      OCXO選型與采購
      2016年03月10日

      恒溫晶振OCXO選型和采購時應該注意的問題
      1)不要一味追求高指標,因為高指標意味著成本大幅度增加,交貨期加長
      2)注意封裝的可替代性,盡量不選用非標準封裝
      3)盡量不要壓縮供應商的交貨期限,有可能的情況下,盡量提供需求預測,要求廠家備貨,至少做好晶體的備貨、老化、篩選工作。
      4)了解供應商情況的時候,應該著重考察供應商的晶體來源、工藝控制能力、通信行業客戶情況,最好定期做現場考察。供應商沒有批量出過貨的產品,采購時應非常小心。
      5)選擇供應商時,盡量選擇有較強技術支持能力的廠家。
      6)如果可能的話,應允許供應商在研發階段就參與到指標的確認工作中。

      Attentions of OCXO selection and procurement
      Attentions of testing and debugging OCXO
      1) Do not blindly pursue high index, since a significant increase in the high index means that the cost and delivery time lengthened.
      2) Note the fungibility of packaging, try not to choose a non-standard packaging.
      3) Do not compress the supplier delivery time, where possible, try to provide demand forecasting,then require manufacturers stocking up, at least do a good job in stocking, aging and screening of crystal.
      4) When learning a manufacture, we should focus on the crystal source, process control ability and communications customer information of manufacture, the best situation is regular site visits. If the manufacture have not been provided batches products, procurement should be very careful.
      5) When choosing suppliers, try to choose a manufacture which have strong technical support capabilities.
      6) If possible, the supplier should be allowed to participate in the development stage of indexes confirmation.
