Der Spannrahmen ermöglicht eine direkte Montage der Schablonen und kann in LPKF-Druckmaschinen wie dem LPKF ProtoPrint eingesetzt werden.
Der Spannrahmen passt in fast alle SMD-Druckmaschinen und unterstützt den schneller und einfachen Austausch der Lotpasten-Schablonen ohne Kleben.
Er gewährleistet eine gleichmäßige Spannung über die gesamte Schablonenfläche, ist einfach zu handhaben und erleichtern die Reinigung und Archivierung der Schablonen.
In a typical SMT assembly line stencil printer several pick & place reflow oven and optical or automated test systems are included. Quality and cost reduction are primary goals of today’s circuit board producers and buyers. Precise space deposition is a key-issue for achieving low defective rates.
With the selection of the LPKF ZelFlex Z4P tension frame your production cost will be additionally reduced while your flexibility and quality will be increased. Only a few steps are required to exchange a foil:
Release the air from the system using the air supply connector. Unlock and remove protection bars from the frame. Take the old stencil off, position the new stencil on the pins. Fix the stencils with protection bars, apply compressed air, wait for a few seconds and the LPKF ZelFlex frame is ready for a new printing process.
The LPKF ZelFlex four-sided pneumatic tensioning frame provides: simple and rapid foil exchange, repeatable perfect four-sided tensioning and cost reduction. Achieving even and high tensioning is the result of our unique patented design.
With years of experience in SMT printing and the production of mechanical frame behind us, our goal was to develop an entirely new product which eliminated all known disadvantages of tensioning frames currently available.
Straight forward engineering ensures reliable and easy use. The functioning of the frame is very simple and therefore reliable. Compressed air is supplied into a flexible tube and distributed to all four sides. As the air pressure rises, the tube expands and it moves all four tensioning bars apart simultaneously.
With an advanced perforation and tensioning bar design optimal pressure distribution is guaranteed. The patented ZelFlex perforation layout can be reproduced roayalty-free. Rigid aluminum profile tensioning and protection bars are specifically designed for this application.
All parts are designed and produced using CAD/CAM systems. Precision machining guarantees consistent high quality production. Each frame is individually assembled and tested to ensure a very high standard. Our implemented procedures have gained us ISO 9001 accreditation.
The LPKF ZelFlex Z4P is produced in various dimensions to fit your printing machine and allows optimization to the required printing area. Optional adapters provide further flexibility. Special options are also available, such as a built-in gage which indicates air pressure within the frame.
The LPKF ZelFlex Z4P comes with many benefits. Lower production costs. Only one frame is necessary. The same frame can be used for multiple projects. The foil is clamped directly into the frame without the need for glue. No need to buy new frames or recycling old ones. Less storage space is required. Only frameless foils are archived.
Quick changeover time. Stencils can be changed within 1 minute. Washing of stencil is simplified: Only the stencil is washed. Elimination of glue and cleaning agent compatibility problems. Your production quality will be improved, stencil held in equally distributed tension.
Repeatable tension levels without the risk of long term tension level decay. Reduced risk of damage while stencils are archived. Print area of ZelFlex foils is larger than with meshed frames. Some additional advantages of the ZelFlex Z4P. Air pressure can be adjusted to suit foil thickness. Once the foil is held in tension, the air supply is disconnected. No special docking station is required to change stencils.
Exchanging foils is quick and easy. And last but not least, using the LPKF ZelFlex frame is also friendly to the environment: no need for glues and lacquers, reduced use of cleaning solvents.
