Electronic manufacturers are expecting to modify placement and reflow processes upon embarking on lead-free assembly. But the new materials also require significant adjustment to the pre-placement, mass imaging, process. DEK’s Global Application Process Engineering team performed a design of experiments to investigate the nature and extent of the likely modifications. Some, including the dependence on aperture characteristics, were expected. Others, such as the additional sensitivity to separation speed, were not.
We will prepare your DEK machines, design your process and tooling and even take care of training your core team to ensure that your site is truly prepared for high volume production. The entire project will be managed according to our Site Implementation plan. You can be sure of consistently high first pass yield.
Stencil set
 Provide stencil design from gerber data.
Supply stencil. Incorporating ProFlow design rules, ensuring suitability for the application.
Verification of stencil to meet design spec before delivery to customer thereby ensuring first time success. | |
Tooling
Provide design for tooling from Gerber data or CAD drawings.
Further discount of 10% given if tooling purchased from DEK.
Tooling types designed to accept singulated substrates or boats using our virtual panel tooling. Strips, panels or circuit boards using vacuum tooling. Silicon wafers using our universal wafer pallet. |

Machine benchmarking
Process dependent Critical Success Factors checked off.
Machine audit and benchmarking service ensures machine is sufficiently clean, accurate and level.
Includes 1 day on site support additional to time taken to fit any necessary upgrades i.e. ProFlow MPU. |
|
Training Core team training
Sufficient Operators, Technicians and Process Engineers will be trained to ensure readiness and competence of core team.
Includes 3 days on site training tailored to meet your specific need
Includes supporting documentation
Site Training plan developed to meet extra training needs for high volume ramps.
May require extra training where personnel are not already SMT ready |
