使用說明/注意事項
1、 滾塗
1)滾塗與烘烤條件
1.1滾塗膜厚與油墨及操作條件有關,建議乾燥後膜厚為8-12um,統計資料表明:當膜厚控制在8-12 um的時候,1公斤油墨可塗布的面積為150-160平方尺。其影響膜厚和塗布面積的因素有:
油墨粘度越高,塗膜厚度越厚。塗布面積越少。
塗布滾輪間隙越大,塗膜厚度越厚。塗布面積越少。
油槽間隙越大,塗膜厚度越厚。塗布面積越少。
塗布輪轉速越快,塗膜厚度越厚。塗布面積越少。
1.2設定適當的稀釋劑自動添加頻率與每次添加量使油墨粘度恒維 持在適當粘度及塗膜厚度範圍。
1.3適用于自動水準或垂直式自動線滾塗機及手動單面滾塗機,烘烤溫度與時間以使板溫度到達80-180℃維持至少60秒以上,然後進行必要之冷卻。
1.4乾燥條件可依膜厚及烤箱狀況做適當調整。
乾燥過度會引起顯影不潔留下殘渣(SCUM),乾燥不足塗膜呈感壓粘性,曝光時底片易粘油墨,顯像時也會導致部份被洗除,無法進行抗蝕刻。
2)注意事項
2.1塗布室必須保持乾淨,否則灰塵等會造成線路不良與困擾。
2.2塗布作業必須在黃色燈光照明室內。
2.3罐內有未倒盡油墨時,請隨時蓋好罐蓋以防止粘度增高。
2.4自動線滾塗機操作中因故停機或其他原因造成油墨槽粘度上升時請進行必要之稀釋,調整粘度或作粘度控制時,請用本公司指定的專用稀釋劑(PMA)。
2、烘烤
1)以板面實際溫度達到80-180℃,60秒以上。
2)注意事項
2.1乾燥條件可依膜厚及烤箱狀況做適當之調整,以上條件僅供參考。
2.2乾燥過度會導致後續顯影時留下殘渣。
2.3乾燥不足塗膜呈粘性,曝光時底片易粘油墨,顯像時會部分被洗除,導致後續蝕刻時無法抗住蝕刻。

Note
1. Rolling coating
1)Rolling coating conditions
1.1Rolling coat thickness is related to the working conditions. It is recommended that the thickness is 8-12um.The statistics is showed 1kg ink covering 150-160 square feet with 8-12um thick. The coat thickness is affected as follows
The higher viscosity, the thicker coat, the less coating area
The larger clearance between rollers, the thicker coat, the less coating area
The larger ink tank clearance, the thicker coat, the less coating area.
The faster rolling speed, the thicker coat, the less coating area
1.2 Set up the proper frequency for automatic dilution adding system to stabilize the viscosity for required thickness range
1.3 Drying at 80-180℃ at least 60sec and cooling on the automatic horizontal, vertical or manual one side rolling coating machine.
1.4 Optimize the drying conditions according to coating thickness and oven.
Over drying will result in residue(SCUM). Under drying will result ink transferred to film during exposure and ink removed during developing. Etch resistance will fail due to either under or over drying.
2)Note
2.1
Work in the clean room to avoid circuit failure
2.2
Always work under yellow illumination
3.3
Keep the ink sealed to avoid higher viscosity, if it is not used up
2.4
The dilution is necessary if there is higher viscosity happen, because of the machine down or other accidents. Always use our thinner (PMA) for dilution.
2、Baking
1)Temperature at PCB surface: 80-180℃,more than 60sec 2)Note
2.1
The above baking condition is just for your information. Attain the baking conditions according to coat thickness and oven particularly.
2.2
Over baking will cause residue during developing next.
2.3
Under baking will cause ink transferred to film during exposure and ink removed during developing. Etch resistance will fail due to either under or over baking.

3)Note
3.1
Detect 9 points for exposure intensive uniform with UV energy meter. The uniform should not be less than 80%.
3.2
Not enough exposure energy will cause coating off or insufficient resolution.
3. 3
Over exposure energy will cause exposure defect and longer stripping time, though it can attain better etch resistance.

The developing rate will be affected by either thicker or thinner of developing solution. The concentration should be controlled properly. The standard value is 1% ranging from 0.8% to 1.2%.
2、 The coating surface will be damaged if the developing is too long or temperature too high. The developing time and temperature should be controlled properly. The developing time depends on the breaking point. The thicker the coating, the longer the developing time. The typical value is not more than 45sec.
