一 、Products introduction :
Acid cleaning agent LT - 1810c for electroplating, may remove the surface of copper mild grease and oxides, so that the surface activation and clean acidic cleaning agents.
二、 Feature:
1、 Remove the dirt surface of the copper and activite it, and formed the most suitable for electroplating in the surface state.
2、 In the printed circuit board manufacturing process will not damage the preapplied Mask (Sold Mask).
3、 Washing performance and antifoaming are good.
三、 Construction bath method：Purity Water : 90% (V / V)
LT -1810c ：8%-12%（V/V）
四、 Operation standar
1、 temperature: normal
2、 time: 3-5 minuts
3、 mixture: mechanism swing
4、 Groove plating materials: Using PVC liner SUS - 316 or SUS - 304 Slot
5、 Heater material: quartz or Heater
五、 Note：
1、 After washing three of the required cleaning, the first paragraph of the best 40 -50 ℃ warm water.
2、 LT -1810cacidic liquid, Please don’t splash it on your body or eyes while using.
六、 Groove liquor maintenance：
1、 Fixed added: 1m2 per plate processing to supplement the following: LT - 1018c 22ml;
2、 Standard for changing groove: Accumulated amounts up to two times of the amount slotted.
七 、Performance and packing
1、 Appearance : colorless, transparent liquid acid
2、 Packaging : 20 liters / barrel
八、 Groove liquor maintenance :
1、 Drop 20ml sample into the cone bottle
2、 Add 50ml deionized water and 3-5 drops phenolphthalein indicator;
3、 Using 1.0N NaOH standard hydroxide solution titration, when a drip to the dignitaries does not disappear for half a minute;
4、 Calculation: acidic cleaning agents acid equivalent = 1 / 20 * 1.0N sodium hydroxide titration ml
5、 Control range：0.3-0.8（N） |
