A:Standard lead times are as follows:

● PCB Prototyping：3-5 working days (excluding logistics time)

● PCBA Samples：5-8 working days (including component procurement time)

● Expedited Service：Fastest 48-hour expedited prototyping (additional fee required)

Actual lead times may vary based on PCB complexity, layers, special processes, and component supply conditions. We will provide accurate lead time assessment within 24 hours of receiving files.

A:We provide flexible order quantity options to meet different client needs:

● PCB Prototyping：No minimum quantity, 1 piece minimum

● PCBA Samples：Typically 5 pieces minimum (negotiable for special packages or expensive ICs)

● Small Batch Production：50 pieces minimum

● Mass Production：1000+ pieces for volume discount pricing

For startup teams and R&D projects, we specially provide small batch trial production support to help clients reduce upfront investment risks.

A:We have established strict component quality assurance system:

● Supplier Audit：Only cooperate with original manufacturers or authorized distributors to ensure source traceability

● Incoming Inspection：Each batch of materials undergoes appearance, labeling, and electrical parameter testing

● Anti-Counterfeit Verification：Anti-counterfeit code verification and batch number checking for key ICs

● X-Ray Inspection：Internal structure inspection for BGA, QFN and other packages

● Traceability System：All materials have unique traceability codes for quick problem location

We promise: If product failure is caused by component quality issues from our procurement, we will bear all responsibility and losses.

A:Yes, we specially support small batch trial production services to help clients verify design and processes. Pricing is calculated based on:

● PCB Cost：Material type, layers, size, special processes (impedance control, thick copper, etc.)

● Component Cost：Actual procurement price of BOM list materials

● SMT Assembly Fee：Calculated by solder joint count or per board

● Engineering Fee：One-time fees for DFM analysis, stencil making, programming, debugging

● Testing Fee：Functional testing, programming, calibration, etc.

We provide transparent quotation with each cost item clearly listed. Small batch trial production typically costs 30%-50% more per unit than mass production, but unit price decreases significantly as production volume increases.

A:Yes, our professional DFM analysis can identify most common design defects:

● Manufacturability Issues：Minimum trace width/spacing violations, improper pad design, insufficient solder mask bridge, etc.

● Assembly Issues：Insufficient component spacing, improper thermal design, missing BGA escape vias, etc.

● Signal Integrity Issues：Impedance discontinuity, incomplete reference layers for critical signals, etc.

● Thermal Management Issues：Improper layout of high-heat components, poor heat dissipation paths, etc.

● Testability Issues：Insufficient test points, improper test point locations, etc.

We provide free DFM analysis report, detailing identified issues, risk levels and improvement suggestions. Through our DFM analysis, clients can avoid over 80% of design defects, significantly reducing trial-and-error costs.
