TQ-100 test placement on a Madell DP2600-2 Pick and Place

The Pinheck Pinball System uses a PIC32MX795F512L-80I/PT mcu. It is a 32bit mcu running at 80MHz with 512KB of program space. Plenty fast enough for pinball. The only reasonable package it comes in however is TQ-100 package which has a pitch width of 0.5mm. This pushes the limit of the vision system of the DP2600-2 but I managed to get the system dialed in to make the placement.

The PIC32MX795F512L-80I/PT is a tray part so the machine does not pick the part up from a feeder. Instead you line up all the chips in a row and the machine knows where to look for it. Uses the vision system to find and locate the part.

After picking up the chip the machine takes it over to the “Uplook” camera. Here is can make sure the part is oriented correctly and lined up.

The machine then moves on over to the part location on the PCB and places the part. In the image you can see the dark areas between the shiny leads of the PIC32. The dark areas are the solder mask showing through which means the part was placed correctly and straight.
