PCB Film By Feature

Copper Clad Film

The Copper Clad Film we specifically integrate into your board is among the market’s most commonly used film types. It can be used in automotive, aerospace, and medical circuit board devices. However, we do not sell it as is; you’ll get this as a set to your PCB.

Plain Mylar Film

The Plain Mylar Film that we specifically integrate into your board is recognized to be tough; thus, it can be highly reliable. They have a rough surface that makes handling easy and good processability. But we do not sell it as is; you’ll get this as a set to your PCB.

Polyimide Film

The Polyimide Film that we expressly incorporate in your board is another popular film type due to its ability to retain its shape even when exposed to different and changing thermal conditions. However, we do not sell it as is; you’ll get this as a set to your PCB.

Protection Film

The Protection Film we expressly incorporate into your board is ideal for applications requiring an extra layer of shielding mechanism against high-temperature environments. But we do not sell it as is; you’ll get this as a set to your PCB.

PET Release Film

The PET Release Film that we specifically integrate into your board comes in different options; we have the transparent and blue ones. It has a High TG value that can tolerate up to 410°F. However, we do not sell it as is; you’ll get this as a set to your PCB.

Anti-Static Film

The Anti-Static Film that we specifically integrate into your board is ideal for applications that are prone to static-electrical charge since it can reduce its occurrences. It possesses acid resistance. But we do not sell it as is; you’ll get this as a set to your PCB.

What is a PCB Film?

One of the first phases in producing your PCB products is designing the circuit pattern of it. It can usually be found in your CAD files.

Straightforward, a PCB Film’s role is to wet or dry transfer your software-created printed circuit design into your bare board utilizing several approaches.

Given that this can be challenging and needs a high level of competence to execute well, we strongly advise choosing an experienced manufacturer.

Get in touch with us, and we’ll walk you step-by-step through the application process for a PCB Film.

What is a PCB Film?
Two Types of PCB Film: Dry and Wet

Two Types of PCB Film: Dry and Wet

As mentioned in the previous articles, we offer two approaches to integrating your PCB Film to the bare board; wet and dry.

  • Dry Film – It can be sub-categorized into two types; photopolymerization and photodecomposition. The dry photopolymerization films solidify when exposed to a specific wavelength of light, shifting from a water-soluble compound to one that is not. In contrast, the photodecomposition is the opposite.
  • Wet Film – It is a photosensitive liquid resist that often has a blue viscous liquid appearance. It utilizes tackifier resin to increase the resist’s overall acid and alkali tolerance.

Difference between the Wet and Dry Film

One crucial decision to incorporate your design into the chosen board is the method to take. Hence, we’d like to give their differences.

  • Dry Film – It has a straightforward process but can be a little expensive. However, the films’ protective coating diminishes circuit schematics’ precision, and after-pasting blemishes may result in circuit errors.
  • Wet Film – We suggest using this approach if your board has an uneven surface since it has higher precision. Also, it is relatively more affordable than dry film. However, the liquid waste it emits can harm the environment.

If you’re still confused about what method to take; kindly message us for further assistance.

PCB Film Fabrication

How does Dry Film Work?

Even though both of these approaches have one goal and have similarities in their usage, they differ in terms of their working application.

The first phase of integrating this film is printing your customized circuit design. Then, place it underneath the dry film with the CCL affixed.

After it, expose it to the UV machine. In the meantime, the coated dry film can be withdrawn while the dry film exposed by the circuit pattern hardens.

After the raw copper wire has been plated and etched and the required circuit traces have been obtained, the cured, solidified coating has been eliminated.

How does Wet Film Work?

In terms of their application process, they do not differ that much. However, it is evident that dry film has a more simplified approach.

We conduct a simple production process in a wet film; brush plating in which substrate pre-treatment is involved, and then dry screen printing.

After undergoing printing exposure, it will be subjected to the pre-baking phase, which will be put into an oven. Then, it will experience exposure.

Finally, it will be put into the developing phase, wherein the wet film is partially removed to obtain its desired pattern. Then, it goes through etching and stripping.

How to make PCB using Photoresist Dry Film?

The process of applying Photoresist Dry Film to your bare board is relatively simple; we’ll share with you the easiest way to perform it, even at home.

First, we recommend preparing the necessary materials for the procedure, including a laser printer, laminator, tape, film, adhesive, resist developer and stripper, glass sheets, yellow bug light, and a light-safe area. Then, create your desired circuitry pattern.

After that, print the artwork. Next, create the transparencies. Then, prepare the copper clads board by scrubbing it. However, we suggest lightly scouring it.

It was followed by laminating it, exposing, developing, etching, stripping, applying solder mask and silkscreen, solder paste stencil, and reflow soldering.

If you wish to have detailed information about this, feel free to call us for better assistance.
