The linear fluxer is a peripheral module that can be used for flip chip placement or PoP applications on the Juki KE2060 and KE2080 flexible placement machines. The linear fluxer is fully automatic and generates a constant liquid media film of flux or adhesive. The fluxer can be installed at the factory or can be easily retrofitted in the field.
Juki machines are ideally suited for PoP (Package on Package) applications. PoP is a placement method which allows a higher vertical placement density and makes a component construction kit possible. Memory components can, for example, be placed freely onto logic modules creating a more cost effective solution that allows memory size to be freely adapted to the market needs.
Components used in PoP applications are usually BGA or µBGA and, depending on the placement process, at least the upper component has to be fluxed at the solder bumps in order to secure it and to prepare it for the reflow process.
The most common type of adhesive used is conductive adhesive. It can be used to dip a part into the film or to stamp a tool into the film and then transfer the acquired media onto an object or substrate often referred to as "pin in paste" or "adhesive pin transfer".
Plates can have 2 different depths and/or sizes per plate, one cavity on each side of the plate
Cavity size max 30mm x 30mm
Constant film height due to linear movement during filling of the cavity ("doctor blade" style operation)
