smartBULK Option

This module offers an automatic search for bulk goods components and the integrated component turning stati-on even fully automatically turns parts that are the wrong way up.The automatic component search alleviates and accelera-tes the production of the smallest series and prototypes considerably. The software automatically scans with the head camera for the required components prior to each assembly. In doing so, it even takes into consideration the component size in case a wrong component happens to be in the tray.The component turner can be positioned anywhere within the assembly area. Components such as resistors can be automatically recognised and turned base don their differing colours on the top and bottom. This means that such components are always positioned the right way up.

Placement of loose components

To place loose components efficiently and solid, the placePRO offers a special developed procedure for pickup single components.The placePRO is not only able to take single components out of the feeder. It also provides the possibility to mark various components for pickup before the actual place-ment.This allows the operator to start an automatic placement of loose components after setup of the machine.While the machine is placing the operator can proceed with other jobs. If not enough components for placement are available, the intelligent software solution asks the operator to define more pickup positions.This also happens optimized to have a low amount of work.

A pick and place machine used for low volume SMT assembly is assign to new tasks almost every day. The component range is almost unlimited capacious. The structures are always getting finer and smaller on rising demand of assembly quality.QFPs, BGAs and QFNs are on order of the day, but basic chip- and SO-components as well.Especially for prototypes and zero series expensive equipment is necessary.The placePRO is the link between manual picking & placing and with special equipment and flexible pick & place full automatic machines. For the first time it combines the advantages of these different systems.

Feeders

4

Tape-strip feeder

When assembling prototype runs, tape-strips are often used. With this feeder, up to ten 8 mm strips (or fewer, but wider strips) can be fed simultaneously.

Tray feeder

Multiple tray feeders can be used inside tje placement area. Thus the placement area of the Pick & Place machine can be adapted easily to different projects and tasks.

Loose-component feeder

The loose-component feeder for the placePRO includes 36 pickup positions.Every tray has a clear cover, to keep the components shield and clean from dust.

IC feeder

25 different ICs can be equipped on the IC feeder. Therefore it has inserts with three different widths for different applicable compo-nents.

These inserts can be adjusted on custom made projects.

F proof

The sophisticated placePRO machine concept allows not only the placement of loose components and small series. At rising quantities or also as mix-armament smartFEEDER can be adapted on the placePRO as well. With the smartFEEDER-kit the placPRO can become a fully-fledged pick and place machine placeALL 510.

Accurate component centering

6

The placePRO is equipped with a Laser centring system, mounted directly on the assembly head and also with a vision-system for the alignment of multi-pole components like QFPs or BGAs.After picking the component out of the feeder the appropriated alignment will be chosen depending on the component. This centring ensures that the component will be placed on the right position with a higher accu-racy as possible with manual placing.

Laser centering

The laser centering system is mounted directly on the as-sembly head. It projects a laser beam onto the component using a laser diode. The component is measured by rotating it and analyzing its shadow length.While the head is moving towards the placement position, the measurement of the angle and position takes place. This centering method results in a high placement speed compa-red to an optical centering system.For components:•Chips≥0201upto32×32mmandpitch≥0.6mm

Optical centering / Vision system

The Vision system captures a picture of the component witha stationary camera. The image recognition software then measures each pin or the outer borders of the compo-nent and computes the corresponding correction factor.Applicable components include: •BGA,CSP,FPupto45×45mmandpitch0.4mm •Customcomponents(connectors,wiredLEDs,etc.)

Component library

The component library contains over 300 component models. This represents one of the biggest libraries on the market today. All content items can be edited or new ones can quickly be created.

Component Editor

If components, which are not part of the default library, need to be placed, a graphical editor is used to create a new component body in just a few steps.

Teach In

To create a project, the user drives the head to the particular position; a virtual component is shown as an overlay in the camera window. The virtual component can now be adjusted exactly and brought into the right position. After that, its position is logged into the Pick & Place pro-ject file.

CAD data converter

CAD data from any CAD system can be inter-faced easily to the projects using a format edi-tor. The conversion process is very fast and can be done offline on a separate PC. During this process the Pick & Place machine can continue to be used for its main task of placing compo-nents.

Virtual Inspection

After acquiring the CAD data the virtual ins-pection can be used to simulate the Pick & Place process. The camera moves across the current circuit board. At each placing position the cor-responding component is blended in virtually.

The position and polarity of the component can be checked and corrected if necessary. In this way error-free prototypes can be produced in a very short time.

Automatic fiducial recognition

To set up an assembly, reference marks such as crosses, circles, rhombi etc. can be read in automatically. The camera captures the exact position of the circuit board before the assembly begins.

Monitoring the placement process

To inform the user of the current status of the Pick & Place process, the circuit board is shown on the monitor. It displays virtual components one-to-one with the real assembly.

Automatic kitting control

The automatic kitting control checks the first component delivered from a newly kitted fee-der using a measuring station, checking the va-lue and tolerance. Wrongly kitted tapes can be quickly recognized and can be replaced before the assembly process starts.

For demanding applications such as defense, medical engineering or aerospace, where very precise components are used, each part can be checked before it is placed. Only components, that fit into a pre-defined tolerance range, are allowed to be used.

The entire Pick & Place process is continuously logged in real time, and can be accessed for SPC and traceability.

Variant assembly

Where a circuit board is produced in different va-riations, the placeALL® software can handle the possible variations independently. When selecting another variant, only the corresponding combination of characters (AB, AC, BC etc.) needs to be entered. This selects the variant to be assembled, so changeo-ver times are reduced greatly.

Traverse path optimization

Before production starts, the optimal traverse path for the project is calculated. Optionally the software displays the feeder positions that would reduce the assembly paths further to increase the placement speed. This optimization is especially efficient when producing a large number of boards, and when the machine is used in line.The optimization process is applied in a similar way when dispensing (see picture on the left).

User management

The user administration makes it possible to assign different rights to different users. The person who is able to edit programs or update component libraries can be defined, and other users can be locked out of these functions. These rights can be easily edited by clicking on the different production steps in the software.

Service kitRemote access to your machine by our technicians is possible using the service kit, after having your approval. This connects us directly into your placePRO® and the installed software to rapidly provide an overview of the machine’s status if any questions occur.

Dispenser

When producing short runs and prototypes, it is best practice to dispense solder paste or glue with the au-tomatic placer and afterwards assemble the components. We offer two different types of dispensing Systems: The simpler Time-pressure-system is mostly used for solder paste/glue with coarse structures. The patented dispensing System CD-04 offers maximum consistency by monitoring and controlling additio-nal parameters like temperature, fill-level of the dispensing box etc. It is microprocessor controlled and can dispense minimal amounts down to 0.001 or up to 10 mm³. By this method, it is possible to dispense paste for Fine Pitch components with a pitch of 0.5 mm with accuracy.

Software modules overview

PABarcodeAll smartFEEDERs can be set up using a wireless barcode reader. Together with the warehousing module you can read out the current stock. By using the reader for a setup, it is ensured that the correct component is set up on the correct feeder.

Order number: 908. 230. 310

PAOffline

With this CAD conversion, assembly and dispense data as well as the whole libraries can be edited at a separate workstation. The processed data can be transmitted to the Pick & Place machine afterwards


This module manages all SMD parts, circuit boards and other components used in production (like heat sinks or other standard parts) that you have in stock. The assembled components are debited from the stock automatically as they are used.

PAStatistics

To calculate an order, all available data such as assembly time per circuit board is documented and analyzed by this module.


PAOrder

Together with PAStorage the minimum stock level is shown and, if necessary, components are reordered from the sup-plier after the user has confirmed it in the system.

PANetstateAll machine messages are transferred to a separate PC on the network and displayed there. The user is informed i.e. if production is finished and can initiate further steps.


PATraceThis module documents which component from which lot has been used on which circuit board and with which order. This enables historical production runs to be interrogated, in case of a recall enquiry.


PAJobsAs production setups or change-over times are the most cost-intensive activities, PAJobs analyzes which of the predefined orders takes least time to set up and suggests it to the user for production.


PAsmartBULKThe optional smartBULK module offers an automatic search for bulk goods components. Before picking the software is scanning auto-matically with the head camera to find the right components. The integrated component turning station even fully automatically turns parts that are the wrong way up.

Order number: 908.230.356

The user is informed by settable minimum stock levels, whether a stock item has to be reordered. PAStorage distinguishes between the whole warehouse and the parts currently stored on the machine. This unit is the foundation of the modules PAOrder, PAlnventory and PAJobs.

Stencil printer

In order to apply welding paste or adhesive onto the PCB, we offer manual and semi-automatic stencil printers. In the case of the semi-automatic stencil printers, they work with an automatically fed double scraper with a freely definible contact pressure.

Semiautomatic manipulator

Für den Aufbau von Prototypen und kleinen Serien sind manuelle und halbautomatische Manipulatoren in unserer Produktpalette. Diese Manipulatoren führen sämtliche Prozessschritte vom Auftragen der Lotpaste / des Klebers bis zum Bestücken von Bauteilen inklusive Fine-Pitch aus. Je nach Anwendung können die Geräte mit Zuführeinheiten für Rollen und Stangen versehen werden.

Inline system

To achieve a higher placement rate and to be more flexible, multiple Pick & Place machines can be chained. The placement positions are split on demand, so either both mach lines handle the same product or two products can be assem-bled at the same time. Kitting times are further lowered by the raised feeder capacity.

Reflow oven

We provide different standalone or inline reflow sol-dering systems with approved glide zone heat cham-ber system for lead-free or leaded soldering or the curing of glue. Outlines of boards or components can be easily measured and analyzed using the integrated thermal sensor. Several multi-channel measuring inst-ruments are also available.
