Fully closed design with turn limiter grantees the highest level of safety. Different sizes are available in terms of customer specify.
Understanding PCB Flipping Machines
PCBs serve as the backbone of electronics, undergoing multiple assembly steps like solder pasting, pick-and-place, reflow soldering, cleaning, and testing. Achieving consistently precise alignment is vital at each step. Manually flipping PCBs can vary in orientation, negatively impacting quality. PCB flipping machines enable reliable and accurate 180° rotation automation.
PCB flipping machines automatically grip PCBs, rotate them 180° into the desired orientation, and then precisely place them down onto the next production stage. This allows fast and consistent alignment changes between different assembly processes, eliminating reliance on manual labor.
They are also referred to as:
PCB inverters
PCB rotators
PCB turners
Types of PCB Flipping Machines
**Pneumatic Flipping:**
Compact machines using air cylinders for flipping force.
**Servo Motor Flipping:**
Controlled servo motors enable precision speed/angle.
**Conveyor Flipping:**
Rotating conveyors turn PCB sandwiched between belts.
**Robotic Flipping:**
Industrial robots provide programmable multi-axis control.
