    A According to Nationstar's public website, the first generation of Nationstar's new micro LED product - nStarⅠ2.7-inch display module is officially launched

  • Q Will Atop become an OBM in future?

    A Atop is enthusiastic about becoming one of the major producers and exporters of OBM of stage led display . We supply the maximum quality merchandise for the marketplace. Each phase in design, manufacturing, and renovation to closing scheduling is performed by an extremely trained group of professionals with years of experience. Manufactured in accordance with standardized manufacturing practices and approaches, our products work well in most facets.

  • Q Is Atop an OBM?

    A Atop is not experienced enough to being an OBM. But we are professional in offering ODM and OEM service for you. OBM is the abbreviation of Original Brand Manufacture which refers to a manufacturer who creates its own product brand as well as produces and sells products with its own brand. It is a great challenge for us to develop into an OBM, which requires the strong support of complete sales network and channel establishment.

  • Q How about the minimum order value for ODM products?

    A Please contact Atop customer service team for the minimum order value for specific ODM products. Our quotation will contain all information like product specifications, grade, payment terms, packaging, and MOQ. As for the MOQ or MOV, we need to consider factors like product type, cost, and mode of transportation, our production capacity, level of customization and our individual policy.

  • Q How about the minimum order quantity for ODM products?

    A The minimum order quantity for each product under Atop is different. Please check on the product page. Manufacturers typically offer lower MOQ for ODM products, as compared to OEM products. From their perspective, it’s far easier to take ODM than OEM. It’s less time consuming and also less risky because they are already experienced with the specific design. In addition, the manufacturers can use their existing materials and component subcontractors instead of being forced to search for new subcontractors.

  • Q How long it will take for ODM processing?

    A It depends. To learn more, please consult with our customer services. We've got an abundance of expertise, abilities and research and development tools to earn any ODM integration a complete victory! With an extremely concentrated effort, we supply you with industry-level services and products. We'll work until you're satisfied and the item just meets your requirements.

  • Q How about the ODM service flow?

    A Atop adheres to a consistent and highly-efficient service flow for the manufacturing of the ODM order. It is almost the same as our ordinary production flow, except that we will review and discuss with our customers about the specifications you provide. The design we provide is guaranteed to be applicable and feasible, combining the specifications offered. The production process is conducted in a fast manner so as to meet the due time of the ODM order. We never slack off in the quality control of ODMed products. To ensure a high pass rate and reduce manufacturing cost, we strictly stick to the QC standards.

  • Q Does Atop provide ODM service?

    A If you have limited resources in building and creating designs, Atop can turn the concepts into concrete and tangible items. Tell us what are needs and expectations. In this approach, we take care of the R&D, product concepts, testing and manufacturing. A visit to our factory is welcomed. It will help you to gain an insider's perspective to us and to know how we operate.

  • Q How about the minimum order value for OEM products?

    A The MOV is related to the MOQ in Atop. It may be counted based on the MOQ and the price per unit. Contact us first and a negotiation is allowed. The MOV is set to ensure that the order is worthwhile for the business. The reduction of MOV is possible when it is the off season OR mix production is OK.

  • Q How about the minimum order quantity for OEM products?

    A You'd better make direct contact with our staff for the exact minimum order quantity for the OEM products. Due to the influence of the processing industry chain, Atop needs to purchase materials such as packaging materials and raw materials from upstream enterprises who also demand a MOQ for some kinds of materials. In addition, considering our production cost and other expenses, it's reasonable to set a MOQ for the OEM products, which can ensure that we won't take the risks of losing the lowest cost.
