Fully Automatic Screen Printer H1200

Quick Overview
Special for LED board and long PCB printing

Fully-automatic screen printer H1200 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 than 10s,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 industrial PC ,with Windows 7 OS 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.

Fully Automatic Screen Printer H1200 Features

Flexible Auto Clamp system.

Very stable machined cast structure.

Auto conveyor width adjustment.

Adjustable width/thickness for stencil frames.

User friendly, Windows 7 OS, intuitive operation.

Stencil position memory function for easy and quick change over.

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.

Fully Automatic Screen Printer H1200 Details

Precise instrument, marble checking platform

and machining to ensure high printing precision.

Z axis screw servo device can

ensure printing accuracy ,speed and stability.

Z Axis Servo Direct Coupling Device

 



 Three Stage Conveyor (option) ,The cycle

time shortened by one second than one stage.

 Vacuum clamping is  standard configuration of H1200,

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.

3 stage conveyor(option)

 Vacuum Clamping

 


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.


 All electrical parts with labels, customer can find out the

problem depends on error message of PC and electrical

drawing soon. H1200 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

H1200 can modify printing parameter during

production process.

 Fully Automatic Screen Printer H1200 Vision System & Software

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.

Result: Perfect !!! Softwave can read it without any problem.

Windows 7 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.

2D inspection system immediately detects solder paste deposition defects, such as deviation, lack

solder paste, miss solder paste, misalignment , solder bridge, etc to ensure print quality.

Fully Automatic Screen Printer H1200 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.
