ProFlex heralds high throughput printing at ultra-fine resolution
ProFlex™ heralds high throughput printing at ultra-fine resolution
Keywords: Printing, DEK, Imaging, Surface mount technology
New ProFlex™ technology, introduced by DEK, will enable high accuracy mass imaging to surpass resolutions of 150 μm in commercial volumes. By extending process capability in this way, DEK has opened the door to high volume manufacturing of next generation component packages requiring fine-pitch area grid arrays, and to SMT assembly of next generation chip-scale packages.
ProFlex will be available as a factory fitted option for new machines, and as a machine performance upgrade (MPU) to machines already in the field. It is the result of in-depth studies into stencil behaviour during the separation phase. Because stencil separation has a significant impact on paste release, its influence over stencil cleaning requirements is particularly critical for very small apertures. The need to invoke frequent stencil cleaning cycles reduces throughput. By changing the stencils behaviour during separation, ProFlex minimises aperture blocking to reduce the number of stencil cleaning cycles.
"ProFlex changes the way the stencil moves during the separation phase, dramatically improving paste release and opening the door to ultra fine-pitch applications in high volume manufacturing," said DEKs Andy Ure, who led the ProFlex development project. "We also believe this is the key to challenging the stencil design rules for next generation applications," he concluded.
