Working with warpaged PCB's in Pick & Place machine
Using the board warpage measurement software tool, that laser measures and calculates the precise board surface levels, on each board.
Based on the advanced surface measurements a simulated leveling is created, that compensates for the PCB’s bend surface, in the component mounting process.
➡️ Taking back accuracy that warpage causes loss of.
Board warpage measuring software for pick & place machines is available to YAMAHA mounters.
Handling double-sided PCB assembly process
Fact
After first side soldering, warpage is a factor you need handle,
as a level and supported surface is key for accurate component mounting.
Supporting PCB's in double sided PCB assembly
After completion of first side of the PCB assembly, it is time to mount on the PCB's second side.
In-between the already mounted components on the first side, supporting pins are set below the board before the crucial second side mounting.
Due to space limitations for the supporting pins, on the already mounted side, focus on extremely accurate pin support placement, calculated from Gerber data, to set your supporting pins:
➡️ to create optimum support for second side mounting
➡️ to not to disrupt the boards finished first side
So you see, no matter the amount of warpage, pin support set below the PCB in the component placement is relevant.
YAMAHA SMT offers timesaving automatic pin support placement & exchange system option for their Pick & Place machines that uses Gerber data to take precise pin support placement to a higher level.
