The Σ-G5S II retains all the features of its predecessor, including the high-speed high-accuracy rotary direct-drive head, the overdrive motion for highly efficient production by picking up components from either the front or rear feeder on the machine, and the Super Loading (SL) feeder that facilitates splicing-less*1 component supply. It also gains new head designs, an improved PCB feeding sequence, an enlarged internal buffer size for feeding larger PCBs and more to improve productivity. Additionally, its mounting speed of 90,000 CPH*2 (under optimum conditions)*3 represents an improvement of approximately 20% compared to the Σ-G5S.
Quality has also been improved by extending the detection range of components held by the mounter to immediately before placement. In addition, reliability has been further enhanced due to better balance for the beam motors to bolster stability, lower internal temperature by improving cooling performance, extending the service life of important components like the high-speed multi-purpose head and more.

*1: Eliminates the need to splice new tape to the existing tape being used when feeding components into the tape feeder, the device feeding electrical components.
*2: CPH (Chips Per Hour): Total number of chips that can be mounted per hour (unit time). Indicates processing capacity under various conditions.
*3: Mounting capacity (CPH) under optimal conditions using a 2-beam high-speed multi-purpose head x 2

1) Two new head types in an evolution of the “1-head solution” to achieve high productivity: Accommodates super-small 0201 (0.25 × 0.125 mm) size components and large components

Both the high-speed multi-purpose head and multi-functional head have been further enhanced in pursuit of Yamaha’s “1-head solution” concept to accommodate a wide range of components without the need for replacing heads while maintaining high-speed operation.

High-speed multi-purpose head with extended life: While the nozzle count remains at 15, due to weight reductions and higher output from the direct-drive motor, mounting capacity per head has increased by approx. 20% to 45,000 CPH (under optimum conditions) compared to the Σ-G5S. At the same time, the Σ-G5S II has the versatility to handle a wide range of component sizes, from super-small 0201 size components to larger L44×W44×H12.7 mm components. Important parts like brushless slip rings and high-rigidity couplings have been reengineered to offer longer service life and improve reliability.

Multi-functional head: In addition to increasing the number of nozzles to three, the frame rigidity has been increased to boost mounting capacity per head by approx. 20% to 10,800 CPH (under optimal conditions) compared to the Σ-G5S. The Σ-G5S II accommodates a wide range of components, whether large or irregular in shape, from 1005 (1.0 × 0.5 mm) size components to L72×W72×H25.4 mm components, as well as connectors as large as 150×26 mm.

2) Extended detection range of components held for better mounting quality

Previously, detection of held components was limited from pick-up to component recognition, but now extends to immediately before placement. The high-speed multi-purpose head uses a side-view recognition camera to track components and identify them, and allows the operator to select from three detection timing modes (for high-speed nozzle components): 1) arrival on PCB, 2) during placement operations, or 3) immediately before placement.
The multi-functional head uses nozzle flow rate to detect holding state from after component recognition to immediately before placement (not applicable to some parts sized L5×W5 mm or smaller).

3) Larger internal buffer size to reduce feeding loss with large PCBs

By improving the feeding sequence, PCB feeding time has been reduced from 2.0 seconds to 1.8 seconds. In addition, PCBs can now be put on stand-by across mounting areas and the buffer space in front of the placement area has been increased from 280 mm to 410 mm. Feed time is up to 55% shorter than with the Σ-G5S, thereby improving productivity with the applicable large PCBs.

4) Further detail revisions and refinements for added reliability

The load subjected to the left and right motors when the beam is being driven has been balanced by changing the cable positioning and more. This suppresses motor heat buildup to reduce device deformation and vibration.
Improved cooling performance also reduces the mounter’s internal temperatures. This not only helps stabilize machine accuracy, but also extends the service life of hardware components.

5) Compatibility with previous models

The Σ-G5S II is compatible with the main optional features available for the Σ-G5S, such as the nozzles, tape feeder, trolley and nozzle stocker replacement parts. Clients already using the Σ-G5S can purchase the Σ-G5S II with the confidence that they can continue to use their current assets.
