Staying ahead of customer requirements
At NOTE Windsor we have 4 fully integrated surface mount lines. Each line has a DEK printer, 3 Siemens SiPlace component placers and either a 5 or 7 zone Omniflow oven all connected with conveyors and un-loaders.
Prototype through to volume capacity
To keep 12 pick and place machines producing assemblies every day takes great organisation and preparation. To that end we have invested in an off-line set up area that allows us to have the next job set up and ready to go on feeders and carts for each line.
Setting up a job used to take a whole shift, whereas changing the line from one job to the next now only takes us 30 minutes.
DEK NEO Horizon screen printing machine
Windsor have invested in a DEK NEO Horizon screen printing machine. With advances in machine design and technology, the new machine is far more accurate in the alignment of the stencil to the board.
The coplanarity presentation of the board to the stencil is greatly increased across the board surface area giving a superior gasket seal between board and stencil resulting in improvements in printing. The process repeat accuracy of the system is up to +/-20μm.
With the options we have equipped the machine with, it will enable us to keep a tighter control over the process resulting in higher yields:
This a 2d inspection system that scans each board after it has been printed looking for potential print errors, if a failure is detected the machine retains the boards and alerts the operator highlighting the problem areas, the operator is then able to examine the error and take the appropriate action to rectify the situation.
This is a low volume dispense system that provides functionality to the printer and allows us to accurately dispense small dots of glue to retain large components in place during the second side reflow process.
Roll Height Monitor
The machine is equipped with a laser that measures the height of the roll of solder paste on the stencil, this ensures that the amount of paste on the stencil is always maintained at the optimum level to ensure a perfect paste roll during the printing process.
