Arch bridge type suspending direct-connected scraper programmable printing head. Double sliders ensures the printing head moving accuracy and stability when scraper is running back and forth. |
|
|
Special platform calibration: Three axes linkage is designed with super-high dynamic characteristics to achieve high precision platform calibration. |
|
|
The cleaning unit is separated from CCD camera, which can minimize the camera & stop axis load, improve the PCB positioning precision and speed. Stencil cleaning system is automatic and effective. Three models of Dry cleaning. Wet cleaning and Vacuum cleaning can be selected to use individually and multiply. |
|
|
Unique belt transmission system avoids being stuck or fall-off of PCB Programmable motor controls conveying speed and conveys PCB in the precise position Conveyor width can be automatically adjusted. |
|
|
Uniform ring light, high brightness coaxial light and advanced upper/lower visionsystem Full range of light compensation, Automatic and accurate recognized of alltype MARK points. Applicable for tin plating, copper plating, gold plating, tin spraying.FPC and other types PCB with different colors, able to ensure high accuracy. |
|
|
Using Windows 10 operation interface, and easy to learn for user. Programming is designed with teaching and navigation function, guidance is available on every step. |
|
|
High quality electrical parts ensure machine long service life. |
|
Stencil Cleaning System |
|
|
3 types of under stencil cleaning: dry, wet and vacuum. These 3 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. |
|
|
Printing Result Comparation |
|
|
500X Microscope Inspection |
|
|
|
Conclusion: Printing result is perfect, no misalignment, shift, solder bridge, lack solder, etc. |
|
|
Use same sample to test H4E and other brand to check IC and BGA. |
|
Printing Result Comparation (SPI) |
|
|
SPI inspection |
|
|
|
SPI inspection result:
Production QTY: 192PCS |
|
|
Conclusion: This PCB has many difficult IC and small pads, after inspection, result is good, H4E can ensure printing quality and accuracy in production line. |
