ME-PCB specializes in cutting-edge LDI PCB manufacturing, revolutionizing traditional circuit board production. Laser Direct Imaging (LDI) replaces outdated phototool methods by using high-accuracy lasers to directly expose circuit patterns onto photosensitive resist. This eliminates alignment errors and distortion inherent in contact photolithography, achieving exceptional precision circuit boards with line/space resolutions down to 25µm/25µm (and below for HDI).

Our LDI process is engineered for high-density interconnect (HDI) PCB fabrication, supporting complex multilayer designs (up to 32+ layers) with microvias, blind/buried vias, and intricate routing essential for miniaturized electronics. The technology ensures perfect layer-to-layer registration (±25µm), critical for advanced BGA, QFN, and chip-scale packages. We use industry-leading LDI equipment compatible with FR-4, high-frequency laminates (Rogers, Taconic), polyimide, and heavy copper substrates.

Key advantages include rapid PCB prototyping acceleration – design changes are implemented digitally without physical tooling delays, slashing lead times. LDI eliminates phototool wear, scratches, and environmental variations, guaranteeing consistent quality in both prototyping and volume production. This is vital for impedance-controlled boards (>5GHz), RF/microwave applications, and mission-critical systems where signal integrity is paramount. The process significantly reduces defects like shorts, opens, and etching undercuts, enhancing yield and reliability. ME-PCB combines LDI with stringent ISO-certified quality control (including AOI, flying probe testing, impedance testing) to deliver boards that meet IPC Class 2/3 standards. Whether you need complex high-density interconnect PCB designs for wearables, high-reliability boards for aerospace, or high-speed digital PCBs, our LDI capabilities provide unmatched accuracy, repeatability, and faster time-to-market.
