Process Limit Notes for Double Sided FR4 PCB
Double sided FR4 PCB uses plated through holes to connect top and bottom copper layers. Drill size, annular ring, copper plating, and via clearance are reviewed during DFM preparation.
0.15 / 0.15mm is the standard reference for stable production. Smaller values or dense routing should be reviewed based on copper weight, solder mask bridge, and etching compensation.
Golden finger boards require additional review of bevel angle, edge connector tolerance, pad pitch, surface finish, and insertion durability requirements.
2-Layer FR4 PCB Design Capability Reference
The following values are reference ranges for quotation screening. Final manufacturability depends on copper weight, board thickness, via density, solder mask bridge, hole tolerance, and surface finish.
| Parameter | Standard Capability | Advanced / Review Required | Engineering Note |
|---|---|---|---|
| Min Trace / Space | 0.15 / 0.15 mm | Below 0.15 mm by review | Affected by copper weight and etching compensation. |
| Mechanical Drill | 0.30 mm reference | Smaller holes by review | Finished hole tolerance and plating reliability must be checked. |
| Board Thickness | 0.6 - 2.4 mm common range | 0.4 - 3.2 mm by review | Thin and thick boards require additional process confirmation. |
| Copper Weight | 1oz standard | 2oz / 3oz by design review | Heavy copper affects trace spacing and etching tolerance. |
| Surface Finish | HASL / OSP | ENIG / golden finger | ENIG is preferred for flat SMT pads or connector applications. |
| Panelization | Individual / V-Cut / tab routing | Custom mould forming by review | Panel design affects SMT efficiency, yield, and shipment safety. |
2-Layer FR4 PCB Production from Gerber and Drill Files.
Double sided FR4 production requires controlled laminate selection, accurate drilling, reliable through-hole plating, top-bottom registration, solder mask alignment, surface finish stability, electrical net testing, and final visual inspection.
YC PCB supports standard double sided FR4 PCB, industrial control boards, golden finger boards, LED FR4 control boards, communication interface boards, and double sided PCBA production.
General Capability Range
Thickness selection depends on copper weight, via diameter, finished hole tolerance, and mechanical strength requirements. Consult engineering for specifications below 0.6mm or above 2.4mm.

Gerber-Based Pricing for Double Sided FR4 PCB
Double sided FR4 PCB pricing is calculated from the Gerber file, drill file, board size, surface finish, copper weight, panel utilization, production quantity, and assembly requirement.
The following factors usually have the strongest impact on the final quotation.
The strongest pricing driver. Better panel utilization reduces material waste and unit cost.
Higher drill count increases drilling time, plating load, and inspection complexity.
HASL is the baseline cost option. ENIG is selected when pad flatness, storage stability, or golden finger requirements are important.
1oz is the common baseline. 2oz and 3oz copper increase material cost and etching control requirements.
Prototype, pilot run, and batch production are quoted separately. Volume pricing improves after panel and process conditions are stable.
