H450 with automatic recognition function of machine vision, using high-precision Servo drive system to achieve fast and accuracy alignment .The precision can reach +/- 0.01mm.It build in independent cleaning system, the cycle time less than7s,ensure the high printing quality of solder paste and ultimate product efficiency. It also can print 0.3mm ultra fine pitch pad perfectly .This machine controlled by computer ,with Windows XP user interface and abundant software functions, it can set printing height, squeegee pressure, printing stroke, speed, and stencil automatic cleaning cycle etc. by software .It designed to keep the stability of printing quality, and greatly facilitate to users.
Optical System 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 . | |
3 types of under stencil cleaning combined for using. System allows manual cleaning within its operation menu which shortens cleaning time and improves production efficiency. | |
Top Clamping Top clamping system can ensure PCB flatness before printing, 2 piece tabletting press the edge of the PCB ,twist and warpage would be eliminated. | |
Vacuum Clamping (Option) vacuum clamping is an option of H450, 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. | |
Motion System Squeegee Y-axis servo screw drive with higher precision and more stable operation, extend the service life; built-in precise pressure control system, the sgueegee can be accurately measured raw pressure value, providing customers a good printing control platform. | |
Programming Software Only 2 pages for programming, easy to operate and changeover. Including Operation Journal/Breakdown Record/Breakdown Diagnosis/ Error Analysis/Light Alarm. |
