| Elite Etch/EE Cu | Remark | |
| Machine size (mm) | 190x320x305 | The Elite EtchDecap has a more sophisticated design and occupies a smaller area, saving customers space. A ventilation cabinet of 1.2 meters is sufficient. |
| Temperature range | 1. Smoke sulfuric acid: 20C-250C2, smoke nitric acid: 20C-90C3, mixed acid: 20C-100C (EE) 4, mixed acid (patent): 10C-100C (EE Cu) | If the customer's copper wire is less than 0.7MIL, Elite Etch Decap can be upgraded to Elite EtchCu, which has a low-temperature cooling system with USA patents and a minimum mixed acid of 10C. |
| Acid extraction flow rate | l-8ml/minute | Elite Etch has a wide flow range and faster speed. |
| Etching head component | Fixed silicon carbide (2-year warranty) | Elite Etch comes with a 2-year warranty. |
| N2 gas support | 2.0lpm (safety cover+pump) 60-70psi | ElieEtch saves more N2 gas. Adopting an automatic high and low pressure gas conversion system and supplementing the internal safety pressure of the safety cover. There will be no CHECK COVER alarm. |
| Safety | 1. Automatically display error messages. 2. EMO emergency stop button. 3. Acid leakage detection is located inside the equipment and in the bottle box. 4. It uses fiber optic sensing to measure the tightness of the lid (not consumables). 5. All pipelines are designed to be integrated, with a double-layer protective cover, and the acid bottle box is equipped with a lid | The EMO emergency stop button and acid leakage fiber optic detection are located inside the equipment and in the bottle box. The pipeline has a double-layer protective cover, and the acid bottle box is equipped with a lid, which only EliteEtch has for a safer design. |
| Waste acid bottle | 1 piece | EliteEtch's newly designed acid return cooling system can return waste acid into one bottle, reducing the consumables and maintenance of one acid return valve component. |
| Fixed sample method | After the lid is closed, it automatically fixes the sample directly from top to bottom | The EliteEtch design does not have a similar situation and its positioning is relatively accurate. |
| Sealing ring | Round (not consumable) | EliteEtch's sealing ring is a circular design with high density and does not require replacement. |
| Operation method | Can be manually operated outside the fume hood (safer) | The operation and machine of EliteEtch are separate. Less susceptible to acid erosion. |
| Warranty period | 1. Complete machine warranty for 1 year 2. Etching head warranty for 2 years 3. New micro pump warranty for 2 years | The warranty period for Elite Etch is longer. |
| Automatic acid cleaning option | 0-20 seconds (optional sulfuric acid, nitric acid, mixed acid cleaning or no cleaning) | Mixable acid cleaning is a special design of EliteEtch. Can be used in copper wire applications. |
| Security proof | 1,CE2,SEMIS3-933,SEMIS20004,RoHS | EliteEtch is more in line with global safety standards. |
| Opening washer | There are 7 sets of standard gaskets and customized gaskets according to customers. | Can be shared |
| Etching method | Pulse type and reciprocal type | Only the unique design of Elite Etch allows for corresponding parameter adjustments when operating pulse, reciprocal, or automatic pickling. |
● Elite Etch/ECu System for Packing Opening
● The temperature of the acid can be set to+10Cto250C. When there are a large number of copper wire products and copper wire below 0.7mil, it can be upgraded to EECu
