AI-Powered supplier vetting

SummaryShenzhen JCHL Technology Co., Ltd. is identified as a trading company and professional electronic components supplier with more than ten years of history. It offers customization, ODM services, inventory capability, quality assurance, raw-material traceability, and reported new products in the past year. Service procedures exist for supplier assessment, corrective actions, and complaint handling, but written records are absent. The supplier does not provide 3D software design, does not operate overseas warehouses, showrooms, agents, or branches, and has not participated in offline trade shows. The available information does not establish certification ownership, financial credibility, production capacity, or customer cases.

Supplier typeThe company is described as a private enterprise and professional electronic components supplier, while its company type and nature are explicitly classified as a trading company. Its activities include research and technology development, production, sales, and agency distribution, but the supplied classification indicates a trading-company profile.

After-Sales capabilityThe supplier has a complaint-handling procedure, inventory service capability, stated lead times within 15 workdays in both off-season and peak season, and accepts multiple service quotation and payment terms. However, the complaint procedure has no written records, and the supplier has no overseas warehouse, showroom, agent, or branch, limiting documented after-sales infrastructure outside its home market.

R&D capabilityThe supplier reports scientific research and technology development activities, new products within the past year, and ODM service availability. However, it is explicitly not identified as a professional technical supplier, does not provide 3D software design services, and has no available SDK.

Production capacityThe company states that it engages in production of sensitive components and optical elements and has finished-product inspection instructions that are uniformly followed. Nevertheless, the available information does not provide production capacity, facility scale, equipment, or output data.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This directly demonstrates broad stated customization coverage, although 3D software design services are not offered.

Product Q&A

Q:How are the sensing parameters measured?

The sensor's factory parameter testing is obtained after a one-minute stabilization period under a standard blackbody and relevant circuit conditions. The sensor's sensing distance is a multidimensional function of parameters such as background temperature, moving target temperature, Fresnel lens target distance, ambient humidity, amplifier gain, and comparison voltage.

Q:What should be paid attention to during welding?

It is recommended to solder the sensor base lead at a position above 4 millimeters, and the soldering time should be as short as possible.

Q:What should be paid attention to when storing and taking out goods?

Do not touch the window directly with hands or hard objects. Prevent strong vibrations and static electricity generation.

Q:What is the minimum order quantity?

The minimum order quantity is 1000 pieces.

Q:What are the available payment terms?

We accept LC, T/T, D/P, PayPal, Western Union, and small-amount payments.
