Essemtec Flex/Film Placement Machine Gains Twin Vacuum Table
August 14, 2008 |Estimated reading time: 1 minute
AESCH, Switzerland Essemtec developed a dedicated twin vacuum table for its FLX2011-MKL placement machine to facilitate handling of flex boards and film substrates. The table also is able to double productivity.
Essemtec designed the reportedly cost- and time-efficient solution for the reliable flex board handling with a leading manufacturer of plastic film keyboards. The twin vacuum table has twice the size of the former table and its ends protrude alternately from both sides of the placement machine. The robust table features a pneumatic servo drive that moves easily and is vibration-free.
Handling tasks can be completed comfortably on the protruding side of the table, such as the placing of cover films, removal of assembled flex boards, and the application of new film substrates. During this time, paste can be dispensed and components can be placed on the other end of the twin vacuum table in the machine. The subsequent vacuum table can be moved to the other direction and the handling/assembly cycle started again. Depending on the complexity of the flex board and the keyboard, the twin vacuum table allows for doubled productivity, since handling and assembly are taking place concurrently.
FLX2011-MKL is a multifunctional production cell designed for the assembly of plastic film keyboards and flex PCBs. The cell automatically dispenses solder paste, conductive adhesive, and other types of glue, and places SMDs and metal domes from various suppliers.
The 800 × 600 mm vacuum table can process large single flex boards or multiple smaller boards at one time. The basic version of the FLX2011-MKL is designed for high accuracy, reliability, and durability. The company reports that it incorporated feedback from the more than 500 machine installations to design the application-specific custom table.
