Long PCB Products Without Compromise

Any PCB that is longer than 12 inches, or 30.48 millimeters in metric units, is considered to be long.

There are numerous applications where a plus-size board like this might be useful.

This kind of board is customized due to its exceptional specification in length.

Our company follows RoHS compliance and lead-free manufacturing of Long PCBs.

In any case you want one, please contact us, PCBTok.

Long PCB By Feature

LED Strip Long PCB

The LED Strip PCB is used extensively in commercial and home settings, so it’s no wonder we mass produce it.

Long Multilayer PCB

Multilayer PCBs can occasionally be found in extra-long sizes. Example: used in power applications that are related to lighting areas.

Long LED PCB

Long LED PCB can be found in commercial buildings like stadiums, train stations, and malls. They come with controllers.

Long FR4 PCB

Long FR4 PCB may optionally be low in DK. The majority of these can use of Rogers FR4 premium laminates.

Flexible Long PCB

For your long-sized Flex PCBs, fine polyimide material is required. If you use flex, heat-resistance would be an added benefit.

Long Aluminium Substrate PCB

Even though the majority of the PCBs we create are standard sizes, aluminum or AlN PCBs can be modified to be longer.

Explain What is a Long PCB

Essentially, some customers would request customized-size PCBs such as the these.

The Long PCB exceeds the usual diameters of PCB standard sizes. Standard PCB sizes are as follows:

  • 12 x 18 inches / 450 x 300 mm
  • 18 x 24 inches / 455 x 610 mm
  • 24 x 9 inches / 609.6 x 228.6 mm
  • 12 x 9 inches / 450 x 228.6 mm

Anything that is longer and larger is a custom-made board called a Long PCB or Large PCB. A good manufacturer can make up to 59 inches (1498.6 mm) of Long PCB.

There are also thick PCBs and Heavy Copper PCBs available in the market.

Long PCB Applications

Long PCB Applications

A long-sized board is suitable for the following applications:

  • Aluminum boards are commonly employed in lighting systems.
  • Large LED panels, for instance, can be used for skylights, office lighting, home lighting, outdoor lighting, and photography.
  • Electrical panels, backplanes, support for LED lighting, power control panels, substation power panels, low and high voltage for electrical distribution are all examples of power applications.
  • The most common example of this type of board is LED strip lighting. Given that LEDs are regarded for being ecologically safe, it is already a common sight.

Long PCB Features

The qualities of this kind of board depend on two elements: the material utilized and the intended application.

  • Features for utilization purposes include high voltage, high current, and flame-retardant qualities (94 V-0 rated by UL).
  • The PCB Substrate will determine the type of material used.
  • You should have options for cutting-edge materials like Rogers, Taconic, Arlon, and Bergquist materials from a capable manufacturer.
  • FR4 or Fiberglass Epoxy-Resin material with a normal, medium, or high Tg is typically used for long-sized circuit boards.

Long PCB Fabrication

Long PCB Benefits

There are benefits in using long-sized boards over standardized ones, such as:

  • Comprehensive coverage area for lighting
  • Efficient power distribution, especially for boards with High Tg material
  • Longevity of the components attached to the board
  • Although relegated to specific places only, the installation takes a shorter time compared to installing multiple, smaller boards
  • Quicker to replace if breakdowns occur, as it is one piece only

These are only a few general benefits. Overall, the customer’s preference will determine the benefits.

Long PCB Limitations

The limitations of this type of board depends on the materials the circuit board is made of. There are many different types of PCB materials.

  • Copper-clad (FR4, FR2, FR1, FR5), ceramic, PTFE, glass, and even transparent materials found in Rigid-type, Long PCBs.
  • Rigid-Flex boards that are flexible are much more advantageous in miniature designs and machinery with bending sections.
  • In this dimension, you bypass the limitations Rigid PCBs impose on the design.
  • Low layer counts will limit your ability to execute at a high rate of speed if you use HDI type of boards.

  • “In order to have a look at my PCB Gerber file, I called PCBTok. They promptly responded and gave me a price. They provided sound pricing and advice. We are currently really pleased with the outcomes. If you need customized circuit boards and large-scale orders, I would heartily suggest this PCB source. I chose to give them a try after reading positive reviews. It is worthwhile! They did a fantastic job, and I wholeheartedly suggest them to others.”

    Arthur Atkinson, Commodity Manager from Wolverhamptom, UK
  • “Other businesses fall short of PCBTok in quality. The best part is that they offer the lowest pricing of any business I’ve ever tried for a high-quality item. Fast and excellent, especially for prototyping. I will most certainly be a repeat buyer. They were kind and conscious of the need to respect customers. They attempt to provide prompt service and I believe they have adequate personnel. They have been my constant for the past two years.”

    Daavid Kotnik, PCB Engineer from Ljubljana, Slovenia
  • “I adore the products and services offered by the PCBTok firm. They are constantly so meticulous. I’ve visited online PCB businesses. Without a doubt, the greatest, especially considering the cost. The service is excellent, and there is little any wait. Although speaking English is not their first language, they always give it their all. They really want to comprehend your orders. I would suggest this store to anyone looking to purchase circuit boards.”

    Samson Juris, Supplies Manager from Riga, Latvia
How is a Long PCB Manufactured?

The following steps are taken in the manufacturing of long boards based on the unique needs of the customer:

  • Customers indicate the precise size dimensions and preferred core thickness.
  • Usually, the same method used to create normal circuit boards is used to create these specifically sized circuit boards.
  • Epoxy resin is impregnated into bare boards, which are made of fiberglass. In order to create electronic routes, this makes the board electronically conductive.
  • The board’s components, including ICs and microcontrollers, use the routes. Less PCB connectors are present on long boards.
