Detailed Analysis

1. Company Strength — 20 Points

Basis

• Factory location: Guangdong, China
• Factory area: 3,800+㎡
• Employees: 50+ staff
• Verified supplier / factory inspection status: True
• Product scope includes customized PCB, PCBA board manufacture, SMT circuit boards, and PCB assembly services.

Elaboration

The supplier has a physical production base of over 3,800㎡ and more than 50 employees, which suggests it has an established operational setup rather than functioning purely as a trading entity. The combination of PCB customization, PCBA manufacturing, SMT circuit board production, and one-stop PCBA service indicates manufacturing coverage across multiple PCB-related processes. However, the scale is not large based on the provided factory area and employee count. The available data supports a small-to-medium production profile with verified supplier status, but does not provide details on production lines, monthly capacity, equipment lists, engineering team size, or factory certifications such as ISO or IPC-related certifications.

Scoring Rationale

The supplier demonstrates basic-to-moderate manufacturing strength through its verified supplier status, physical factory area, and 50+ staff size. This is stronger than a low-transparency supplier with no factory information, but it does not reach the level of a large-scale stable supply chain because the factory area and workforce are relatively moderate and no detailed production capacity or formal factory certification data is provided. Therefore, the company is best assessed as a medium-small but operationally established factory.

Final Score

15 / 20

2. Platform & Compliance Credibility — 20 Points

Basis

• Gold Supplier: True
• Gold Supplier duration: 8 years
• Trade Assurance: True
• Verified supplier: True
• Certification / industry tags: Finished product inspection, ODM service available, Minor customization, Full customization

Elaboration

The supplier has a relatively strong platform credibility profile. An 8-year Gold Supplier history indicates a long-term presence on the platform. Trade Assurance provides an additional transactional protection mechanism for buyers. The verified supplier status further strengthens credibility from a platform compliance perspective. The listed service and quality tags are also relatively complete, including Finished Product Inspection and customization-related capabilities.

Scoring Rationale

The supplier meets several important platform trust indicators: long Gold Supplier history, Trade Assurance support, supplier verification, and multiple certification/service tags. These data points collectively support a high level of platform credibility. The only limitation is that the provided information does not include detailed third-party audit reports, specific compliance certificates, or internationally recognized quality system certifications. Still, based strictly on the available -related data, the supplier has a strong and credible platform profile.

Final Score

19 / 20

3. Business Performance — 20 Points

Basis

• Orders in the past six months: 80+
• Transaction value in the past six months: CN¥2.6M+
• Store rating: 5.0
• Number of reviews: 3

Elaboration

The supplier has recorded more than 80 orders and over CN¥2.6M in transaction value during the past six months. This indicates active commercial performance and a meaningful level of recent buyer engagement. The 5.0 store rating is positive; however, the number of reviews is only 3, which limits the statistical reliability of the rating. A high score based only on a 5.0 rating would be overstated because the feedback sample size is small.

Scoring Rationale

The order volume and transaction amount suggest stable recent business activity, especially for customized PCB/PCBA products where order values can vary significantly depending on specifications. However, the very limited review count reduces the strength of commercial validation from customer feedback. The supplier therefore demonstrates solid transactional performance, but not enough publicly visible buyer feedback to be rated at the highest level.

Final Score

16 / 20

4. Service Capability — 10 Points

Basis

• Communication response time: ≤3h
• Full Customization: Available
• Minor Customization: Available
• ODM service: Available

Elaboration

The supplier supports Full Customization, Minor Customization, and ODM service, which is important for PCB and PCBA procurement where buyers often require project-specific layouts, assembly requirements, BOM matching, or customized board functions. The response time of ≤3 hours is acceptable and indicates reasonable communication efficiency. However, it does not meet the strongest benchmark of ≤1 hour response time.

Scoring Rationale

The supplier has strong customization-related service tags, which is highly relevant for PCB/PCBA sourcing. The response time is not the fastest but remains commercially acceptable. Because the data confirms customization capability but does not show ultra-fast response performance or additional service metrics such as engineering support speed, sample lead time, or after-sales handling, the supplier is rated in the upper-middle range for service capability.

Final Score

8 / 10

5. Delivery Performance — 10 Points

Basis

• On-time shipment rate: 97.5%

Elaboration

The supplier’s on-time shipment rate of 97.5% is strong and exceeds the 90% threshold for high delivery performance. This indicates that, based on the available platform data, the supplier has been able to fulfill shipments reliably within expected timelines.

Scoring Rationale

A 97.5% on-time shipment rate falls clearly within the top scoring range. For customized PCB/PCBA products, delivery reliability is particularly important because delays can affect downstream electronics assembly, testing, and product launch schedules. Since the provided data shows a strong on-time shipment rate and no negative delivery indicators, the supplier deserves a high score in this dimension.

Final Score

10 / 10

6. Quality & Customer Feedback — 20 Points

Basis

• Store rating: 5.0
• Number of reviews: 3
• Finished Product Inspection: Available
• Verified supplier / factory inspection status: True
• Trade Assurance: True

Elaboration

The supplier has a 5.0 store rating, which is positive, and it lists Finished Product Inspection as an available quality-related tag. Verified supplier status and Trade Assurance also provide additional confidence from a platform and transaction protection perspective. However, the quality feedback base is limited because only 3 reviews are available. The data does not include defect rate, return rate, detailed inspection standards, test procedures, quality certificates, or customer case references.

Scoring Rationale

The supplier has several positive quality indicators, including Finished Product Inspection, verified supplier status, and a perfect store rating. However, the small review count makes it difficult to fully validate consistent quality performance across a broad buyer base. For PCB/PCBA procurement, technical quality assurance is critical, and the absence of detailed certification or inspection-process data prevents a top-tier score. The supplier is therefore assessed as having good basic quality assurance visibility, but further buyer-side validation is recommended.

Final Score

17 / 20
