CEM-1 PCB may be unfamiliar to many, but it is one of the most widely used substrates for single-sided printed circuit boards. Although considered a low-grade PCB material, its affordability and practicality make it a popular choice for applications where cost control is critical.
Technology is advancing rapidly, and electronic devices are becoming smaller and more complex. Despite this, CEM-1 PCBs remain relevant. The increased complexity and higher component count of modern devices often make single-sided CEM-1 PCBs a practical solution to reduce design costs while maintaining functionality. For many designers, using CEM-1 for single-layer PCBs is a strategic choice to optimize budget and production efficiency.
