1. Capacity Assessment: 5 Core Metrics

Capacity is not a single number, but a comprehensive manifestation of multi-dimensional capabilities.

1. Design capacity vs actual capacity

The design capacity is the theoretical maximum, and the actual capacity needs to consider equipment utilization, personnel scheduling and material supply. When evaluating, factories should be asked to provide actual shipments for the past 12 months and compare capacity fluctuations in the off-peak season.

        📊Qtenboard reference data: Annual production capacity 500,000 units, daily production 200 units; 8 fully automatic production lines, the production line utilization rate has been maintained for a long time. 85%–92%The peak season can be increased to more than 95% through scheduling adjustment.
    

2. Size segment and product combination

Different sizes (55 "/65"/75 "/86"/98 "/110") vary greatly in production line occupancy time and material requirements. It is necessary to know the monthly capacity of each size segment of the factory, as well as the capacity allocation ratio of standard products and fixed products.

        📊Qtenboard reference data: Coverage 32″–110″ Full size, of which 65 ″-86 ″ is the main size segment, with flexible monthly capacity allocation; 7:3Independent OEM production lines can be produced in parallel.
    

3. Degree of automation and production line flexibility

The automation level of SMT, AOI, bonding, assembly and other links directly affects the efficiency and quality consistency. The ability to quickly change models (e. g., from 65 ″ to 75 ″) determines the flexibility of the plant to respond to multi-species orders.

4. Good rate and first pass rate

SMT defective rate (ppm), the whole machine pass rate (FPY), aging test abnormal rate is the key to measure the stability of the process. Ask the factory to provide data for the past 6 months and understand the processing process of defective products.

交互式白板高温老化测试车间 — Multiple whiteboards are tested side by side for 48 hours high temperature aging

        📊Qtenboard reference data: One-time pass rate of the whole machine ≥97%; SMT defect rate ＜300 ppmAbnormal rate of 48 hours high temperature aging test ＜1.5%(Abnormal products still need to pass the full inspection after repair).
    

5. Capacity expansion plan

Understand the plant's new production line commissioning, automation upgrades and personnel recruitment plans in the next 12-24 months to determine whether it has the ability to cooperate for a long time.

        📊Qtenboard reference data: It is planned to add two fully automatic production lines in 2027 and introduce a AI vision inspection system to further improve yield and efficiency.
    

2. delivery assessment: 5 quantitative indicators

The ability to deliver determines the success or failure of the project, and these five indicators must be quantified.

1. Standard delivery vs emergency order response

Standard delivery time (from order to shipment) is the normal capacity, and the response speed of emergency orders reflects the scheduling flexibility of the factory.

        📊Qtenboard reference data: Standard Delivery Period 15-20 days(bulk orders); urgent orders (≤ 50 units) can be shortened 7-10 daysThe expedited rate is transparent.
    

2. Order Fulfillment Rate

The proportion of orders delivered on time, and the average number of days late for late orders, are hard measures of delivery reliability.

        📊Qtenboard reference data: Past 12 Months Order Fulfillment Rate 98.7%, average delay of delayed orders 2.3 days(mainly due to changes in shipping schedule or customer).
    

3. Bulk order vs small batch customization

Can the factory efficiently handle large orders and small and medium batch customization at the same time? Is it equipped with "flexible production" capability?

        📊Qtenboard reference data: Batch orders (more than 100 sets) with stable delivery period; small batch customization (10-50 sets) passed Independent OEM production lineParallel production, not crowding out the main production line, delivery time is only extended. 3-5 days。
    

4. Logistics and warehousing capacity

Own warehouse area, inventory turnover, logistics partners, packaging standards, etc., directly affect delivery efficiency and product integrity.

自动化仓储与成品物流中心 — Automated warehousing and finished goods logistics center

        📊Qtenboard reference data: Own warehouse area 10,000+ ㎡, inventory turnover of about 6 times/year; cooperation with DHL, FedEx, Maersk and other head logistics; packaging through ISTA drop testSupport shipping and air transport.
    

5. After-sales and spare parts support

Spare parts inventory (motherboard, touch module, panel, etc.), after-sales response time and maintenance cycle, is the guarantee of long-term cooperation.

        📊Qtenboard reference data: Spare parts inventory coverage 95% Common parts; after-sales response ≤ 4 hoursMaintenance cycle ≤ 7 days(including logistics time), service network coverage 110 countries。
    

3. supply chain resilience: the ballast stone of long-term cooperation

Supply chain volatility is the norm, and resilience determines whether cooperation is sustainable.

Core Device Supply Strategy

Display panel:3 housesMainstream Suppliers (A/B/C Scenario)
Touch module:2 homeCore Supplier Spare
Motherboard chip: multi-brand compatible design

Safety stock and stocking plan

critical material safety stock:30-45 days

Abnormal material Freeze automatically and trigger the alert

Geopolitics and Trade Risks

Export Compliance:Ce/FCC/RoHS / CCC
No overseas factories, but through Bonded zone and diversified logistics Reduce tariff risk
Long-term agreements with shipping companies to secure space

Balance between 4. quality and cost

Low price is not equal to high cost performance, quality and delivery are equally important.

1. Price vs yield

Low-cost factories tend to have low yield, resulting in high on-site failure rates and increased after-sales costs. The total cost of ownership (TCO)= equipment purchase price maintenance repair brand loss should be compared.

        📊Qtenboard reference data:Although the unit price is slightly higher than the industry average of 3%-5%, the one-time pass rate of the whole machine is ≥ 97%, the on-site failure rate is <1.2, and TCO is 8%-12% lower than that of low-cost competitors (according to third-party calculations).

2. Delivery Date vs Customization

Fast delivery may sacrifice customization capabilities. It is necessary to confirm whether the factory has a mechanism for "standard product customization" parallel production.

        📊Qtenboard reference data: The standard production line is physically isolated from the independent OEM customization area, and the customized order does not affect the delivery date of the standard product. Customized content covers UI interface, chassis screen printing, boot animation, software pre-installation, etc. The delivery period is extended by only 3-5 days.
    

3. Size vs Focus

Large factories may have sufficient capacity, but multiple product lines may dilute the focus on interactive whiteboards; small factories focus on specific sizes but have limited capacity.

        📊Qtenboard reference data: Qtenboard Core Business Focus Interactive whiteboard and commercial display, interactive whiteboard accounted for revenue >80%; At the same time, it has a large factory scale of 330,000 ㎡, taking into account both concentration and production capacity.
    

5. due diligence list: 10 must-ask questions

The following questions can be directly used for supplier evaluation. It is recommended to print and confirm item by item in the field or video conference.

What are the actual shipments over the past 12 months? Compare brochure figures to verify capacity moisture.
What is the monthly capacity distribution for each size segment? Verify that it is good at the size you need.
How long is the change time of the production line? How long does it take to go from 65 ″ to 75?
What is the one-time pass rate (FPY) and SMT defect rate of the whole machine? A 6 month trend chart is required.
What are the standard and emergency order delivery periods respectively? How is the expedited cost calculated?
What was the order fulfillment rate for the past 12 months? How many days is the average delay for late orders?
How many suppliers are there for core devices (panel, touch, chip)? Is there a backup plan?
What are the safety inventory days for critical materials? How to deal with the peak season supply?
Do you support customized orders? How are customized and standard products scheduled? How long is the customized delivery period?
What areas does the after-sales service cover? What is the spare parts inventory and maintenance cycle?

6. take Qtenboard as an example: what does a high-capacity, high-delivery reliability foundry look like?

Capacity is not a promotional number, but a combination of actual delivery, yield and supply chain resilience.
