A two milimeter diameter hole is added to the center of the bottom of each tray to reduce the risk of deformation of the tray due to pressure differences during vacuum packing. 3. 变更描述/Description of Change 目前正在量产的料带底部为平整设计。此次变更在料带底部增加了网格结构以增加料带的总体刚度和压缩强度。 www.espressif.com Page 2 / 7 同时在料带底部的中心增加了直径为两毫米的通孔以平衡抽真空过程中形成的内外压差。 The bottom of the tray of the current tape reel is flat. In this change, cross patterns are embossed to the bottom of the tray to increase the overall rigidity and compressive strength of each tray. A two milimeter diameter hole is added to the center of the bottom of each tray to allow the pressure in the tray to equalize during vacuum packing. 4. 变更对比/Change Comparison 请见附录 I：变更对比。 Please refer to Appendix I: Change comparison. 5. 变更影响/Impact of Change 品质和性能/Quality & Performance: 对模组品质和性能无影响. 增强 ESP8266/ESP32/ESP32-S2 系列模组料带的刚度和压缩强度可以更好地防止在卷料和抽真空过程中发生形变。 There is no impact to the quality and performance of the modules. The rigidity and compressive strength of each tray of the ESP8266/ESP32/ESP32-S2 module series tape reel is increased to better resist deformation during reeling and vacuum packing. 交期/Delivery: 对于段落 1 列出模组产品的交期没有影响。 There is no impact to delivery performance of the affected Espressif modules listed in para 1. 生产料号/Material Part Numbers (MPN): 无需对段落 1 列出模组产品的 MPN 做出变更。客户可以用原有的 MPN 下单。 There is no change to the MPN of the affected Espressif modules listed in para 1. Customers can continue to use existing MPN to place orders. 认证/Certification: 该变更对 Wifi 和蓝牙的性能没有影响，因此对已有 Wifi 和蓝牙的认证的有效性没有影响。 The change does not affect the Wifi and BT performance of the modules and does not affect the validity of their existing Wifi and BT certifications. 其他/Others: NA 6. 变更前后产品处理/How to Deal with Products FIFO www.espressif.com Page 3 / 7 7. 相关报告/Report(s) Attached: Related ECN No. ECN-2020-031/ECN-2020-032 Material Qualification Report Performance Test Report Reliability Test Report Environment Related Report (RoHS / REACH / HF) Certification Other Reports (Pls specify) 料带改善验证报告/Tape & Reel Verification Test Report www.espressif.com Page 4 / 7 Appendix I 变更对比/Change Comparison 模组/Module 变更前/Before Change 变更后/After Change ESP-WROOM-02 ESP-WROOM-02D ESP-WROOM-02DC 20.5*18.5.*3.7mm 20.5*18.5*4.1mm, Hole D=2mm ESP-WROOM-02U ESP-WROOM-02UC 14.8*18.5*3.7mm 14.8*18.5*4.0mm, Hole D=2mm ESP32-WROOM-32 ESP32-WROOM-32D ESP32-WROOM-32E ESP32-WROOM-32DC ESP32-WROOM-32SE ESP32-SOLO-1 ESP32-SOLO-1C ESP32-S2-SOLO 26.2*18.9*3.5mm 26.2*18.9*3.8mm, Hole D=2mm ESP32-WROOM-32U ESP32-WROOM-32UC ESP32-WROOM-32UE ESP32-S2-SOLO-U 19.6*18.5*3.7mm 19.6*18.5*4.0mm, Hole D=2mm www.espressif.com Page 5 / 7 ESP32-WROVER (PCB/IPEX) ESP32-WROVER-B (PCB/IPEX) ESP32-WROVER-E ESP32-WROVER-IE 31.8*18.4*3.4mm 31.8*18.4*4.1mm, Hole D=2mm ESP32-S2-WROVER ESP32-S2-WROVER-I ESP32-S2-WROOM ESP32-S2-WROOM-I 31.8*18.4*3.4mm 31.8*18.4*4.1mm, Hole D=2mm ESP-WROOM-S2 24.6*17.1*3.4mm 24.6*17.1*3.7mm, Hole D=2mm ESP-WROOM-5C 19.5*16.5*3.7mm 19.5*16.5*4.2mm, Hole D=2mm www.espressif.com Page 6 / 7 邮件订阅 Espressif Email Notifications 乐鑫为注册用户提供电子邮件通知服务，用户可通过乐鑫订阅系统接收技术文档更新、新闻通讯、PCN 等邮件通知。 Espressif sends email notifications of technical documentation changes, along with newsletters, PCNs and other valuable information, to subscribed customers only.
