71281610 – The Heavy Weight in Surface-Mount Technology

The Alwayse 71281610 Hevi-Load Unit is the go-to product for all applications that require a durable and reliable unit. Surface-Mount technology (SMT) is a method in which electrical components are mounted directly onto the surface of a printed circuit board (PCB). PCBs are used in virtually every electrically powered item – from smart light switches to mobile phones, washing machines and cars.

Traditionally, the PCB assembly process was undertaken by hand, where a human would painstakingly pick and place components using a pair of tweezers. Fortunately, PCB manufacturers nowadays have automated this step using the pick and place (PNP) machine, as machines are more accurate than humans and can work around the clock.

PNP Machine

A PNP is a robotic assembly device that uses a vacuum to lift a component off of a piece of tape, rotate it to the right orientation, then place it on a circuit board. It takes a few hours to setup a machine to build the assembly, but once running, it is very fast. The top-level machines can place up to 30,000 items per hour precisely on the base PCB plates.

To achieve this speed, the machine needs to move in all directions and the support for the arms needs to be very strong, durable and able to rotate 360 degrees. Alwayse Hevi-Load units are the first Ball Transfer Units featuring a CNC machined load pad to enable heavy loads to be effortlessly handled.

Our innovate load pad design results in no loss of load rating in the ball up or ball down (castor) position. This is when compared to other ranges where a 50% load reduction is typical.

Alwayse the Right Choice

You can use the units ball up or ball down – giving the machine designer increased flexibility. As a result, the Alwayse 71281610 Hevi-Load Unit is the go-to product. For all applications that require a durable and reliable unit. And that can move 360° without and fatigue or wear.
