What is the Current Board



First, what is the current board, printed circuit boards and electronic products have become indispensable for the vast majority of the major components. Single, double-sided PCB manufacturing is in the substrate material - copper clad laminate (Copper- (2lad I.aminates, CCI) on selectively drilling, copper plating, copper plating, etching, etc. processing, to obtain the desired circuit pattern. Another multilayer printed circuit board manufacturing, but also within the core of thin copper-clad laminates as substrate, the conductive pattern layers and prepreg (Pregpr'eg) alternately laminated by a one-time bonding together to form a conductive pattern layer interconnect between three or more layers. Thus it can be seen as a substrate material in PCB manufacturing, either CCL or prepreg in the printed board plays a very important role. It has a conductivity, insulation and support three aspects of the function. PCB performance, quality, manufacturing workability, manufacturing cost, the manufacturing level, etc., depends largely on the substrate material.

Second, the development history of the substrate substrate material and production technology, has gone through half a century of development, the world's annual output has reached 290 million square meters, the development time by electronic machine products, semiconductor manufacturing technology, electrical installation technology, printed circuit board technology innovative development driven from CCL 1943 phenolic resin substrate made into practical since the beginning of the development of the substrate material very quickly. In 1959, Texas Instruments Inc. to produce the first integrated circuit, for printing board of a higher high-density assembly requirements, thus contributing to the plywood production. In 1961, the United States Hazeltine Corpot ation company successfully developed a metal vias technology law multilayer technology. 1977 resin, BT resin to achieve a industrial production, to the world and provides a multilayer development of new low Tg substrate material. 1990 IBM Japan announced a photosensitive resin as the insulating layer laminated multilayer technology law, in 1997, including laminated plywood, including high density multilayer interconnect technology to develop maturity. At the same time, in order to BGA, CSP is a typical representative of the plastic package substrate has been rapid development. Late, some of the free bromine, antimony and other new green flame retardant board is rising rapidly in the 1990s, to the market. Of the substrate material already 40 years of development, it has formed the production scale of about 90 billion yuan in output value. In 2000, China's mainland CCL production has reached 64 million square meters, the output value of 5.5 billion yuan. In which the paper-based CCL production has ranked third in the world. But in technology, product varieties, particularly the development of new substrate, with foreign advanced countries there are still a considerable gap.

Third, the classification of the general PCB board substrate materials can be divided into two categories: rigid substrate material and the flexible substrate material. Important species is generally rigid substrate materials CCL. It is the reinforcing material (Reinforeing Material), impregnated with resin adhesive, by drying, cutting, folding synthesis blank, then covered with foil, with steel as a mold, in a high temperature and pressure in a hot press forming in the system into. Multilayer prepreg general use, it is CCL semi-finished products in the production process (mostly glass cloth impregnated with resin, dried processed). There are several classifications of copper clad board. Usually by reinforcing material plate is different, it can be divided into: paper-based, glass fiber cloth, composite matrix (CEM series), laminated plywood base and specialty materials group (ceramics, metal core group, etc.) five categories. If you press the resin adhesive plate used to classify different common paper-based CCI. They are: various types of phenolic resin (XPc, XxxPC, FR a 1, FR-2, etc.), epoxy resin (FE-3), a polyester resin. Common glass fiber cloth CCL epoxy (FR-4, FR-5), which is a glass fiber cloth type most widely used. There are also other particularity resin (glass fiber cloth, poly amide fibers, non-woven material is increased): modified bismaleimide triazine resin (BT), polyimide resin (PI) , diphenylene ether resin (PPO), maleic anhydride imide - styrene resin (MS), polycyanate ester resin, a polyolefin resin or the like. CCL by flame retardant classification can be divided into flame retardant (UL94 a VO, UL94 a V1 level) and non-flame retardant (UL94 HB level a) two boards. Nearly two years, with more emphasis on environmental issues, the flame-retardant CCL CCL in turn branch breed a new bromine-free material, it can be called "green flame retardant cCL". With the rapid development of electronic products and technology, to cCL higher performance requirements. Therefore, the performance of CCL classification, divided into general performance CCL, low dielectric constant CCL, high heat resistance, CCL (general board of L at above 150 ℃), low thermal expansion coefficient of the CCL (generally used on the package substrate ) and other types.

Multilayer flexible PCB


Multilayer PCB soft as rigid as a multilayer PCB, multilayer lamination technology, can be made into a multi-layer flexible PCB. The easiest multilayer soft-sided PCB PCB is covered with two layers of copper on both sides to form a shield of three soft PCB. This is equivalent to three soft PCB coaxial wire or shield wire on the electrical characteristics. The most common structure is a four-layer PCB multilayer flexible structure with metallized holes to achieve the interconnection between layers, the middle floor general is the power and ground planes.

Advantages multilayer PCB soft base film is lightweight and has excellent electrical characteristics, such as low dielectric constant. Multilayer flexible PCB board made of polyimide film to the substrate than the weight of rigid epoxy glass cloth multi-layer PCB board about 1/3 lighter, but it lost its single-sided, double-sided flexible PCB fine The flexible, most of these products are not required to be flexible.
Multilayer PCB soft can be further divided into the following types:

1) is formed on a flexible insulating substrate a multilayer PCB, which is defined as the finished product can flex: This structure is usually one or both sides of the microstrip many flexible PCB bonded to both surfaces of the end, but its center and bonding together the end portions, so as to have a high degree of flexibility. In order to have the desired electrical characteristics, such as characteristic impedance performance and rigid PCB interconnect it matches, each wire layer of the multilayer flexible PCB components, the design must be in ground contact surface of the signal line. In order to have a high degree of flexibility, the layer may be a thin wire, a suitable coating, such as polyimide, instead of a thick layer of laminated cover layer. Z metallized holes so that the surface between the flexible wiring layer may achieve the desired interconnection. This multi-layer flexible PCB best suited for applications requiring flexibility, high reliability and high density designs.

2) constituting the multilayer PCB in the flexible insulating substrate, the end of which the finished product can be predetermined deflection: These soft multi-layer flexible PCB is an insulating material, such as a polyimide film, a laminate made of plywood. After lamination losing inherent flexibility. When the design requirements to maximize the use of the insulating film properties, such as low dielectric constant, the thickness of the homogeneous medium, light weight and capable of continuously processing characteristics, on the use of such a flexible PCB. For example, a polyimide film with a multilayer PCB insulating material about epoxy glass cloth weight is lighter than the third rigid PCB.

3) constituting the multilayer PCB in the flexible insulating base material, the finished product must be shaped, rather than continuous flexing: These soft multi-layer PCB is formed of a soft insulating material. Although it uses a soft material, but due to restrictions of the electrical design, as for the required conductor resistance, require a thick conductor, or for the desired impedance or capacitance, between the request signal layer and the ground layer has a thickness The insulating spacer, therefore, it is applied when the finished product has been formed. The term "formable" is defined as: a multi-layer flexible PCB member has the ability to make a desired shape, and in the application can not be deflected. Application avionics unit internal wiring. In this case, the requirements of the stripline conductor or three-dimensional design of low resistance, capacitive coupling or circuit noise and minimal interconnection end portion can be smoothly curved in a 90 °. Multilayer PCB soft polyimide film material implements this routing tasks. Because high temperature polyimide film, there are flexible, and good overall electrical and mechanical characteristics. To achieve this all the interconnecting member section, wherein the alignment portion is further divided into a plurality of multi-layer flexible circuit member, and together with the adhesive tape to form a printed wiring bundle.
