The PCB loading direction can be selected and combined freely.
Unique crafted internal gear conveyor belt to prevent jamming
Programmable transport speed control makes PCB stop more precise
Adopt flexible side clamps and segmented supports to effectively clamp the PCB to ensure a fully balanced contact between the PCB and the steel mesh
The optimally designed module drive structure effectively improves the stability of the platform calibration, and realizes ultra-small transmission under fine-tuning, so that the machine can meet the printing requirements of higher precision.The structure is simple and reliable, the adjustment is convenient, and the height adjustment of the support PIN of the PCB board with different thicknesses can be quickly realized.
ET5235 automatic solder paste printing machine is our latest research product. Its PCB board printing size is 520mm*350mm, and the minimum is 50*50mm.
It has five major sections: PCB transportation and positioning system, steel mesh positioning system, scraper system, operating system, image and optical path system. The printing of the PCB is very fine, and the scale is embedded, which will never fall off, increasing the service life and accuracy.
The SMT printing machine is a machine and equipment that uses the opening of the stencil to leak the electronic fiber material (solder paste, patch glue, etc.) to the circuit board in the SMT electronic assembly process. The purpose is to stick the chip electronic components. device.
Printing Problems and Analysis
Printing offset:
The printing offset of the first piece before the machine change line production
PCB mark is not good
Poor PCB clamping
The machine Vision system fails and the machine XY Table has problems
solder paste bridge
The steel plate is scratched or insufficient tension
The steel plate is not wiped well
Whether the tape on the back of the steel plate has fallen off
There is solder paste on the back of the steel plate
There are protrusions on the surface of the PCB parts
The XY Table of the printing machine is inclined, and there is a gap between the guide and the steel plate
The levelness of the squeegee of the printing machine is poorly corrected, resulting in the phenomenon of excessive tin in the printing solder paste
Solder paste plug
Solder paste is too dry
Slow Snap off Speed is set too fast
Slow Snap off distance is set too small
Solder paste collapses
Solder paste viscosity is too low or inhaled moisture
The scraper speed is too fast
Less printing and missing solder paste
The amount of solder paste on the steel plate is small
Solder paste scraper
Solder paste tip
Slow Snap-off speed setting is too fast
The gap between PCB and STENCIL is too large
The squeegee printing speed is set too high
The blade pressure setting is too low
The board support is not enough
Solder paste is too thin
The amount of solder paste on the steel plate is small
The squeegee printing speed is set too high
Solder paste scraper
Solder paste is too thick
There are protrusions on the surface of the PCB parts ﹒
