LED PCB
LED PCBs are specific types of printed circuit boards in lighting modules and applications, . Light emitting diodes (LEDs) are mounted to a PCB, allowing them to be controlled by various types of chips and switches.
LED PCB Materials
A variety of materials are available for designing LED circuit boards. Here are some of them so you can understand how they work and choose the one that works best for you.
1. Composite Epoxy Material (CEM)
Composite Epoxy Material (CEM) is an effective competitor to Flame Retardant Grade 4 (FR-4) material. It is a type of material that is most commonly used in LED PCB production. We will discuss the different classifications of Composite Epoxy Materials (CEM) here so that you will be able to understand how it is used for circuit board design.
Generally, Composite Epoxy Materials (CEM) are made by laminated cellulose and paper with woven glass fabric as a top layer. The first classification is CEM-1. The CEM-1 is the most preferred because it has the best flame retardant properties that allow for mass production of circuit boards. Moreover, the CEM-1 LED PCB can be manufactured on a budget. However, the production of single-sided circuit boards is limited by the inability to metallize through holes in the board.
Composite Epoxy Material (CEM) is not limited to the CEM-1 Material, which is the most commonly used. Another classification of Composite Epoxy Material (CEM) is the CEM-3 Material, which PCB consumers always choose for circuit board design. This PCB material is preferred for its better heat transfer properties. Thus, if you need to facilitate the dissipation and transfer of heat from your LED PCB, this PCB material is the one you need.
2. Flame Retardant Grade 4 (FR-4)
In addition to LED PCB materials, FR-4 is another type of LED PCB material. In comparison to the others, FR-4 has the least vulnerabilities, particularly when compared to CEM-1.
