Blue PCB By Feature

Multilayer Blue PCB

The Multilayer PCB has numerous applications including computer systems, satellite systems, and medical equipment. It is becoming popular in the market because of its durability, flexibility, and compact size despite the lots of layers it has.

Rigid-Flex Blue PCB

The Rigid-Flex PCB is ideal for applications that frequently experience shocks and vibrations; it can tolerate many situations. Moreover, they are a great alternative if your application offers substantial space savings because of their versatility.

Rigid Blue PCB

The Rigid PCB has been recognized worldwide because of its thicker and fairly strong board. However, this sort of material board is prone to warping because of heat and chemicals. They are often deployed in heavy-duty applications.


The LED PCB’s primary advantage is its efficiency in terms of power consumption; thus, making it very popular among users since it can save them a huge amount of money. Also, integration of complex circuitry is not a problem in this type.

Double-Sided Blue PCB

The Double-Sided PCB is the perfect option if you have a lot of electrical components you want to incorporate into your board. Also, this could be the ideal type of Blue PCB to take if your application requires deploying a complex circuitry design.


The HDI PCB has become more progressive in the industry because of the numerous advantage it possesses. This is a suitable option for you if you want to enhance the signal integrity of your application with a very compact and sleek design.

Blue PCB By Surface Finish (5)

  • ENIG Blue PCB

    The ENIG PCB is the most common surface finish in the market because of its excellent flatness and smoothness that integrating components is made easier and simpler. It is highly durable and reliable.

  • HASL Blue PCB

    The HASL PCB can be lead-free; this makes it RoHS compliant. This is recognized to be the most economical and widely used finish among others. If you’re seeking to reduce costs, this finish is the perfect option to take.

  • Immersion Tin Blue PCB

    The Immersion Tin PCB is ideal for components that are small or BGA. This finish can be economical since it doesn’t use lead. However, once the copper is applied to the board, this can be prone to tarnishing.

  • OSP Blue PCB

    The OSP PCB is relatively inexpensive compared with other surface finishes. Its pads possess extreme flatness compared with the HASL finish. Also, it is known to be re-workable and it is easy to manufacture.

  • Immersion Silver Blue PCB

    The Immersion Silver PCB’s primary advantage is its capability to be re-worked; thus, it can save you a lot in the long run. However, it can be prone to tarnishing when exposed to air so it needs proper packaging.

Blue PCB By Layer (5)

  • 4-Layer PCB

    The 4-Layer PCB has exceptional thermal control; it has the capability to distribute the heat generated by the devices all-throughout the entire circuit board. It has enhanced signal routing compared with the 2-Layer.

  • 6-Layer Blue PCB

    The 6-Layer PCB possesses commendable electrical properties on it that make it preferable in high-speed designs. In comparison with the 4-Layer, it has increased signal and power integrity, and good routing ability.

  • 8-Layer Blue PCB

    The 8-Layer PCB can already be termed as a multilayer board. This type of board is ideal for complex devices since it possesses low electromagnetic interference. Also, this layered board has increased signal integrity.

  • 10-Layer Blue PCB

    The 10-Layer PCB is highly-preferred by consumers since it is way more durable than low-count layered boards. Moreover, this type of layered board is recognized to be efficient even at a relatively inexpensive cost.

  • 12-Layer Blue PCB

    The 12-Layer PCB is recognized to be more powerful compared to other low-count layer boards; thus, they are preferred in high-density assemblies. Due to its versatility, it is widely used in many electrical devices.

Advantages of Utilizing PCBTok’s Blue PCB

Among the perks a Blue PCB can provide are the following:

  • Contrast – It offers a good balance between the solder mask and silkscreen. This is ideal if your applications possess lots of part numbers.
  • Clarity – The dirt build-up can be easily spotted, and it is fairly easy to distinguish the metal from the board.
  • Aesthetics – In comparison with the green-colored board, it is way more pleasing to look at. Also, it can be easily repaired.

If you wish to know more about PCBTok’s Blue PCB capabilities, we are available around the clock to assist your queries.

Proper Guidelines in Integrating Blue PCB Components

Proper Guidelines in Integrating Blue PCB Components

Apart from choosing the right manufacturer to perfectly build your Blue PCB, it is also essential to have adequate knowledge in incorporating components on it.

These are the following factors you might want to consider in placing components:

  • Functionality – Calibrate each component before placing.
  • Placement – Determine the power, signal, and ground tracing before attaching the electrical components. This will reduce the risk of failure.
  • Categorization – Sort the components according to their usage; this will also aid in heating concerns along the way.

Just message us for the detailed guidelines; we are available 24/7.

Layers that Comprise the Blue PCB

There are several different layers that compose the Blue PCB; they are glued like sandwiches. Here are those layers:

  • FR4 – A base material that provides rigidity, thickness, and stability to the PCB.
  • Copper – This can be located on top of the FR4 and below the solder mask layer.
  • Solder Mask – Located at the top most part; this showcases the Blue PCB color.
  • Silkscreen – This is on top of the solder mask layer that contains letters, numbers, and words that act as an indicator and guideline for the assembler.

If you wish to have further knowledge concerning the common stack-up of PCBTok’s Blue PCB, you can just message us.
