KB-6150 By Type

Single-Sided PCB

The single-sided KB-6150 printed circuit board is a great choice for any project that requires a relatively small PCB with a high level of flexibility.

Double-Sided PCB

A KB-6150 printed circuit board designed for applications where you need to be able to connect multiple components on both sides of the board.

4-Layer PCB

The 4-Layer KB-6150 printed circuit board allows your device to run more efficiently because it has four layers instead of lesser, as traditional PCBs do.

6-Layer PCB

Perfect for projects that require high quality components to function. Also great for making prototypes and testing new circuits before production.

8-Layer PCB

The 8-layer PCB is suitable for use in high-frequency applications and can be used as the basis for surface mount, flip chip and hybrid packages.

10-Layer PCB

Also a great option for those looking to prototype their next project. This is an affordable and versatile PCB, which can be used in many applications.

KB-6150 Technical Information

The KB-6150 printed circuit board is a high-quality, durable circuit board that has excellent dimensional stability and heat resistance, as well as excellent mechanical properties.

KB-6150 is a single-sided, double-sided, and multi-layer PCB that is made from pure copper or copper with tin or nickel plating.

The KB-6150 is IPC-4101D/21 specification is applicable, which means it can be used in a wide range of applications including medical, automotive, aerospace and industrial.

KB-6150 Technical Information
Flame-Resistant KB-6150

Flame-Resistant KB-6150

Flame-resistant KB-6150 printed circuit board is a type of flame-resistant board with the advantages of flame retardant, high thermal conductivity, low smoke generation and good insulation performance. It is mainly used in electronic equipment, instrumentation and other fields.

KB-6150 has excellent flame-retardant performance. At the same time, it has superior thermal conductivity and heat dissipation performance. This makes it ideal for use in areas where there is a high risk of fire or other forms of combustion, such as in electrical power stations and industrial facilities.

Dependable Dimensional Stability

The KB-6150 printed circuit board is an excellent choice for customers who are looking for dependable dimensional stability. While there are many factors that contribute to this characteristic, the most important is the epoxy resin used during fabrication.

In order to achieve dimensional stability, it is necessary for a KB-6150 PCB manufacturer to use an epoxy resin with high thermal and chemical resistance. This allows the board to maintain its properties even after being exposed to high temperatures or harsh chemicals. The KB-6150 uses epoxy resin that has been optimized for use in printed circuit boards.

KB-6150 PCB Fabrication

Excellent Heat and Moisture Resistance

KB-6150 printed circuit board is a high-quality PCB that has excellent heat and moisture resistance. This is an important characteristic for the circuit boards used in various applications, including those that are exposed to extreme temperatures or subjected to moisture conditions.

The unique molecular structure of the insulating material used in KB-6150 printed circuit board makes it resistant to heat and moisture. This means that the circuit boards can be used in harsh environments without suffering any damage.

Supreme Thickness Uniformity

The supreme thickness uniformity of the KB-6150  is an indication of how well the copper layers are evenly they’re applied. The more uniform the layer thickness, the better your product will be able to withstand wear and tear and still function properly.

KB-6150 from PCBTok is the best option for your next PCB project. It’s made using a proprietary method that allows for uniform thickness throughout the board, which means you won’t have to worry about warping or other issues caused by uneven layers.

KB-6150 and KB-6160 Variation

The KB-6150 and KB-6160 are variations of one another, but there are some key differences.

KB-6150 has excellent dimensional stability and heat resistance, as well as mechanical properties. However, this resin has a tendency to smear in high-speed drilling.

KB-6160 is also a variation of the KB-6150. It shares all of the same characteristics as its predecessor, but it has less resin smear in high-speed drilling and UV blocking, which makes it slightly more suitable for use with AOI machines than its predecessor.

KB-6150 is IPC-4101D/21 Applicable

IPC-4101D/21 is an IPC standard used to define the design, construction, and testing of electric motor controllers. The standard is maintained by the IPC.

The purpose of this standard is to provide requirements for the design, construction and testing of electric device that are suitable for use in electronic applications.

IPC-4101D/21 is intended to provide a uniform basis for specifying the base materials required in rigid and multilayer printed boards, especially KB-6150. The requirements are presented in tables of values or in general terms that can be applied to any type of material.

KB-6150 UL Certification E123995

The UL Certification E123995 is a standard for Metal clad industrial laminates for use in single layer printed wiring boards with copper on one or both sides furnished as sheets. This certification is the mark of a company that has met the highest standards of quality and safety.

This certification ensures that the products meet all industry requirements, including quality control and safety standards. The products are tested to ensure that they can withstand extreme temperatures, moisture, and pressure.

KB-6150 printed circuit boards meet this certification, and this means that they are safe to use in your electronics projects.
