●   Fully-automatic screen printer H1500 with automatic recognition 

function of machine vision, using high-precision servo drive system 

to achieve fast and accuracy alignment. It build in independent 

cleaning system, the cycle time lessthan 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 XP 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.

 

Machining

Machining

●   Precise instrument, marble checking platform and machining to 

ensure high printing precision.

 

Z Axis Servo Direct Coupling Device

Z Axis Servo Direct Coupling Device

●   Z axis screw servo device can ensure printing accuracy, speed 

and stability.

 

Vacuum Clamping

Vacuum Clamping

●   Vacuum clamping is  standard configuration of H1500, 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

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.

 

Stable Electrical System

Stable Electrical System

●   All electrical parts with labels, customer can find out the problem 

depends on error message of PC and electrical drawing soon. H1500 

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 H1500 can modify printing parameter during production 

process.

 

Vision System

Vision 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.

 

  Challenge evaluation:Use black pen to cover fiducial mark over 40% ,and see whether CCD can read the fiducial mark.

Stencil Cleaning System

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

BEFORE CLEANING

●   Blocked the opening of stencil by solder paste and choose 2 areas (IC and BGA )to check 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.

 

Software System

Software System

●   Windows XP 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.

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
