Fully Automatic Screen Printer H12 & H15

Fully Automatic Screen Printer H12 & H15

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.

 

Arch bridge type suspending direct-connected scraper programmable printing head.

Arch bridge type suspending direct-connected scraper programmable printing head.

Double sliders ensures the printing head moving accuracy and stability when scraper is running back and forth.

The cleaning unit is separated from CCD camera, which can minimize the camera & stop axis load, improve the PCB positioning precision and speed.  Stencil cleaning system is automatic and effective. Three models  of Dry cleaning. Wet cleaning and Vacuum cleaning can be selected to use individually and multiply.

Fully-Automatic Screen Printer

Stencil Cleaning System

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.

Stencil Cleaning System

BEFORE CLEANING

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

BEFORE CLEANING

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.

CLEANING RESULT

Printing Result Comparation

500X Microscope Inspection

Printing Result Comparation

Conclusion: Printing result is perfect, no misalignment, shift, solder bridge, lack solder, etc.

Printing Result Comparation

Use same sample to test H4E and other brand to check IC and BGA.
