Universal Instruments GSM 4681A SMT Placement 4Techusa.com

4TECH Electronics Inc. is a global buyer, service provider and supplier of Circuit Assembly equipment. This video is a Universal Instruments GSM Model 4681A SMT pick & place system that is for sale.

Safety systems, guards and panels were removed by our Engineers to film this video.

The machine is placing components on FR4 material PCB that is 23" (584.2 mm) length by 3.675" (93.34 mm) width and .062" (1.57 mm) thickness. This machine will assemble even larger PCB's in both length and width and handle nearly any component. From 0201 to the largest bumped array, and a variety of odd-from parts.

Simple and typical, passive and active components were used to demonstrate basic machine operations only. No effort was made in terms of programming to place components on a specific target, only in general area. However, the SOIC16 parts were programmed for body length plus .0005" (.0127 mm). In the video they appear to be touching, and they are. This is do to component body variation.

This machine has two 4 spindle High flexibility placement heads and two automated nozzle changers. Only one head is used as speed and optimization were not a consideration for this video. The focus was on general operations. Where considerably higher levels of productivity are required we simply bolt on the 7 Spindle high speed heads with "vision on the fly" capability for around 10,000 CPH.

When dispensing is needed we simply remove one of the heads and replace it with a high speed 4 spindle dispensing head, or run a combination of both enabling paste, adhesive and component placement, and or part-adhesive-part, that is a part on top of a part with dispensed product in between with solder paste at the bottom. All on a single machine.

You may notice the monitor displaying vision inspection results. You may also notice the machine placement heads make a unusual move to the far side of the machine. This was to place a component on the reject collection conveyor as it failed the programmed vision inspection requirements. At the end of the placement/assembly process another unusual movement can be seen. That is, the machine automatically replacing the missing part that failed inspection.

The system makes use of multiple cameras and a high speed vision system for a variety of tasks. including; inspect of components and their features, such as bodies, leads, bumps, PCB alignment, component to spindle alignment and part to pad, and more.

This machine is capable of far more than we can demonstrate here. The flexibility, accuracy, reliability and low cost of ownership for this model are known globally. We maintain a large diverse stock of these machines for nearly every need and budget. We also provide complete service, training and support them in every aspect.

Why do you use the Belt Reject Station for dropping components? Didnt the Head reach the Dump Bucket? If you optimize that product you can save more time. you should, for example, insert repair steps before the head change the nozzles. Nozzlechanges waste the most Time.

[4TECHelectronics]

Thanks, we know. we optimize all machines and complete factories.

This is just a short vid to show basic operation to those that are not familiar with the equipment. No production intent.

[HerZong]

Is there any school teaching how to program these machines and maintaim them?

This is a tape board..

Why mount small chip at GSM?

Using HSP is much faster.. GSM is for biger & heavy part...
