Multilayer PCB Board

  • High Precision Multilayer PCB Board suppliers

PCB, what we normal call as "printed circuit Board", is the basic for all electronics products. 

If we classify the PCB by layers, there will be single sided PCB, double sided PCB, and multilayer PCB Board.


Multilayer PCB Instructions by Linked Electronics


Multilayer PCB Board is made up of more than 2 copper layers, and those copper layers are boned by prepeg.  Conductor on different layers are connected with vias.

Compared with doubled sided layers, multilayer circuit board is smaller with higher capacity, faster speed, better durability and greater functionality. For BGA and QNF packages, electronic design engineer will use HDI multilayer PCB. 


By category in Linked Electronics, there are multilayer FR4 PCB, multilayer Rogers PCB, multilayer rigid flex PCBs, heavy copper multilayer PCB and HDI multilayer PCB board. 


Applications of Multilayer PCBs


Mulilayer PCB is used more and more in electronics industries becuse of its unique advantages.


Multilayer PCB boards is much more precise and has better performance than double sided PCBs, which is widely used in industrial, medical and communication industries.

What is the definition of Multilayer PCB electronic printed circuit board?
Multilayer PCB is the multi-layer printed circuit board that is composed of three or more electronic layers. This is made up of a substrate layer, which has a conductive metal on top and bottom sides. It also offers enhanced functionality. They are utilized in complex devices which require a very high number of connections.
Multilayer PCB boards includes at least three layers of conductive layers. This multilayer PCB laminating process means pressing FR4 core and PP together.
Both of them are laminated under high hydraulic press pressure and temperature condition. This process will melt prepreg which later make the prepreg to join these layers together.

Multilayer PCB Manufacturing Steps
The manufacturing process of multilayer circuits takes several complicated steps which much more difficult and complex than doubled sided PCBs.
PCB Layout--That is the process by customer engineer
Printed Circuit boards should be rigorously compatible with, a PCB layout created by the engineer designer using PCB design software. Here is some of the commonly-used PCB EDA software, Altium Designer, OrCAD, Pads, KiCad, Eagle etc. NOTE: Before the PCB fabrication, designers should inform their contract manufacturer about the PCB design software version used to design the circuit since it helps avoid issues caused by discrepancies.
Once the PCB design is approved for production, designers export the design into format that PCB manufacture accepts and the frequently used program is called extended Gerber in the format IX274X.
The PCB industry birthed extended Gerber as the perfect output format. Different PCB design software possibly calls for different Gerber file generation steps, they all encode comprehensive vital information including copper tracking layers, drill drawing, apertures, component notations and other options. All aspects of the PCB design undergo checks at this point. The software performs oversight algorithms on the design to ensure that no errors go undetected. Designers also examine the plan with regard to elements relating to track width, board edge spacing, trace and hole spacing and hole size.
After a thorough examination, designers forward PCB file to PC Board Houses for production. To ensure the design fulfills requirements for the minimum tolerances during manufacturing process, almost all PCB Fab Houses run Design for Manufacture (DFM) check before printed circuit board fabrication.
Printing of the PCB Design
PCB printing begins after designers output the PCB schematic files and manufacturers conduct a DFM check. The PCB manufacturers use a printer called a plotter, which makes photo films of the PCBs, to print circuit boards. PCB manufacturers will use the films to image the PCBs. Although it's a laser printer, it isn't a standard laser jet printer. Plotters use incredibly precise printing technology to provide a highly detailed film of the PCB design.
The final product results in a plastic sheet with a photo negative of the PCB in black ink. For the inner layers of PCB, black ink represents the conductive copper parts of the PCB. The remaining clear portion of the image denotes the areas of non-conductive material. The outer layers follow the opposite pattern: clear for copper, but black refers to the area that'll be etched away. The plotter automatically develops the film, and the film is securely stored to prevent any unwanted contact.
Each layer of PCB and solder mask receives its own clear and black film sheet. In total, a two-layer PCB needs four sheets: two for the layers and two for the solder mask. Significantly, all the films have to correspond perfectly to each other. When used in harmony, they map out the PCB alignment.
To achieve accurate alignment of all films, registration holes should be punched through all films. The exactness of the hole occurs by adjusting the table on which the film sits. When the tiny calibrations of the table lead to an optimal match, the hole is punched. The holes will fit into the registration pins in the next step of the imaging process.
Print the Copper Utilized for the Interior Layer
This step is the first while making the inner layer of the PCB. You print the multilayer PCB design; then copper is re-bonded to the FR4 or PP that serves as the PCB structure.
Discard unwanted copper
With the photo resist removed and the hardened resist covering the copper that needs to be kept, the board manufacturing steps into the next stage: unwanted copper removal. Just as the alkaline solution removed the resist, a more powerful chemical preparation wash away the excess copper. The copper solvent solution bath removes all of the exposed copper. Meanwhile, the desired copper remains fully protected beneath the hardened layer of photo resist.
Not all copper boards are created equal. Some heavy copper boards require larger amounts of copper solvent and varying lengths of exposure. As a side note, heavier copper boards require additional attention for track spacing. Most standard PCBs rely on similar specification.
Now that the solvent removed the unwanted copper, the hardened resist protecting the preferred copper needs washing off. Another solvent accomplishes this task. The board now glistens with only the copper substrate necessary for the PCB.
Lamination of the PCB Layers
AOI will be performed to check that there will be zero defects for the traces. Those can be bonded together. You can achieve this process in two spes, which includes the lay-up and the laminating.
The entire operation undergoes an automatic routine run by the bonding press computer. The computer orchestrates the process of heating up the stack, the point in which to apply pressure, and when to allow the stack to cool at a controlled rate.
Before you drill, the drill spot is located with an x-ray machine. This helps in securing the PCB stack.
PCB Plating
This process helps in fusing the different PCB layers making use of a chemical.
Imaging and Plating of the Outer Layer
By doing this you are guarding the copper found on the outer layer by applying the photoresist.
Final Etching
To protect the copper during the process, a tin guard is utilized. This gets rid of unwanted copper. This also ensures properly established PCB connections.
Applying Solder Mask
After cleaning the PCB panels, soldermask is applied onto both sides of the PCBs
Silk print is printed onto the PCBs
The nearly completed board receives ink-jet writing on its surface, used to indicate all vital information pertaining to the PCB. The PCB finally passes onto the last coating and curing stage.
Electrical and Testing Reliability
A technician performs electrical tests on the PCB. The automated procedure confirms the functionality of the PCB and its conformity to the original design. At linked electronics, we offer an advanced version of electrical testing called Flying Probe Testing, which depends on moving probes onto the pads to test electrical performance of each net on a bare printed circuit board. Another advanced testing is fixture which is faster but expensive for prototypes. The pins of the fixture will touch the pads and check the conformity of the boards.
Mechanic Process
PCBs will be routed as per customer’s mechanic file after flying probe test. For PCB using fixture test, the PCB will be routed out before mechanic process.
Final inspection will be performed. This includes board thickness, board warp and twist, any scratches etc. The errors rectified before it is sent for delivery.
Materials Used in the Manufacturing of Multilayer PCB
The different materials utilized in manufacturing multilayer PCBs are boards, copper foil, resin system, substrate, infused fiberglass sheet. Using an alternating sandwich, you can laminate these materials together.
All the planes of copper are etched and the plating through of all internal vias is done before the layers.
Multilayer PCB: Advantages
Multilayer PCBs come with lots of great benefits. Some of them include:
Higher assembly density
Provision of high speed and high capacity, as a result of their electrical properties
Weight reduction of devices
Elimination of connectors needed for multiple separate PCBs, thereby simplifying its construction.
