Free PCB DFA Check by NextPCB | Avoid Costly Assembly Errors

Why DFA Check Matters

Our DFA check service helps identify potential issues before production, saving you time, money, and frustration.

Prevent Production Bottlenecks

Identify and resolve potential manufacturing issues before they cause delays in your production timeline.

Reduce Production Costs

Fixing issues before production starts is significantly less expensive than making changes during or after manufacturing.

Optimize Batch Production

Ensure your designs are optimized for efficient manufacturing, resulting in higher quality products and faster delivery.

DFA Checklist

Our comprehensive DFA check covers these critical aspects of your PCBA design.

Production Process	Issue Description	Severity
Production process	Check if the Gerber files are complete, including all layers and drill files	High
Production process	Verify PCB silk layer has all component reference designators with correct orientation	High
Customer document confirm	Check if documentation includes necessary information (position, x/y coordinates, rotation angle, orientation)	High
Customer document confirm	Verify BOM for part number and quantity matching, component type and value description consistency, and proper reference designators	High
PCB	For components smaller than 0402 or with pitch less than 0.5mm, PCB surface treatment must use ENIG to avoid solder paste defects and inconsistent size issues	High
	For dense QFP components (pin pitch < 0.5mm) or BGA with ball pitch < 1.27mm, avoid HASL surface treatment to prevent uneven surface affecting soldering	High
	For BGAs with solder pad diameter < 10mil (0.25mm), PCB surface treatment should not use HASL (with or without lead), use ENIG instead	High
	Verify Gerber parameters consistency across systems: material, Tg value, board thickness, surface finish, stack-up, solder mask color, silkscreen color, copper weight, and impedance control requirements	High
	Check if Gerber has thermal relief pads. ICs should use thermal relief pads, while other components may use solid pads or thermal relief pads depending on size	High
	PCB copper should maintain at least 0.4mm distance from edges (V-cut ≥ 0.4mm; routing board ≥ 0.2mm) to prevent copper exposure or line damage	Medium
	Verify component package compatibility with solder paste design	High
	Check if through-hole dimensions are appropriate. For selective wave soldering components, ensure diameter is at least 0.3mm larger than component lead diameter	High
PCB	For asymmetrical connectors/sockets, verify silkscreen indicates pin 1 or orientation	High
PCB	Check if silkscreen indicates ON position for switches (or pin positions)	High

What Our Customers Say

Hear from engineers who have used our DFA check service.

"The DFA check service saved us from a costly manufacturing error. Their team identified several critical issues with our BGA footprints that would have caused significant rework. The report was detailed and included practical suggestions for fixes."

Michael Chen

Senior Hardware Engineer, TechInnovate

"As a startup with limited resources, NextPCB's free DFA check has been invaluable. They caught several issues with our surface finish selection that would have caused reliability problems in our IoT devices. Their turnaround time was impressive too - we got our report in just 6 hours!"

Sarah Johnson

CTO, SmartSense Solutions

"We've been using NextPCB's DFA check service for all our new designs. Their attention to detail is exceptional - they identified inconsistencies in our BOM that we had missed during our internal review. This service has become an essential part of our design validation process."

David Rodriguez

PCB Design Manager, ElectroSystems Inc.
