1、環境條件 : 相對濕度:40%-70%; 溫度:23 4,照明:11001300LUX Environment : relative humidity:40%70%, Temperature:234,lighting:11001300LUX 使用設備: QUICK203H電烙铁 Using Equipment: QUICK203H Solder Iron 助焊膏使用要求: 按HP輔料要求標準 EL-MF862-07 14條規定. Using flux cream demand: according to 14 spec the HP assistant materials EL-MF862-0
2、7 of standard.,1.设置烙铁温度為360380度之間; Set Iron proper temperatures:360380 2.將1pc PCBA平放於治具中. Put a PCBA in the fixture and make sure that is on right place. 3.再取1PC WIFI天線,將WIFI天線的兩個腳對准PCBA上相對應的兩個孔.(如圖一） Made the Antenna WIFI pin aim at the PCBAs two hole of speaker location. (Fig.2) 4.用牙簽取少量助焊膏, 塗抹於PC
3、BA相應的WIFI天線焊點上,然後用手按住WIFI天線,防止其偏移,用烙鐵進行焊接(圖二),直到觀察焊錫完全熔化(12秒) Adding some flux with tooth pin onto the soldering pad of the Antenna WIFI. Then, press WIFI antenna to avoid shifting, and then solder with iron until all the solder melted (the time 12s) .(Fig.2) 注意: 焊接過程中, 烙鐵不能碰到Antenna WIFI,以免燙壞Antenn
4、a WIFI. Notice: Do not bump or knock the part by iron during manual solder. 5.焊接完畢後, 按壓WIFI天線的動作不應立即停止,應持續23秒,以防由於板受熱變形,影響焊接效果 When the solder finish, the Action of press Antenna WIFI dont stop offhanded,. Should sustained23s, prevent the thin PCBA distortion due to adding hot Influence the solder e
5、ffect. 6.在主板的BT天線兩個Pad點上涂上適量的助焊膏.然后插上BT天線,確保卡合到位,用手指按住BT天線,再用鉻鐵進行焊接,直到觀察焊錫完全熔化(12秒) Add some solder flux onto the two pads of BT, then insert the BT antenna to make sure it properly engaged into the PCBA and then solder with iron until all the solder melt (the time 12s) . 7.焊接完畢後,按壓BT天線的動作不應立即停止,應持續
6、23秒,以防由於板受熱變形,影響焊接效果 When the solder finish, the Action of press Antenna BT dont stop offhanded,. Should sustained23s, prevent the thin PCBA distortion due to adding hot Influence the solder effect. 8. 檢查WIFI天線和BT天線有無偏位, 焊點焊錫是否均勻平整,(圖四) 確認OK後流入下一工站. Inspection the Antenna WIFI and ANTENNA_BT locatio
7、n if shift and solder pad if level up with magnifier ,(Fig.4) if ok places inflow the next station.,1. 檢查所需治具與工具,是否與要生產機種相符且功能 正常,若有問題請通知領班協助處理。 Make sure the fixture and tools required are in accordance with the model produced and their functions are OK. Inform line supervisor if there is any probl
8、em.(Fig.1-2) 2. 作業員需配戴靜電環和手指套,并且靜電環接於桌子 下方接地插孔。 Operator must wear wrist straps and finger cover. Ensure that the wrist strap is plugged into the hole desk below which connect with the ground. 3. 作業員應對此工站的完成件進行自檢,注意WIFI天 線和BT天線組裝方向不能反向。 Operator self-check sub-assy after finished operation 4. 整個操作過程
9、中注意不可碰撞電子元件。 No component damaged in the whole operation. 5.焊盘上要有适当数量的锡避免虚焊. No touch ups are allowed (Fill lands with a good amount of solder to avoid unsolder leads).,圖 一 Fig.1,焊接時需用手按住WIFI天線,防止其脫落及偏移 Press WIFI antenna for soldering to avoid Shifting,圖二 Fig.2,圖三 Fig.3,WIFI天線上的兩個孔位 Two holes for WIFI,焊點焊錫要均勻平整 The solder of pad should be level up,圖四 Fig.4,焊接時需用手按住BT天線,防止其脫落及偏移 Press BT antenna during soldering to avoid shifting,焊接BT&WIFI Solder BT&WIFI,1,電烙鐵,助焊膏 固定治具,
