Solder paste and red glue printing machine
Core features (biggest difference from traditional printing machines)
1. Visual Alignment System
. This is the most essential characteristic. The machine takes photos of the reference points (Fiducial mark) on the PCB and the reference points on the steel mesh through a high-resolution camera.. The software algorithm will calculate the small of set (X, Y, 0 direction)between the PCB and the steel mesh, and automatically adjust the position of the platform or steel mesh to achieve precise alignment.. Function: It greatly compensates for PCB manufacturing errors,
clamping deviations,and thermal expansion effects, ensuring perfect alignment of solder pads and steel meh openings, which a prerequisite for obtaining high quality printing results.
2. High precision and high repeatability With he help of visual alignment and precision servo motors linear motor, the alignment accuracy of modem visual printing machines can usually reach t 0.0lmm or even higher.
The printing repeal ability (Cpk) is usually required to be greater than 1.67, providing a solid foundation for subsequent surface mount and reflow soldering processes and reducing defects caused by poor printing.
3. Closed loop control system
. Scraper pressure control:
Programmable control of scraper pressure,speed, and angle to ensure optimal rolling and filing effects of solder paste. Constant pressure mode is more advanced than simple stroke control.
. Demoulding control: The demouling sped,distance,and delay can be accurately set to ensure that the solder paste is perfectly transferred form the opening to the solder
pad, avoiding defects such as "dog cars" or sharp edges.
. Automatic height control: some device are equipped with laser sensors that automatically detect PCB warping and adjust printing height ensure that the scraper plane is parallel to the PCB plane.
