I think your pre-heat temp is a little low for SAC 305 Soldering. Especially with a Pallet. You might want to try to add some time and temp to get the PWB itself preheated up to 150-160C. That should help with the barrel fill. Make sure your board

I am having solder barrel fill issues on THM component, we follow, we follow IPC 610 E requirement. The barrel fill issues happen on signal & ground pin at connector & E-cap. I found out that most of the insufficient solder happen on the connector ag

Kester is proud to announce the launch of SELECT-10™Selective Solder Flux, a zero-halogen no-clean liquid flux designed specifically for the needs of the selective soldering process. As part of Kester’s portfolio of high reliability products, SELECT-10™ has passed IPC SIR testing as a raw and partially activated flux. Sustained activity within the flux allows for good barrel fill in challenging and high temperature applications. Specific to selective soldering, SELECT-10™ does not spread beyond the spray pattern and will not clog nozzles. SELECT-10™ is classified as ROL0 flux under IPC J-STD-004B.

The drive towards fine pitch technology also affects the soldering processes. Selective soldering is a reliable soldering process for THT (through hole) connectors and offers a wide process window for designers. THT connectors can be soldered on the top and bottom side of boards, board in board, PCBs to metal shields or housing out of plastic or aluminum are today's state of the art. The materials that are used to make the solder connections require higher temperatures. Due to the introduction of lead-free alloys, the boards need more heat to get the barrels filled with solder. This not only affects the properties of the flux and components, but the operation temperatures of solder machines become higher (...)First the impact of temperature will be discussed for the separate process steps and for machine tooling. In the experimental part measurements are done to verify the accuracy that can be achieved using today's selective soldering machines. Dedicated tooling is designed to achieve special requirements with respect to component position accuracy.
