The fiberglass weave is an essential factor in high-frequency PCB that causes a periodic inhomogeneity in a fiberglass PCB. It is a new aspect of PCB designing. This effect produces disintegrate signal transmission and very fast edge rates in high-frequency applications.
Besides, it creates different DK values in fiberglass substrates. That’s why PCB suffers from dispersion, propagation skew, resonances, etc.
You need to design the PCB routing and layer orientation properly so that you can avoid excessive signal skew. It is essential to use substrates having a lower refractive index to minimize the effect of PCB fiberglass weave.
How To Manufacture A Fiberglass PCB?
Fiberglass PC is the backbone of various electronic applications that include simple to complex designs. A well-manufactured fiberglass circuit board can ensure the proper electronic and mechanical properties of electronic goods.
That’s why you need to have a deep understanding of the manufacturing of this PCB. Its major steps are described below for your convenience.
The first and foremost step is designing the circuit board layout by using high-quality design software. The most recognized design software are Altium Designer, KiCad, Eagle, etc.
After completing the design, the designer converts it to a Gerber file. This file contains all necessary information about the PCB manufacturing process, like drilling, layer count, component mounting, etc.
When the designer checks the design, it is forwarded to the fabrication service provider. It is essential to run a DFM (Design For Manufacture) check before starting the fabrication.
Conversion Of File To Film
In this stage, the manufacturer takes some photographs to print the circuit board by using a plotter. This laser printer is effective for printing precisely and ensuring detailed images of the circuit board designs.
It is important to punch the registration film through all images. It ensures the proper alignment of films. Thus, a figure of the copper path is mapped.
Inner Layer Preparation
This step involves printing the figure onto a copper foil. The circuit board manufacturer creates a laminate by using substrate materials, which are fiberglass, epoxy resin, etc.
The preparation of the inner layer should be free from moisture and dust. That’s why the manufacturer keeps the copper-sided laminate in a decontaminated atmosphere. Usually, two layers of the PCB get prepared in this process. You need to handle many factors in the case of multilayer fiberglass PCBs.
In fiberglass circuit board fabrication, etching refers to the removal of unnecessary copper from the PCB surface. Here, the manufacturer covers the essential portions of the circuit board and places the PCB inside of the etching solvent.
This solution reduces all exposed copper. Then, you get a PCB having only the necessary copper substrates. You can check this video about etching: https://youtu.be/tWnfnt2rNO0
Alignment Of Layers
Layer alignment is a vital part of fiberglass circuit board manufacturing. An optical punch machine involves the registration holes to align the internal layers concerning the outer layers.
The next step is drilling the holes on the PCB. An X-ray locator determines the suitable locations for drilling. The manufacturer places some buffer materials into the lower part of drilled holes to avoid unwanted tearing of the circuit board.
To maintain the drilled-hole dimensions properly, the manufacturer applies laser technology in most cases. It is expensive, but effective for high-quality drilling.
Now, it is time to place the circuit board on a chemical solution multiple times. Thus, a thin layer of copper will be deposited on the circuit board. Then, these coppers go through the drilled holes.
This copper plating entirely covers the holes and creates a new layer on the PCB surface. The manufacturer incorporates an automatic system to handle this step.
Imaging The Outer Layer
After completing the copper plating, the next part is taking images of the outer layers. Here, photo resist is used to cover the board and UV rays are dropped upon it for imaging the external PCB layers.
Now, the manufacturing service provider removes the unwanted copper from the PCB surface in a similar way used before.
Use Of Solder Mask
In this part, the PCB receives the UV ray. This ray passes through a photo film of a solder mask. Here, the exposed portions get hard. The circuit board panel needs to be covered with epoxy solder mask ink before the application of the solder mask. During the cure of the solder mask, the manufacturer passes the circuit board into an oven.
The surface finish is a vital part of PCB manufacturing. It helps improve the solderability of the fiberglass circuit board. Usually, metallic and organic surface finishes are worthwhile for this PCB. The most used metallic surface finishes are
- ENIG (Electroless Nickel Immersion Gold)
- HASL (Hot Air Solder Leveling)
- ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold)
- Hard Gold
- Soft Gold
Each process offers particular benefits to the fiberglass circuit board. You need to choose a suitable metallic coating concerning your circuit board design and materials.
A reliable PCB manufacturer tests the circuit board for precautions. The flying probe test and the AOI tests are effective to check the functionality and designs of fiberglass PCBs.
The last but not the least step is V-scoring. It involves cutting the circuit board from the panel. The manufacturers usually apply routers and v-groove to conduct this task properly.
Do you still have any confusion about the performance of fiberglass PCB?
We don’t think so.
This circuit board handles mechanical and thermal pressures, along with improving the signal transmission system. That’s why you can experience high-quality features at affordable costs.
