A practical stackup path for interfaces that need predictable single-ended or differential impedance. Verified process window: Impedance tolerance: ±8%; Line / spacing example: Minimum 3 / 2.5 mil; Materials: TG135–TG180 FR-4 options Files for a useful review: Gerber or ODB++, drill files, stackup, fabrication drawing, quantity and target date. Published limits are drawn from JETFGO’s current capability chart. Final feasibility depends on the complete data package and engineering review.

Technical questions
Published limits are drawn from JETFGO’s current capability chart. Final feasibility depends on the complete data package and engineering review.
01Is 4-Layer Controlled-Impedance PCB automatically manufacturable?+
No. Published limits guide selection; final feasibility depends on the complete stackup, geometry, materials and acceptance criteria.
02Which files produce the fastest engineering answer?+
Gerber or ODB++, drill files, stackup, fabrication drawing, quantity and target date.
03Can JETFGO support prototype and repeat production?+
Yes. The same engineering record can support prototype review and a controlled transition to repeat production.
