The PCB flipper is used for angle of 90 degree to 180 degree when do the rotation of double-side PCB board, which is suitable for the double-side of PCB board assembly process.

ElectronicsTalk offers the high-standard PCB flipper. When a double-side PCB board finished its front work, the rear side will need to be flipped by the PCB flipper to keep a continuous flow of SMT line.

It adopts the PLC control system, steady and precise lifting driven by servo motor, width adjustable by screw, and size can be customized. All of the core parts are imported from credible companies, ensures high-efficient performance.

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.
