According to the spacing: according to the line insertion: down, down, double-sided;
The welding methods with the PCB board are divided into: horizontal type, vertical paste type, horizontal type (also known as bent type), straight plug-in type (90 degrees perpendicular to the PCB board).
The material is generally made now, with LCP, 9T, and can generally be reflowed.
From the height of the product soldered on the PCB board, from,

When I first came into contact with this, everyone's idea was almost just to earn some pocket money, and there was no big requirement People's hearts are greedy, and they want to get something for nothing, so they have illusions, and they will fall deeper and deeper into it, and they will be out of control at most, more than 300,000 Fortunately, I met Mr. Chen (tos56s), who slowly came up with his rhythm, and I am very glad to meet such a person, and it makes me full of hope for life, and I am still confused, I can find him.

1. The relationship between FPC, PCB and FFC.
FPC refers to Flexible Circuit Board, PCB refers to Printed Circuit Board, and FFC refers to Flexible Flat Cable.
Flexible flat cables are often used in the circuits of flexible circuit boards and printed circuit boards, which are important electronic components and support for electronic components.
2. The difference between FPC, PCB and FFC.
1. The nature is different.
FPC: An FPC is a flexible circuit board.
PCB: A PCB is a type of printed circuit board.
FFC: FFC is a flexible flat cable.
2. The manufacturing process is different.
FPC: FPC is made of polyimide or polyester film as a substrate.
PCB: PCB is made through steps such as copper immersion, pattern transfer, pattern plating, stripping, etching, molding, etc., etc.
FFC: FFC is made of PET insulation material and extremely thin tinned flat copper wire, pressed together through a production line of high-tech automated equipment.
3. The characteristics are different.
FPC: FPC has the characteristics of high wiring density, light weight, thin thickness and good bendability.
PCB: PCB has the characteristics of high density, high reliability, designability, testability, and maintainability.
FFC: FFC has the characteristics of thin thickness, simple connection and easy disassembly.

PCB is a printed circuit copy board, or called hard board bai, the Chinese name is printed circuit board, also known as printed du circuit board, printed circuit zhi
The board is an important electronic component of DAO, the support of electronic components, and the provider of electrical connection of electronic components. Since it is made using electronic printing, it is called a "printed" circuit board.
FPC is a flexible circuit board, abbreviation"Flex boards", also known as"Flexible circuit boards", also called"Flexible circuit boards, flexible circuit boards"or"Flexible circuit boards, flexible circuit boards", English is"fpc pcb"or"fpcb,flexible and rigid-flex".
FFC is a flexible flat cable Flexible flat cable (FFC) is a new type of data cable made of PET insulation material and extremely thin tinned flat copper wire, pressed by high-tech automation equipment production line, with soft, random bending and folding, thin thickness, small size, simple connection, easy disassembly, easy to solve electromagnetic shielding (EMI) and other advantages.
In general: the PCB is hard, non-foldable, and can be distributed components; FPC is soft, flexible, and dispensable; FFC is a flexible connection line and cannot be arranged with components.

FPC is a socket and power strip, PCB is a printed BAI circuit board, and FFC is a kind of DU insulated ZHI material and extremely thin DAO tin-plated flat copper wire, referred to as soft.
Cable back. The FPC socket will be used in the answering process of the PCB sketchboard, and the connection between different PCB boards is connected by this FPC socket and the corresponding FFC cable in addition to ordinary wires.

Blood type. 1.Nutritional anemia.
It is mainly caused by the lack of hematopoietic raw materials in the body. The most common is iron deficiency anemia, which is caused by chronic blood loss, certain gastrointestinal disorders, long-term picky eating, etc. Secondly, due to the lack of vitamin B12, folic acid and other straightening raw materials, it causes nutritional megaloblastic anemia and pernicious anemia. >>>More
Paper is often seen in daily life, although it is a very commonly used paper, but there are many types of it, the first is letterpress printing paper, this quantitative is about 50 to 80 grams per square, usually used to print books. Then there is newsprint, which is called white newspaper, and the amount is about 51 grams, which is mainly used in newspapers or periodicals. Jiaozhen shouts board printing paper, the quantity is about 60 to 180 grams, coated paper, this quantitative is about 90 to 250 grams, this kind of can not be folded, it is very troublesome to restore after a slight crease. >>>More
