from vacuum tubes and relays to silicon and integrated circuits, the size and cost of electronic components began to decrease. Electronics became more prevalent in consumer goods, and the pressure to reduce the size and manufacturing costs of electronic products drove manufacturers to look for better solutions. Thus was born the PCB.
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.
