How Will You Manufacture A USB Flash Drive PCB?

Here is the manufacturing process of a USB flash drive PCB:

  • Design

In this stage, the designer will use PCB design software to design a compatible USB flash drive PCB.

Examples of software they might use include KiCad, Altium Designer, Eagle, etc.

After approval, the designer sends the design to manufacturers as a Gerber file since it is a standard.

  • File to film

The manufacturers apply plotters to form photo films of the USB flash drive PCB since they are accurate and offer more detailed films.

This results in the production of plastic sheets with blank ink to represent the photo negative of the circuit board.

The clear internal areas do not have conductive materials while blank ink represents the presence of conductive copper within the inner layer.

However, the outer layers will apply the opposite pattern as you will etch out the black areas.

This process happens for all layers that you will use within a USB flash drive PCB.

  • Inner layer printing

This stage is where you make the actual USB flash drive PCB and the whole process happens in a dust-free environment.

Also, you will pre-bond a copper layer on the sides of the board.

Clean panels receive photo resist which hardens in the presence of UV light to ensure an accurate match from photo films to photoresists.

Afterward, you use alkaline solutions to wash the board to eliminate unhardened photoresists.

Then you will dry the board.

  • Eliminating surplus copper

This entails using strong chemical solutions to remove excess copper while desired copper will remain intact below the hardened photoresist.

The next stage entails removing the hardened resist using a solvent to reveal the copper below.

  • Layer alignment

In this stage, you use registration holes to align the internal layers to the external layers.

Technicians use an optical punch machine that accurately punches holes to the registration holes.

Besides, you will conduct an automatic optical inspection to ensure there are no defects.

  • Bonding

In this stage, you will bond all layers together by conducting layer-up and bonding processes.

Bonding happens on steel tables composed of metallic clamps to secure the layers hence inhibiting shifting when aligning.

  • Drilling

This entails using drills to bore holes with diameters of up to 100 microns.

Also, you use x-ray locators to precisely identify the area you are to drill.

The holes are where you will place vias and mechanical mountings.

  • Plating

This involves fusing layers by employing chemical depositions.

The chemical paths deposit thin copper on the panel which then fills the holes you drilled earlier.

  • Imaging the outer layer

This entails imaging external panel layers with photoresist opposite to the process you did on the inner layers.

  • Plating

This entails electroplating the board with a thin copper layer.

  • Etching

Tin will protect the copper you want during this phase as you eliminate surplus copper using chemical solutions.

  • Application of solder mask

Here, you will clean and cover the panel with epoxy ink before passing the board in UV light to remove unhardened parts.

  • Surface finish

This entails adding a chemical plate to the panel to give it additional solder-ability.

Besides, there are different surface finish you can apply and this depends on several factors.

  • Silkscreen

This entails applying inkjet markings on the surface of the board with important information regarding the circuit board.

After that, you will coat and cure the PCB.

  • Electrical test

This ensures that the board is fully functional and that it meets the original design.

  • Profiling

This entails cutting the board from the original panel to size.
