Stack-up & Impedance
Controlled impedance, dielectric thickness and copper balance should be confirmed before production release.
Lead Time
Reference delivery planning for prototype and small-batch PCB projects.
Quick-turn work is possible for many standard PCB projects, while HDI, high-speed, special materials, heavy copper and larger quantities need confirmed production planning.
Reference Schedule
Typical lead-time ranges before final engineering confirmation.
Standard prototypeCommon 2L-4L PCB: normally 3-7 working days after files are confirmed
Quick-turn prototypeSelected simple PCB projects can be reviewed for 24-72 hour production options
Multilayer PCB6L and above: usually 5-12 working days depending on stack-up, copper, testing and quantity
HDI / blind viaNormally project dependent because laser drilling, lamination cycles and inspection requirements affect schedule
High-speed / RF materialLead time depends strongly on material stock, stack-up approval and impedance requirements
Low-volume productionPilot and small-batch orders are scheduled according to quantity, repeat status and inspection requirements
Detailed Lead-Time Guide
More specific planning ranges for common PCB project types.
1L-2L standard PCB2-5 working days for many prototype requirements; urgent options can be checked after file review
4L standard PCB3-7 working days depending on stack-up, surface finish, electrical test and production load
6L-8L multilayer5-9 working days typical after stack-up confirmation and material availability check
10L+ multilayer7-15 working days or project dependent, especially for impedance, back drilling or special materials
HDI PCB7-18 working days depending on lamination cycles, laser drilling, microvia structure and inspection requirements
Rigid-flex / flex PCB10-20 working days typical; depends on material, stiffener, coverlay, bending requirement and test method
High-frequency PCB7-15 working days when material is available; longer if special laminate must be sourced
Heavy copper PCB7-15 working days or project dependent according to copper thickness, spacing, etching and plating difficulty
Low-volume repeat orderCan usually be planned faster than a new project when files, stack-up and inspection standard are unchanged
Report / document needsFAI, impedance report, microsection, CoC, material certificate or custom inspection data should be requested before release
All lead times are reference ranges. Final delivery depends on engineering confirmation, payment/order release timing, material stock, production load, quantity, testing and shipping method.
What Affects Delivery
Most delays can be reduced by confirming the right details early.
Material Availability
Special high Tg, low-loss, RF and flexible materials may need stock checking before final lead time is promised.
Process Complexity
HDI, back drilling, via plugging, heavy copper, special surface finish and tight tolerances can add process time.
Testing Requirements
Impedance test, microsection, dimensional report, FAI and additional outgoing inspection should be planned in advance.
