SLP Manufacturing Capability

Confirm SLP Manufacturing Feasibility Before Production

JETFGO is a Shenzhen-based substrate-like PCB (SLP) manufacturer providing ultra-fine-line and high-density interconnect solutions for advanced electronic products. Substrate-like PCB technology bridges the capability gap between conventional HDI PCB and IC substrate technology. By using advanced processes such as mSAP and amSAP, SLP structures can achieve finer line and space, smaller laser microvias and higher routing density than conventional PCB designs. JETFGO supports any-layer SLP structures up to 16 layers, laser microvias from 50 μm and fine line / space from 30 / 30 μm, subject to engineering review and project requirements. Our SLP manufacturing solutions are suitable for mobile devices, wearable electronics, advanced semiconductor-related systems, AI and high-performance computing modules, optical communication equipment, IoT devices and other compact electronics requiring high interconnect density. From engineering review and stack-up evaluation to fabrication, inspection and production support, JETFGO helps customers evaluate whether SLP, advanced HDI or another PCB technology is the most manufacturable solution for the project.
