Our company specializes in the R&D, prototipos, producción por lotes pequeños y medianos, and large-scale manufacturing of high-layer PCBs ranging from 16 a 36 capas. We focus on standardized production of 24-layer PCBs and have overcome six major industry challenges: multi-layer lamination misalignment, registration deviation, via copper cracking, dielectric inconsistency, impedance deviation, and board warpage.
The 24-layer PCB is a high-density interconnect (HDI) multilayer circuit board featuring high routing density, rendimiento eléctrico estable, strong EMI shielding, high integration capability, and strong computational load support. It is widely used as a core substrate in high-end industrial equipment, server computing systems, medical imaging devices, rail transit control systems, 5G communication base stations, y aeroespacial & Electrónica automotriz.
Unlike conventional low- and mid-layer PCBs, 24-layer PCBs undergo more than four sequential lamination cycles, blind and buried via alignment processes, inner-layer flow control design, and differential impedance management. They are designed to meet the requirements of miniaturization, alta integración, and high-frequency/high-speed circuit applications. We support customization with standard FR-4, high-TG materials, Rogers high-frequency laminates, and halogen-free substrates, ensuring long-term reliability under harsh industrial conditions.
