Here it is the new Dispenser V5 with additional function of adjustment of Oozing!!
The PCB is white in V5 to be different as in V4. There are as well other important improvements in optimization of Torque which is Crucial for dispensing quality with respect to amount of solder paste in Syringe.
Users of V4 of my Dispenser have confirmed quality of dispensing solder paste, liquids, oil and reliability of Dispensing on numerous projects. In addition, this version V5 has upgraded usage of power of stepper motor and as well less heat from electronics and motor due to current limitations trough the motor when no command is given to the motor.
Dispenser is operated with one hand and all controls are in your hand!
Key Functions V5:
Joystick to control & turn stepper motor shaft left or right and move piston in direction chosen by joystick. Automatic is auto reverse for Oozing control. Green LED indicates motor rotation in any direction. Stepper motor has auto reverse movement to prevent continues flow of paste (or liquid,..) through the needle (oozing control). Auto reverse can be user adjusted with trimmer on PCB.
Stepper speed is additionally controlled with joystick – 5 speed and 5 LEDs to precise control dispensing. Auto reverse is in effect after each dispense to minimise oozing.
Very powerful stepper motor with full metal gears & tremendous pressure is used for SMD SMT solder paste compressing in syringe to flow through the needle and drop to PCB.
Power Supply needed is 5V DC – 0.5-1A – use USB cable and phone charger or computer USB port…or similar.

(do not use this softwere for earlier Versions V 1-4!).
Please use quality solder paste with valid pot-life from date of manufacture.
Syringes stored in fridge at low temperature shall be warmed with hot air/ shrink tube gun / hair dryer / hot water…. to 40-60 deg. C for better viscosity of solder paste for use with this dispenser. If you have old solder paste mix it well with flux and you can use it for testing on some old PCB.
