Before fabrication begins, LHD TECH engineer analyze your file for manufacturability, compliance with the chosen stackup, drill chart limitation, copper balancing, and signal integrity. They offer suggestion to avoid common design error, such as solder mask slivers, incorrect annular ring sizes, or non-standard via diameters.
Raw laminate sheets (FR4, Rogers, polyimide, etc.) are cut to precise dimensions, with careful identification and traceability (barcodes/lot tracking) for every panel—critical for ensuring RoHS, UL, or ISO compliance in regulated market.
Laser Direct Imaging (LDI) is follow by etching to form traces. Each layers is checking with AOI to detect shorts, opens, under-etch, or over-etch before proceeding to lamination. This is particularly important for complex HDI and impedance-controlled PCBs.
Inner layers and PP are heated and pressed together, forming a solid PCB stack. For rigid-flex and special high-layer-count design, LHDPCB uses advance presses for accurate thickness and no layer shift.
Precision equipment drills for through-holes, blind/buried vias, and laser-drilled microvias. Back drilling is used for removing stubbed vias in high-speed backplanes. Copper is deposited electrochemically for robust, low-resistance connections.
Outer pattern is created—matching the inner layer process—follow by selective copper/nickel/gold/OSP/Immersion finish deposition as specified.
Liquid Photo Imageable (LPI) soldermask is applied, imaged, and cured. Silkscreen adds ident, polarity marks, and branding—customizable in multiple color for easy assembly and service.
A range of finishes (ENIG, HASL, Immersion Silver/Tin, ENEPIG, Gold Fingers) is available, selected based on your assembly requirement and environmental durability need.
Boards are routed or V-scored for panelization. LHDPCB supports custom board outline, slot, cutout, and scoring for easy final separation.
100% electrical test (flying probe or bed-of-nail) guarantee every net is correctly connect. Visual, AOI, and—for some projects—X-ray and micro-section inspection assure total defect elimination.
Boards are cleaned, dried, and sealed in anti-static packaging, with full barcoding and documentation for traceability. LHDPCB offer vacuum packing or moisture barrier solution on request.
