Automatic Screen Printer H450

Quick Overview
Vision Alignment Automatic Screen Printer

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.jpg

Optical 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 .


3 types of under stencil cleaning.jpg

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.


Top Clamping.JPG

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 



Vacuum Clamping.jpg

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.jpg

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.jpg

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.jpg

Programming Software

Only 2 pages for programming, easy to operate and changeover. 

Including Operation Journal/Breakdown Record/Breakdown Diagnosis/ 

Error Analysis/Light Alarm.
