ng>1.保存方法ng>
ng>錫膏的保管要控制在1-10℃的環境下；錫膏的使用期限為6個月（未開封）；不可放置於陽光照射處。ng>
ng>2.使用方法（開封前）ng>
ng>開封前須將錫膏溫度回升到使用環境溫度上（25±2℃），回溫時間約3-4小時，並禁止使用其他加熱器使其溫度瞬間上升的做法；回溫後須充分攪拌，使用攪拌機的攪拌時間為1-3分鐘，視攪拌機機種而定。ng>
ng>3.使用方法（開封後）ng>
ng>1)將錫膏約2/3的量添加於鋼網上，盡量保持以不超過1罐的量於鋼網上。ng>
ng>2)視生產速度，以少量多次的添加方式補足鋼網上的錫膏量，以維持錫膏的品質。ng>
ng>3)當天為使用完的錫膏，不可與尚未使用的錫膏共同放置，應另外存放在別的容器之中。錫膏開封後在室溫下建議24小時內用完。ng>
ng>4)隔天使用時應先行使用新開封的錫膏，並將前一天未使用完的錫膏與新錫膏以1：2的比例攪拌混合，並以少量多次的方式添加使用。ng>
ng>5)錫膏印刷在基板後，建議於4-6小時內放置零件進入回焊爐完成著裝。ng>
ng>6)換線超過1小時以上，請於換線前將錫膏從鋼板上刮起收入錫膏罐內封蓋。ng>
ng>7)錫膏連續印刷24小時後，由於空氣粉塵等污染，為確保產品品質，請按照“步驟4）”的方法。ng>
ng>8)為確保印刷品質建議每4小時將鋼板雙麵的開口以人工方式進行擦拭。ng>
ng>9)室內溫度請控制與22-28℃，濕度RH30-60%為最好的作業環境。ng>
ng>10)欲擦拭印刷錯誤的基板，建議使用工業酒精或工業清洗劑ng>

ng>焊後清洗ng> |
ng>9037系列屬於免洗錫膏。一般應用時無需清洗焊後殘留物。ng> ng>如需進行清洗，9037系列焊後殘留物也很容易借助保奇相對應的清洗劑清洗。ng> |
ng>包裝形式 ng> | ng>瓶裝 --每瓶250克和500克可供選擇ng> |
ng>貯存、操作及保存期限ng> |
ng>9037在5-10℃條件下可保存6個月。註意不要對錫膏進行冷凍處理。ng> ng>錫膏打開包裝使用前需進行充分回溫到室溫（推薦4個小時）ng> ng>冷藏保存時可能會引起錫膏內組分的分離，使用前充分攪拌錫膏1-5分鐘以充分混合均勻。ng> ng>不要將用剩的錫膏與新的錫膏混合在同一包裝內。錫膏不需要使用時應重新進行密封，當瓶蓋不能很好地進行密封保存時請更換瓶蓋內襯以保證盡可能的密封。ng> |
