Domande tecniche
I limiti pubblicati derivano dall’attuale tabella capacità JETFGO; la fattibilità finale richiede i dati completi.
01Is ±8% impedance tolerance guaranteed for every 4-layer PCB?+
No. ±8% is a published capability reference for this solution. Final feasibility depends on the complete stack-up, materials, copper thickness, trace geometry, target impedance and other project requirements confirmed during engineering review.
02Which files help JETFGO review a 4-layer controlled impedance PCB fastest?+
Send Gerber or ODB++, drill files, proposed stack-up, fabrication drawing, quantity, target delivery date and an impedance requirement table showing target values, tolerances, routing layers and reference planes.
03Can JETFGO support prototypes and repeat production for controlled impedance PCBs?+
Yes. Once the stack-up, materials and impedance requirements are confirmed, the approved engineering record can support prototype validation and repeat production under the same manufacturing conditions.
04What information is required for controlled impedance PCB manufacturing?+
For each controlled signal class, provide the target impedance, tolerance, routing layer and reference plane. The proposed stack-up, board thickness, copper requirements and material preference should also be included when available.
05Can a 4-layer PCB support both single-ended and differential impedance?+
Yes, when the stack-up, reference planes, dielectric structure and trace geometry are designed appropriately. Final manufacturability is confirmed after reviewing the complete PCB data and impedance requirements.
06Why is the reference plane important for controlled impedance?+
A continuous reference plane provides a defined return path and forms part of the transmission-line geometry that determines impedance. Plane gaps or changes can create impedance discontinuities and affect signal integrity.
