InstaPCB vs JLCPCB

Side-by-side capability comparison for Adom's in-house InstaPCB fab + assembly line vs JLCPCB, the high-volume Chinese prototype house most engineers benchmark against.

InstaPCB is Adom's UV-fiber-laser fab + stencil-free solder-jet assembly line in Fort Worth, TX. Drone-delivered components from Mouser DFW (~40 min) keep the line stocked. Boards land in your cloud workcell within 4 hours of submitting gerbers.

The interactive comparison tab below covers every spec a customer or DFM tool needs at quote time — turnaround, MOQ, mechanical envelope, conductor specs, drilled features, solder mask + silkscreen, surface finish, stackup + impedance, and assembly DFM.

Where InstaPCB wins

• Turnaround — 4 hours fab + assembly vs JLCPCB's 3-5 day standard / 24-48 h express
• MOQ — 1 board vs JLCPCB's 5-board minimum
• Min trace width — 0.08 mm (3 mil) vs JLCPCB's 0.127 mm (5 mil) on 2-layer
• Min annular ring — 0.125 mm vs JLCPCB's 0.15 mm
• Min via drill — 0.20 mm on every layer count vs JLCPCB's 0.30 mm on 2L
• Trace-to-edge clearance — 0.05 mm vs JLCPCB's 0.30 mm (laser depanel is glass-clean)
• Min silkscreen text — 0.10 mm vs JLCPCB's 1.0 mm (laser etch resolves much finer than printed silk)
• Selective V-scoring — Adom-invented: any 2D curve with designer-placed trace bridges, replaces mousebites entirely
• Edge plating — free side-effect of the laser-cut + electroplate sequence; no add-on fee
• Native single-board ordering — depanel laser cuts the final outline as the last process step
• In-line per-net electrical test — every net probed before mask + silk

Where JLCPCB wins

• Layer count — 1-20 (32 advanced) vs InstaPCB's 1, 2, 4, 6
• Board thickness flexibility — 0.4 / 0.6 / 0.8 / 1.0 / 1.2 / 1.6 / 2.0 / 3.2 mm vs InstaPCB's 1.6 mm only
• Solder mask color — 7 colors vs InstaPCB's green only
• Surface finish options — HASL / ENIG / OSP / immersion silver / tin vs InstaPCB's bare-Cu / as-plated
• Copper weight options — 0.5 / 1 / 2 / 3 oz vs InstaPCB's 0.5 oz
• Impedance control — ±10% controlled-impedance certification (microstrip / coplanar / diff-pair) vs not offered on InstaPCB today
• Max aspect ratio — 10:1 vs InstaPCB's 8:1
• Max board size — 400 × 500 mm vs InstaPCB's 304.8 × 381 mm (12" × 15")
