Part tray video, Screen Printer Demo, TQ-100 Pinheck Board

Part tray holding FCC connectors and PSOCs
Part tray holding FCC connectors and PSOCs

I had a couple spare PSOCs to test the part tray with and train the pick and place. The PSOCs fit very well with little wiggle. Will be training the machine on the placement of the parts on Friday.

Here is a short little video of the pick and place positioning the FCC connectors onto the PCB panel. I am using double sided stick tape to replicate the holding force of solder paste. The pick and place is running at 10% speed to prevent the connector from sliding off the nozzle.

This is the screen printer we are currently using at MacroFab. It is an old semi-automatic printer but it works well for its age. It has a vacuum table to hold down the pcb and suck the screen to the pcb. Put some coated stainless blades on it for smooth paste squeegee action.

The Pic-32 on the Pinheck Pinball System is a TQ-100 package which is .4mm pitch. We used a solder stencil and placed the part via the pick and place. Stencil was .1mm in thickness. Ran 25 boards and had no solder bridges.
