ESSEMTEC will display the HLX Series, a high-performance placement system series for flexible SMT manufacturing at SMT/Hybrid/Packaging on May 30 to June 1.
The series features production speeds up to 22,000 cph and a large feeder capacity (192 tape and stick feeders). 16 JEDEC trays can be used without loss of any feeder space. The series is comprised of the HLX8100 and HLX8200. Can be changed over during operation-- without standstill. On-the-fly setup modification ensures maximum machine load even with small productions series. Linear drives are maintenance-free, fast and precise. They position the placement heads precisely in the x- and y-axes. During placement, the board is fixed.
“Collect & Place” method enables high-placement performance. HLX8100 comes with one placement head with four vacuum nozzles and HLX8200 has two placement heads with a total of eight nozzles working in parallel. Cognex Vision (SMD4) enables precise, fast alignment, and checking of components. With transparent lighting, illumination is independent of component type and image analysis is reliable.
All feeders are exchangeable and refillable during operation. The systems are optimized immediately after every feeder change.
Are laid out for rugged, long-term operation at three-shift workdays. The chassis and wear-resistant linear drives allow for high acceleration of placement heads. The gantry system permits the simultaneous operation of two placement heads in parallel. While one head retrieves four components, the other uses this time slot for placement.

VacuNest Shape Memory Tooling combines the benefits of a custom tooling plate with the versatility of pins. An antistatic membrane covers a foam former surrounded by polymer granules. Place a golden board onto the modules, press down, pull a vacuum and the memory of the board shape profile is held. The chambers are profiled to the shape of the underside of the board ¾ on activation of the vacuum this shape is now held. Simple, secure and a custom board support is created within seconds. The shape will be held for weeks/days/months until the vacuum is released, whereupon the modules return to their original form, awaiting a new set up for the next version of board.
Advantages include: no risk damage to a component due to the pin/printing pressure, support forces evenly spread over the entire board, firm and precise support, ease of use, no dedicated tooling and short payback period, and the tool can be simply reset when a board version changes.
Can handle high-density boards and requires little to no lead-time.
Applys firm force consistently to the entire board. Guarantees board flatness and is not sensitive to solder paste contamination.
The 23" SP200 avi inline stencil printer is designed for medium and high throughput, high-mix applications.
Uses a “look down, look down” approach to vision alignment. Twin roving cameras mounted on independent X-Y gantries ensure accurate, repeatable precision alignment using fiducial marks or PCB/stencil features. This facilitates a “paste on stencil” inspection feature to determine if adequate paste is on the stencil before running the print cycle.
Selective Auto-Paste Dispense technology is fully programmable. The advanced intelligence of the twin camera vision system analyzes the stencil to see where paste is required, and the dispenser deposits it accordingly.
The user interface runs under a menu-driven, Windows XP application and is simple to operate. Incorporates comprehensive self-diagnostic capabilities, including production logging and automatic fault report generation
Data stored on the machine may be accessed remotely via a PC modem connection, allowing for “on the fly” troubleshooting. Automatic rail width adjust is standard to help with quick changeovers. Stencil loading is automatic; does not require adaptors for varying sizes of stencil frames. Speedprint Technology, speedprint-tech.com Hall 7, Stand 116 (with ANS-Answer Elektronik)
