| Machining ● Precise instrument, marble checking platform and machining to ensure high printing precision. |
| Z Axis Servo Direct Coupling Device ● Z axis screw servo device can ensure printing accuracy, speed and stability. |
| Vacuum Clamping ● Vacuum clamping is standard configuration of H1500, thin and flex PCB can be clamped by vacuum to ensure the quality of printing. During production, PCB will be supported by magnetic tooling pins and vacuum module, this system can hold the PCB to keep it evenly, this function is useful for thin, twist and flex PCB. |
| Programmable Print Head ● It is designed to meet the need of different pressure at the front and rear squeegee and the requirement of squeegee’s leveling stability, to prevent solder paste leakage and squeegee blade with certain flexibility clamping. Squeegee pressure can be independently programmed. This provides a stable leveling of the squeegees for precise solder paste transfer. |
| Stable Electrical System ● All electrical parts with labels, customer can find out the problem depends on error message of PC and electrical drawing soon. H1500 can detect the fault by red indicating light from I/O cards, bright is normal condition, dark is abnormal. Integrated circuit and upgraded movement control card to make operation and maintenance more convenient H1500 can modify printing parameter during production process. |
| Vision System ● Uniform ring light and high brightness coaxial light, equipped with ultra adjustable brightness control, makes all types of fiducial mark well recognizable(including rugged fiducial mark) and is applicable for all type of PCB and surface treatment. CCD can read incomplete or defective fiducial mark. |
Challenge evaluation:Use black pen to cover fiducial mark over 40% ,and see whether CCD can read the fiducial mark. | |
 |  |
Find Fiducial Mark | Matched and Acceptable |
| Result: Perfect ● Softwave can read it without any problem. |
| Stencil Cleaning System ● Three types of under stencil cleaning: dry, wet and vacuum. These modes can be individually selected or combined for using. System allows manual cleaning within its operation menu which shortens cleaning time and improves production efficiency. |
| BEFORE CLEANING ● Blocked the opening of stencil by solder paste and choose 2 areas (IC and BGA )to check cleaning result. |
CLEANING RESULT | |
 |  |
Conclusion: blocked holes and IC can be cleaned completely. Customer could set up cleaning module (wet, dry and vacuum modes) depends on difficulty of stencil to improve productivity and ensure cleaning quality. | |
| Software System ● Windows XP user interface and abundant software functions, it can set printing height, squeegee pressure, printing stroke, speed, and stencil automatic cleaning cycle etc. easy to operate, you can master it within 15 minutes. |

Only 2 pages for programming, easy to operate and changeover Page 1: input PCB’s dimension, transportation direction and capture mode Page 2: fiducial mark positioning Including Operation Journal/Breakdown Record/Breakdown Diagnosis/ Error Analysis/Light Alarm | |
Key points to get a good printing quality:
The screen printing process is one of the key processes in surface mount technology that controls manufacturing yield, and it's also the station caused most of the failure in the SMT line. So to choose a right printer, we need to be careful about below points: |
● Vision System |
● Stencil Cleaning System |
● Vacuum Clamping |
● Precision Mechanical System |
● Clean & Clear software |
● Stable Electrical System |
● Z axis Servo Direct Coupling Device |
● PCB Thickness Adaptive System |
