Multilayer PCB or multilayer printed circuit boards are circuit boards composed of two or more conductive layers (copper layers). The copper layer is pressed together by the resin layer (prepreg). Due to the complexity of the multilayer PCB manufacturing process, low production volume, and difficulty in rework, their prices are relatively higher than a single layer and double-sided PCB.

Multilayer PCB Manufacturing

Due to the increase in the packaging density of integrated circuits, a high concentration of interconnection lines has resulted, which necessitates the use of multilayer PCB. Unforeseen design problems such as noise, stray capacitance, and crosstalk have appeared in the printed circuit layout. Therefore, the printed circuit board design must minimize the length of signal lines and avoid parallel routes. Obviously, in the PCB single-sided board, even the double-sided board, due to the limited number of crosses circuit that can be achieved, these requirements cannot be satisfied. In the case of a large number of interconnection and crossover requirements, the PCB circuit board must be expanded to more than two layers to achieve satisfactory performance. Thus a multilayer circuit board has appeared. Therefore, the original intention of manufacturing multilayer circuit boards is to provide more freedom in selecting appropriate wiring paths for complex and noise-sensitive electronic circuits.

Multilayer PCB circuit boards have at least three conductive layers, two of which are on the outer surface, and the remaining layer is integrated into the insulating board. The electrical connection between them is usually achieved through plated through holes on the cross-section of the circuit board. Unless specified, multilayer printed circuit boards are the same as double-sided boards, generally plated through-hole boards

Multilayer PCB increase board surface area through the addition of layers, decreasing overall size. This will allow higher-capacity multilayer PCB to be used in smaller devices, while high-capacity single PCB must be installed into larger products.

 Multilayer PCB can accomplish the same amount of work as multiple single-layer board, but does so at a smaller size and with fewer connecting components, reducing weight. This is an essential consideration for smaller electronics where weight is a concern.

Multilayer printed circuit is the product of electronic technology development in high speed, multi-function, large capacity, and small volume. With the continuous development of electronic technology, especially the extensive and in-depth application of large-scale and very large-scale integrated circuits, multilayer printed circuits are rapidly developing in the following directions: high density, high precision, and high layers, tiny lines and small holes, blind and buried holes, high plate thickness to aperture ratio and other technologies to meet market needs.

  • It can be manufactured in a PCB factory. The four-layer board generally uses a core with one copper foil on each sideand a three-layer board with one copper foil on one side. They must be pressed together.
  • The process cost difference between the two is that the four-layer board has one more copper foil and bonding layer. The cost difference is not significant. When the PCB factory makes a quote, they are generally quoted on an even number basis. Also, 3-4 layers are commonly quoted as a grade. (For example:If you design a 5-layer board, the other party will quote at the price of a 6-layer board. That is to say, the price you design for 3 layers is the same as the price you design for 4 layers.)
  • In the PCB process technology, the four-layer PCB board is better controlled than the three-layer board, mainly in terms of symmetry. The warpage of the four-layer board can be controlled below 0.7% (IPC600 standard), but the size of the three-layer board is large. At that time, the warpage will exceed this standard, which will affect the reliability of the SMT assembly and the entire product. Therefore, the designer shouldnot design the odd-numbered layer board. Even if the odd-numbered layer is necessary, it will be designed as a fake even-numbered layer. That is to design 5 layers into 6 layersand 7 layers into 8 layers.

Generally, do not use two PP sheets with high resin content together. If the inner layer of copper is too small, please use PP sheets with high resin content. 1080 PP sheets have the highest density and low resin content. Do not press single sheets as much as possible. Only 2 sheets of 2116 and 7630 PP sheets can be pressed into thick copper plates above 2OZ. The layer cannot be pressed by a single sheet of PP. 7628 PP sheet can be pressed by a single sheet, 2 sheets, 3 sheets, or up to 4 sheets.

Explanation of theoretical thickness calculation of multilayer PCB board after pressing,casino genting highland

Thickness after PP lamination = 100% residual copper lamination thickness-inner copper thickness*(1-Remaining copper rate%)

★ Lamination uses high temperature and high pressure to melt the prepreg by heat, make it flow, and turn it into a cured sheet. It is then processing one or more inner etched boards (Black Oxide Treatment) and copper foil into a multilayer board.

★ This process also includes layer stack-up before lamination, drill positioning holes, and profile routing after laminated multilayer boards.

Multilayer PCB is manufactured by stacking two or more circuits on top of each other, and they have reliable pre-set interconnections. Since drilling and plating have been completed before all layers are pressed together, this technique violates the traditional manufacturing process from the beginning. The two innermost layers are composed of traditional double panels, while the outer layers are different. They are composed of single independent panels. Before pressing, the inner substrate will be drilled, through-hole plated, pattern transferred, developed, and etched. The outer layer to be drilled is the signal layer, which is plated through so that a balanced copper ring is formed on the inner edge of the through-hole. The layers are then rolled together to form a multilayer PCB, which can be connected to each other (between components) using wave soldering.

Pressing may be done in a hydraulic press or an overpressure chamber (autoclave). In the hydraulic press, the prepared material (for pressure stacking) is placed under the cold or preheated pressure (high glass transition temperature material is placed at a temperature of 170-180°C). The glass transition temperature is the temperature at which an amorphous polymer (resin) or part of the amorphous region of a crystalline polymer changes from a hard and brittle state to a viscous, rubbery state.,world cup finals 2018

Multilayer Circuit Board
It is a container filled with high-temperature saturated water vapor, and high-pressure can be applied. The laminated substrate (laminates) sample can be placed in it for a period of time to force moisture into the board, and then take out the sample again. Place it on the surface of high-temperature molten tin and measure its “delamination resistance” characteristics. This word is also synonymous with the pressure cooker, which is commonly used by the industry. In addition, in the multilayer board pressing process, there is a “cabin press method” with high temperature and high-pressure carbon dioxide, which is also similar to this type of Autoclave Press.

It refers to the traditional lamination method of early multilayer PCB boards. At that time, the “outer layer” of MLB was mostly laminated and laminated with a single-sided copper thin substrate. It was not used until the end of 1984 when the output of MLB significantly increased. The current method is the copper-skin type large or mass pressing method (Mss Lam). This early MLB pressing method using a single-sided copper thin substrate is called cap lamination.,online casino games in malaysia

The multilayer board pressing often refers to the wrinkles that occur when the copper skin is improperly handled. Such shortcomings are more likely to occur when thin copper skins are below 0.5 oz and laminated in multiple layers.
It refers to the gentle and uniform sag on the copper surface, which may be caused by the partial protrusion of the steel plate used in pressing. If it shows a neat drop of the faulty edge, it is called “dish down.” If these shortcomings are left on the line after copper corrosion, the impedance of the high-speed transmission signal will be unstable, and noise will appear. Therefore, such a defect should be avoided as much as possible on the substrate’s copper surface.
When the multilayer board is pressed, in each opening of the press, there are often many “books” of bulk materials (such as 8-10 sets) of the board to be pressed. Each set of “bulk materials” (Opening) Book) must be separated by a flat, smooth, and hardened stainless steel plate. The mirror stainless steel plate used for this separation is called “caul plate” or “separate plate.” At present, AISI 430 or AISI 630 are commonly used.
Refers to the mass-produced multilayer board, the outer layer of copper foil and film are directly pressed with the inner skin, which becomes the mass lam of the multilayer board. This replaces the early traditional single-sided thin substrate Press legal.
When multilayer boards or substrate boards are laminated, kraft paper is often used as a heat transfer buffer. It is placed between the hot plate (Platern) of the laminator and the steel plate to ease the temperature rise curve closest to the bulk material. Between multiple substrates or multilayer boards to be pressed. Try to minimize the temperature difference of each layer of the sheet; the commonly used specifications are 90 to 150 pounds. Because the fiber in the paper has been crushed after high temperature and high pressure, it is no longer tough and difficult to function, so it must be replaced with a new one. This kind of kraft paper is co-cooked with a mixture of pinewood and various strong alkalis. After the volatiles escape and the acid is removed, it is washed and precipitated. After it becomes pulp, it can be pressed again to become rough and cheap paper material.
When the multilayer board is pressed and the plates are placed and positioned, they will start to heat and be lifted by the hottest layer from the bottom. Afterward, lift with a powerful hydraulic jack (ram) to press each opening (bulk materials in the opening) and are bonded together. At this time, the combined film (prepreg) begins to gradually soften or even flow, so the pressure used for the top extrusion cannot be too large. This is to avoid slippage of the sheet or excessive flow of the glue. This lower pressure (15-50 PSI) initially used is called “kiss pressure.” However, when the resin in the bulk materials of each film is heated to soften and gel and is about to harden. It is necessary to increase to the full pressure (300-500 PSI) so that the bulk materials are tightly combined to form a strong multilayer board.
Before pressing multilayer circuit boards or substrates, various bulk materials such as inner layer boards, films and copper sheets, steel plates, kraft paper pads, etc., need to be aligned, aligned, or registered up and down to prepare. Then it can be carefully fed into the pressing machine for hot pressing. This kind of preparatory work is called Lay Up. To improve the quality of multilayer boards, not only this kind of “stacking” work must be carried out in a clean room with temperature and humidity control, but also for the speed and quality of mass production. Generally, the large-scale press method (Mass Lam) in construction, even “automated” overlapping methods are needed to reduce human error. To save workshops and shared equipment, most factories combine “stacking” and “folding boards” into a comprehensive processing unit, so automation engineering is quite complicated.
