Heavy Copper PCB

Thick copper PCBs can achieve higher density and minimize the number of layers, resulting in a simple and durable structure. They pack more conductive material into less space, providing greater mechanical strength for the connector. Copper’s high thermal conductivity lets it draw heat away from the PCB’s temperature-sensitive components, keeping them in better condition.

HEAVY COPPER PCB
HDI PCB

HDI PCB

Compared with standard PCB boards, HDI PCBs are constructed using thin materials and minimal layers, which improves the performance and efficiency of HDI PCB boards. Therefore, the HDI PCB layout is very suitable for complex small designs. Compared with traditional circuit boards, HDI PCB helps reduce size and weight and enhance the device’s electrical performance.

RIGID-FLEX PCB

Rigid-Flex PCB

Rigid-Flex PCB is a circuit board that combines flexible and rigid circuit board technologies. Most rigid-flex boards consist of a multi-layer flexible circuit substrate connected externally or internally to one or more rigid circuit boards, depending on the application’s design. Its design is suitable for any area. Since it can be folded, it is suitable for smaller devices.

Ceramic PCB

Unlike traditional FR-4, ceramic PCB has good high-frequency performance, high thermal conductivity, high insulation, high voltage, and other properties that organic substrates do not have. Therefore, ceramic PCBs are extremely adaptable and can replace complete standard printed circuit boards with simpler structures and higher performance.

CERAMIC PCB

FR4 Printed Circuit Board

Most printed circuit boards are manufactured using glass-reinforced epoxy laminates as the substrate. While there are a variety of laminates on the market, FR-4 is versatile and widely specified as the standard material for PCB manufacturing. FR-4 is used as an electrical insulator with a good strength-to-weight ratio, flame retardancy, and high dielectric strength.

FR4 PRINTED CIRCUIT BOARD
ALUMINUM PCB

Aluminum PCB

Aluminum substrates are one of the most thermally conductive PCB options. Aluminum PCB has excellent electrical insulation and good thermal potential. Aluminum baseplates offer a high level of physical durability, reducing the risk of breakage. In addition to being affordable, aluminum has a relatively low environmental impact compared to other metals.

Our PCB manufacturing process and technology

1. Design PCB

Any PCB manufacturing starts with a design: the designer creates a blueprint for the PCB to be manufactured to meet all the requirements outlined by the customer. Commonly used PCB design software includes Altium Designer, Extended Gerber, OrCAD, Pads, KiCad, Eagle, etc.

After the designer does all the checks, the completed PCB design file is sent to the fabricator. After arriving at the PCB fabrication plant, the fabricator will check the PCB design plan for a second time, called Design for Manufacturing (DFM) check. Manufacturability DFM checks to ensure that the PCB design meets at least the minimum tolerances required in the manufacturing process, then prepares it for the next step in the design process: design review and engineering issues.

2、Design Check

Another critical step in the PCB manufacturing process: checking the design for potential errors or defects. Engineers perform design reviews and inspect every part of the PCB design to ensure no missing components or defective structures. After getting permission from the engineer, the design goes to the printing stage.

3、Print PCB Design

After the engineer completes all checks, the PCB design blueprint can be printed. Unlike other design drawings, such as construction site drawings, PCB drawings will not be printed on ordinary A5 paper. Instead, use a special printer to print. We call it a PCB drawing printer. Graphic printers make design drawings of PCBs. The final product of this blueprint looks a lot like the transparencies we used to use in school – it’s essentially a negative of the whiteboard itself.

Each PCB layer and accompanying solder mask has its thin film, so a simple two-layer PCB requires four sheets – one for each layer and one for each of the accompanying solder masks.

After the films are printed, they are lined up, and a hole is punched in them using a hole punch called a pilot hole. The registration holes guide the film’s alignment later in the process.

4、Inner Layer Printed Copper

After the PCB design is printed onto a piece of laminate material, a layer of copper foil or coating is applied. The copper is then pre-bonded to the same laminate used as the structure of the PCB. The copper is then etched away to reveal the previous blueprint.

Next, the laminate is covered with a photosensitive film called resist. Resists are made from a layer of photoreactive chemicals that harden after exposure to ultraviolet light. The resist allows technicians to perfectly match the blueprint photo and what is printed onto the photoresist.

Once the resist and laminate are lined up – using the holes from before – they are hit with UV light. UV light passes through the translucent portion of the film, hardening the photoresist. This represents the copper area to be reserved as a channel. In contrast, black ink prevents any light from entering areas that are not intended to harden so that they can be removed later.

After the board is ready, it is washed with an alkaline solution to remove any residual photoresist. The board is then pressure washed to remove anything left on the surface and left to dry.

After drying, the only resist that should remain on the PCB is on top of the copper, and when it finally pops off, the copper remains as part of the PCB. A technician checks the PCB to make sure there are no errors. If there are no errors, you can go to the next step.

5、Copper Removal

A printed circuit board’s core or inner layers need excess copper removed before the next step in the PCB manufacturing process. Etching involves covering the necessary copper on the board and exposing the rest of the board to chemicals. The unprotected copper on the PCB can be removed using a chemical etching process, leaving only the essential parts of the board.

The timing of this step or the amount of copper etch solvent used will vary depending on the board construction. Larger or more complex PCBs may use more copper, resulting in excess copper that must be etched to remove. Therefore, these boards will require more time and solvent.

6、Align Layers

After cleaning each layer of the PCB, we can proceed to layer alignment and optical inspection. The holes in the front align the inner and outer layers. To align the layers, tech fabricators place them on a type of punch called an optical punch. The optical punching machine drives a pin down through the hole to align the layers of the PCB.

7、Optical Detection

After the PCB layers are optically drilled, another machine optically inspects them to make sure there are no defects. This automated optical inspection step is important because any errors in the inner layers cannot be corrected once the layers are put together. The AOI machine uses a laser sensor to scan the layers to compare the PCB to the Gerber file of the original design model.

After the AOI machine has inspected the PCB layer—that is, neither the technician nor the AOI machine found any defects—it goes to the final steps of PCB manufacturing.

AOI is critical to the manufacture of printed circuit boards. Without it, boards can suffer from various problems, such as not meeting design specifications or having excess copper not removed during the etch process. These boards may go through the rest of the manufacturing process. AOI prevents defective boards from continuing to be produced by conducting quality inspections during production.

8、Laminated PCB

At this stage, the circuit board needs to be laminated. All the individual PCB layers are waiting for their bonding. As long as it is confirmed that there are no defects in these layers, the fusion can be performed. The outer layer must be bonded to the substrate. The process is performed in two steps: layering and fusion.

The outside of the PCB is made of fiberglass pre-impregnated/pre-coated with epoxy. The original part of the substrate is also covered with a thin layer of copper foil, which now contains the etching of the copper traces. Once the outer and inner layers are ready, it’s time to bring them together to blend.

9、Drilling

To find the exact location of the drill hole, the X-ray machine locator identifies the correct drill target point. Then, drill the appropriate pilot holes to secure the PCB stack-up layers. Before drilling, the technician places a slab of cushioning material under the drill target to ensure a clean hole. The exit material prevents any unwanted tearing at the bit exit. Any extra copper remaining at the edges will be removed after the drilling.

10、Plating

After the panel has been drilled, it is ready for electroplating. The plating process uses chemicals to fuse all the different layers of the PCB. After thorough cleaning, the PCB is dipped in a series of chemicals. Part of the manufacturing process is to coat the panel with a micron-thick layer of copper, deposited on top and into the holes that have just been drilled.

They are simply used to expose the fiberglass substrate that makes up the inside of the panel before filling the holes with copper. Immersing these holes in copper will cover the walls of the previously drilled holes.

11、Outer Layer Imaging

We apply photoresist to the PCB panel. In this step (step 4), we apply another photoresist layer. However, this time the photoresist can only be applied on the outer layers because the PCB design requires imaging the outer layers of the panel. We start with the middle layer of the sterile room to prevent contaminants from sticking to the surface of the layer and then apply a layer of photoresist to the panel. Only the outer layers need to be coated with photoresist and imaged, and they will be plated the same way as the inner layers of the PCB in the previous step. However, while the process is the same, the outer layers are tinned to help protect the copper on the outer layers.

This process is just the opposite of that of the inner layer. Finally, an inspection of the outer panel is repeated to ensure that all unwanted photoresist was removed in the previous stage.

12、Outer Layer Etching

When the outer layer is etched the last time, the tin protection layer is used to help protect the copper during the etching process. Use the same copper solvent as before to remove excess unwanted copper. At the same time, the tin protects the valuable copper at this stage.

Conductive regions and connections are now correctly established.

13、Outer Layer AOI

Like the inner layer, the outer layer must also undergo automated optical inspection. Performing this optical inspection ensures that the layer meets the exact requirements of the design. It also verifies that the previous step removed all unused copper from the layers to create a functional PCB without unusable electrical connections.

14、Solder Mask Application

Before licking the solder mask onto the sides of the board, the panel needs to be thoroughly cleaned. After cleaning, the surface of each panel needs to be covered with epoxy solder mask ink. Next, the board is irradiated with UV light to indicate where the solder mask needs to be removed, and the covered parts that are not fully hardened will be removed.

After the fabricator removes the solder mask, finally, the board goes into an oven to cure the solder mask.

15、Surface Treatment

Enig: Electroless nickel immersion gold is one of today’s most popular and widely used circuit board finishes. ENIG consists of two coatings, 2-4 μ” Au, placed on 120-200 μ” Ni. The gold protects the nickel from corrosion, and the nickel protects the base metal plate, allowing circuits to be securely soldered to its surface.

IAg: Immersion Silver (IAg) is applied directly to the base metal of the PCB by chemical displacement. It is more affordable than ENIG and is RoHS-compliant. Typical thicknesses for immersion silver are 4-12u”. Because of how copper and silver interact, they will eventually diffuse into each other.

Immersion Tin: Immersion tin (ISn) is applied directly to the base metal of the PCB by chemical displacement. It’s a more affordable option than ENIG and Immersion Silver and is also RoHS compliant. Typical thicknesses for immersion tin are 20-50u”. Because of how tin and copper interact, they will eventually diffuse into each other.

Lead-Free Hasl: Due to concerns over the use of lead in manufacturing, non-toxic and more environmentally friendly types of PCB finishes are gaining popularity. Lead-free HAL finishes use tin or copper paired with nickel to form a protective coating. Lead-free HASL has the same advantages and disadvantages as HASL, except that it is RoHS compliant.

Hasl: Hot Air Solder Leveling, or HASL, is an affordable finishing option that utilizes tin/lead in creating a thin protective layer on the PCB. Hot air jets are used to remove excess lead or tin from the surface of the circuit board. HASL used to be the industry standard, but due to potential RoHS compliance issues, HASL’s popularity has declined.

Osp: PCB surface finish comparisons based on green appeal leave no doubts. Organic Solderability Preservatives (OSP) do not introduce toxins into the process. Instead, use organic compounds that naturally bond with copper, forming an organometallic layer that prevents corrosion.

Hard Gold: Among the most expensive PCB finishes, hard gold applications are durable and have a long shelf life. They are generally reserved for components that are expected to be used in high volumes, with normal thickness rates ranging from 30 μin gold over 100 μin nickel to 50 μin gold over 100 μin nickel. It is not commonly used for solder joints due to poor solderability. Hard gold is commonly used in edge connectors, battery contacts, and test boards.

 

17、Electrical Test

As a last resort, the fabricator conducts electrical tests on the PCB. Confirm the functionality of the PCB and its consistency with the original PCB design through automated procedures. In addition to basic electrical reliability testing, other advanced tests can be used to determine if a PCB is functioning properly.

18、Analyze

Now we come to the next step – Analysis: This requires the manufacturing engineer to confirm the shape and dimensions of the individually printed circuit boards cut from the building board. This information can usually be extracted from the Gerber file. The two ways to use it are using the router as the center of the V-shaped groove as the center. Both options above will allow the board to separate cleanly without cracking.

19、Quality and Appearance Inspection

After stripping the board for scribing, the PCB must undergo a final inspection before being packed and shipped. This final check verifies several vitals of the board construction:

•Is the hole size matched on all layers and meets design requirements?
•Whether the board size is consistent with the size in the design specification.
•Whether there is dust and debris on the circuit board that has not been cleaned.
•Whether the finished board has burrs or sharp edges.
•All boards that fail electrical reliability testing must be repaired and retested.

20、Packaging and Delivery

The final stage of PCB manufacturing is packaging and delivery. Packaging is usually chosen to achieve a seal around the printed circuit board to keep dust and other debris out. The sealed circuit boards are then placed into professional packaging to ensure they will not be damaged or crushed during shipping. In the end, they will deliver it perfectly to the customer.

As you can see, much-specialized work is manufacturing printed circuit boards. To ensure PCB fabrication meets your expectations of quality, performance, and durability, you must select a manufacturer with high expertise and adherence to a rigorous quality control process.
